Hi all.
I’m pretty new to all of this so I’ll do my best to explain using my limited EM Vocabulary...
I picked up a 1955 Chicago Coin Shuffle Bowler in January. It’s my first EM machine (no experience with non-em either). I managed to get it working by cleaning a few stepper units, messing with the gap on a few switches etc and all was well until this weekend.
I believe I’ve narrowed down the issue but am stuck on how to address...
The ‘1st Shot’ switch on the reset bank (?) barely moves up and down. If I use my nail to push down on the disk with the catch below the rest (sorry, not sure what that’s called) they spring up smoothly and the game reacts. If I do so on the ‘1st Shot’ one, it doesn’t move at all.
I can trigger a back row switch under the pins and see that the disk drops down and disengages the catch, but that’s it. No springing up movement at all. This makes me think it’s friction vs electric?
I can manually slide it up and down but only with a fair amount of a grinding sound and a fair amount of resistance. Again, seems like friction?
The grinding is coming from the spot where 1” or so on each side slides through two small channels in the lower support bar.
With or without the spring, same behavior.
I have no idea how this changed. It did happen after I opened everything up to change out the rubber in the back and replace a pin, but beyond the cabinet getting knocked around a bit opening/closing I can’t see how that’d be related?
The disk with the catch does seem to have a bit more play than the others, but I don’t think that’s related since it sticks even when I manually unlatch it with my nail and it disengages when I trip the back row switch?
Before I started just trying to bend it blindly or try lube or something to get it to move, I figured I’d come here!
Is this something that happens commonly? Should I try bending? Some Teflon lube (or other) on the brass where it’s grinding? Some other adjustments (I couldn’t find anything that seemed ‘adjustable’).
I’ve included a few pictures in case any of them are useful.
Help?!?
Thanks in advance all!
