Great product

Clutch chipped very easily with normal use. Left overnight and rusting started immediately. Clutch also produces extreme heat when barely used for 3 minutes. So hot it could boil an egg. Would not recommend.

It has already gone bad. I just found pieces of the clutch have broken and fell out Started knocking shortly after installation but functioned correctly. Probably from Revolution Clutches Theirs did the knocking and burned up. Not heavy use of sawmill1 log per day or so 150 to 200 ftmax
