Checking Clutch After Dismantling

TO CHECK THE CLUTCH AFTER DISMANTLING AND TO CHANGE THE CLUTCH PLATE LINING
1. Check the contact surface of the clutch plate on the flywheel. If the surface is "blued" and has hairline cracks, this is of minor importance. But if the surface is deeply scratched, the flywheel should be turned or a new flywheel should be fitted.
2. Check the pressure plate for scratches and misalignment, and check the diaphragm spring for wear at the contact surface with the release bearing. If the pressure plate or diaphragm spring is defective, fit a new pressure plate unit.
3. Check the release bearing for noise, wear or other defects.
4. Check the clutch plate for wear and fit a new clutch plate, if necessary.

NOTES:
- Checks on a new clutch plate:
^ When the clutch plate is subjected to a load of 4230 N (948 Ib) between two parallel surfaces, its thickness should be 7.11 - 7.62 mm (0.28 - 0.30 in) or 6.86 - 7.37 mm (0.27 - 0.29 in) on a Turbo clutch plate.
^ The clutch plate should be completely free when the surfaces have been moved apart by 1.27 mm (0.05 in) from the position they had when the above load was applied.
- The flywheel is secured with bolts which have a low head, to provide space for the clutch plate damper. When fitting new bolts, make sure that the right type of bolt is used.
