COOLING - EXHAUST - TANK
Cooling engine fan for vehicles with air conditioning
DISMOUNTIN G
Disconnect the battery (-) terminal.
Remove the air inlet pipe from the attachment of the battery screen.
Detach from clip the power steering oil reservoir from the battery screen.
Disconnect the engine fan connector ( 1)
Detach wiring from clips ( 2) and (3).
Disconnect the connector of the cooling engine fan resistance (4).
Carefully dismount the engine fan assembly from the radiator, from sustaining points (5).
REMOUNTING
Check the condition of the fan impeller and of the engine fan electric motor.
Carefully mount the engine fan assembly in the sustaining points (5).
Connect the connector of the engine fan resistance ( 4).
Connect the cooling engine fan connector ( 1) and attach it in clip (3) then in clip (2).
Attach in clips the power steering oil reservoir on the battery screen. Mount the air inlet
pipe.
Connect the battery (-) terminal. In case the vehicle is equipped with programmable
r adio-cassettes player, electronic 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.

ATTENTION !
Th
e dismounting and checking of the parts must be done on a surface coated with rub-
be r or soft plastic.
Before taking apart the gearbox from the vehicle, drain the oil from the gearbox.
DISMOUNTIN G
Dismount :
- clutch re lease fork ( 1) ;
- pressure bearing ( 2) ;
- the screws located inside the c lutch
crankcase.
Dismount the cap attachment screws.
The back c ap of the gearbox is extracted
so that its setting surface should is remaining
parallel to the c onjoined surface of the gear-
box, because this cap is containing an oiling
groove situated in the cylinder bore of the pri-
mary shaft. Engage the
1-st gear with the control lever
and the 5-th gear by manually shifting of the 5-
th gear fork. Dismount the primary shaft nut and the sec-
ondary shaft screw.

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.

Gearbox dismounting
The stopping rings are to be replaced after each dismounting.
For mounting and dismounting the stopping rings, a pair of safety pincers to keep the ends
apart, and, on the opposite side, a pair of flat tipped pincers to prevent the stopping ring
breaking, are to be used.
SECONDARY SHAFT REASSEMBLING
Before reassembling the secondary shaft, perform the parts checking, as follows: -the pinions and claws tooth must not show chips or excessive wear;
- ensure that working surfaces of the shafts and the inner parts of the pinions do not show
traces of gripping or abnormal wear. When reassemblin g, clean the oiling grooves made in the secondary shaft and all its component
parts are to be pre – oi led. Take into consideration that synchroniser hubs are matched with the slidings.
It is recommended to mark the positions of the sliding compared to the hubs.
The stopping rings are to be replaced after every dismounting.
Reassembling of the secondary shaft shall be done by performing the dismounting operations
in the reverse order.
