   Checking clutch plate 

3. Check friction lining (1a) of clutch plate on entry and exit sides for oil fouling, cracks and chipping.
4. Check thickness of friction lining.
5. Check damping springs (1b) for fractures and firm seating.
6. Check spline shaft profile (1c) for wear and chipping. It must be possible to slide the clutch plate on the transmission input shaft with little effort.
