06 rhino 660 machined clutch install
i installed the new sheave thatwas machined installed anew peerformance belt. put all back togethor and put the washer and nut on with a impact & test run it without the cover did fine. drove it and the nut backed off and messed the threads up on the shaft. so i got another shaft and installed it again making sure every thing was seated properly. & the cam in the clutch stripped & messed up the threads when i removed the nut from the shaft to look at the problem so got another shaft on the way idk what i'm doing wrong.anyone had this problem?
