- Remove the pipes (1) to the blow-by filter (2) from the
flywheel side.
- Undo the 4 bolts fixing the filter casing to the air intake
manifolds from the turbocharger body to the heat
exchanger (air/air intercooler) removed previously
together with the air filters.
- Loosen the bands (3) on both sides of the hoses near
the turbochargers.
- Undo the bolts from underneath the bracket above the
flywheel to release the manifold (4). Remove the
manifold securing it appropriately.
After having checked the cleanliness inside the
NOTE
manifold, seal the three ends to preserve it.
Check the wear of the hoses in the case of obvious
signs of cracks or if there is a loss in the normal
flexibility replace them.
Figure 6
- Remove the lubrication pipes from both turbines:
disconnect the oil intake pipe (1) from the crankcase at
the top flange on the body of the turbo—blower and the
exhaust pipe (2) from the bottom of the body of the
turbo—blower and from the seat on the sump.
- Also remove the oil pipes at the sump from the blow-by
filter removed previously.
- Remove the band fastening the pipe on the flywheel
casing and then undo it from the flange on the engine
sump.

- Loosen the rail check u-bolt (4) fixing screws.
- Disassemble the assembly of the delivery pipes (1) from
the high pressure pump (2) and the ones on the
electro-injectors;
unscrew the washers (3) with a 99368506 wrench.
- Remove the rail assembly
- Disassemble the diesel fuel exhaust pipes from the
overpressure valve rail (5).
Plug all the pipes in order to prevent possible
NOTE
contamination. Unscrew the fittings seeing to
protect the seal surfaces.
If it is hard to disassemble, loosen the washers of the
NOTE
electro-injector supply pipes on the rail side, of the
compensation pipes between the rail and the rail
side supply.

NOTE The RAIL assembly for GRIFFON applications is
shown on page 21 of the section 2.
On the bench separate the pipes that are between the rail and
the support. Check the conditions of the thread seal conic
surfaces. Plug all pipes in order to prevent contamination
NOTE If there is a malfunction with components (2), (4)
or (5), replace the rail assembly (1).
- Remove all the diesel return pipes: those of the injectors
and the one from the high—pressure pump.
