Hi. I have a 1964 Bally "Happy Tour" (nearly identical to the "Grand Tour") with a broken "tens" scoring reel. I'm fairly handy and am going to try to fix this myself, and I'm comfortable working inside the machine (but I don't know all of the correct terminology, so please correct me).
The symptoms were the "tens" scoring reel wouldn't move and would buzz when activated. Upon removing the scoring reel, i could see that the plastic armature (?) that connects to the coil solenoid was broken off and missing, as was the plunger (?) from the coil. See picture 1 & 2. This was a mystery as I could find neither piece on the floor of the pinball machine or anywhere. Upon removing the coil from the reel and looking inside, however, I could see that both the plunger and the broken off piece were inside the coil and stuck solid. See picture 3.
So it's clear to me that I need to replace the coil and the armature.
1. What is the Armature actually called so I can look for the right part?
2. The coil is too darkened to read any numbers on it. The coils on the "ones" and "tens" reels are much newer and I can read the numbers, but the numbers are different. Is it possible that the different scoring reels would use different coils? or does the number vary? See picture 4 & 5 . What coil should I be buying?
3. It looks like the wire in the working scoring reel with the blue-wrapped coil is loose. Should I be replacing that one while I'm at it?
4. Finally, I'm not sure exactly how to clean and lubricate the whole mechanism. Any advice?
Thanks for indulging all of my questions and correcting any words I've gotten wrong!
