1. Grip the outer casing of the regulator, partly
extract it and, at the same time, rotate it so
that the fins (1) which contain the open­
ings for the fixing bolts are positioned hori­
zontally.
NOTA Do not grip the pressure regulator by
the electrical connector.
Insert the blades of two screwdrivers by the
fins (1) and very carefully extract the pressure
regulator.
NOTE Do not use a screwdriver or other
tools in the seal areas between the
regulator and the pressure pump.
2. Pressure regulator
1. High pressure seal (black or green)
2. Anti-extrusion seal (white)
3. Low pressure seal (black)
NOTE // the high pressure seal accidentally
remains inside the pump casing, turn
the ignition key to the ON position
(engine switched off); this will op­
erate the pump shaft and a small
amount of fuel and the seal will come
out.
NOTE Do not, under any circumstances, use any tools for extracting the high pressure seal and this
could damage the inner surface of the pump.
Refitting
- Suction off any impurities present inside the pump casing.
- Check the condition of the three seals and make sure they are correctly positioned before fitting.
- Slightly lubricate the outer surface of the three seals using vaseline. Do not, under any circumstances,
lubricate the other surfaces of the pressure regulator.
- Insert the pressure regulator in its housing on the pump, pressing gently and, at the same time, rotating
the regulator until it is is contact with the surface of the pump.
NOTE Do not, under any circumstances, use a hammer or other tools when fitting the pressure regula­
tor.
- Fit the two bolts fixing the pressure regulator to the pump acsing. and tighten them to a torque of
0.9±0.1 daNm.
- Reconnect the electrical connector and complete the refitting of the remaining components reversing the
order of the operations carried out for the removal.

COMPRESSOR ( 1596 engine)
The compressor fitted on this version is the HR V5 variable capacity type, illustrated in the diagram below,
and consists of:
- a crankcase (7) which contains the bores in which the pistons (4) slide;
- an assembly comprising a shaft on which an inclined plate (6) is fitted on which a disc (2) guided by
a pin (5) integral with the five connecting rods (3) controlled by the pistons (4) rotates on roller bear­
ings;
- a cylinder head which contains the intake and supply ducts as well as the housing for the regulation
valve (9);
- a plate (8), between the crankcase and the cylinder head, which contains the inlet and supply valves;
- a pulley assembly with an electro-magnet coupling (1).

Operation
The alternating drive required for the sliding of the pistons in the bores/liners is produced by the rotary
motion of the inclined plate (6), whilst the variation in the capacity, dependent on the piston stroke, is
chieved through the alteration in the angle of the disc (2) controlling the connecting rods (3).
The inclination of the above mentioned disc depends on the difference in pressure between the intake
duct and the inside of the compressor. This difference, measured by the bellows (10), operates the regu­
lation valve (9) and consequently causes the movement of the disc (2).
When the request for conditioned air is high, the regulation valve (9) is positioned in such a way that it
uncovers an opening which places the intake side in contact with the inside of the compressor; as, in this
case, there is no difference in pressure, the compressor operates at maximum capacity corresponding to
the position of the disc illustrated in the previous section.
When the air request is less, the valve is positioned so that the supply section is in contact with the crank­
case and, at the same time, it stops the flow between the latter and the intake side activated previously.

COMPRESSOR ( 1998 engine)
The compressor fitted on this version is the SANDEN SD6V12 variable capacity type.
The capacity of the compressor varies starting from the maximum value (125.1 cnrfVrev) and is gradually
reduced (up to 6.2 cm /rev) according to the system load variations. - changed outside temperature
and/or humidity conditions or sharp variations in the engine load.
This solution is defined as "unlimited variable capacity".
The compressor is the alternating piston type: the variation in capacity is achieved by tilting the connect­
ing rod holder plate with a consequent variation of the piston stroke: the movement of the plate is acti­
vated by an internal regulation valve according to the balance of pressure upstream and downstream of
the compressor. In particular a low intake pressure involves the shuttering of the compressor (reduced ca­
pacity), whilst a high pressure involves operation at maximum power (maximum capacity).

PROTECTION AND SAFETY DEVICES
All the vehicle supply lines were designed taking into account the most up-to-date directives in terms of
safety and protection, especially to prevent fires.
There are 2 types of protection:
- active protection, aims to reduce the causes of faults "at source"
- passive protection, aims to limit the effects of a fault as much as possible
The first category includes a carefully designed wiring layout with wires positioned and carefully anchored
on tracks that are repaired and protected if necessary.
The cables connected to the alternator and the motor were modified for this reason by adding protective
caps etc. A strengthened sheath was also introduced for some of the more exposed sections of wiring.
The passive protection includes all interventions to reduce faults due to high current (overload, short cir­
cuit).
All system fuses were rated based on the nominal absorbtion of the loads activated at the same time, to
ensure intervention in cases of a clear short circuit.
The introduction of a box containing 4 maxifuses with other fuses connected on the outside means all
the supplies can be protected except for the cable that connects the battery to the starter motor and the
cable that connects the starter motor to the recharging alternator. These cables are therefore protected by a
strengthened supplementary sheath.
