Q INSIDE INFORMATION! • The turbo and non-turbo
diesel engines are essentially similar.
• The under-bonnet scene is in some ways different
because of the extra plumbing required when a turbo is
fitted.
• Locations and shapes of various items may differ, or
not exist at all on the non-turbo unit.
• As most complexity is found with the turbo engine,

I

the
following illustrations are mainly of this version.
• The power units are removed from under the car,
therefore make sure you can raise the car enough to
achieve this. Support the car firmly and safely on axle
stands. D

order, referring to Chapter
3,
Facts and Figures for torque
settings and adjustments, lubricant and coolant types and
capacities.
IMPORTANT NOTE: Where the drive-shafts have been
withdrawn from the hubs, new nuts must be used and
staked into their grooves after tightening to the correct
torque.
• Step 16B: D INSIDE INFORMATION!
On the non-turbo version, it is necessary
to undo the drive-shaft-to-hub nuts. These
are very tight and you will require plenty
of leverage while a helper applies the
footbrake very firmly to prevent hub
rotation. Separate the hubs and
suspension struts by removing the pinch
bolts and pulling the hubs clear. Push the
drive-shafts out of the hubs
-
leaving
them fixed at the inboard ends. E3
• Step 17:

Job 2. Transmission refitting
(with engine in car).
/ a 5tep1S: • SLjpp°n the
'' £/ gearbox in such a way that
when disconnecting, it can
be withdrawn smoothly and without 'hanging' on the
engine. A trolley jack might do the job nicely.
• Step 16:
Undo the gearbox
to engine fixing
bolts...
• Step 17: ...slide the
box back until it's clear of
the clutch and lower it to
the ground using a
hydraulic stand or trolley
jack.
IMPORTANT NOTE: Refer to PART A: ENGINE, Jobs 8
and 9 in connection with this Job.
• Step 1: Refitting is the reverse of the removal work
carried out in Job 1 but bear in mind the following:
Q Step 2: Centralise the clutch driven plate, if it has been
disturbed. See Job 3.
• Step 3: NON-HYDRAULIC CLUTCHES ONLY. Adjust the
clutch cable. See Job 4
Q Step 6: Raise the front of the car and support securely on

axle stands.
Remove the road wheels and the previously
slackened hub nuts.
Q Step 7: Remove the wheel arch protective shields.
Q Step 8: Disconnect the speedometer cable from the
gearbox. (If digital instrumentation, disconnect the wiring

from
the sender unit.)
Q Step 9: Disconnect and remove the starter motor and

unplug
the reverse light connector and the earth lead from

the
transmission housing.
Q Step 10: Undo the trackrod ends securing nuts and use a
suitable 'splitter' tool to part the balljoints from the steering

arms.
Slacken the drive-shaft inner boot securing clips. Undo

the pinch
bolts fixing the stub axles to the suspension struts,

pull
the stub axles clear and extract the drive-shafts.
0 Step 11: Support the engine at the gearbox end, just

taking
the weight as described in Step 1.
Q Step 12: Remove the central power unit support (a), the
flywheel guard (b) and the exhaust bracket (c).
• Step 5: With

the
car
still
on the
ground, loosen

the nuts
fixing the
constant velocity

joints
to the hubs.
These require an
enormous force

to be
tightened or
released (see

Chapter 3,
Facts and Figures) and they will have been
staked. There is a severe risk of pulling the car off supports if

you
attempt to undo these nuts while the car is raised off the
ground. Slacken the front wheel nuts.

• Step 8B: Diesel turbo
models have a bolt-on inboard
flange.
• Step 9: Withdraw the shaft
from the transmission (illus-
tration Job
9-8A,
part b).
G Step 2: Ask a helper to apply the footbrake very firmly
while
you
slacken the drive-shaft-to-hub nut, using a long bar
for
good
leverage after
opening out the
staking on the nut, as
far
as
possible. DON'T

do so
with the car off

the
ground because

the
very large force
needed could pull it off

its stands.

uses an inboard CV joint similar to the outer one except
that it has a flange for attachment to the transmission.
(See PART A: ENGINE, Job 18, Step 16A ) Inspect and
replace in the same way as the outer one. The interme-
diate shaft can only be inspected for wear in its bearing
which cannot be removed separately. Therefore, the
whole unit must be changed if defects are found. Q
