6. Check the condition of the springs and the conical notches of the splines of the driven disk. The diameter of the driven disk is the same on all engines (see illustration).
2.6 Clutch installed on engines with MLT5 gearbox
1 - driven clutch disc
2 - mounting pin
3 - pressure plate
4 - clutch release bearing
7. Replace the driven disc if the friction linings are oily. They cannot be cleaned.
8. Check the thickness of the friction linings and the condition of the pressure plate (see illustration).
2.8 Check the thickness of the friction linings of the driven disc using a caliper
If the remaining thickness of the linings is less than 0.30 mm, the driven disc should be replaced. The disc whose residual thickness of the friction linings is slightly greater than the specified size must also be replaced.
9. Check the runout of the driven disk by slowly turning it and watching the indicator arrow. If the indicator reading is only slightly higher than 0.8 mm, the disc can be straightened with some care. Otherwise, it must be replaced (see illustration).
2.9 Check the runout of the driven disk by slowly turning it and watching the indicator arrow
10. Check the condition of the driven disk splines. If they are broken, the disk must be replaced (see illustration).
2.10 Check the condition of the driven disk splines. If they are broken, the disk must be replaced
11. Check the pressure plate for warping or deformation. Place a steel ruler on the working surface of the disc and measure the gap using a template. If the gap height is greater than 0.3 mm, the pressure plate should be replaced (see illustration).
2.11 Check the pressure plate for warping and deformation. Place a steel ruler on the working surface of the disc and measure the gap with a template
12. Check the flywheel runout by attaching a dial indicator as shown in the illustration and rotating the flywheel. The flywheel runout should not exceed 0.10 mm (see illustration).
2.12 Check the flywheel runout by attaching a dial indicator as shown in the illustration and rotating the flywheel
If it is necessary to remove the flywheel from the crankshaft, then when it is subsequently installed, the old mounting bolts should be replaced with new ones. Tighten the bolts in a crisscross pattern. Before installing the flywheel, clean the flywheel surface on the crankshaft side, as well as the shaft mounting surface.
