7.4.3. Search and elimination of malfunctions in hydraulic system of the amplifier of steering

Are included in the package of works on elimination of malfunctions of a hydraulic system:
1) preparatory operations which need to be executed before measurement of pressure:
— check the level and a condition of hydraulic oil, if necessary add (replace) hydraulic oil and pump over system;
— check a tension and a condition of a poliklinovy belt;
— check fastening of the pump of the amplifier of a steering urpvleniye;
2) connection of the measuring equipment:
— cover the generator with paper for protection against oil;

Fig. 7.27. Connection of the manometer for check of hydraulic system: 1 — the pump;
2 — a tank; 3 — the steering mechanism; 4 — the manometer


— connect the manometer 999 5055 between the pump and a delivery hose from the case of the steering mechanism (fig. 7.27). For connection use unions 999 5175 and 999 5319: close the union 999 5175 by means of a bolt of "banjo" and rings of the coupling 999 5319; connect a hose from the manometer crane to a final hose of the case of the steering mechanism; the handle of the crane of the manometer arrange along a hose;
— start the engine;
— pump over system; wait, so far hydraulic oil and the pump of the amplifier of steering will not get warm up to the working temperature (about 80 °C);
3) check of a hose of high pressure:
— check a hose of high pressure for existence of a blockage and leaks, clean and replace if necessary;
— repeat check;
4) check of high pressure:
— close the final crane of the manometer on
3 with, write down value of pressure; repeat this measurement two more times; it is impossible to close the crane more than for 10 min. as the pump of the amplifier of steering can be damaged. Value of nominal pressure — 0,96 MPas, fluctuations of pressure should not exceed 0,35 MPas;
— if pressure corresponds to nominal, connect a hose of high pressure to the pump of the amplifier of steering and pump over system;
— if pressure is higher nominal, fluctuations of pressure exceed 0,35 MPas, execute the operation "Check and Cleaning of the Operating Valve";
— if pressure is lower nominal, fluctuations of pressure within 0,35 MPas execute the operation "Replacement of the Operating Valve";
5) check of a servobalans at turn of a steering wheel:
— start the engine;
— turn a steering wheel almost against the stop to the right;
— establish a dynamometer key 999 8081 on a nut of fastening of a steering wheel; slowly turn a shaft of a steering wheel for the handle of a dynamometer key to the right and remember value of torque when the manometer shows 1,2 MPas;
— turn a steering wheel almost against the stop to the left and remember value of torque as well as at turn to the right. Value of torque has to be ranging from 2,8 to 4,0 N · m, and the difference of values at turn of a wheel should not exceed 0,7 N · m to the right and to the left. If the difference exceeds this value, replace the case of the steering mechanism;
6) check of pressure of the pump:
— start the engine;
— turn a steering wheel against the stop to the left and detain it in this situation during 10 with, reading out indications of the manometer;
— turn a steering wheel against the stop to the right, consider indications of the manometer. Nominal pressure — 0,96 MPas;
7) removal of the measuring equipment:
— cover the generator with paper for protection against oil hit;
— remove the measuring equipment and unions, connect a delivery hose to the pump, using a new sealing ring;
— fill a tank of the amplifier of steering with oil and pump over system;
— park the car on the parking brake and launch the engine;
— several times turn a steering wheel from an emphasis against the stop;
— check that everything works normally and there is no oil leak;
— check the level of oil and add if necessary. In system of the amplifier of steering it is necessary to apply oil ATF-F, G, Dexron D/E Ford Mercon;
h) check and cleaning of the operating valve:

Fig. 7.28. Dismantling of the operating pump valve


— turn off and take out the operating valve (fig. 7.28);
— clear details and remove the available damages by a fine-grained grinding skin (600);
— establish a new sealing ring, and then deliver to a detail of the operating valve into place;
— tighten the operating valve the moment of 75 N · m;
— check a condition of hydraulic oil; if oil pure, repeat check of pressure; if oil is polluted, remove the pump, clear it and replace oil, then repeat check of pressure. If the operating valve is polluted, it is also necessary to clean the pump of the amplifier of steering;
i) replacement of the operating valve:
— disconnect the final pipeline from the pump of the amplifier of steering;
— replace the operating valve;
— connect the final pipeline;
— add hydraulic oil in system;
— repeat measurement of pressure;
— if the measured values do not meet standard even after repeated measurement, replace the pump of the amplifier of steering;
j) replacement of a ring of an epiploon of the leading shaft of the pump of the amplifier of steering:
— remove the pump of the amplifier of steering;

Fig. 7.29. Epiploon installation site


— remove an epiploon ring from the leading shaft (fig. 7.29);
— check whether there are no damages and zadir on working surfaces of the leading shaft;
— establish a new ring of an epiploon;
— install the pump of the amplifier of steering;
— delay all connections of tubes;
— fill a tank of the amplifier of steering with hydraulic oil and pump over system.
