Pump mounting on different modifications varies. Therefore, the following description should be related to the recommendations for the type of engine installed. On fig. 264 shows the location of the pump on a non-turbocharged diesel engine. On fig. 265 the pump is shown on a turbocharged engine. To start work, you need to free the front of the car. Remove the power steering pump in the following order:
Pic. 263. Checking the fluid level in the power steering
- unscrew the cap of the reservoir of the hydraulic booster (see fig. 263) and pump out fluid from the hydraulic drive system. At the same time, do not allow liquid to get on the painted parts of the car. For pumping out, a rubber bulb is best suited, the tip of which is lowered into the tank;
- unscrew the union nut of the flexible hose 1 (see fig. 264 and 265) high pressure. There is an o-ring underneath. When assembling, tighten the nut with a torque of 35–40 Nm;
- unscrew the bolts securing the pulley 3 of the hydraulic booster pump, holding the pulley from turning. On gasoline and diesel engines without turbocharging, first remove the air intake hose;
- remove drive belt (see sect. «Cooling system») and take out the pulley;
- unscrew the pump 4. Remove it and drain the remaining liquid in it.
Assembly is carried out in the reverse order. Tighten the pump mounting bolts to 21 Nm, pulley bolts to 30 Nm. After assembly is complete, fill the system with fluid as described above and bleed.
