7. Frictional disk
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.
| PERFORMANCE ORDER
| 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.
