5.1.2. Steering with the amplifier

Replacement of working liquid
You will hang out forward wheels of the car and establish safety racks under the car.
Disconnect a returnable hose from a tank of a hydraulic system of the amplifier and close a stopper the tank union.
Connect an additional hose to a returnable hose and merge working liquid in suitable capacity.
Disconnect wires of high voltage from ignition coils.
For full discharge of working liquid scroll a bent shaft of the engine several short-term inclusions of a starter at continuous turns of a steering wheel to the left and to the right against the stop.
Connect a returnable hose to a tank and record it a collar.
Fill a tank of a hydraulic system of the amplifier with the recommended liquid.
The recommended working liquid: PSF-3.
Filling capacity: 0,75–0,8 l.
Start the engine.
Check lack of leak of working liquid from connections of hoses, then kill the engine.
Fill a tank with the recommended liquid to the lower position of the filter of a tank.
Remove air from a hydraulic system of the amplifier of steering.

Removal of air from a hydraulic system of the amplifier of steering
Fill a tank of a hydraulic system of the amplifier with the recommended liquid to a tag "MOVE".
You will hang out forward wheels of the car.
Disconnect wires of high voltage from ignition coils. Scroll a bent shaft of the engine several short-term inclusions of a starter at continuous turns of a steering wheel to the left and to the right against the stop five or six times during 15–20 pages.

NOTE
During removal of air it is necessary to add constantly liquid and to watch that its level did not fall below the lower position of the filter.

If to make removal of air at the working engine, then there will be a suction of air and it will get to working liquid. Therefore remove air from a hydraulic system only at a provorachivaniye of a bent shaft of the engine with a starter.
Connect wires of high voltage to ignition coils, then start the engine and leave it to idle.
Turn a steering wheel from an emphasis against the stop before disappearance of vials of air in a tank of a hydraulic system of the amplifier.

NOTE
Do not hold a steering wheel in extreme situation (it is turned against the stop) more than 10 pages.

Make sure that working liquid is transparent, without turbidity, and its level is in a tank between tags "MOVE" and "MIN" on a tank wall.

Fig. 5.10. Scheme of check of change of level of liquid in a tank of the hydraulic booster


Be convinced of minor change of level of liquid in a tank at the left and right turns of a steering wheel (fig. 5.10).

NOTE
If the level of liquid changes more than on 5 mm, then it is necessary to make removal of air from a hydraulic system of the amplifier repeatedly. If liquid level sharply increases after an engine stop then air is removed from a hydraulic system not completely. During incomplete removal of air from a hydraulic system of the amplifier of steering there are extraneous jingling noises from the pump of the hydraulic booster and the valve of regulation of a consumption of liquid that leads to reduction of service life of the pump and other elements of a hydraulic system.

Check of pressure of the pump of the hydraulic booster of steering

Fig. 5.11. The scheme of connection of the manometer for check of pressure of the pump of the hydraulic booster


Disconnect a delivery hose from the pump of the hydraulic booster. Connect special devices between a delivery hose and the pump of the hydraulic booster, as shown in the figure 5.11.
Remove air from a hydraulic system of the amplifier of steering. Then start the engine and on the motionless car turn a steering wheel several times that temperature of liquid rose approximately to 50 °C.
Set power setting of 1000 min.-1.
Completely close the cut-off valve on the measuring manometer, measure pressure of giving of the pump of the hydraulic booster and check its compliance to nominal rate.
Pressure of giving of the pump (nominal rate): 7500–8200 kPa.

ATTENTION
It is not necessary to leave the cut-off valve on the measuring manometer closed more than on 10 pages.

Disconnect special devices, connect a delivery hose and delay fastenings of a hose the specified moment of an inhaling of 55-65 N · m.
Remove air from a hydraulic system of the amplifier of steering.
