Quoted from Playdium:With regards to the bat plunger, it might be helpful if you confirm the coil number. The plunger that I mentioned, #2A-2587 fits coil number H23-870 with a brass sleeve.
I have not had the time to add that. I had not realized that there could be an issue until I added the larger coil used In games mean’t for the plastic bat not a metal bat in a 58 Short Stop. The early plunger would stick in the brass sleeve. However, I was able to sand it a tad down and it fits well now. Williams were always tinkering with the games you can see this in the schematics year by year. It was a dynamic time in their R&d dept for sure getting the best out of these games.
I know I am tinkering with the originality but this is reversible and the less powerful coil is stowed in the back of the game. I am not sure how the games worked when the mech’s were not worn. There was a nylon washer at the interface of the cam and the pitching assembly that was there to reduce friction on the Short Stop So that said I was trying to get more power and zip to this game which I achieved to a point. In this game I seem to be unable to get another 1/2 turn to the pitching cam spring to fire that ball really fast like my other games.
Referencing Williams R&D tinkering, one of my games cam lever has 2 spring stop screw holes that permits another 1/2 turn or more than The other games. The speed from the fast ball is so fast it can be unhittable. I had to readjust to take some power off.
I will review the Williams parts books and see how much I can add to the tables.
