- Check the pump casing and the external gears. If there
are any visible signs of deterioration (cracks in the casing
or gear teeth worn too much), change the whole part.
- Overhaul by unscrewing the screws (1) and removing
the gear (2) together with the ball bearing and pin (3).
- Check the bearing and the sliding surfaces of the internal
cage of the bearing and of the pin (3) work properly.
- Then separate the pump cover (4) from the casing (5).
Unscrew the two screws (6) M8x30mm from the top of
the cover and the two screws (7) M8x80mm from the
casing side.
- Check the state of wear of the internal gears (8) and (9).
In addition, check the gear (9) fitted stably on the cover
(4) turns freely.
Always change the seals (12) and O-rings.
Wear or poor rotation of the gear (9) require
changing the cover assembly (4) + (9) + (2) +(3)
supplied as spare parts already fitted.
The cover assembly also includes the bushing in
which the gear spindle (8) turns.
- Fit the gear (8) on the cover assembly (4) and check its
rotation.
- Fit the cover together with the gears on the pump casing
(5).
- Fit the suction strainer on the pump with a new seal:
M8x1.25 screws (tightening torque 22—27 Nm).
- Fit the pump together with the suction strainer to the
crankcase.
The oil pump is secured with three M10x25mm
hexagonal—head screws with a tightening torque of
38—45 Nm, tightening the M8 screws to a torque of
22—27 Nm.
The suction strainer is secured to the cap for the central
support with two M8x25mm hexagonal—head screws
with a torque of 22—27 Nm.
- Fit the oil pipe (10) securing it with the screws (11)
M8x45mm to a tightening torque of 22—27 Nm.
- Lastly, fit the oil sump with a new seal.
Tighten the M10 nuts on the stud bolts of the gearbox
to a torque of 38—45 Nm. The remaining M10x1.5x35
mm screws (24 in all) must be tightened to a torque of
38
÷45 Nm.

- From the front, fit the engine oil filter support (1)
together with the temperature transmitter (2), pressure
sensor (5), the gasket (4) and the filter clog sensor (3).
- Tighten the M8x1.25 fixing screws to a torque of 22—27
Nm.

- Assemble gear (1) with tool 99368517; tighten the fixing
nut to 350 torque (300 Nm with the screwdriver with
final take off at 350 Nm with dynamometric wrench).
- Fit the high—pressure fuel pump together with its driving
gear and seals.
- Tighten the M10x1.5 fixing screws to a torque of 49—60
Nm.
Before tightening the screws (see order in
Figure 71), lubricate them with graphitized oil.
Always fit new gaskets.
Before tightening, lubricate the screws with UTDM
oil or alternatively with engine oil.
- Fit the intake manifolds together with new gaskets on the
heads.
- Tighten the M10x1.25 screws to a torque of 38—45 Nm.
- Fit the diesel supply pipe to the high—pressure pump.
Piping M18x1.5 tighten on the coupling to a torque of
50 Nm.
- Fit the water—oil cooler after changing the two O—rings.
- Tighten the 6 M10x1.5x40 mm screws to a torque of
25—30 Nm.

- Fit the head water outlet pipes (1).
- Fit the seals (2), fit the elbow (3), the connecting pipes
(4) and O-rings and the thermostat casing (5).
The new head—side gaskets have already been fitted
together with the air intake manifolds.
- Tighten all the screws to a torque of 22—27 Nm.
To facilitate assembly, here we describe how to use
the water pipe fixing screws correctly.
