2.7 Check the condition of the diaphragm spring (see arrows)
8. Check up fastening of a spring between a pressure disk and a cover and be convinced of absence of cracks. Make sure the rivets are firmly seated. Replace disc with damaged or loose rivets.
9. Check up a basic surface of a pressure plate on absence of cracks, burning and deterioration. Discs with an inward deflection of up to 0.3 mm can still be reinstalled. Check with a ruler and measuring template.
2.9 Check pressure plate bearing surface for cracks, scorching and wear
10. Check the condition of the flywheel. Make sure there are no burn marks or ripples. If engine oil leaks from under the crankshaft oil seal, the flywheel should be removed and the oil seal replaced. The new oil seal is stuffed with a suitable mandrel. After that, install the flywheel in place and secure with bolts, tightening them evenly with a force of 55 Nm.
11. Sand the mating surfaces of the pressure plate and flywheel with fine-grained sandpaper.
12. Replace oily or mechanically damaged clutch discs.
13. Check the thickness of the clutch disc friction lining with a vernier caliper. The permissible residual thickness E must be 8.3 mm. For cars with a 1.4-liter engine - 8.5 mm. If the residual thickness of the friction lining is less than the permissible one, then the disc must be replaced with a new one. The same applies if the friction lining is cracked (see illustration).
2.13 Check the thickness of the clutch disc friction lining with a vernier caliper. The permissible residual thickness E must be 8.3 mm.
14. Check the ease of movement of the release bearing. If necessary, replace the bearing with a new one.
