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

Q Step 19: Remove the electric radiator cooling fan.
• Step 1: Follow the instructions for removal in reverse
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withdrawn from the hubs, new nuts must be used and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:

—1 Step 5: When the brake calipers have been refitted,
pump the brake pedal until its normal solid feel is restored.
• Step 6: Use a self-grip wrench to reconnect the gear rod
balls and sockets. Use new drive-shaft nuts, tightened to the
correct torque and staked into the shaft grooves with a
punch. See Job 9.
Job 3. Clutch - replacement.
1 - cover plate 2 - driven plate 3 - release bearing
4 - retaining bolt 5 - spring washer
;
Job 3-1
Q Step 1: These first three numbered parts are the parts
you will need to obtain, from your FIAT dealership.
FACT FILE: CLUTCH COMPONENTS
• We strongly recommend that all three
main components: clutch cover, driven
plate and release bearing are replaced
after a high mileage, ensuring longer life
and smoother operation.
• If one is worn, they are all likely to be, so save
yourself another big stripdown in the near future!
LI Step 2: Remove the transmission. See Job 1.
• Step 3: Unscrew the clutch cover bolts (see illustration
Job
3-1,
part 4) progressively until the spring pressure is
released, then remove the bolts. Ease the cover (part 1) off its
dowels and catch the driven plate {part 2) as it falls.
• Step 6: Check the surface of the flywheel that mates
with the clutch, for scoring, or significant micro cracking
caused by excessive head generated by clutch slip. Replace the
flywheel if in doubt.
7ZJ
• Step 7: Check the
release fork pivot, inside
the bellhousing, for wear
Replace the bushes (see
inset) if necessary, lubri-
cating with a small
quantity of molybdenum
disulphide grease.
• Step 8: Replace the bush
(a) by removing the circlip (b)
from the lever shaft (d). Note
the position of the arm (c) on
the splines for refitting and
slide it off. Prise the bush out
using a screwdriver. Lubricate
the new bush with a small
quantity of molybdenum disul-
phide grease and install. Refit
the arm to the fork control
shaft (d) with a new circlip.
Refit the release bearing (e).
• Step 9: Clean any oil (or the protective film) from the
clutch cover and flywheel faces.
• Step 10: Offer the driven plate to the flywheel with the
side having the greatest hub projection facing outwards.
• Step 11: Locate the clutch cover on the flywheel dowels
and screw in the fixing bolts finger tight.
• Step 12: Use an aligning tool to make sure that the
clutch is centralised, otherwise the gearbox will not relocate
on the engine and damage can be caused to the centre plate.
B INSIDE INFORMATION: There is no spigot bush or
bearing in the crankshaft end, but there is an inden-
tation which you can 'feel' with a normal clutch
alignment tool allowing you to centralise the driven
plate between the clutch cover release fingers. B
• Step 5: B INSIDE
INFORMATION: Check
the inside of the
clutch bellhousing for
contamination by oil.
This indicates a leak
from either the
crankshaft rear seal
or the gearbox input
shaft seal (illus-
trated). A faulty seal should be replaced without delay.
Oil can cause judder and slip. Here, the seal (inset) is
being replaced. See PART A: ENGINE, Job 21 for the
position of the rear crankshaft seal. B
• Step 4: B INSIDE
INFORMATION! Check
the inside of the clutch
bell housing for conta-
mination by oil. This
indicates a leak from
either the crankshaft
rear seal or the
gearbox input shaft
seal. Oil can cause
judder and slip.
Replace the gearbox seal by removing the screws holding
in the thrust bearing sleeve (a), prising out the old and
fitting a new seal (b). See PART A: Petrol or Diesel

Job 9. Drive-shaft - removal
and refitting.
IMPORTANT NOTE: For removal of the diesel Turbo's
drive-shaft, see also PART A: ENGINE, Job 18, Step 16A.
G Step 1: Drain the transmission oil.
• 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.

Q Step 3: ...and pull
the gaiter clear.
• Step 4: Remove
the circlip and pull the
CV joint from the shaft.
Q Step 5: Thoroughly clean the joint with petrol or other
agent and dry. Check that the balls and their seats are still in a
good, unbroken shiny condition
-
no score marks. Fit a new
joint if in doubt.
• Step 6: Fit the new gaiter onto the shaft, followed by the
CV joint and circlip. Pack the joint with the grease supplied or
with FL Tutela MRM2 grease.
Q Step 7: Pull the gaiter over the joint and secure with the
retaining band or new screw-type clip. The drive-shaft
assembly is now ready for refitting.
