GENERAL INFORMATION

Prevention

The dust formed as a result of wear of coupling may contain asbestos which is hazardous to health! Do not inhale it.


Removal

PERFORMANCE ORDER
1. Lift a forward part the car and install it on support. Remove the left forward wheel.
2. Turn off fixing bolts and uncover a coupling case.
3. Remove the mud panel of a wheel niche.
4. Disconnect a weight wire from a transmission cover.
5. Install a container under the transmission for collecting oil, then turn off fixing bolts and uncover.
6. Remove laying.
7. Remove a lock ring from an entrance shaft.
8. Using a special key, turn off a bolt on the end of an entrance shaft.
9. Remove an entrance shaft (a photo on the right) by means of the special tool (a detail of N KM-556-1-A and KM-556-4) or made independently (a photo at the left).
10. For removal of coupling press the disk needs to be pressed to a diaphragm spring.
11. For this purpose it is possible to use special clips (a detail of N KM-526-A) or to make the. The sizes are given in the drawing.
12. Ask the assistant to squeeze out a pedal of coupling and install clips on press a drive (a photo at the left). Turn a bent shaft after installation of each clip.
13. Gradually turn off six bolts fixing a coupling casing to a flywheel (a photo at the left). Pay attention to the mark in a flywheel combined with a ledge in a coupling casing (it is specified by an arrow a photo on the right).
14. Remove coupling from the car.

Survey

PERFORMANCE ORDER
1. Dust coupling by a dry rag.
2. Examine a frictional surface on existence of wear, the loosened rivets or pollution. Examine press a disk on existence of deformation, cracks, the broken plates of a diaphragm spring and wear of shliyets. Replace a disk if it is necessary.
3. Examine surfaces of a flywheel and a press disk. If they are strongly scratched or on them there are flutes or cracks, replace them.
4. Check a condition of the release bearing.

Installation

PERFORMANCE ORDER
1. Install three clips on press a clutch plate. Install coupling on the car. You watch that elements of coupling and a flywheel were pure, and on them oil or lubricant did not get. Before installation grease vents of a frictional disk with molybdenic lubricant.
2. Establish an entrance shaft of the transmission into place. You do not knock on a shaft the hammer as it can damage the transmission.
3. Turn press a disk so that the mark in a flywheel coincided with a cut on a coupling casing. Then establish, and gradually tighten six fixing bolts in a diagonal order (do not forget to establish spring washers).
4. Squeeze out a pedal of coupling and remove three clips from a press disk. redny left support of the engine.
5. Further installation is carried out upside-down removals.
