The amount of oil to be introduced in the
engine is 2.7 liters - without replacing the oi l-
filter - or 2.9 liters, after re placing the filter.
The minimum oil pre ssure at 80

-in the idle mode 1 bar
-at 4000 rot/min 3 bar
The oil pump belongs to the “gearwheel”
type. Take off the cap and a lso the clapper of
the oil-pump.

THE PRIMARY SHAFT
The primary shaft shall not be repaired and is not adjustable.
The shaft has a spry nozzle (B) which cannot be dismounted.
Clean the oiling – groove of the 5 th step
The oil seal ring in front of the shaft and the bearing cams are in direct contact with the shaft.
Check the state of the shaft in the opera tion area ( A) of the oil seal; ring, a nd if this shows
ridges or irregularities, it will be replaced.
REPLACING THE B EARINGS OF T HE 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 crankcase of the mechanism;
- a cylindrical one with rolls , pressed into the crankcase of the clutch-differential, together
with the clutch shaft oil seal ring.
T he bearings replacement is performed only with identical bearings with the original ones.

MANUAL GEARBOX
21 - 20
The differential of the
JH3050 gearbox is the simple type (with two satellite s and two planetary
wheels, one of which making a common body with the tulip of the planetary transmission).
This differential is supported in the clutch – differential crankcase by means of two cylindrical
bearings equipped with balls of various sizes.
The two bearings are pressed in the clutch – differential crankcase.
The crown of the main transmission is assembled by hooping, on the differential crankcase.
DIFFERENTIAL DISMOUNTING
This operation is performed after separating the crankcases. The zero ring (1) is removed from the right planetary shaft, then by means of a pins extractor
and a hammer, the sealing gasket (2 ) is gently hit with a hammer in order to make it pivoting.
The oil seal ring is carefully pulled along the grooved part of the planetary pinion in order
not to deteriorate the grooves.

Dismount the bellows - deflector beari ng
in the same manner l ike t ripod dismounting.
REMOUNTING
In order to be corre ctly positioned on the
s haft, the bearing must be pressed to achieve
the value L = 118 +/- 0.2 mm between the
b ackside of the bearing and the shaft
extremity. This value is obtained by means
of the PF 1331 device, when mounting, its
extremity is at the level of the shaft .
IMPORTANT
In order to avoid the deformation of the bearing, which includes a sealing gasket (annular
oil seal), the pre ssing effort must be constant (do not hammer).

GENERALITIES
GENERALITIES
The purpose of the a ir conditioning unit i s to produce a decrease of t he temperature in the
passengers compartment a nd to obtain a l ower value t emperature compared to the external
environment one, reducing in the same time the air moisture.
MAINTENANCE
For a vehicle equipped with air conditioning, it is recommended a frequent checking of the
refrigerating agent level. During the year it is recommended:
- the checking of the refrigerant fluid filling;
- the cleaning and the air-blowing of the condenser and the cooling radiator fins;
- the checking of the condensation removal pipe on order not to be clogged.
For important leakage repair, for any components replacement (compressor, condenser, etc)
and if moisture was noticed in t he air conditioning circuit, the dryer filter tank is to be replaced
and the unit draining is to be performed. The same is valid also in case the conditioning circuit
remains open without protection covers more than 10 minutes.
IMP ORTANT
Duri ng winter, it is recommended the frequent start of the system, in order to pro-
long the lifetime of the compressor and of the whole system.
The vehicle equipped with an air conditioning system shall be not exposed for more
than 20 minutes i n painting c abin where there are temperatures higher than 80 °C.
It is obligatory the use of the refrigerating agent and compressor oil type prescribed
by the manufacturer. It is absolutely forbidden to perform welding on the elements of the air condition
circ uits. The filling of the air conditioning system can be pe rformed only by m eans of charging
units and observing the instructions of the manufacturer. For mechanical or body
operations it is recommended pi ping protection in order to avoid their disconnection
by accident. Avoid the drip of the oil compressor on the painted vehicle body.
For component replacement implying the circuit draining, it is absolutely necessary
the use of new parts and of a special oil for compressor.

AIR CONDITIONING

The compressor is absorbing the vapors coming from the evaporator at low pressure and
temperature, is compressing them and convey the gas at high temperature and pressure. The refrigerant fluid in high pressure and temperature vapor condition is entering in the second
he at exchanger, which by condensation is transmitting the heat to the external environmental.
At the exit from the condenser, the refrigerant fl uid is in liquid condition, at a high pressure and temperature.
Type of compressor: SD 7Y15
Compressor oil : PAG SP 10 or SP20, volume –135 cmc.
Refrigerant: HFC 134 a, quantity of refrigerant : 0.590 kg

Disconnect the compressor’s connection.
Disconnect the pipes from the compressor.
Dismount the belt tensioning screw and release the belt.

Dismount the compressor.
Replace the compressor.
