Hi - new to the forum and need some advice. My arctic cat has been extremely reliable until recently when the primary clutch nut backed off. I ordered and replaced the nut and then it began slipping under load. I thought the belt might need to be replaced so I put in a new Dayco belt this evening. Now there seems to be a grinding noise between the stationary drive sheave and the drive face shroud. There are 3 spots along the circle that have rubbed enough to produce metal shavings. I would appreciate your thought about what I need to replace next.
