I am getting ready to rebuild all 8 of the score reels on my 1974 Gottlieb Duotron machine. There are a couple sluggish one on the 1st player and most hang up on the second. I'd like to go through them so I can put the back cover back on and move the machine against the wall without having to worry about the scoring for a while.
I bought 8 spring kits from PB resource and new sleeves. I plan on carefully disassembling each score reel, cleaning all the parts, the install the new sleeves and fresh springs. I've read that some people put a thin coating of super lube grease on the PCB for each reel. Is that the best practice? Also, are there any other parts which should be lubricated? I have both the super lube teflon grease and the lighter super lube oil.
Or, should it all be put back together completely dry with no lubrication?
I'd like to do this right the first time so I won't have to mess around with them again for a while.
