Disc

- Inspect splines. Clutch discs must slide easily on short drive shaft. Slight radial play is designed in and is not important.
- Inspect rivets. Replace clutch disc when in doubt.
- Inspect clutch linings. If clutch linings are covered with oil, burnt, damaged or worn locally, install a new clutch discs.
- Check lining thickness of clutch discs. Measure distance from lining to highest point (rivet) on all four linings. Replace clutch discs when less than 0.3 mm.

NOTE: Since clutch discs will be subject to different degrees of wear in operation, the lining thickness will vary. On the unsprung disc the flywheel end lining between the flywheel and intermediate plate (white dot of paint) will be considerably thinner.

- Check clutch discs with lining for lateral runout. Max. permissible lateral runout at 190 mm diameter: 0.4 mm.
