If the clutch is slipping. then the friction discs are the usual culprit, along with weak pressure springs. We would suggest however, after careful examination of all the parts that make up the clutch assembly, any parts showing signs of wear or damage are replaced at the same time. It only needs the failure of one part to undo all the good work that has been done!
