Title: Detailed Restoration of a Bally 1090
Post by: David Walz on March 12, 2018, 08:50:58 AM
 :wave: Hello, I have worked on electrical projects in the past, so I'm confident that I can tackle this slot machine restoration. This forum is great for information on this 1090.


I have a lot of patients, time is on my side, and my workshop is full of tools to work on this properly. I


This 1090 has some issues and I decided to get some manuals to repair it, and this site is great for research.

Welcome to NLG!   :waving_flag:

Good luck on your project. The older machines are a beautiful part of the past. Feel free to post more photos of the interior.

The seller stated that everything works, the only issue is that the reels don don't align up properly for payout. I'm not concerned, since I'm going to restore the 1090.


The good part is the excellent quality of the 1090.  :yes:

The strip alinenent could be that the strips have moved on the reel tins, since they are just held in place by crimping the edges of the tins. The other possibility is that the screws holding the tins to the hub, or the indexing can to the hub are loose. There are steel roller bushings that are on the kick and stopping level for each reel. Make sure they are there. Welcome to New Life Games.  :wave:  Beware.. One slot machine tends to lead to 2-3 or more.  There like the movie gremlins they tend to multiply..

Overall, I don't think it's got to many problems. I think if I clean, and service the slot machine it will come to life. Since it's built in America, it should be a good machine.


I'm assuming that the plate with the model and serial number and the year it was made.

Ok.. I think the wires were from a counter, you can just tape them off. As for your wobbling gear, that a unit call the clock. Most do wobble. Now for tag. The too line is tha machine model, and the date the machine was made is is hand stamped in the Black above the word Bally.

Another mystery plug.

Title: Re: Detailed Restoration of a Bally 1090
Post by: Amechanic on March 13, 2018, 09:21:31 PM
Not every plug in the machine was used. The wiring was pretty much universal from machine to machine in these. Also some of the plugs and hold are from casino used item. Some machines were modified in there after life's too.
Title: Re: Detailed Restoration of a Bally 1090
Post by: David Walz on March 14, 2018, 07:27:28 AM
I stocked up on Molex plug accessories, after further inspection  I noticed repairs that were done by someone who didn't have the proper tools. I have everything I thought until I started reading about Molex plugs. That will be a lifesaver in restoring this slot machine.


As for the extra holes, i will have to plug them, and blend them in to the cabinet. The Formica cleaning will take awhile, I have some repair material ordered.


I noticed the key override or reset was damaged, actually it was the wires, electrical was ripped out since I'm going to restore this my plan is to rekey the doors and key reset alike to one key.


The power cord was damaged, im working on replacing that, with a way to service the slot machine removed from the base with a disconnect in place. The slot machine will be bolted down on the base like the factory.


This is a beginning to a great restoration. :)

Does anyone have a resource where I can finfinad a new 122-105 transformer. I would like to replace this one if I can. What is the output of the transformer, ac, dc, 12v, 6v, etc.


When I'm testing the lights, what source of power/voltage is generated by the coil so I can set up a test station.   :Scratch-Head:

Is there a problem with the transformer? Those 122-105 transformers can be hard to find. New may be almost impossible. I might know a person that may have one, but not sure what condition it's in.

You don't see them go bad very often, and usually when they do it's because someone put too high of an amp fuse in the machine. Then it's easy to tell because the transformer over heats and the transformer will have a melt down. Makes a big mess.

Thats stupid putting in larger fuses it defeats the purpose of the fuse.  :duh:

Most of the machines have or had a sticker on the fuse block or right above it with the correct fuse amp needed per voltage. Your main line fuse 110v usually 3 or 5 amp. The 50v for coil is 5-8 amp. The you have the 6V, I've seen those as high as 10 amp to 5 amp depending on how many small bulbs you have. If you can located a schematic for you machine, it will have the correct amp per voltage.

On to the reels.

I checked every wheel for the correct depth to the symbol on the reel and its dead on, every reel is on target, and the reels are in order.

Now, I need to check the next part.

Post by: David Walz on March 23, 2018, 08:50:56 PM
Well, it took me two days to figure out the reels and fixing a problem that others couldn't figure out. The number one reel was not spinning.


The major problem was grease goop that hardened up, then after studying the mechanism for hours I figured out the way it spins the reels. After that and knowing everything was working correctly, aligned, I adjusted the stop back 1/8" and all three reels work, the payout is correct and I'm really happy.

Moving on, the cleaning of the upper and lower cabinet continues. I must have gone over this cabinet a dozen times and im still removing gunk.


The top and bottom are now together permanently. I pity the fool who trys to move this beast without a dolly and a liftgate, however I'm not selling it so my family will have to deal with it when the time comes.  :24: :24: :24:

As of today, I've got the slot machine functioning correctly. Everything operates as it should. I'm ordering some missing parts to further the restoration. Seems that some people think that leaving parts out, screws out is fine. Now I'm having to hunt for replacement parts.


The previous owner stated that the slot machine worked, but it didn't pay out the coins properly. I cant see how this slot machine even lit up. The number one reel was stuck, the hopper motor was jambed from a upside down bearing, the fuses were not correct, the ground was missing, and the door had a ground short blowing the fuses. Most of the light bulbs were burnt out, or made in China. I found some GE USA old stock light bulbs and replaced all of them.


As I said, I need to work on the small defects like missing small parts, chrome trim that is good condition not rusted.

Title: Re: Detailed Restoration of a Bally 1090
Post by: David Walz on March 28, 2018, 08:04:14 AM

$200.00 for the slot machine, $50.00 for the belly glass.


HISTORY OF MY JOURNEY

Here in Alaska we don't have a lot of slot machines that come up on Craigslist, I wanted a good quality American made slot machine that was 100% quality made used in the casino's that were tough as nails.


I arrived here in Alaska five years ago, always scanning Craigslist for the right slot machine. I found a lot of those China made ones, cheap made inferior quality, but never seeing a Bally. Recently I saw this one on Craigslist for $200.00 that just came up for sale and I snatched it up knowing the true potential of this amazing slot machine. I didn't even plug it in knowing that at anytime the machine could be damaged if it was not wired correctly. I never plugged it in until I had gone through the machine and I was certain it was safe.


True to the name Bally its a tank, well made 100% American made that lasted several decades, the idiots before me really did a number on this slot machine, however it was mostly wiring, which with the find of the exact wiring diagram helped me figure out what was the problems, resolve the butchery, black tape issues, removing the black tape and repairing the machine back to Bally standards. Im looking for the wiring " catgut" rope to finish the job which is not hard to find.


