Coupling is dry, one-disk diaphragm type with the hydraulic drive.

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

Check

PERFORMANCE ORDER

1. Check liquid level, if necessary restore (if the tank is empty, then add liquid and pump over a hydraulic actuator). Define the leak reason.

2. For check of pro-slipping of coupling press a pedal idling of the engine and several seconds later turn on the reverse gear. The gnash will indicate the increased 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. Several times switch from the 1st transfer to back. The complicated switching indicates wear of details. Check the course of a rod of the working cylinder at completely pressed pedal. If the course is small, then check liquid level.

4. Check a condition of the directing bearing, be convinced that the clutch release fork lever has no side play on an axis.
