Thanks for all of the work you are doing and documenting here!
I have been working on an On Beam that is having reset bank issues. Sometimes the motor pauses before a full rotation and sometimes the motor spins but the cams don’t move.
I am totally lost on how this device is put together and how it works. I would love to see a video of it being disassembled/reassembled and the inner workings explained.
Quoted from DCP:Great pics, emspence ! PM'd you about the cams I'm sending to you also.
This is the first time I have seen the clutch in another machine. It looks identical - now we need to find a Pinsider with a lathe who would like to turn some simple steel parts for us. I may put out a call on a new thread for that - I have drawings and a CAD model of the two steel clutch parts already. I've never been able to find a spring clutch that exact size in any mechanical parts catalogs. It may have been custom-made for Bally.
New steel clutch, new springs, and new cams would make a nice "rebuild kit" for a lot of these cam-reset Ballys. I'd better get on it!
I would be in for one!
Quoted from DCP:The critical dimension of the spring is the inside diameter 0.620". It is wound from .040" music wire, also known as 17.5 gauge wire. The spring would need to be wound onto a 0.495" diameter mandrel (bar) for it to spring back to 0.620.
I'll have to dig around to find the rest of the dimensions, or I'll just remeasure it.
We need to get those springs made!!! Those seem to be more of a problem than the plastic clutch parts themselves.

Yes please!
