I'll start off by saying I'm a clutch rookie. Anyways while replacing the belt, i reinstalled the primary and engaged the clutch to make sure everything was the same. Something wrong with the primary and upon disassembly, one of the weights had broken and several others were flat spotted. I'm sure the weight moved during removal and broke during the test run, even though I didn't go above half throttle. But is clutch weight wear common even with ample grease? Never had mud or water in the clutch area or never slipped a belt. 07 700 with about 9000km and almost all with tracks.
