23.19.1. Removal of pressure and filling of hydraulic system

Removal of pressure

PERFORMANCE ORDER

1. Before a detachment of any of hoses it is necessary to take off pressure in hydraulic system of the self-leveled back suspension bracket.

2. Lift a back part of the car and record on supports.

3. Working under the car, clear the pumping union in the top part of the control unit of system of the self-leveled back suspension bracket.

4. Dress a pure transparent hose which other end place in capacity on the pumping union.

5. Weaken the pumping union on the control unit, merge 500 mm of liquid in capacity and tighten the pumping union the required moment.

Filling of hydraulic system at the lifted back part of the car

Prevention

At installation it is necessary to use a new nut of fastening of connecting draft of the control unit.

PERFORMANCE ORDER

1. Raise liquid level in the accumulator of pressure of a control system of the self-leveled back suspension bracket to the maximum mark.

2. Unscrew a nut, the fixing connecting thirst for the control unit lever. Remove draft from the lever and move the lever up to an emphasis.

3. Start the engine, then increase engine turns to 2 000 – 3 000 rpm and let's it work on these turns during 30 sec., then switch off the engine.

4. Connect connecting draft to the control unit lever, having established it in an external opening of the lever, then screw a new nut of fastening and tighten it the required moment.

5. Check liquid level in the accumulator of pressure of system of the self-leveled back suspension bracket.

Filling of system on the car installed on wheels

PERFORMANCE ORDER

1. Raise liquid level on the accumulator of pressure of system of the self-leveled back suspension bracket to the maximum mark.

2. Put freight weighing 120 kg in a luggage carrier. At the same time the control unit will be installed in such situation at which it is possible to fill and pump over hydraulic system.

3. Start the engine, increase its turns to 2 000 – 3 000 rpm and let's it work on these turns 1 minute, then switch off it.

4. Take freight from a luggage carrier and check liquid level in the accumulator of pressure of system of the self-leveled back suspension bracket.
