0Peter.Steele 8 years ago ReplyUpvote Is this the Petsafe litter box with the rotating litter tray and the conveyor that lifts the stuff and drops it into the bin? If that's the case, then your problem isn't (just) the motor. It's the fact that the idiots that make this box put a plastic gear in a location that is susceptible to getting litter in it, and then mated it to a metal gear on the driver motor. Basically what happens is that litter gets pulverzed and packed into the teerh of the plastic gear, and then the metal gear winds up stripping out the plastic teeth of the gear. Mine is stripped out. I'm going to wind up making a replacement gear out of - probably - JB weld to start with, until I get a milling machine set up.