THE BALLY MACHINE AND IT'S RESTORING


I have resolved many issues that kept this machine dormant for a long time, the wiper not setting on the first wheel, preventing the reel to spin, gunk in the reel bearings, cleaning all of the contacts inside the machine.


Dissembling the whole machine, cleaning every nook and cranny, every mechanical and electrial item was hand cleaned checked with a meter. I ripped out the electrical 110V power cord and installed the proper size for the machine, all of the fuses were replaced by factory required sizes, not the 20amp, or the 10amp fuses that were being used because of all of the shorts inside the machine.


The hopper was stuck, it did not move, finding out a bearing was upside down, and bare wires hanging didn't help. Replacing a ton of screws that were butchered, the safety timer was completely dry, at first it would not move easily, after cleaning and servicing it works as it should. Once the hopper was repaired, it runs flawless. The wires that were cut, I found out what they were used for and corrected them, if needed I used Molex plugs to prevent a short.


Parts are difficult to locate that are missing, however the mechanical parts will outlast since they are quality made, so when I find the missing parts all I need to do is maintain the machine, the electrical parts are not hard to find, most will never have any issues. Maintenance is important, and that will keep it running well.


Overall, the resale value will  be greater since the overhaul, all of the locks are keyed to one key, and the base cabinet matches the Bally slot machine. I have the upper and lower cabinet permanently attached, cleaned, and they are getting a buffing with something that will bring back the Formica to a nice finish.


Its going to be awesome. I just need some parts.
Title: Re: Detailed Restoration of a Bally 1090
Post by: David Walz on March 28, 2018, 02:47:22 PM
I've found the parts,  now it's time to get the cat gut and string the wires, only in places where the cat gut is missing in the wiring. The black tape doesn't fit in this slot machine, this way nothing will be different.

I hope to have all of the missing parts re-installed into the slot machine, this is what I need:

1) cover cap for the handle hub (page 96 from the complete service manual 1964-1980)

2) chrome glass belly retainer (page 98 from the complete service manual 1964-1980)
3) counter assembly with bracket (page 55 from the complete service manual 1964-1980)
4) scoop cover (page 79 from the complete service manual 1964-1980)
5) baffle assembly (page 79 from the complete service manual 1964-1980)
6) coin run down assembly (page 99 from the complete service manual 1964-1980) These are the only ones that are missing, everything is accounted for in the slot machine.

 :WeirdEyes: I'm amazed at how inept people can be. This poor machine has gone through so much butchery from people who were retarded.

I always wanted a 1960-1970 Bally slot machine, since they were 100% American made, and I was prepared to rebuild it to factory specifications, even in this condition, all I needed was a wiring diagram, and a good service manual. 

 :nerd:
The positive aspect of this Bally machine is mostly everything is there to run the machine, and I was able to locate original Bally parts.

 :garfield: Another note of a bright light idea, regarding the upper cabinet bulbs, you can keep the bulbs tight in the sockets
by adding a dab of solder on the bottom of the bulb, it works for me and I clean the bulb afterwards.


The cabinet is pretty much completed.

I'm anal retentive, everything has to be the best it can. The change bowl assembly was a pita to slide into place, someone loosened the screws to make it work.  :duh:


I was able to disassemble, re-build the whole thing to slide into the pocket with no resistance. I also replaced some ugly screws.


Some idiot drilled two screws into the top of the lower cabinet and I have a Bally ash tray that will cover them up.

This is one awesome slot machine!

My wife wants to play with the slot machine, however I'm not through putting it through its system check, however this Bally rocks, the manufacturer built some quality slot machines back then. Everything works great, no issues, no power problems, its a great machine and im really pleased with the outcome.


As  I said before this is built solid, heavy duty, it will be a great addition to my home, the cabinet is now really, really, nice. The slot machine looks good I replaced the middle glass which was flaking and the belly glass that had a chip missing.


BTW: what is this button inside the slot machine used for???????

I'm getting the bugs out of it.


The air cylinder was full of caked grease. I missed that when servicing the reels. IMPORTANT make sure the reel shaft lock springs up into place on the reels. If not its FUBAR, the previous owners didn't set them correct and I followed suit until  I realized that the shaft would not stay put. Then I looked at the book.  :banghead: 


This photo is the original one when I first got the slot machine, as you can see the lock is going down.  :fryingpan:
Title: Re: Detailed Restoration of a Bally 1090
Post by: David Walz on April 06, 2018, 09:02:22 AM
And dont forget to align the shaft lock plate.  :banghead:

YOU REALLY NEED THE BOOK "BALLY SLOT MACHINES"! It's a must to un-FUBAR the slot machine issues created by someone else who obviously is brain dead.


Between the book and the wiring diagram I was able to remove ALL of the wiring FUBAR'S remove all of the electrical tape, repair everything without anything being seen. Re-catgut the wiring, use the Molex connectors to straighten things out.


I've learned a long time ago that mechanical things like this needs a complete tear down, parts inspect everything, screws, nuts, bolts, parts, everything needs to be checked out, hands on, visual check on function. If not you will be going in circles chasing your tail.

Air cylinders are my first thing in these old machines. The rubber cup seal turns to a sticky tar. I just remove the old seal and clean up the mess it makes, then I apply a very thin amount grease on the steel piston and assemble. Do not use a large amount of grease or you will have a mess inside the machine as it squirts out of the air hole on the back of the air cylinder. Learned that the hard way.

 :thank_you:  I just noticed the difference in the machine pull, when I first got started, the pull was awful, then I serviced the handle mechanism assembly and it was 100% improvement. The air cylinder makes a lot of difference now its really slick as snot.  :dancing_2: :dancing_2: :dancing_2:

 :soapbox_3:

I contacted S** D**** Slots and the guy said that their time was to valuable to be taking online orders, sounded like he didn't want any more business.  :fryingpan:


I contacted S***** and C*****, he is someone who has no time for customers, I sent a email last week, on a Monday. I called Wednesday and talked to a person who acted like he would get my order together. After I flew back from Phoenix this Wednesday the same guy was on a road trip and was telling me he had the parts but was away from the office on a coin convention. So it looks like this guy will probably get around to my needs around Christmas. :talktothehand:


I was contacted by someone else who said he had some parts, however I found out he just moved and everything was in boxes. I appreciate the help, however if your parts are boxed up, you should unpack them before you say you have them.  :duh:


I have been in business for 40 years, I don't conduct business this way. If I'm not going to ship products I would state that on my website, I am courteous, if I'm going on a trip, I finish my business first. When I moved to Alaska my company was shut down until I had everything set to open shop, I had customers call me before I was ready and I told them I was not ready to open.


So who can help me with my parts? I'm not wanting to fabricate parts for this slot machine if I can get them, however, it seems I might have to. I really dont want to piss people off however I need this project completed before the snow thaws.

