Went looking for a 742 and came home with a 891-1. Needs a cleaning a some adustments. Parts complete. 1st on list though is good reel snap. Pull handle down and its like it needs a little more travel to start reels spinning. So I guess I will be starting on right side of reel mech. Also need to learn how credit meter works. Has both hopper and credit meter.

Jim... I would clean the air cylinder first before making too many adjustments.. I have had them so dirty that the cylinder had a hard time making a full travel.. Next check the roll pin on the back shaft crank linkage.. Far lower back right side.. I have a 4 reel E Series that the hole in the shaft is worn egg shaped causing that machine to not want to crank every once in a while.. I'm thinking of drilling it out over size and going to the next larger size roll pin available..

Thanks Gary, pulled cylinder after reading your post. Yep, it was a mess. Machine sat for "years".

What I am waiting to test is credit system. If I turn lower key 180 degrees, bottom right reel glass lights up saying "push button to play credits". I just need to find out how to accumulate credits.

Thanks Gary.

I think what that means is that you get paid in credits instead of coins. Setup a jackpot on the machine and see it if gives you credits instead of coins.

Well got reels spinning. Few bugs nothing terrible. Short pays on multi coins. Hopper not reseting fully for paying more than one coin. I like the x's units better than follower. 7's the hopper runs hopper empty if I let it. Going to clean and check spring tension.

I had the upper switch "on", which i believe runs meter down. I am guessing right now thats why it paid from hopper no matter what position bottom switch was in.

Tomorrow I'll play some more.

Shortpaying and hopper runs dry problems are probably both on the payout disc - clean it to make it reset and chek that it can step the jackpot manually

Happy hunting

Jim take this to someone that can print blueprints get it laminated so you can draw on it and it should help with the credit meter and understanding that circuit

Thanks Denmark. I will give the hopper payout disc a careful cleaning.

Jon, Thank you very much for the PDF. I really appreciate it. It should be a huge help. Probably to take file to Kinko's, they have large printers I saw when having normal copies made. Thanks Jon.

Holy crap. Talk about making things complicated. I am not a fan of the odds follower and cam motors. Crazy schematic. The x units are a breeze compared to this system. I understand that on multiple coin pays, it pays one coins worth then resets hopper and pays the next coin played worth but trying to follow on schematic is going to take awhile.
Cleaned contacts on paydisk and added tension to spring so it resets to zero before paying next coin. Got a little work to do on jackpot pays.
Still looking into credit system.

Now you know why I said to laminate it use a grease pencil to trace the circuits it is one complicated machine I have 10 different color grease pencils to trace circuits on some machines

I am a fan of the credit meter since restoring my bingo machine which is basiclay a continental
the switch at the bottom switches between cash and credit play the key in the center has to be in the right position its used to run down the credit meter you can tell if its in the wrong position as the score motor runs constantly
you should be able to play with coins when in the credit position, the coins are diverted from the hopper but all wins register to the meter or if you have credits you can turn the bottom switch to cash play and then use the credits left on the meter then any wins will be payed in cash I was surprised by how fast you can play the machine when using the button just hold it in and it soon racks up 6 coins
deepest apologies was recalling from memory no there is only 1 coil
in cash it works as an ordinary hopper where the coin under the arm drives the payout
(I`m guessing a bit here cause I cant remember)in credit mode the hopper motor is switched out and the coil is then controlled by the score motor and odds disc its easier to see on a larger payout the payout counter on the hopper starts to count but is reset by the score motor and starts again what I have not quite understood is the relationship when you have a x1 pay you will get 12 pulses from the score motor x2 is 6 pulses and x6 is 2 pulses because I`m not sure what all the pulses are doing I did make some notes but they don't make sense to me now (bit like this post of mine)

Mark could you send a pic of the two solenoids behind pay board. when you say payboard are you talking payout disc on hopper OR below credit meter behind the top board behind the top awards glass?

When I turn the bottom key to play or accumulate credits, if i hit a winner the hopper doesnt turn on (which is what i expect) the solenoid on hopper behind payout disc does count up moving wiper fingers. Multiple coin winner it resets and pays (counts) for each coin played. But the credit meter doesnt advance stays at zero on meter. Hoping just dirty connector in that circuit.

Thanks.

Jim, is that one coil good? That paper wrap looks black like its been hot..

Gary

jimliner · « **Reply #13 on:** September 19, 2016, 02:51:33 PM »

Hi Gary,

I think its oil or grease that dripped down from above. Currently it works the reset levers to zero wipers. I will wipe off next time I open it up.

Bottom key - banks of switches.

Amechanic · « **Reply #15 on:** September 19, 2016, 03:00:21 PM »

That's a lot of switches....

jim have edited my last post

Cheers Mark. Thanks. I was a bit worried it might be missing something. I will probably have a few more question in the coming weeks.
Thanks,
Jim

Wich one is the "air cylinder"? Pics?

jimliner · « **Reply #19 on:** September 21, 2016, 07:44:10 PM »

Right side of reel mech. Typically tan/brown tube cylinder mounted horizontal about 6 inches long. I'll post pic next I have reel mech out.
