After owning my Davis VS2 for almost a year I finally put a new treadle belt on her today. The problem is that the treadle wheel is wobbly i.e. not turning true and is very noisy compared to my other treadles. I am trying to diagnose and fix the problem. Question. Is there a bushing of some sort that the wheel turns on? If I have to I will remove the wheel which I really don't want to do.
