It seems to be running perfectly, other than it looks as though someone cut a bell wire. I need to pull reels for access, and am not sure how or if I can do it without any readjustment.

It's fairly common for people to cut the bell wire as it's really too loud in a home setting.  I just packed and stuffed foam against the bell to greatly reduce the racket. 

As far as reel mech goes, there are two levers (one on each side of the lower front of the reel frame.  You pull both forward and down so they unlatch from the shelf and then just pull on the whole assembly to slide it out of the machine.  This will require no re-adjustment of any kind.  One lever is shown at about the 0:45 second mark of this video:https://www.youtube.com/watch?v=uaafBYf4eck.

As it is working, if you still have questions, I'd suggest you request a moderator to move this thread to the Bally EM forum or mark this one closed and start a new thread in that forum.

Drill out the rivets, clean and paint. Use aluminum rivets when reinstalling

I all ready removed the plastic from the steel plate. 

I have a plethora of tools, and I appreciate your input. 

i had a working S2000 .25 slot machine this morning. I received a new Gen2 printer today and tested in my working S2000 machine. I took to my new slot and added it and thought it may work because a printer was installed at 1 time a while back. I hot cash out and the issues started. my frist error was call attendant hopper empty. I went thought the options in setting #3 and found nothing. I purchased a key chip recently (17 and 97) installed on the board and nothing happened. I put the game chip back and when it boots up it now say call attendant i hot the reset button a few times and it now says game type mismatch. Things i noticed. during bootup it was showing 1 cent as denom and acting like a multi denom machine. I was able to get to the options menu but it only gives me options 1 2 and 4. no number 3 game options. Am i using the correct key chip for this board. I cant find the model but it looks like a 1952XXX board. I am not sure if i can post youtube link but if its not barred please check the link below.

I also have 2 other 1952-2 and 1952-0 boards is it alright if i swap the chips to this other board?

So that would be a cc-33 not a cc-16

If you want to use quarters you will also need to look at the hopper too.
It would have a large wheel for dollar ls vs one designed for quarters.

No hopper I need to pick one up later on.
