I’m having issues with my changer not dispensing coins. I took it the hopper apart and it appears the red conveyor has worn down over time. Am I correct in assuming that the notches on the conveyor should fit nicely into the track? Mine appear to be extremely worn down. When I opened the hopper up the conveyor was not in the track. It had worked its way out. Can you purchase just the conveyor? I don’t see it on KR anywhere.
