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

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). Define the leak reason.
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. For this purpose on the working engine press a coupling pedal so that the pedal did not reach a floor on 6 mm. Be several times switched from the 1st transfer to the back. The complicated switching indicates wear of details. Check a course of a rod of the working cylinder at completely pressed pedal. If the course is small, check liquid level.
4. Check a condition of the directing bearing, be convinced that the fork of coupling has no люфта on an axis.