 :Coffee_Buzz: :Coffee_Buzz: :Coffee_Buzz:

What I need:



I have a Bally 1090-22 1979, I'm restoring the machine by factory standards and I'm looking for  items:


First, the lower display unit, specifically the chrome glass retainer looks poor compared to the rest of the slot machine. The glass for that model is 8" X 20".


Second: I am missing the counter assembly with bracket, which is located inside in the reel assembly.


Third: Hopper parts, scoop cover and baffle assembly.


Fourth: cover for the pull handle cap.


Fifth: the coin chute that drops coins in the lower cabinet. The one I have was damaged by the previous owner/technician.


I have the photos of what I need on the next post.

One thing I've learned a long time ago, take it slow and check out everything, even with that I still miss something sometimes, however you really need to examine the whole picture twice, take photographs, recheck the photos, and take as many breaks as you can.


As I was examining the reel assembly, I noticed  black tape on the wiring, I thought I had removed the ugly black tape in every nook and cranny, so now I have to work on the wiring today.  :banghead:  I can't believe I missed that, however the rest of the slot machine is definitely clear of the ugly black tape syndrome.

 :bubblegum:
If you are rebuilding a slot machine, I cant tell you how important it is to get rid of the black tape, that may hide something that will short the machine.

Every Bally that I’ve worked on was wrapped with black tape in those areas of the reels assembly. I think they added it there as an extra layer of protection agains chaffing. It’s just like the area where the wire bends from the cabinet to the door when it opens and closes. Because under that tape the wiring was still wrapped with the string. I could open everyone of my machines and the would look the same.

A lot of the black tape was loose, falling off, so I will re-tape some of the pinch point areas as you described.  :applause:


 :nerd: Also, the wiring was butchered in some places and I needed to get all of the wires exposed to do the repairs.

 :Scratch-Head: The belly light was totally butchered, everything was hacked, black tape, exposed wires. I basically gutted everything out, re-wired everything. The starter holder wires were cut short, creating a short, and I soldered new ones in place, using all of the old parts as much as possible. I over built everything, I wanted to be able to repair anything without having to do major work.

The starters were burned out, I replaced them while still using the old vintage covers. :applause:

On the electrical outlet, I put it together somewhat like the factory, I have a switch/plug for it. I think this would be as close to accurate as much as possible. The original one has some god awful electrical plug, most likely an afterthought. This way everything looks good, clean, attractive not FUGLY.

I'm hoping everyone will learn something from this thread, its been interesting dismantling a slot machine down to the bare cabinet, then progress through the machine step by step until the electrical, FUBAR, "gremlins" are finally exercised out of the machine. Having some other people's help with it was great, finding the original electrical wiring diagram was a big kick to repairing the wiring, removing fire hazard wires, adding a ground on the steel shell for protection, finding new electrical connectors was great, and purchasing some good reference books that aren't useless, having a book with a author that has "hands on experience" of the slot machine is invaluable.


This slot machine is now worth more than $200.00 since its fully functional, and when I'm able to find the missing pieces, it will be an awesome slot machine!


I'm still not finished, I have a lot to work on sourcing parts, and I will post my progress as I go. I'm also collecting extra parts for the future if some part goes bad.

More of a labor of love than anything else, I hate to see old stuff like this get trashed, gutted or worse.
I thought this must be real was bad with all of the repairs done by someone who doesn't have a clue how to use a phillips screwdriver.


To work on this type of machine you need patient's, and I cant say it enough. This is not all that to understand figure out the issues and remove them. An example is the hopper, a bearing was upside down, the hopper wound not operate, this is simple to resolve unless you don't have the patience to analyze the problem, and never change manufacturers design it has worked for 40 years so something isn't broken don't fix it.


Another important thing is get the repair manuals, and the wiring diagram. I have six Bally manuals and all of them get used. One major tool is using the correct tool for the job, there are several phillips screwdriver sizes, use them all and don't mar up the heads. Every buggered up screw got replaced in this machine, nothing is left that is a hack job. The wiring harness doesn't need to be hacked on, there are Molex connectors, shrink tubing, plenty of options to repair without hacking up the  wiring. The wooden case can be repaired using the same color plugs for holes in the cabinet. Take it slow and methodical, don't go fast, don't power the machine until you have the machine ready, I personally unplugged all the Molex connectors and then with the machine powered up, I check each system looking at everything for issues.


This is how I approached the repairs on this machine, everyone has a different approach, this is what makes unique and knowledge is important on repairing this machine.


I hope that someone can  learn something from this topic on a 1090-22.  :wave:

I've got three parts.

The quarter chute is awesome, handle hub is great and the hopper baffle assembly are installed. Slicker than snot!


The one coin chute that came with the slot machine was different where the coin dropped, it was wider inside and the coins would stack up inside the chute. The replacement slide is perfect for the coins they dont jamb up, its GREAT.

Gordy and Jim sent me the parts.

After contacting another member, I learned that Bally put black electrical tape in certain places. When I was rebuilding the slot machine black tape was everywhere. A lot of it was dry, loose, covering up patched wiring, after I cleaned up the wiring harness from the gunk I studied many Bally slot machines locating the factory black wiring inside the slot machine. With the different slot machines I was able to determine where the black tape was located reproducing the placement of the black tape using a European black cloth tape that will stay put indefinitely.


The only thing left is to locate the hopper cover, a bracket for the meters on the reel assembly and I would like to try and locate reproduction paper labels for inside the slot machine.

As per other Bally slot machines, I've put the black tape back for strength and protection in certain parts of the slot machine. I've applied it thin, not ugly, and it is not for hiding wire problems.

I don't like black tape, for me, when I look at it, I think something is hidden under the tape like splices, and soldering. On this wiring when I covered it you can feel the wires and know there is nothing to hide.

I've had more problems with business selling slot machine parts. One business in Nevada was totally rude, bad mouthing their own company. Another one in California is run by someone who is really disorganized, I've contacted him three weeks ago, and he keeps making excuses, forgets about orders, can't find his pen. Another one in California was really rude, and told me he was to busy to take orders.

All three of them tell me that the two parts I'm looking for are not needed, and to forget them, I'm the shopper, I want something, they don't need to force their opinions upon me.

Here on the forum its quite different, the members are great, I got the information I needed to restore the slot machine, I've been   documenting the process, so others can also learn about slot machines. Quick pro quo, it works great everyone wins we all learn from the restoration experience with great future reference material.


