Clutch disassembled: 1 - pressure plate; 2 - clutch housing; 3 - diaphragm spring; 4 - driven disk
Remove the gearbox (see subsection 12.2.).
Note 1: When loosening the clutch housing mounting bolts, lock the flywheel with a screwdriver. Install the bolt to support the screwdriver.
Note 2. The clutch can be removed without a mandrel, but you need to hold the driven disk - it can fall out of the clutch housing. The mandrel can be made according to the dimensions of the primary shaft or you can use the old primary shaft instead.
Flywheel friction working surface.
1. Insert a drift into the hole in the pressure plate and remove the six bolts securing the clutch housing to the flywheel (see notes 1 and 2).
2. Carefully remove the clutch housing with the driven disk.
3. Inspect the driven disk. There should be no cracks on the driven disk parts. Check the wear of the friction linings. Replace the friction linings or the driven disk in the following cases: a) the rivet heads are recessed by less than 0.2 mm; b) the surface of the friction linings is oily; c) the riveted joints are loose.

4. Check the reliability of the damper springs in the sockets of the driven disk hub. If the springs are broken, the disk must be replaced. If a visual inspection reveals warping of the disk, check its runout. If the runout value exceeds 0.5 mm, replace the disk.
5. Inspect the working friction surfaces of the flywheel and pressure plate: they should not have deep scratches, nicks, dents, obvious signs of wear and overheating. Loosening of the riveted joints of the pressure plate parts is unacceptable. If defects are found on the flywheel or pressure plate, we recommend replacing them.
6. Carefully inspect and evaluate the condition of the support rings and the diaphragm spring of the pressure plate. The support rings should not have cracks or signs of wear. The presence of cracks on the diaphragm spring is unacceptable. The contact points of the spring petals with the clutch release bearing should be in the same plane and have no obvious signs of wear.
7. Install the driven disc into the pressure plate housing so that the less protruding part of the hub is directed towards the flywheel.
8. Insert the centering mandrel into the splines of the driven disk from the diaphragm spring side.
9. Install the clutch on the flywheel and tighten the six clutch-to-flywheel mounting bolts evenly diagonally to a torque of 19-31 N·m (1.9-3.1 kgf·m). Then remove the centering mandrel.
