Connect the fuel pipes (2) to the electro-injectors (3) and to
the hydraulic accumulator (1).
Tighten the screws (4) fixing the electro-injector brackets (5)
to the prescribed torque.

Using the wrench (2) of the 99317915 series and the torque
wrench 99389829 (1), tighten the fuel pipe fittings (3) and (4)
to the prescribed torque.

Press clamps (3) in the direction shown by the arrow, then
disconnect the connections of fuel recovery pipe (1) to
electric injectors (2).

Whenever they get removed, the fuel pipes must
be replaced with new ones.

Connect the fuel pipe (3) to the hydraulic accumulator (1)
and to the high-pressure pump (8).
Tighten the couplings (2 and 5) using a wrench (7) in the
99317915 series and the torque wrench 99389829 (6).

Fasten the pipe (3) on the support bracket with the bolt (4)
tightened to the prescribed torque.

Whenever they get removed, the fuel pipes (3)
must be replaced with new ones.

Fit the flexible belt (3) equipped with tool 99360191 (2) on
the pulley (4) and apply the tool on the pulley (1).
Turn the drive shaft counterclockwise (

Lubricate the seal ring of the oil filter (2) with engine oil and
fasten it on the heat exchanger (3). Use tool 99360076 (1)
to tighten the oil filter to the prescribed torque.

If present, fit the support (3), drive in the screws (4) and
tighten them to the prescribed torque.
Fit the fixed backstand (2), drive in the screw (1) and tighten
it to the prescribed torque.

Fit the air-conditioner compressor (if any) into place, then
tighten the fastening screws to the specified torque and fit
elastic belt (4) into place, as described below.

To fit the air-conditioner compressor elastic drive
belt into place, tool 99360191 (2) must be used.
Any other tool or method may cause dangerous
tension to the elastic belt.

The elastic belt shall be replaced with a new one
every time it is disassembled.

Fit the pipe (4) of the oil level dip rod and fasten the support
bracket on the cylinder head by tightening the screw (3) to
the prescribed torque.
Fit cooling fan (1), if any, back to electromagnetic joint (2).

Fit on the left and right engine mountings (3) and tighten the
fixing screws to the prescribed torque.
Connect the oil pipe (2) to the turbocharger (1) and to the
crankcase and tighten the fixing screws and the coupling of
the oil pipe (2) to the prescribed torque.

Fit the items below, if any, into place:

- engine cable, by connecting the electric connections of

the same to:
- electric injectors (1);
- preheating plugs (3);
- hydraulic accumulator pressure sensor (5);
- throttle valve actuator (7);
- inlet manifold air pressure/temperature sensor (8);
- high-pressure pump pressure regulator (10);
- phase sensor (2);
- thermostat coolant temperature sensor (9).

- channelling duct (6);
- upper sound-proofing cover (if any);
- fill the engine with lubricating oil of the prescribed grade

and amount.

Fit the swing bar to the engine lifting hooks, then secure the
swing bar to the hoist and take the engine off rotary stand
(12). Take off brackets 99361041 (11).

LUBRICATION

General

The engine is lubricated by forced circulation performed by the
following parts:

- a gear oil pump with built-in depressor (GPOD);

- a pressure relief valve integrated in the oil pump;

- a heat exchanger made up of five elements;

- A double filtration oil filter with built-in safety valve.

Operation (see Figure 283)
Engine oil is drawn up from the sump by the oil pump via
the suction strainer and delivered under pressure to the
heat exchanger where it is cooled.
The oil continues through the oil filter and goes to lubricate
the relevant parts through ducts or pipes.
At the end of the lubrication cycle, the oil returns to the
sump by gravity. The oil filter can be excluded by the safety
valve built into it if it gets clogged.
In addition, the lubricating oil feeds the chain hydraulic
tightening devices for the control of the auxiliary elements
and the timing system and the hydraulic tappet.