I'm only without the meter bracket, and the hopper cover. If I can't source them, I will visit a metal shop and have them fabricate the parts, or I can fabricate them. It would take much longer if I did them. I'm trying to put this back to manufacturers specs, it's not about what is needed to restore the slot machine just to make it work, it's about being authentic. If I could find the paper tags to replace the missing ones it would be awesome.

I'm working on fine tuning this slot machine and I'm finding things as I go. The payout is fluctuating, one quarter, two quarters, so I started looking at some problem areas. Mind you its not much but small things can cause issues.


I have a high capacity hopper pay out mechanism, its a real problem child, whoever working on this was insane. I've gotten rid of their mistakes, I'm spending time on this pay out and just when you think its working good you find something that is no ones at fault but the pass of time. Over time the cushion for the zero stop has become like tar, and every time a reset occurs the stop moves a hair. So I installed a new plastic stop. I'm hoping that over time it wont crack the plastic stop, unlike the other stop was like putty cushing the stop.


I'm having to fine tune the stop, thats a pita!  :banghead:

Most people use a pencil eraser to replace those old black bumpers. You need something soft to absorb the impact of the spiral cam returning to zero after a high coin payout. You will find that if you don’t have a bumper you will break the spiral cam.

 :24:  If you think about restoring a slot machine, you really need psychiatric help.  :fryingpan: 


So why do we work on these slot machines? It's a skill that is really made for people who just are not right in the head. Take me for example, I spent hours, days, weeks, months on this slot machine, and figuring out the problems are something I enjoy, the harder the nut is to crack, the more I'm in my element. I have to admit it is a obsession, not only getting the slot machine to function, but getting all of the bugs worked out.
 :PiggyBum:  I'm just the type who just loves these puzzles, however I have to admit I need a break since its intense. I've come a long way since I first bought this slot machine, and I really pleased with it, however this "extra coin payout" is a tough problem to figure out.   :Scratch-Head:


So I've been working on the payout counter, I've found a extra one I'm using for parts, which helps a lot. This slot machine spent years in service from the evidence on the contacts, wear and tear. What I'm learning is the rubber they used in 1979, when they built the slot machine, turned to tar causing some issues.


Another helpful tool is the original Bally repair books I've found. That is the best tool to have working on the slot machine in getting things inside the slot machine aligned correctly.


On with the repairs: the stop was replaced, two of the switches were burnt toast, the ratchet was not resetting the wiper assembly back to zero, just to name a few issues.


Trust me this will drive you crazy if you don't keep focussed, and it makes things worse if you forget where your working at inside the slot machine. The worse thing that can happen, is having to go to the bathroom.

 :duh:

If you haven't had experience in working on a Slot machine, its really difficult to figure things out, the repair manuals helps out but you really need to study the movement of the part your working on just to get a grasp of how it works. Remember if you adjust one thing it will impact other parts of the machinery so be careful what you do, when the stop on this payout mechanism turned to tar it would cause the stop to constantly change. After I replaced the stop I had to spend hours trying to figure out the exact setting so it work correctly.

Actually it's really quite a challenge to work on and I enjoyed working on these types of problems . See I told you have to be crazy to work on slot machines. :24: 




Above all don't even start this if you can't keep a level head, especially when you don't figure out the problem at first, and it gets really intense. I always take breaks, drink coffee, relax and have fun. I never let this get me upset, it's just a puzzle and figuring out the solution which is the reward.

I just figured that out. I cleaned the whole unit thinking that it had something to do with the coin disbursement. Nope, it progresses the coin from one, two, three.

I had one here a few month back that would over pay. It turned out to be that the nylon stop on the motor  armature was worn so bad that it would not stop. It would skip allowing extra coins to be paid. The other nylon brake part was also worn. Ended up gutting a spare hopper for parts. This is where a set of extension cables come in handy.

I'm working on the coin acceptor, coin lockout coil, and the coin diverter.


 :yes: I found out the coin lockout coil was gutted out, so after foraging around I found the parts. After I assembled the coin lockout I noticed it would jamb coins, and after scratching my head I noticed a bend in one of the metal parts. This bend was creating a jamb, after I straightened it out everything worked great.


You know that these coin assembly have bends throughout the mechanism so finding out what is the problem takes hours of careful research, and the last thing I want to do is create more problems by screwing up the coin assembly.  :no:


I've got the coin lockout assembly working flawlessly, now the coin diverter is next, I ordered a new coil for a replacement, this one is not functioning.


The coin acceptor is worn, I have done some cleaning and removing some rust. Seems that its working better since I've cleaned it up and adjusted things.


I don't understand why people cut wires, bend parts, tweak switches, install things upside down, I'm getting the problems removed, it just is taking time to make sure I don't create new problems.

Resistor

Title: Re: Detailed Restoration of a Bally 1090
Post by: rokgpsman on May 01, 2018, 10:43:38 PM
One end of the resistor has a color band closest to the end, that's the end you start counting with. For the first two bands you write down their number, then the third band is the multiplier band. The physical size of the resistor is also important, it tells you the wattage (how much heat it can take).

Your resistor in the photo looks ok, what's wrong with it? Looks like maybe the colored bands are gray-red-red, which translates to 8 (gray)  2 (red)  x 100 (red),  8200 ohms (same as 8.2k ohms). But hard to tell colors on my monitor. As for the wattage it looks like a 1 or 2 watt resistor, measure the length and check the chart below.

It's gray red red gray, I tried to figure out the code but the numbers got confusing. I'm also unable to find one with the same colors for sale.

The 4th band is just the tolerance band. You can think of it as the precision band, how close the resistor will actually be to what the color code says it should be. Instead of gray I think that 4th band is silver, it will be either silver or gold or blank for the 4th band on a carbon resistor like this. For this purpose you can use either a gold or silver tolerance resistor. Gold is 5% exactness, silver is 10% exactness (tolerance/precision).

Carbon resistors can change values as they get older, typically they increase value because of moisture absorption. You can still find carbon resistors but nowadays resistors are mostly made of "metal film" type. They hold their value much better than carbon style ones. You can use a metal film resistor, just as long as it is the same 8200 ohms size and the same wattage.

Here's one for sale, but you might find a better deal elsewhere. Select "8200 ohms" in the pulldown menu.

Don’t get me wrong with what I’m typing, but you want the machine original... The new resistor will not look like that one. They are a lot smaller and may be a different color with the exception for the markings. Why Change it if it’s not broken??

Me thinks my old broken down multi meter must be DOA because it was not registering. I have to get my backup meter.


So a good one looks normal, a bad one looks like burnt toast. Thanks for the information.  :thank_you:


On to checking out the coil with my backup meter since the resistor doesn't look like burnt toast.  :duh:
The electronics like this resistor is confusing to me, otherwise I've got things under control.


