SPECIAL NOTES FOR VEHICLES FITTED WITH
DRIVER’S AIRBAG
ATTENTION
:
to prevent any damage being done to the rota-
ting switch under the steering wheel, please fol-
low these instructions :
Before releasing the steering column and the
rack, the steering wheel MUST be immobilised,
wheels straight, using the "steering wheel
locking" tool throughout the duration of the re-
pair. Any doubts regarding the correct centring of
the rotating switch means that the steering
wheel has to be removed so as to apply the cen-
tring method as described in chapter 88 "AIR-
BAG".
REMINDER
: in this case, only qualified personnel
who have received specific training may under-
take this work. Remove:
- the automatic transmission selector control,
- the nut and eccentric bolt (4) (remove it using
the pin extractor) from the steering shaft yoke
after having pushed back the protector.
97390-1S
Remove the nut (A), then, using a copper
hammer, hit the stud in the left hand suspended
mounting in order to remove it.
Put a wedge between the automatic transmission
and the front left hand sub-frame.
PREPARING TOOL MOT. 1040-01
Position the roller pin in the lower holes (G).
It is then secured to the sub-frame using the T-
pieces (I).

- the sub-frame mounting bolts. Secure Mot. 1040-01 under the sub-frame.
Extract the engine and transmission assembly by
lifting the body.
Secure the spring-shock absorber assembly with
rope.
Separate the engine and transmission assembly
from the sub-frame by removing:
- the upper radiator hose,
- the power assisted steering reservoir and the
pump,
- the power assisted steering pipe mounting on
the automatic transmission.
Unclip the wiring loom from the sub-frame.
Position the lifting tool.
Remove:

Separate the gearbox from the engine by :
- removing the starter motor,
- removing the bolts from the automatic trans-
mission sump.
Remove:
- the hoses on the exchanger, Lift the engine from the sub-frame.

- the converter bolts
- the bolts around the gearbox and the TDC sen-
sor.
Separate the automatic transmission from the en-
gine.
REFITTING (special notes)
Refit the converter by positioning it with respect
to the mounting bolts.
Tighten the bolts around the automatic transmis-
sion.
Refitting is the reverse of removal.
Aligning the engine sub-frame with the body will
be made easier by positioning two approximately
100 mmlong threaded rods in the two front sub-
frame-body mountings.
Tighten the sub-frame front mounting bolts to a
torque of 6 daN.m. and to a torque of 11 daN.m at
the rear.
Tighten all nuts and bolts to the re-
commended torque.
Fit the caliper mounting bolts using Loctite
FRENBLOC and tighten them to the correct tor-
que.
Press the brake pedal several times to bring the
pistons back into contact with the brake pads.
Fill:
- the cooling circuit and purge it (see chapter 19),
- the engine with oil if necessary.
NOTE : check that the steering shaft yoke spacer is
in place when refitting.
