Recommendation. When replacing the clutch disc, it is advisable to replace the pressure plate as well (basket), even if there are no visible signs of wear on its working surface. The fact is that during operation its working surface wears out and the rigidity of the diaphragm spring weakens. It is also necessary to replace the release bearing if it has play, sticks during rotation or makes a clearly audible noise (see above, «Checking the technical condition of the clutch»).
To do the job, you will need a mandrel to center the clutch disc.
Comment. The work is shown on an automated gearbox.
Removing
1. Remove the gearbox (see «Manual transmission - removal and installation» or «Automated transmission - removal and installation»).
Recommendation. If replacing the pressure plate assembly (baskets) not planned, we mark its position on the flywheel with a center punch.
2. Using an 8 mm socket or ring wrench, unscrew the six bolts securing the basket to the flywheel, holding the flywheel from turning with a mounting spatula or a large slotted screwdriver.
3. Remove the basket and driven disk.
4. Pulling towards you, remove the release bearing 1 from the guide sleeve. Remove the lever 2 from the crankcase hole together with the protective cover 3. Wash the removed parts in kerosene. We replace damaged and worn parts.
Installation
1. We clean the spline part of the input shaft of the gearbox and the guide sleeve of the release bearing from dirt and old grease.
2. We apply a thin layer of SHRUS-4 grease on them and on the working surface of the clutch fork axis.
3. Install drive parts in the clutch housing (fork, spring, release bearing) in the reverse order of removal Apply grease to the working surface of the fork.
4. We insert the centering mandrel into the hole in the end of the crankshaft.
5. We install the clutch driven disk on the mandrel, orienting it so that the side where the disk hub protrudes more is facing the gearbox.
6. Install the basket.
7. Aligning the previously made marks, use an 8 mm socket wrench to evenly tighten the basket fastening bolts. Finally tighten the bolts to a torque of 19.1-30.9 Nm (2.0-3.2 kgcm).
8. Remove the centering mandrel
9. Install the gearbox in the reverse order of removal.
10. We check the operation of the clutch release drive, if necessary, eliminate the detected malfunction.
