In order to apply to the engine block the engine fixing brackets
99341009 to the stand for the overhaul, operating on the
engine left side, it is necessary:
- to remove the fuel filter (5) from the support (1) by
means of tool 99360076;
- to remove the low pressure fuel pipe (2-3-4) from the
support (1)
- to remove the support (1) bracket from the block
The pipe (3) from the union (4) and from the supercharger
(8).
Remove the fuel pipe (2) from the rail and from the
high-pressure pump (9) and remove it from the engine block,
by removing the fixing screws (4 and 6)
On the right side
Remove the screws (2) and remove the oil pipe (3) from the
supercharger pipe (1) and from the engine block.
Remove the starting engine (5) from the flywheel cover (4).
Apply to the block the bracket 99361037 and fix by means of
these latter the engine to the revolving stand 99322205. Drain
the engine oil by removing the plug from the sump.
Remove the fan from the engine shaft pulley.
!
In order to remove the low-pressure fuel pipe (2-3-4,
Figure 3) from the relevant connection unions, it is
necessary to press the fastener (1) as shown in figure
B.
After removing the pipe, position the fastener (1) into
its lock position, figure A, in order to avoid possible
deformations.
!
When unlocking the pipe (2) union (7), it is necessary
to prevent the union (10) rotation of the high-pressure
pump (9), by using the proper wrench.

Remove the screws (1) and the rail (2).
Remove from the rail: the fuel pipe (7) according to the
procedures described in Figure 4. Remove the fuel pipe (5)
from the rail (2) and from the manifolds (6) for injectors.
!
During the unlocking operation of the pipe (6) fixing
unions (4) from the rail (2), it is necessary to prevent
the possible flow limiting device rotation (3) by
means of a proper wrench.