I've got several bugs removed, I just take time and I will figure it out. This problem with the coin assembly was that some parts were missing, bent parts, wrong parts etc. Looking at the drawings, photos, I can determine what is right and what is FUBAR. Right now its working pretty good, however I suspect the coin diverter is not working.


Thats how I figured out the switch on the reels was tweaked and not working, by looking at photos from other reels I was able to straighten out the switch where it was operating correctly between the reel assembly and the pay out assembly. Before I had no line of communication between the two.




THANKS FOR PUTTING UP WITH ME.

I'm really trying to find parts for the slot machine however its not working. Some of the businesses that sell used parts for slot machines are really strange people. I've tried and tried to contact these businesses with only no calls returned, no email returned, and one business said they only take check or cash when the website states they take credit cards.

All the time I'm being professional, pleasant, and I am going to quit trying to get parts because I'm banging my head against a wall. I will fabricate the last two pieces if need be.
 :banghead:


 :applause:
Everyone that I've contacted here in the forum asking questions getting responses are really helpful, nice and they have sold me parts that has helped me out getting to my goal. I am grateful for your support and I'm going to continue to donate to a worthy forum that is keeping the old slot machines running.
 :applause:
I still have work to do on the slot machine, finding the gremlins that keep sending out a extra coin, however I have a lead thanks to the people that have given me  another problem to look at.
 :applause:
Hell, I started with a slot machine that didn't function, the lights didn't work, the reels didn't  spin, the hopper wasn't not working, the payout was stuck, fuses that didn't work, to a 99% functioning slot machine.
 :applause:


I'll post more findings as I find the gremlins in the slot machine and remove them.

 :Scratch-Head:
A issue came up, the slot machine quit midway in a payout.


First I looked at the fuses, all of them were fine, in fact none of the fuses have blown since I've completed the most of restoration. I still have a few things to finish up.

 :nerd:
Second, I checked the wiring, the coin micro switch was clicking when activated, I removed the hopper and checked out the wiring, something was a miss as when I put it back inside the slot machine it works fine now.


I didn't think the reels had anything to do with it since the machine quit while dispensing coins.


I know the "hopper" problem must be near the connection that plugs into the machine. If it occurs again I will look at it for some loose wiring, or a plug problem. I'm just wanting to give you some information on finding out the problem when something quits working. This problem occurred yesterday after a long day of work and I left it alone until today when I had a good night's sleep. I found the problem pretty quickly, a loose solder wire. 


 :duh:
I'm still working on fine tuning the 25¢ coin assembly on the door, some parts were missing, others were wrong for the 25¢ assembly, now after replacing some FUBAR parts, now it's functioning good but it's not perfect.

Title: Re: Detailed Restoration of a Bally 1090
Post by: David Walz on May 07, 2018, 12:06:28 PM

 :Top_Award:

This is what I found; a meter bracket assembly, the old meters are going into the trash. I will use new meters I've gotten on the internet, as they are NOS. Putting it together, it will become a complete unit that actually functions inside the reel assembly.

Sometimes you have to take what you can get, the bracket is from a older slot machine from the 1960's however its the same bracket used on the 1090. The buyer accepted my offer making this slot machine 90% complete, however that damn hopper cover is going to be difficult to source, a couple of the slot machine companies who have the hopper cover are totally unreliable.



 :banghead:
This was the long way around to finding parts;
First I couldn't get a company in California to ship me parts, they dragged their feet for two months with only excuses, broken promises of shipping, and no results.
Second, the parts company in Nevada was unprofessional to say the least.
Third was a company in California that was down right rude.

The hopper knife was bent up from some lunatic, those knives are not generic, I've learned that from reading on this forum. Well on eBay someone had a knife "lot" for sale and I bought them. I thought I saw one knife that looked like mine and when it arrived, it fit like a glove. One less problem inside the hopper to deal with, coins jamming.

Once someone tweaks those knives its not worth messing with, the hopper will be problematic, and finding a good one in my opinion is the only way to go to resolve the issue.

Another thing that helps me out on working on my slot machine is the different Bally slot machine manuals. Some may repeat themselves on some subjects, but every manual offers something new on repairing the slot machine.


All of the manuals, books that I've found have got some really good information about the slot machines. Like the meters on the reel assembly, thats where I figured that the bracket was similar on some of the other slot machine reels. when I learned about the meter bracket being standard on the reels, I expanded my search to other slot machine's and found one.

If you want a really good book this is the cats meow.

I've been reading this book and it has some great information inside of it. After reading this book, its more like a in depth slot machine manual on how to repair everything inside a slot machine, a how to find out whats wrong with the slot machine, it also has wiring diagrams, and a whole lot more good information.

It should read "SLOT MACHINE FOR DUMMIES" since its easy to read, and a lot of good photos on the slot machine parts. :rotfl:

Another finished project, the original belly glass had a chip in it, so I replaced it. I built a wooden cabinet that is holding the chipped glass inside, using the wood trim I've covered up the chip. Basically, I recycled it. :)


The slot machine is in the sunroom, it leads out into the Sun Glow greenhouse no steps just walk into the greenhouse. The sunroom is more of a Alaska room, with a old style feeling. I thought the slot machine would fit better in their than our main house where its more formal, our house is kinda like a museum.

Good job on the lighted sign box using the glass with the chipped edge. What did you do to light it on the inside, is it one of those short under-counter type fluorescent lights?

You probably have all the Bally EM manuals you want but do you know about this place that has manuals? Often they are photocopies of out of print manuals but sometimes that's a lot better than nothing at all.

Two plastic chingaderas on the upper cabinet relays are broken, I've located a set of pinball relays to replace the plastic ones that are broken. I'm not going to disturb the contacts, coils, just replace the broken plastic.


If you are not up to date on sourcing parts, pinball machines are a great resource for acquiring parts. The coils are basically the same numbers. Some of the electrical component are useful, I purchased a "lot" from England of old arcade parts. Those parts were great for switches, wire, wire cover, coin slug, springs, and more.

I just got a call from a "reputable" slot machine company, they have a complete motor assembly NOS. This way if the old break on the hopper motor is not working 100% it should clear up the issue of the extra coins on a payout, besides the old motor I have was made in 1977, with that amount of wear it's probably on its last leg.

Thanks for your support it was not all that financially bad.

It's all about restoring this slot machine, I just can't purchase a fully functioning 100% slot machine shipped to Alaska at a reasonable cost. Shipping 400 pounds is not cost effectiveeffective, and besides they would be missing factory parts that were installed. :)


So I have to restore a slot machine up here in Alaska, and since Bally is a great slot machine, easy to work on, it was a no brainer. Once the missing parts are sourced, the slot machine will be restored completely, after that maintaining the slot machine from then on will be easy.

