GENERAL INFORMATION

Check of a condition of a diaphragm spring of the leading knot of coupling


Sequence of a tightening of bolts of fastening of the leading part of coupling to a flywheel


Prevention

The dust which is formed during the work of coupling and besieged on its details may contain asbestos, unhealthy. Do not blow dust compressed air and do not inhale it. For removal of dust do not use solvents on the basis of gasoline. For removal of dirt use a cleaner for brake system.


Removal

Usually access to a disk of coupling is provided after removal of a transmission. Thus the engine remains in the car. If the engine is removed for capital repairs, always use this opportunity for check of coupling on wear and, if necessary, replace it.

PERFORMANCE ORDER
1. On the hummock drive of coupling disconnect a coupling cable from a coupling switching off fork. On the hydraulic drive of coupling remove the working cylinder of coupling, without disconnecting from it a hydraulic hose and, using a soft wire, suspend the working cylinder of coupling in a motor compartment.
2. Remove a transmission. Thus a fork of switching off of coupling and the bearing remain vyzhimny in a coupling case.
3. Attentively check a flywheel and press a disk for existence of tags (are specified by an arrow), and at their absence put them.
4. Using a screw-driver, record a gear wreath of a flywheel from a provorachivaniye. Gradually in diagonal sequence weaken bolts (are specified by shooters) the leading knot of coupling, turning each bolt on a half of a turn until it is terminated springs and bolts can be unscrewed manually.
5. When unscrewing bolts of fastening of the leading part of coupling use a special mandrel for support of the leading part of coupling and a disk of coupling.

Check

Usually, when there is a malfunction of coupling, it is connected with wear of a disk of coupling. However at this time it is necessary to check all details of coupling.

PERFORMANCE ORDER
1. Check a flywheel for existence of cracks, an overheat, scratches and other damages. If damages small, pierce a working surface of a flywheel.
2. Check a condition of the bearing located in a back end face of a cranked shaft.
3. Check a condition of overlays of a disk of coupling. Slips have to act on 1,6 mm over heads of rivets.
4. Check a coupling disk for weakening of rivets, deformation, the broken springs, cracks and other obvious damages (points of check of a condition of a disk of coupling are specified by shooters). Usually the disk of coupling is replaced at the first opportunity therefore if there are doubts in its state, replace it new.
5. Together with a disk of coupling it is desirable to replace vyzhimny the bearing.
6. Check a condition of a working surface of a press disk.
7. Check petals of a diaphragm spring. If the working surface of a press disk has flutes, scratches or damages, replace press a disk. If the diaphragm spring is worn-out or damaged or there is a suspicion that elasticity of a spring changed, it is necessary to replace knot of the leading disk (see rice. Check of a condition of a diaphragm spring of the leading knot of coupling).

Installation

Before installation carefully wipe working surfaces of a flywheel and a press disk. It is important that on these surfaces and on overlays of a disk of coupling there was no oil and greasing.

PERFORMANCE ORDER
1. Establish a disk of coupling and press a disk on a flywheel and by hand in diagonal sequence screw bolts of fastening of a press disk.
2. Center a coupling disk, having inserted a mandrel through a coupling disk into the bearing in an end face of a cranked shaft. Gradually and in the sequence shown on rice. Sequence of a tightening of bolts of fastening of the leading part of coupling to a flywheel tighten bolts of fastening of the leading part of coupling to a flywheel.
3. Apply a thin film of high-temperature greasing on surfaces of friction of the vyzhimny bearing and working surfaces of a fork of switching off of coupling.
