- Remove the manifold (1) between the turbo—blower (2)

and the intercooler (3), loosening the clamp (4) on the
manifold and on the turbo—blower .

- Remove the exhaust pipe (5) between the waste gate

valve (7) and the pipe of the turbo—blower.

- Remove the air pipe (6) between the turbo—blower and

- Proceed as follows:

Undo the screws of the collars (1) securing the pipes (2)
to the intake ducts.
Undo bolts (3) securing fastening collars (9) that join
pipes (2) to fittings (4) on the engine blocks by means
of gaiters (10).

- Unscrew the fixing screws and remove the water outlet

pipes (1) from the heads.

- Remove the thermostat casing (5).

Figure 24

- Remove the driving gear with the aid of tools 99368516

(1), 99368517 (2) that permit unscrewing the M24 x 1.5
nut (3).

- Then remove the engine water/oil cooler (2),

unscrewing the M10 x 40 mm screws (three on both
sides).

- Remove the diesel supply pipe from the high—pressure

pump (the coupling has been removed together with the
ADEM III control unit support).

- Remove the diesel recovery piping.

- Remove the intake manifolds (3), remove the gaskets

and remove the high pressure pump (4) from the
flywheel casing complete with gear.

- From the front side disassemble the engine oil filter

supports (1) including the oil temperature transmitters
(2), the pressure sensor (5), the seal (4) and the filter clog
sensor (3).

- Remove the remaining diesel pipe from the LPP to the

filter mounting (the two components have already been
removed previously)

- Remove the electro—injectors. Using the wrench (2),

unscrew the screw (1) of the fixing bracket.

- Fit the tool 99368505 (1) and the wrench for extracting

the electro—injector.

- Unscrew the fixing screws (1) and remove the tappet

cover (2). Repeat this operation for all the covers.

- Remove the rocker arms (2) from the support (1), taking

out the circlips and seals on both sides of the support.
Extract the rods (3) from their seat on the heads and the
jumpers (4).

- Unscrew the fixing screws (7) and remove the head (6).

Remove the cases (5) protecting the valves.

NOTE

NOTE

Note down the position of the tappet covers in
relation to the heads so as to fit them in the
positions they had with the first assembly.

The screws (7) fixing the head on the crankcase
have different sizes:
M15x170
M15x185
Mark them so as to facilitate the assembly phase.
