Removing
1. Remove the gearbox.
2. On models with a cable release mechanism, disconnect the release bearing from the clutch release fork and remove the bearing (indicated by an arrow) from the input shaft.
3. Remove the roll pin and remove the clutch release lever from the top of the clutch release shaft. When installing, a new roll pin must be used.
4. On both types of clutches, depress the circlip and remove the upper bushing from the clutch fork shaft.
5. Remove the shaft from the lower bushing and remove it from the clutch housing.
6. Squeeze out the circlip and remove the lower bushing from the clutch housing.
Examination
1. Check the clutch release mechanism and replace worn parts if necessary.
2. Check the release bearing, which should rotate easily, evenly and silently.
3. The working surface of the bearing acting on the pressure spring must be smooth, without cracks, local corrosion or wear. If these defects are present, the release bearing must be replaced. On the leading clutch units of the second type, it is necessary to replace the entire assembly.
Installation
1. Lubricate all pivot points of the shaft and fork contact surfaces with molybdenum disulphide grease.
2. Install the lower clutch housing bushing. Insert the release shaft and upper bushing and secure with circlips.
3. Install the clutch release lever on the shaft, align the holes on the shaft and lever, and insert a new roll pin. Install the release bearing on the gearbox input shaft and connect it to the clutch release fork.
4. Install the gearbox.
