SPECIAL NOTES FOR VEHICLES FITTED WITH A
DRIVER’S AIRBAG
IMPORTANT
To avoid any risks of destroying the rotary switch
under the steering wheel, comply with the
following instructions:
• Before removing the steering column and the
rack, the steering wheel MUST be immobilised
with the wheels straight using a "steering
wheel locking" tool, throughout the whole
operation.
• Any doubts about whether the steering wheel
is centred means that the steering wheel will
have to be removed so that the centring
method described in section 88 "Airbag" can
be applied.
REMINDER: in this case, only qualified, trained
staff can carry out this operation.
- the gear control at the gearbox end (turn it
over and attach it to the exhaust pipe),
- the horn
- the expansion bottle (attach it to the engine)
- the earth strap

REFITTING
The engine sub-frame can be easily aligned with
the bodywork by positioning the two
approximately 100 mm long threaded rods into
the two front mountings of the body sub-frame .
Refitting is the reverse of removal.
Tighten the sub-frame mounting bolts to a torque
of :
•6 daN.m at the front,
•11 daN.m at the rear.
If the vehicle has manual steering, position the
shock absorber mountings into the holes (A), and
into holes (B) for power assisted steering.
92114-1R
When the left and right hand suspended
mountings are refitted, remember to remove the
block under the gearbox and tool Mot. 1159
ADJUSTING THE LONGITUDINAL MOVEMENT
LIMITER
Slacken the two limiter bolts (E).
Insert the centring fork tool Mot. 1289-03 into the
openings in the suspended mounting cover.
Tighten the two limiter mounting bolts (E) to a
torque of6 daN.m.
Tighten all bolt, nuts and screws to the
recommended torques.
Fit the caliper mounting bolts using Loctite

torque.
Press the brake pedal several times to bring the
pistons back into contact with the pads.
