The machine is jackpotting and also crushing cans. I have read several threads and I think it needs some motors replaced and some adjustments. I know the brake is broken on the #5 motor.
My real question is will this motor on ebay (Ed. note: link broken) work for the double columns and will this motor on ebay (Ed. note: link broken) work for the singles?

I have good used motors in stock for these if you'd like to get them from one source. I can sell them to you for $22 each. It would be a good idea if you could post a description of the "jackpotting" and "crushing cans" as to which columns do it and under what circumstances. There might be other reasons for your problems.
From what I can see in the photo of your machine, the motor on column 2 is missing the wide motor switch actuator arm and the motor on column 5 has a broken brake hook that won't stop your motor from coasting. Are these the columns you are referring to?
