For about the last week I’ve been doing the steppers and the score reel cleanups/repairs in the back box. Actually I’d been going back n forth between this game’s backglass, the backbox mechanics rebuild and Cam’s (big dog)’s Meteor that I’m repairing for him.

These few pics are of the player unit in the backbox, which was in dire need of a rebuild. First thing I did was remove the wiper disc and soak it in Prepsol overnight to remove any oil and grease in the contact pins. While the stepper disc was soaking dismantled/cleaned and rebuilt the rest of the player units mechanics.

Notice the crappy looking collapsed springs on the wiper unit in the 2nd pic. I had to replace these with new springs, some of them are already done in this pic(the narrower springs in the pics are replacement springs I used). The originals that were still in good shape were left alone. In order to remove the pins and springs I had to grind off the flattened ends of each pin (that holds them in place) to remove them. On each pair of pins I soldered a piece of wire to help get a better electrical contact between each pair (rather than rely on the contact between the pins, their bushings and the printed track on the disc), and the wire/solder doubles to keep the pins in place! (3rd pic).

Last pic is the player unit rebuilt. At the moment im half way through doing the score reels, i've had a couple of small issues to deal with in this area, and I came up with a couple of unusual but effective fixes that I’ll detail in the next update!!
