Removal and installation of a belt of a drive of the pump
Removal
Remove a headlight from outside the forward passenger.
Remove a belt of a drive of the pump in a following order:

Fig. 6.17. An arrangement of an adjusting bolt (1) back arm and a bolt (2) fastenings of the pump




- ослабьте an adjusting bolt 1 (fig. 6.17) a back arm;
- ослабьте a bolt 2;

Fig. 6.18. An arrangement of an adjusting bolt (1) forward arms and a direction of moving (2) for pump removal




- ослабьте adjusting bolts 1 (fig. 6.18) a forward arm;
- Move the pump 2 forward and remove it.
Installation
Establish приводной a generator belt.

Fig. 6.19. An arrangement and the moments of an inhaling of bolts of fastening (1) forward arms, a back arm (2) and the pump (3)




Tighten an adjusting bolt 1 (fig. 6.19) a forward arm the moment 18—22 Нм.
Tighten an adjusting bolt 2 back arms the moment 20—24 Нм.
Tighten a bolt of 3 fastenings of the pump of the hydraulic booster of a steering the moment 20—24 Нм.
Establish a headlight from outside the forward passenger.
Removal and installation of a pulley of the pump
Removal
Remove a forward right headlight.
Remove a pulley of the pump of the hydraulic booster of a steering in a following order:
- Remove a belt of a drive of the pump;

Fig. 6.20. Use of holder DW310—020 (1) for fixing of a pulley from проворачивания at отворачивании nuts (2)




- Using holder DW310—020 1 (fig. 6.20), fix a pulley from проворачивания;
- Turn away a nut 2 pulleys of a drive of the pump.
Installation
Establish a pulley of a drive of the pump and fix a nut. For fixing of a pulley from проворачивания at a nut tightening use holder DW310—020. Tighten a nut of a pulley of a drive of the pump the moment 55—69 Нм.
Establish the right headlight.
Removal and pump installation
Removal
Remove the right headlight.

Fig. 6.21. Removal of a hose (1) lines of giving and the union of a tube (2) lines of pressure of the hydraulic booster of a wheel




Disconnect a hose of a line of giving 1 (fig. 6.21) the wheel hydraulic booster.
Turn away the union of a tube of 2 lines of pressure of the hydraulic booster of a wheel.
Remove the pump of the hydraulic booster of a steering in a following order:
- Remove a belt of a drive of the pump;

Fig. 6.22. An arrangement of an electric socket (1) and bolts (2) fastenings of the pump




- Disconnect a socket 1 (fig. 6.22) the switch of pressure of the hydraulic booster of a steering;
- Turn out bolts 2;

Fig. 6.23. An arrangement of a bolt (1) fastenings of the pump




- Turn out a bolt 1 (fig. 6.23).
