[QUOTE="clevtrev, post: 27956, member: 187"] If the sprocket has been rubbing the case, that will tell you that the output bearing has moved inboard. The shim that you have that is mashed up goes between the input bearing and the fixed gear on the mainshaft. There should be no endfloat on the mainshaft, because the output shaft is pulled up to the drive side case, and the clutch shaft is pulled up to the G2 cover bearing. Your mashed up shim would have come from the clutch nut working loose, and allowing the shaft to float, what happens then , is that the shaft then hits the output shaft. [/QUOTE]
