So I decided to cut open two broken vend motors out of a westinghouse select-o-matic machine. Both motor electrical components work but the gears wont turn.
I found the gear that strips
After he electric motor gear turns it contacts a bigger wooden type gear which if the vend motor has to struggle to work the vend mech or gets stuck will strip the gear.
I'm in the process of finding a plastic gear that can replace the broken one.
I plan to replace the gear and weld up the cuts made to get into the sealed gear box.
I hope it works out since these motors are hard to come by.