Meters are now installed inside the slot machine.


 :hissyfit: The person who removed the meters originally cut the wires real short, seems they did a lot of that on this slot machine, cutting wires short. Most of the time I've had to rewire to resolve the issue.

I installed a Molex plug to remedy this problem, if not, I would have to go and rewire the reel assembly. I found this bracket in a old 1960's Bally slot machine, so remember, you need to think outside of the box for slot machine parts.

As I said, think outside the box, this is the reel assembly I found the meter bracket, its old, but it works.


I spent sever hours looking for this bracket, it sure would be a whole lot easier to order on some slot machine parts website, however its impossible to work with some of those companies and slot machine parts are few and far inbetween. Once completed, it's just a matter of keeping the slot machine serviced with parts like coils and switches which are plentiful.

 :applause: Meters are installed, thats the good news, bad news the out meter is not working.
 :Scratch-Head:
Having a crap load of wiring drawings from several Bally books I determined the hopper was the issue. Sure enough the wire was MIA, so I had a game plan all ready worked out, the issue was to find a hopper set up arm switch that matched the wiring diagram. After checking the circuit out I found one that was isolated, and the wire 63-2 was the common wire, when a activated the 53-2 meter wire connects with 31-2 pulse wire closing the circuit to the 60-1 wire.

 :banghead: On another note, while I had the hopper out for repairs I found a wire that was soldered but not to the switch post, it was flopping around inside of the switch, with a plastic cover. This is a major issue since its on the hopper pulse, that can create interruption in the circuit. Thats why the hopper quit on one occasion, so I soldered it down.


I think this particular wire flopping around could cause erratic behavior, time will tell, it has to be soldered in place no matter what.




This has been one hell of an education on slot machine repairs, and I'm not sure, however I think I'm getting the hang of it now finding problems (created by a retard who worked on it before me) and solving the issue.  :24:

That service candle light you have there is for the earlier EM that didn't have the door hinge switch, like the 700 and 800 series slots. They were just a single bulb candle. Your game should have the dual bulb lights. White light signals the doors open and worked off the lower hinge switch. The colored lens was the service button found on the front door bezel. The dual lights are a diamond shape. Where yours the early style are square. See my pic. The different color lens was for different denomination of machines. Yellow, Red, Blue, Green, but I don’t remember what color was for what denom.. It was easier to look for a light color then walking around say for a nickel or 50c machine. Just look at the lights.

I was checking out the call switch, it was stuck. The switch has grease that is like a rock. Ive tried to clean it without much luck. I'm going to try and locate one online through a electronics place. It has six leads coming out of the switch, it actually is a on off switch from the Bally factory.


So I figured out how the light stays on this machine, this tower light has two bulbs, the call light flashes.  :applause:

I found another Bally slot machine switch. :)


 Thanks for the advice, I really, really, tried to clean it, its obvious that switch stopped being used a long time ago. I'm thinking that this machine has not been operational for awhile. The tower light works for service and jackpot, which I had to research the wiring diagram to locate the missing wires. Everything is going smoothly regarding restoring things, like the meters, missing wires, restoring things that have been cut out a long time ago.


I don't know what I would have done without a wiring schematic, that saved a lot of my work searching for wire locations, making the restoration easier on this slot machine.

PARTS CAME IN!

Hopper cover
Hopper chingaderas
Motor for hopper
Switch parts for the upper cabinet


Life is very good, sometimes you need to cattle prod people in a nice way to get them to move. It took 2 months but I got my hopper cover, at least they were not "unprofessional", just slow as snail s**t.

 :yes: In my opinion, I don't think it's about what the slot machine can do "without", its about this vintage slot machine being period correct for 1970's. Everything need to be in place, everything needs to be void of butchered wires, screws, holes that need to be filled, the cabinet needs to be repaired, some of the glass needs to be replaced with glass cfree from damage.
 :drool04:
A slot machine, just like any other machine needs everything, if you had a classic Ford missing the air cleaner, spare tire, shift knob, sure it will run fine, but it's much nicer having all of the parts making it more valuable than one that's missing parts.

 :rotfl: I'm way to much ocd, I need some professional help . :24: 


After I installed the hopper motor, the motor runs a whole lot faster than the old one, in fact it shoots quarters across the room. :RoadRunner1:

I've found a backup transformer, it was not all that expensive, less than $50.00. I'm stocking up on parts for the future. Makes life easier being so far away from a parts supplier in the lower 48.

Upper cabinet part of the progressive coin series, I'm working on the three coils and the assembly. The plastic is crumbling on the coils and the switch actuator.

What numbers I'm working with are two G-31-2000 and one G-33-2300. All three are crumbling.


So now I'm working on getting things replaced, and it's coming along. Right now, I have the armature and switches completed, on to the coils and thet don't look good.

More photos, the relay number on the broken one, G-33-2800 is different than the other two G-31-2000, I will have to verify it's correct since this machine has had been FUBAR before I purchased it, and I'm not taking any chances on getting it wrong.  :cool_thumb_up:


Talk about brittle, wow it just crumbles, (the plastic). This machine had seen some long term service.



 :applause:
Just found a photo on the forum from another member with a 1090 so I hope it's ok to post it. The coil is a G-33-2800, so I ordered one. Nice to know coils are plentiful and not obsolete. :)

I think its quite ironic, some of you are ripping out some parts that you consider "obsolete", and I'm re-installing the same parts back into the slot machine, wiring them up per factory.

 :fryingpan: Well, I think I've worn out my welcome here, I really really understand that I've asked so many different questions that I am having to quit asking, and just post my progress. The help you provided has been a great help in restoring the slot machine, I guess a lot of you didn't know just how far I was going on this restoration, which is all of the way.  :EmoticonHelp4:


 :thank_you:
Every member here that has posted on my questions, inquiry, etc. have been very helpful getting over the slot machine blockades I've encountered. That's really great having people who are knowable.


 :garfield:
One  goal was to get it overhauled, cleaned, serviced.
Another goal is to work on parts that were needing a good overhaul.
Another goal is to locate ALL of the factory slot machine parts and get them working correctly.
Another goal is to replace parts that are damaged from age like the plastic relay parts, switches for the call to service, stuff like that.

Finally achieving the ultimate goal, having a fully functional, fully operational, slot machine that is correct as much as possible.

Some people may think I'm just throwing time and money away trying to achieve my goal and I should just be happy I've got a slot machine that works, however it's not in my overall plans, I'm not modifying this slot machine, I'm restoring back to the factory when it was made in 1979.

