10.4. Removal, check of a state and installation of the release bearing and fork of switching off of coupling

Remember that the dust produced in the course of wear of frictional overlays of the conducted clutch plate may contain noxious to health asbestos. Do not blow off dust compressed air and try not to inhale it. Do not apply to rubbing of components of coupling solvents on an oil basis, - use only special brake cleaners or pure methyl alcohol. Put the used rags before utilization in hermetically closed container.


Removal

 PERFORMANCE ORDER

1. Remove assembly of the executive cylinder of coupling (see the Section Removal and installation of the executive cylinder of coupling).
2. Remove the transmission (see the Head the Manual transmission).
3. Remove the holder of the lever of switching off of coupling from a spherical finger of a spherical support.

4. Try to remember how fingers of the lever of switching off fasten on the release bearing a spring clamp. Remove the bearing from assembly of the lever, then - from a pin of a main shaft of the transmission. Remove the coupling switching off lever. estimate a condition of a rubber protective cover of the lever, in case of need replace a boot. Estimate a condition of the wire holder of the lever, in case of need make replacement. Check the lever of switching off of coupling for existence of cracks and signs of deformations.


Check

 PERFORMANCE ORDER

Holding the bearing for an external holder, press two fingers internal and rotate it. The bearing has to rotate freely and silently, otherwise it needs to be replaced. Wipe the bearing with pure rags and examine on existence of signs of wear, cracks and other mechanical damages. Usually replacement of the release bearing is made every time at service of components of coupling. Do not wash out the bearing in solvent in order to avoid violation of tightness of its assembly at all.


Installation

 PERFORMANCE ORDER

1. Grease the contact surfaces of the lever of switching off of coupling with refractory lubricant. In case of need put on the place the new spring holder. Fill lubricant in an internal flute of the release bearing. Also grease the holder of the bearing on a pin of a main shaft.

2. Install the release bearing on assembly of the lever of switching off, - track reliability of fixing of components.
3. Grease with refractory lubricant the surface of a spherical finger of a spherical support of the lever, pass the lever through a boot, put the bearing on a shaft pin, then latch the lever on a support finger. Check freedom of movement of the bearing on a shaft pin.

4. Slightly grease with high-temperature lubricant the surface of the release bearing contacting to petals of a diaphragm spring of a press disk.
5. Further installation is made as it should be the return to an order of dismantle of components. Track, bolts of fastening of transmission to the engine were tightened with the required effort (see Specifications to the Head the Manual transmission).
