Check

It is recommended to execute following preliminary checks which allow to define a condition of coupling and deterioration of its details.

PERFORMANCE ORDER
1. Check up liquid level, if necessary restore (if the tank is empty, add a liquid and pump over a hydrodrive). Define the leak reason.
2. For check of proslipping of coupling press a pedal idling the engine and after some seconds include a reverse gear. The gnash will specify in the strengthened deterioration of press or frictional disks.
3. Check up completeness of deenergizing 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 some times switched from 1st transfer to the back. The complicated switching specifies in deterioration of details. Check up a course of a rod of the working cylinder at completely pressed pedal. For this purpose insert into a special crack a metal strip and press to a rod.
4. Ask the assistant to press a pedal and to release, – the strip thus will leave a scratch which length is equal to a rod course. The rod course should be equal 20 mm. If the course is small, air hit, подтекание cylinder consolidations, or jamming of a disk of coupling on primary to a check point shaft can be the reason.
5. Check up a condition of the plug of an axis of a pedal, be convinced that the pedal freely moves.
