Attention! When the clutch disc wears out, dust containing asbestos is formed, which is hazardous to your health. DO NOT remove dust with compressed air and DO NOT inhale it. DO NOT use gasoline or gasoline-based solvents to clean clutch components. Brake cleaner can be used to clean components. Wipe the clutch components with a clean cloth, then discard it in a covered container.
Removing
1. Turn out bolts of fastening of the working cylinder of coupling (see paragraph 4), but do not disconnect the piping from it. Take the cylinder aside and tie it with a piece of wire.
Caution: After disconnecting the slave cylinder, do not depress the clutch pedal.
2. Remove the gearbox (see chapter 7A).
3. Remove the clutch fork from the articulated support, then remove the release bearing from the neck of the input shaft of the gearbox along with the fork (pic. 7.3).
Examination
4. Hold the release bearing by the outer ring, rotate the inner ring, applying force to it (pic. 7.4). If the bearing rotates with binding or has play, replace the bearing. Wipe the bearing with a clean cloth, then carefully inspect it for damage, cracks or other damage. Usually, the release bearing is replaced during clutch disassembly, regardless of its condition. Do not wash the bearing in solvent as this will wash away the grease in the sealed bearing.
5. Inspect the fork for cracks or wear.
Installation
6. Apply some high temperature grease to the release bearing seat in the transmission housing. Also apply some grease to the transmission spline shaft, clutch fork pivot and the front surface of the release bearing (pic. 7.6).
7. Lubricate the clutch fork support, fork ends, and slave cylinder pushrod with high temperature grease (pic. 7.7, a, b).
8. Install the release bearing on the fork.
9. Slide the bearing onto the transmission input shaft and thread the end of the yoke through the hole in the clutch housing. Put the fork on the stand.
10. Apply some high temperature grease to the release bearing surface.
11. The rest of the installation procedure is performed in the reverse order of removal.
