I’m experiencing a mechanical issue with my ‘59 Williams Pinch Hitter running man unit. The runners are attached to 4-armed wheel that rotates underneath the playfield. When these men are rotated up and running the bases, they close switches at 1st, 2nd, and 3rd base which, on my game, activates the “pinch hitter” feature. The problem is that the 4 arm wheel on my game has play on the shaft. Once the wheel stops and hits the wire arms, it backs off because of this slop in the fit. This makes adjusting the switches to get the correct full open and close at the correct positions very difficult. When I move the wheel back and forth (maybe 1/8”), none of the other components move with it. It’s free to move on the shaft. The brass collar pictured above it does not move with the wheel.
I am assuming this play is not normal and should be eliminated. If so, how is this wheel attached to the shaft? Is it keyed?
Any insights would be appreciated.
