23.19.1. Removal of pressure and filling of hydraulic system

Pressure removal

PERFORMANCE ORDER
1. Before a detachment of any of hoses it is necessary to remove pressure in hydraulic system of a being self-leveled back suspension bracket.
2. Lift a back part of the car and fix on supports.
3. Working under the car, clear the pumping union in the top part of the control unit of system of a being self-leveled back suspension bracket.
4. Dress on the pumping union the pure transparent hose which other end place in capacity.
5. Weaken the pumping union on the control unit, merge 500 mm of liquid in capacity and tighten the union of pumping the demanded 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. Lift liquid level in the accumulator of pressure of a control system of a being self-leveled back suspension bracket to the maximum mark.
2. Unscrew a nut, fixing connecting bent for to the control unit lever. Remove draft from the lever and move the lever up against the stop.
3. Start the engine, then increase engine turns to 2 000 – 3 000 rpm and let's to it work on these turns during 30 seconds, 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 demanded moment.
5. Check liquid level in the accumulator of pressure of system of a being self-leveled back suspension bracket.

System filling on the car established on wheels

PERFORMANCE ORDER
1. Lift liquid level on the accumulator of pressure of system of a being self-leveled back suspension bracket to the maximum mark.
2. Put in a luggage carrier cargo it is powerful 120 kg. Thus the control unit will be established 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 to it work on these turns 1 minute, then switch off it.
4. Take cargo from a luggage carrier and check liquid level in the accumulator of pressure of system of a being self-leveled back suspension bracket.
