6.1.5. Pumping of system of a hydraulic actuator of switching off of coupling

Pumping of system of a hydraulic actuator of switching off of coupling is carried out when filling a hydraulic actuator with liquid after its replacement or after the repair of knots of system connected with its depressurization and also at incomplete switching off of coupling at the pedal pressed against the stop that is followed by a characteristic gnash of gear wheels at inclusion.
It will be required to you: brake fluid, a hose for pumping, a key "on 11", capacity for the merged liquid.

Good advice
You carry out work with the assistant on a viewing ditch.

1. Fill in (or add) liquid in a tank to the lower edge of a bulk mouth.
2. Remove a protective cap from the valve for removal of air from system of a hydraulic actuator of switching off of coupling.
3. Put on a hose the valve and lower its free end in the capacity which is partially filled with fresh brake fluid.
4. Press a coupling pedal four-five times and hold it pressed.

Note
The assistant has to press a pedal sharply, with intervals between pressing of 2-3 pages.

5. Unscrew the valve approximately on 3/4 turns — the hose in capacity will come out liquid with vials of air.
6. After the expiration of liquid from a hose stops, wrap the valve, release a coupling pedal.
7. Repeat operations 4-6 before complete cessation of an air outlet from a hose. Usually full removal of air requires about 10 cycles.

Prevention
Do not allow falling of level of liquid in a tank below a tag of "MIN". In due time add liquid, otherwise at drainage of a bottom of a tank will get to system air and pumping it is necessary to repeat anew.

8. Add in a tank brake fluid to a tag of "MAX". Wrap a tank cover.
