Clutch parts
1. Flywheel; 2. Friction disc; 3. Clutch housing; 4. Bolt; 5. Release bearing; 6. Fork; 7. Spherical fork support; 8. Cover
Places to check friction disc wear
1. Overlays; 2. Damper springs; 3. Hub; 4. Rivets
Wear of spring petals
1. Normal wear of petals; 2. Increased wear; 3. Increased wear of petals; 4. Breakage or deformation of the spring petals
Removal
1. When describing the procedures, it is assumed that the work is performed without removing the engine.
2. Remove the slave cylinder, set it aside and secure it.
3. Hang up the engine and remove the transmission. If the engine is supported from below, keep in mind that the oil receiver is located near the pan and if the pan is deformed, the oil access to the engine may be blocked.
4. Secure the clutch by inserting the mandrel.
5. Find the alignment marks (designated by the letters X or O), if they are absent, mark the position of the clutch on the flywheel.
6. Loosen the 6 bolts gradually and evenly in a diagonal sequence until the spring force is released, then remove the bolts and remove the clutch cover and friction disc.
Examination
1. As a rule, only the friction disc requires replacement. However, the condition of all parts should be inspected.
2. Check the flywheel condition. It is recommended to remove the flywheel and grind it regardless of the surface condition.
3. Check the condition of the friction lining surface, measure the distance to the disc rivet heads, which should be at least 1.5 mm. Check the condition of the springs, loose rivets, and other signs of damage (see fig. Places to check friction disc wear). It is recommended to replace the disk regardless of its condition.
4. Along with the friction disc, the release bearing is usually also replaced.
5. Check the condition of the surface of the pressure plate, diaphragm spring and spring petals (see Fig. Wear of spring petals). Minor defects of the disc can be sanded with sandpaper; in case of significant defects, replace the clutch.
Installation
1. Clean the flywheel and clutch thoroughly.
2. Install the clutch by aligning the marks and tighten the bolts by hand. Mark "flywheel side" (to the flywheel) must be facing the flywheel.
3. Center the disc using a drift that should fit into the flywheel recess, tighten the clutch bolts gradually and evenly in a cross pattern.
4. Lubricate the release bearing groove and all rubbing surfaces with high-melting grease. Install the release bearing.
5. Install the transmission and all removed parts.
