Originally posted by wiseman Did you replace the motor or just the gear? If just the gear, what keeps the gear from spinning on the motor shaft? By spinning I mean rotating independently from the motor shaft. Is there a flat on the motor shaft? Also, what secures the gear to the motor shaft?
I replaced just the gear, because my original intent was to do the repair using
CRM-114's less invasive method but that didn't work for me.
There is no flat spot on the shaft, and the gear fits by friction alone, but that really seems to be enough. The inside diameter of the gear is probably just a little smaller than the diameter of the shaft, and the gear material (
either plastic or brass) deforms just enough to allow you to press it on. It's a very snug fit. Of course that might also contribute to why it cracked in the first place.
