ENGINE
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.

There are two possible solutions for manufactu-
ring this plate.
1)By modifying the existing plate on the E7J en-
gine (air filter support plate mounted onto the
cylinder head).
2)By having it manufactured locally
Parts list: - 1 plate of thickness 4 or
5 mm in semi-hard steel,
-
2 HEX M8 × 20 bolts (collar
bolts).

Insert the driveshaft stub axle into the hub.
It should enter freely until the thread shows allo-
wing the stub axle nut to be fitted.
If any problems arise, use tool T. Av. 602. Right hand side
With the protector in place, coat the splines of the
seal on the gearbox side with
MOLYKOTE BR2
grease.
Position the driveshaft with respect to the sun-
wheel and engage it.
Check its position with the angled pin of tool

NOTE :
chamfers on the leading edges of the sun-
wheels make it easier to fit new roll pins.
