Drain the air conditioning unit – for the ve-
hicles with air conditioning (see chapter 62” Fill-
ing –Draining the air conditioning circuit”). Disconnect the battery
Dismount the air inlet duct from the battery
screen. Detach from clips the oi l reservoir from the
battery screen, for the ve hicles equipped with
power steering. Clamp the hoses from radiator by means of
MOT 453 device.
Dismount the hoses from radiator by means
of the pliers for elastic clips MOT 1202-01 and
recover the cooling fluid.
Disconnect the engine fan connector (1).
Detach the wiring from clips ( 2) and (3).
Di sconnect the resistance connector ( 4), for
the vehicles with air conditioning. Carefully release the engine fan from the four
attachment clips ( 5) on the radiator- for the

The vehicles without air conditioning. Carefully remove the engine fan from the
sustaining p oints (7).
Dism oun t t he ra di a t or of f t he si de
attachment supports on the radiator upper
cross beam. Disconnect the two pipes from condenser.
Re l ease t he ra di ator from the lowe r

with air conditioning).
For vehicles with air conditioning.
REMOU NT I NG
Mount the condenser on the new cooling
radiator (for vehicles with air conditioning).
M ount the radiator-condenser assembly
on the vehicle, by supporting it in the lower
elastic supports and attach it in the supports
of the radiator upper cross beam. Mount the engine fan assembly on the
sustaining supports (7) and attach it in the four
screws (for vehicles without air conditioning).

r adio-cassettes player, e lectronic clock, etc, there are t o be re-programmed before returning
the vehicle to the client.
Check the engine fan operation: start the vehicle engine and disconnect the water
temperature sensor. The engine fan must start. Reconnect the water temperature sensor
then by means of the CLIP tester erase the memorized failure corresponding to the water
temperature sensor.

COOLING ENGINE FAN NOT WORKING
(for vehicles without air conditioning)
Replace fuse
F01
.
Check fuse F01 from engine compartment. Is it good?
Replace water temperature sensor.
Replace the control relay of the cooling engine fan.
Replace the cooling engine fan assembly . Start the vehicle’s
engine.
Disconnect the water
temperature sensor. Is the
cooling engine fan working?
Check the control relay of the cooling engine fan Is it good?
Is any voltage between pins 1
and 2 of the cooling engine fan connector?
The wirin g
is
damaged. Fix it. Stop the vehicle engine.
Check the continuity and resistance
against vehicle mass between:
- pin B2 connector of water temperature sensor pin 13 UCE i njection;
- pin B1 connector of water temperature sensor pin 73 UCE i njection;
- pin 3 connector of cooling engine fan control relay exit fuse F01;
- pin 5 connector of cooling engine fan control relay pin 2 connector of
cooling engine fan
- pin 1 connector of cooling engine fan vehicle mass;
- pin 1 connector of cooling engine fan control relay pin D 5 connector
of actuators relay;
- pin 2 connector of cooling engine fan control relay pin 8 UCE injection.
Ar e they good?
Replace UCE injection.

SHAFTS
THE PRIMARY
SHAFT
.
The primary shaft shall not be repaired and is not adjustable.
The shaft has a groove ( B) for oiling the 5-th gear free pinion.
Clean the oiling – groove of the 5 th gear
The oil seal ring in front of the shaft and the bearing cams are in direct contact with the shaft.
Check the condition of the shaft surface in the operation area ( A) of the oil seal; ring , and if
this shows ridges or irregularities, it will be replaced.
R EPLACING THE BEARINGS OF THE PRIMARY SHAFT
The bearings of the primary shaft are freely mounted on it
There are two types of bearings: - a cylindrical one with balls, pressed into the mechanism crankcase;
- a cylindrical one with rolls, pressed into the clutch-differential crankcase, together with
the clutch shaft oil seal ring.
The bearings replacement is to be done only with identical bearings with the original
ones.

Adjust:-the shoes, by applying a repeated pressure to the brake pedal;
- the rear axle bearing clearanc;
- the handbrake ( see c hapter 37).
Mount the wheel.
Lower the vehicle on the ground.
Tighten the wheels screws to the required moment.
Pu rge the braking system (see chapter 38).
REPAIRING
DISMOUNTIN G
Dismount the brake cylinder off the vehicle;
Dismo unt :
- the purging screw;
- the protection bellows;
-the Ö22 pistons assembled with the pressure gaskets.
Check the condition of the cylinder boring, any trace of wear, oxidation or scratches implies
the replacement of the assembled brake cylinder.
If the cylinder components are in a good condition, lubricate them with brake fluid and mount
them in the reverse order of dismounting .
Check the easy moving of the assembled pistons in the cylinder boring.
Mount the brake cylinder on the plate;
Mount the wheel brake drum.
Check the adjustment of the hand brake.
Purge the braking system.