Greetings,

I'm very new here, sometime in the 90's I was active on this board, which I think the site address has changed but same great people at New Life Games.  I have a 1973 Bally "Play Haves" machine that still works beautifully, but now not paying on large combinations, BAR & BELLS on up.  I like your machine, but I'm definitely starting green here with the proper posting and so on.  I know there are folks out here that still have a great love working on and playing these old electromechanical slots.  I wish you great success with your restoration.  :waving_flag:

These forum guys are cool, I'm talking about the ones that have posted on my pages, since I'm new here and I don't know everyone on the forum. The interaction with them has been positive, helpful, and they point you in the right direction.


 :banghead:
Outside the form, contacting some business selling slot machine parts has been disappointing trying to just get them to answer emails, answer the phone in a professional manor, and just send parts. It took me two months just to get a order sent to me from one business, another was unprofessional, one business I called had children screaming in the background, and one business was just rude.


 :cool_thumb_up:
Searching the internet, sometimes outside the United States can produce results, eBay has some parts, sometimes it pays to contact a seller and ask them if they have parts you are looking for, I've had forum members here sell me parts which was really great.

We are going to have speed bumps when dealing with something like electrical mechanical machines, knowing that parts are difficult to source, especially when they are 40+- years old.

Being a novice here I need to have all the help I can get. When dissembling a slot machine like mine you can get lost with the wiring harness. Having something like cue cards helps from getting lost in the rats nest of wiring. Since the Molex connectors are similar, you can plug them incorrectly unless you study the wiring attached to the connectors. A simple technique for me is temp tags that can be removed at anytime. I know that it's not a Bally feature, however when your eyeballs are full of wires the tags are great to use.
Title: Re: Detailed Restoration of a Bally 1090
Post by: David Walz on May 20, 2018, 11:20:59 AM
The meters are complete, I've found the" in decal" on another meter and glued it on to the meter missing one. The meters wires from the slot machine reels were cut short, I didn't want to make it ugly by splicing which is a big FUBAR. So I put a Molex connector and that will take care of the whole issue. It's amazing that wires are cut and left to short other things out in the slot machine. Tying them down to the reel frame keeps the wiring from getting tangled with the reel assembly, and the cabinet.
 :nerd:

If you see the label " swing up" refers to the reel lock. The reel locks were coming down when I first got them and I realized immediately that they were wrong, which were allowing the reels to migrate back and forth.

The picture is of the florescent light assembly for the upper reel light. The picture is of the door switch that I reset back to factory, it was bent preventing the door switch from operating properly. The door switch is factory, the florescent parts were butchered. The picture is of the handle release, the wiring is complete, also the reset button is original.


Like I said I'm a novice so having cue cards that are easily removed is the way to go for me. They don't detract from the value of the slot machine.

I still think the hopper cover looks sweet. It's really not a burden having it installed, since the slot machine is not being used full time it should be fine, and the holes in the cover provide adequate filling for the quarters to be filled into the hopper.


 :drool04: You don't see that hopper cover every day do you.  :drool04:


 :Jump:
It was worth two months of "professionally" prodding the business representative and finally getting the hopper cover. This business representative was not rude, unprofessional (like some of the other companies who sell parts) the representative was in my opinion forgetful and he was a older person. Still he was polite and did deliver the cover..

First thing!!!
 :Top_Award: :Top_Award:



I just got the slot machine up and running, so I started checking the payouts, well the new hopper motor assembly did the trick. The payout are nat's ass on every payout. If you have been keeping up on my postings I've been having trouble with the payout spitting out extra quarters erratically. I just didn't go out and buy this motor, I first serviced everything that could cause a erratic payout behavior.






Thanks to the members who helped me here the problem is solved.

Second thing:


 :Scratch-Head: I just got the coil for the upper cabinet. And when the machine is turned on it energized, so I'm like WTF?  Well I started reading the wiring diagram and I discovered that when the hopper is full of coins its energized, when the hopper is empty it is de-energized. The coin diverter is where the power is sent to, when the hopper is full or empty. I tried this for awhile and that is what the switch does, it is controlled by the hopper micro switch.


 :yes: Now it makes sense why the old coil plastic was so brittle.

The parts I used to repair the relays in the upper cabinet were from a Bally pinball machine, the parts are the same except for the coils. The switches could be used to replaced the slot machine switches.


This one is just one example of just one part that I could cross parts from the pinball machine.

Those small issues are really a mind teaser. I found a wire touching another wire on the hopper. I could not find it since it was a hair strand of wire touching the other contact. The solder job was after factory, I fixed that little bi**h.


Just that small hair wire caused intermittent problems with the slot machine.

I believe I finally kicked it's ass.  :Tongue_Out:


I've been looking for a problem for two day's checking every switch, plug, you name it, until I finally found it. When you look at it it looks like its correct, however when you test the circuit their is no power. Both switch leads looked really good until I got a good look and saw some crap. After cleaning it the correct way, by the Bally repair manual the slot machine is finally working like it's suppose to, interesting, it was working excellent, until I re-installed the meters, topper, etc. All of which were plug in, after I re-installed the Molex connectors which was matching the wires, so maybe the switch went out at the same time. I don't know, go figure. After checking every wire, switch, plug, coil, you name it, its been completely dissected. And the pay out is exact on all of the meters.


I'm now waiting on a toggle switch, and a electric door lock and that should be it.  :applause:

Yes, however it was working fine after I changed out the plastic pieces, it just started acting up after I installed the meters, thats when I discovered crap between the contacts. I didn't want to clean the switches just replace the plastic, I was trying to be careful not to go Willy nilly on the switches. If you look at it it looks fine, up close you can see a problem. Just a good cleaning cured the problem. It could have been something that was introduced when I replaced the plastic, and migrated into the contact. A lot of crap came off of the coil I replaced, the plastic was like dust, etc.

Post by: David Walz on May 26, 2018, 08:22:33 AM
For all of the novice slot machine owners who want a be slot machine service technician, this is what I've learned:



Don't do a single thing until you get some bally books, write in the books it as you go, make notes to keep you on course. Circle switches, coils, whatever it takes to keep you organized, this way you will not get lost in this complex machine when you are rooting out issues. If you don't, you will be chasing your tail.

Sometimes having to restore the machine you have to re-do your work since I haven't got pictures of the original configuration, it's like being in the dark that magnifying these problems, another issue is having someone else modifying the machine without any idea what they are doing.

It's important to locate photos of other similar models of slot machines to assist you in restoring the one you are working on.

Think of a slot machine as a tree, with branches, if you don't have some way of identifying each branch you will get easily lost.

Before you get started, make sure you have the Molex plugs marked, as they can be switched causing you some problems. Several dual plugs, sitting side by side are located throughout the slot machine.

