Coupling dry, one-disk diafragmenny type with a hydraulic drive.

Consistently main and working cylinders through which effort transfer from a pedal on a fork and on vyzhimny the bearing of switching off of coupling is provided are switched on in a contour of a hydraulic actuator.

Adjustment of coupling is carried out automatically.

Indications of wear of coupling are pro-slipping and a characteristic howling sound at transfer inclusion. In this case considerable wear of a flywheel and a press disk is possible.

Wear of a frictional disk depends on skills of driving, wear is accelerated by frequent application of pro-slipping, or driving with breakthroughs owing to pedal "throwing". Roughly frictional disk should be changed through 64000 km.

It is recommended to execute the following preliminary checks which allow to define a coupling condition.

1. Check liquid level, if necessary restore (if the tank is empty, add liquid and pump over a hydraulic actuator).
2. For check of pro-slipping of coupling press a pedal idling the engine and some seconds later include a reverse gear. The gnash will indicate the strengthened wear of press or frictional disks.
3. Check completeness of switching off of coupling.
4. For this purpose on the working engine press a coupling pedal so that the pedal did not reach a floor on 13 mm.
5. Be several times switched from the 1st transfer to the back. The complicated switching indicates wear of details.
6. Check a course of a rod of the working cylinder at completely pressed pedal. If the course is small, check liquid level.
7. Check a condition of the directing bearing, be convinced that the fork of coupling has no люфта on an axis.
