IDENTIFICATION - DATA - TIGHTENING TORQUES STEERING

1 - IDENTIFICATION

(1) Power steering mechanism with integral ram .

(2) Distributor valve pinion .

(3) Reservoir .

(4) Power steering pump .

(5) High pressure flexible pipe .

(6) Low pressure flexible pipe .

(7) Steering fluid radiator fitted to the front panel (Fitted only on driving school versions) .

1 - 1 - STEERING MECHANISM

The steering mechanism is mounted on to the sub-frame; retained by two stud bolts fitted with two nuts .

IMPERATIVE : when replacing a stud use the correct tightening torque (0.75 daN.m), as otherwise the steering unit may be damaged .

The power assisted steering systems are of the integral ram type .

The valves are groove type (ZF make) .

A clamp secured to the oil intake pipe is used for mounting the pump oil intake pipe and the pipe returning the oil to the reservoir .

The tappet is adjusted by means of a screwed plug (A) .

(X) Pre-adjustment .

1 - 2 - POWER STEERING ELECTRIC PUMP ASSEMBLY

The oil reservoir (8) is fitted on an electro-pump assembly with output controlled by ecu .

1 - 3 - BULKHEAD CROSSMEMBER SEAL

A seal (9) on the passenger compartment side acts as an acoustic seal, and retains the carpets and sound insulation .

A second seal (10), secured to the steering mechanism (or the power steering valve) on the engine side, acts as a seal against water and dust .

1 - 4 - STEERING COLUMN

The height and depth of the steering wheel can be adjusted over 40 mm; it is fitted with a disengageable sleeve; it consists of the following components :

a short body to leave as much space as possible free above the pedal bracket
a safety system at the top permitting the energy to be absorbed over 50 mm in the event of an impact

The upper fixings (11) and the lower fixings (12) of the steering column are nuts (the studs being solid with the steering column support) .

The lower part (13) is equipped with a slide to ease mounting, prevent adjustment and allow retraction in the event of an impact (travel 95 mm) .
