Remove oil from tank 9 (see fig. 5-3) power steering.
Pic. 5-3. Power steering system:
1 - power steering oil pump;
2 - heat exchanger;
3 - gasket 2108-3512115;
4 - bolt-fitting M16x1.5 2123-3408144;
5 - high pressure hose;
6 - screw clamp 2108-1300080-60;
7 - gasket 1/02824/60;
8 - bolt-fitting M14x1.5 2123-3408070;
9 - oil tank;
10 - oil tank mounting bracket;
11 - screw clamp 2108-130008050;
12 - low pressure hose;
13 - low pressure drain hose;
14 - steering mechanism;
15 - supply hose.
Unscrew the bolt 4 fastening the hose 5 to the pump 1 and the clamp 6 of the hose 15 and disconnect the hoses from the pump (see fig. 5-3). Use process plugs in hose ends to prevent fluid loss from the power steering system.
Loosen the accessory drive belt tension by turning the tension adjusting bolt counterclockwise and remove the belt from the power steering pump pulley.
Turn away bolts of fastening of the pump of the hydraulic booster to an arm and remove the pump.
Installation. Install the pump in the reverse order of removal.
Tension the accessory drive belt by turning the adjusting screw clockwise. The deflection of the lower branch of the belt in its middle part should be equal to 3.15 -3.70 mm with a force of 75 N (7.5 kgf). The deflection value must correspond to the value of the device for determining the oscillation frequency (120±2) Hz when measured on the top run of the belt.
