Connect the fuel pipe (4) to the hydraulic accumulator (7)
and to the high-pressure pump (5).
With wrench (2) of series 99317915 and dynamometric
wrench 99389829 (1), tighten pipe fittings (3 and 6) at
prescribed torque.

Connect fuel pipe (3) to high-pressure pump (1) pipe union.
Secure the pipe by means of clamp (2).
Fit a new rubber top (5) onto pipe (4), then secure the latter
to inlet manifold (8) by means of bracket (6) and tighten
screw (7) to the prescribed torque.

Fit coolant pipe (2) into the engine base.
Screw down screw (1), then tighten it to the prescribed
torque.
Fit oil dipstick pipe (4), together with a new seal ring, into the
engine base.
Screw down pipe (2 and 4) fastening nut (3) to the inlet
manifold, then tighten it to the prescribed torque.

Whenever they get removed, the fuel pipes (4)
must be replaced with new ones.

Connect exhaust manifold (1), together with a new gasket
and complete with elbow (3) and pipe (2), to the cylinder
head again. Fit spacers (4) into place, screw down nuts (5),
then tighten them to the prescribed torque.

Connect turboblower (5), together with a new gasket, to
exhaust manifold (1) again. Screw down nuts (2) then tighten
them to the prescribed torque.

Fit heat exchanger (5), together with EGR valve (6), back into
place, by proceeding as follows:

- position (by placing a new gasket in between) heat

exchanger (5) onto pipe (4), then screw down screws
(3) securing to bracket (2) by a few turns;

- position a new gasket onto elbow (8), then screw down

screws (7) securing EGR valve (6) to elbow (8);

- tighten nuts (4) and screws (3 and 7) to the prescribed

torque.

Press the clips (3) in the direction shown by the arrow and
connect the fuel recovery pipe fittings (1) to the
electro-injectors (2).

Before fitting the turbocharger on the engine, it is
necessary to fill the central body with engine
lubricating oil.

NOTE

Connect oil pipe (4) to turboblower (5) and to the coupling
on the cylinder head, and tighten the fasteners to the
prescribed torque.

Fit pipe union (1), together with a new seal ring, into place,
then screw down screw (2) then tighten it to the prescribed
torque.
Screw down screws (3) securing elbow (4) to bracket (5),
then tighten them to the prescribed torque.

clamps):

- (3), to heat exchanger (1) pipe union and EGR valve (5);

- (2), to heat exchanger (1) and pipe union (7);

- (6), to pipe union (7) and EGR valve (5);

- (4), to heat exchanger (1) pipe union.

Fit oil filling pipe union (3), together with a new seal ring,
screw down screws (4), then tighten them to the prescribed
torque.
Fit bracket (1) into place, screw down screws (2), then
tighten them to the prescribed torque.

Fit coalescence filter (1) into place, screw down screws (2),
then tighten them to the prescribed torque.
Connect pipe (3) to coalescence filter (1), screw down nut
(4), then tighten it to the prescribed torque.