"I may not be correct, but I'm trying to get it correct."


Recap on what I did:

Title: Re: Detailed Restoration of a Bally 1090
Post by: David Walz on May 26, 2018, 08:25:29 AM
Some issues; motor problems, break not working, bearings upside down, cut wires, holes in cabinet, stuck parts. Everything has been resolved even the cabinet holes inside and outside.


Just a important note of interest:

The hopper payout unit was serviced cleaned, etc. When I hit the jackpot it stopped at 50 coins, what happened was I had the torsion spring wound to tight, after I relieved the spring pressure it ran flawlessly.


When it stopped at 50 coins, I shut the machine off, and I adjusted the spring, then I turned it back on and it dispersed a total of 100 coins. After the spring adjustment I checked out the machine, and the payouts were right on, 2 coins, 4 coins everything is fine. The dispersing of coins are right on, and resetting to zero is fine.

Post by: David Walz on May 26, 2018, 08:41:54 AM
Other problems were missing slot machine parts. Finding obsolete parts can be challenging to say the least. Remember, once the slot machine is operational, fully funchional, the only real issues with a EM is: fuses, bulbs, coils, switches, things that are easily sourced, maintaining the slot machine is much easier than trying to figure out what some bonehead did to screw up the slot machine. As the Bally books said the slot machine will run indefinitely, it was made like a tank, to last forever as long as you don't butcher the machine.


Just my opinion,I think problems occur when cutting out parts causes the machine to start having problems. Just my opinion.


Just my opinion. What really blows your socks off is when you open the slot machine and you see everything inside, no cut wires, no missing parts, no spliced wires, no wire connectors (the ones in lamps) holding the wires together. The two cabinets are a symmetrical, they are repaired, outside and inside, all of the holes have been filled, repaired, covered up, making the two cabinets look really clean, and they are good looking, you can put this slot machine anywhere in the house it is not an eye sore, it would even look good in a museum. Its a real awesome sight, and if you are a person who knows anything about slot machines, taking one look at the inside of this on you can immediately see the detailed work, everything in place, wires looking perfect, all of the screws are not buggering they are new. It's basically a Vincent van Gogh that was found and restored. Just my opinion.

You have to go exploring to finding missing wires, when the person removed the pulse wire from the hopper thet didn't cut it they removed it with a soldering gun making my job job very difficult. After a couple of hours I got the meters working correctly.  :nerd:

 :nerd: Don't focus in on "your" slot machine model for parts, you can find parts from other Bally slot machines, pinball machines something like that. Some of the meters, brackets, switch, chingaderas, other parts are from other Bally machines, like a  pinball machine, slot macine, other parts are from a European Bally parts machine lot.


You have to think outside the box, explore other options.  :applause:
No modifications were allowed, they had to fit or it would not work. :banghead:


Another note of intrest:
I finally found my Bally 1090 service manual from 1977. Now I will have the correct repair manual and not search through six manuals just to repair the slot machine in the future. "Bally Dollar Slot Machines Service Manual & Parts Catalog #5000" This is a great book, its the correct one for my slot machine, all of the: wiring diagrams, reels, cabinet, door, $1.00 hopper, nuts and bolts, everything matches up. WOW it's great! A little to late, but well worth having the correct book on hand.

After cleaning the grunge from the cabinet the transformation was unbelievable.

Well I got a package today from Amechanic , it was the electronic door lock.
 :snoopy4: :snoopy4: :snoopy4:
Everything in the slot machine is complete, nothing is missing, everything is wired up correctly, all of the parts, pieces, chingaderas, you name it, it is connected, it is working. The coin diverter, anti cheat switch, coin switches are working, the meters are functioning correctly, the coin count is exact on all of the meters, in and out of the slot machine.


 :wav: :wav: :wav:


Life is good, this slot machine is sexier than Nancy Sinatra in the 1960's. Well, maybe not the the 1960's, maybe today.

Air cylinders are my first thing in these old machines. The rubber cup seal turns to a sticky tar. I just remove the old seal and clean up the mess it makes, then I apply a very thin amount grease on the steel piston and assemble. Do not use a large amount of grease or you will have a mess inside the machine as it squirts out of the air hole on the back of the air cylinder. Learned that the hard way.

Air cylinder grease/seal question.  Seems I have this exact problem.  Machine I recently obtained (mechanically sound and seemed well maintained) ran well for a few thousand coins, then handle got 'sticky' on the return.  Black sticky mess at the piston/cylinder
- Is using the wrong kind of grease at fault for the seal failing?
- What kind of grease should be used?  (Ordinary bearing grease?)
Thanks!

You don’t want a thick sticky grease. I like to use the blue grease that’s used for trailers and other wheel bearing that go into water. DO NOT use a lot of grease inside the cylinder. A very thin amount is more then enough. Just remove what’s left of the cup seal and clean up the black sticky goo. The cup seal is not needed.

Thanks!  Good way to clean the goo from inside the cylinder?  Used GoofOff for the piston (and was still a chore) but am afraid that would be too harsh for the plastic cylinder.  Do you know what kind of plastic that is?

Be careful cleaning the cylinder, I got grease shooting everywhere by accident.

 :cateyes:
Just my opinion:


With my parts being so old, and not knowing what would happen if I put any type of cleaner on them, I cleaned all of the plastic by hand.
It would be difficult to source some of the plastic parts if they melted. Better safe than sorry.


Also, the slot machine that I restored is running EXCELLENT.

I have found the rubbing alcohol works great for cleaning the air cylinders and pistons. A lot of paper towel and a pair of gloves come in handy to keep your hands clean. I’ve also used acetone solvent.

3M makes a citrus-based adhesive remover that worked awesome!  Rinsed immediately in case it is corrosive to the metal or plastic.  Think I DO need the seal tho, too much blow by, serves no purpose now.

The seal is obsolete, I looked everywhere for a replacement with no such luck. :(

I had found one that is close.  The ID is smaller and needs to be cut. Works OK but, not like the original. The only purpose of the seal is to keep the handle from slamming back into position. If you keep your hand on the handle during return it's not that much of an issue.


 Best just to clean it and lube it.


 I have thought that the next game I may try putting the piston on the lathe and cut a groove for an O-ring or two.  :Scratch-Head:

People have bought wheel cylinder cup seals and then had to cut the center out. In my opinion they are not needed. I just hold onto the handle till it’s back into the starting position.

Sometimes you have to try different things, brainstorming is a excellent tool, we see different ways to solve the problem. Sometimes I spend hours just trying to figure something out, other times its a snap. That's what's most important having the ability to focus on something and not go bananas.
