One of the 8 pointed sprockets broke in half the other day on my machine. These are the sprockets that help turn the rollers and are connected on each side by a small (bicycle type) chain. They seem to be held onto the roller shaft by a flat type of cotter pin. Anyone ever tried to replace this before or is this a take it into the shop kinda fix?
Seems the chain is kind hard to take off and woudl be hard to put back on.
Any thoughts would be appreciated?
