3.1.2. Removal of air from coupling knot

Work process
After works on the hydraulic drive of coupling it is necessary to carry out pumping.
Before pumping extend a pedal of coupling and fill a tank with brake fluid to a mark "max ".
Hit of brake fluid on the transmission is not allowed. If necessary clear the transmission case.
Before turning on of the device for pumping – open the union for pumping.
For filling and pumping of the brake system connect the device to a tank with brake fluid, but do not include.

Dismantle the heat-shielding screen of a power shaft (fig. 3.2) at the left.

All cars

Fig. 3.3. Accession of an air hose to the working cylinder


Attach an air hose And to the working cylinder and open the air valve (fig. 3.3).
Connect an air hose to a pressure head hose of the combined tank.
Now turn on the device for pumping and merge about 100 cm3 of brake fluid.
Working excessive pressure: 2,5 bars.

NOTE
When pumping you monitor the provision of an air hose.

Close the air valve (4,5 N · м).
After pumping several times press through a coupling pedal.
If necessary repeat pumping.
Remove an air hose and put a protective cap.
Disconnect the device for filling and pumping of the brake system from a tank with brake fluid.

To install the heat-shielding screen of a power shaft at the left.

All cars
Establish back thermal insulation (in the presence).

Inhaling moments
The heat-shielding screen of fastening of the drive to the transmission: 23 N · m.
