Fig. 5.22. Fastening of a rotary fist


Fix at the left a rotary fist 1 by means of a bandage 2 on an amortisation rack 3 (fig. 5.22).
Turn off a nut.
Wring out a clip.

Fig. 5.23. A clip of an electric cable


Disconnect an electric cable (fig. 5.23).
Take a plastic cover.
On cars with 6 and 8-cylinder engines it is necessary to remove the screen from outside the driver.
That it was possible to remove it, it is necessary to dismantle the forward catalyst.
That it was possible to remove the screen from outside the driver on cars with 8-cylinder engines, it is necessary to dismantle a forward pipe of a final collector.
The screw 1 turn off approximately on 1 turn.

Fig. 5.24. Amplifier removal


Turn away bolts 2 and 3 (fig. 5.24).
The steering amplifier on the party of the driver cast away forward in a movement direction
Substitute the tank for flowing down hydraulic oil.

Fig. 5.25. Untwisting of a hollow bolt


Turn off from the steering mechanism a hollow bolt of a drain hose (22 mm) (fig. 5.25).
On cars with certain combinations of the engine and a transmission the hollow screw can be turned off only from outside a wheel niche.
For this purpose use an open insert of a ring key 22 (standard).

Fig. 5.26. A hollow bolt of a pressure head hose


Turn off from the steering mechanism a hollow bolt of a pressure head hose (19 mm) (fig. 5.26).
On cars with certain combinations of the engine and a transmission the hollow screw it is possible turn off only from outside a wheel niche.
For this purpose use an open insert of a ring key 19 (standard).
Unscrew a bolt 1 (fig. 5.24).
Take the steering mechanism through an arch of the left wheel (the assistant is required).

THE NOTE
Watch, that the gear wheel of the amplifier of a steering has not damaged a cuff of a forward wall.

Installation

Fig. 5.27. The centering screw of the amplifier of a steering


The removed amplifier of a steering align by means of the screw for steering centering (fig. 5.27).
Turn off the screw with internal шестигранником 1 on the steering mechanism.
Shift gear рейку so that centering on рейке has coincided with a carving aperture 2.
The screw for steering centering strongly twirl.
Around a seat of a cuff of a forward wall смажте the amplifier of a steering greasing G 052 745 A3
Establish the amplifier of a steering at a water taking away box (the Assistant is necessary).
Watch that on a carving and surfaces of contact of bolts there was no oil and greasings.
Establish the screw 1, but do not tighten (fig. 5.24).
The steering amplifier on the party of the driver cast away forward in a movement direction
