1. Disconnect a pressure head hose from the pump and connect the device for measurement of pressure OK201 323 AA0 between a hose and the pump. The inhaling moment: 39–59 Nm |
The prevention Before a hose detachment put labels for correct its repeated installation.
|
| 2. Insert the thermometer in пополнительный a tank of the amplifier of a steering. |
3. Remove air from hydraulic system of the amplifier of a steering as follows:
– Check up liquid level in пополнительном a tank and, if necessary, finish it to the normal;
– Lift the car and fix on support;
– Turn a steering wheel from an emphasis against the stop 10 times;
– Repeatedly check up liquid level in пополнительном a tank and, if necessary, finish it to the normal;
– Repeat steps 3 and 4 until liquid level in a tank is not stabilised;
– Start up the engine and leave it to work on frequency of idling;
– Turn a steering wheel from an emphasis against the stop 10 times;
– Check up that the liquid in пополнительном a tank does not foam.
If the liquid foams, means in it there is air and it is necessary for removing, for what repeat steps 2–7. |
The prevention If the liquid still foams, check up tightness of hydraulic system of the amplifier of a steering.
|
| 4. Check up temperature of a liquid of hydraulic system of the amplifier of a steering. If the temperature is not in limits 50–60 °C, turn a steering wheel from an emphasis against the stop until the temperature of a liquid will not reach demanded value. |
The prevention To read value of pressure, the analyzer valve is necessary for closing for short time. If the valve to leave closed during more than 15 with, the liquid temperature will increase excessively and will damage the oil pump.
|
|
|
5. Completely close the valve. Increase frequency of rotation of the engine to 1000–1500 mines-1 and measure the pressure of a liquid created by the pump. Pressure of a liquid created by the pump of the amplifier of a steering: 7,358–7,848 кПа
|
If pressure is in demanded limits, it is possible to spend the further checks.
If pressure below demanded values, repair or replace the pump of the amplifier of a steering.
If pressure above demanded values, check up a contamination of tubes and repair or replace them or the pump of the amplifier of a steering. |
| 6. Completely open the valve. Increase frequency of rotation of the engine to 1000–1500 mines-1 and measure the pressure of a liquid created by the pump. |
The prevention To exclude damages, do not keep a steering wheel turned against the stop during more 15 with.
|
| 7. Turn a steering wheel from an emphasis against the stop some times and measure the pressure of a liquid created by gear wheels of the pump. If pressure below demanded, replace or repair steering transfer. Pressure of a liquid created by gear wheels of the pump of the amplifier: 7,358–7,848 кПа
|
| 8. Remove the device for pressure measurement. Establish into place and fix a pressure head hose. Tighten connection of a hose by the demanded moment. The inhaling moment: 16–24 Nm
|
| 9. Remove the thermometer and remove air from hydraulic system of the amplifier of a steering. |
