aparts always to be replaced: Front sub-frame
bolt
II - REFITTING OPERATION FOR PART
CONCERNED
aCheck that there is an indexing pin on the high pres-
sure pump shaft.
aPosition the high pressure pump on the cylinder
head whilst inserting it in its pulley.aFit the air filter unit bracket.
aFit the high pressure pump bolts on the cylinder
head, without tightening them, until contact is made.
aTighten to torque and in order the high pressure
pump bolts on the cylinder head (23 N.m).
aRefit the high pressure pump pulley, holding the high
pressure pump pulley with a 32 mm spanner.
aTorque tighten the high pressure pump pulley nut
(70 N.m) while holding the high pressure pump pul-
ley using a 32 mm spanner.
aCheck that the timing belt is correctly positioned and
in good condition.
aRemove the (Mot. 1606) from the cylinder head.
III - FINAL OPERATION
aRefit the suspended mounting on the cylinder head.
aTorque tighten the cylinder head suspended
mounting bolts (25 N.m). WARNING
Do not remove the blanking plugs from each
component until the last moment.
Also, do not remove the components from their
packaging until they are to be fitted to the vehi-
cle.
Note:
Check that the high pressure pump shaft is cor-
rectly orientated in relation to the pulley.

high pressure pump (6 Nm).II - FINAL OPERATION.
a
aFit a new high pressure pipe between the rail and in-
jector number 4.
aFit the high pressure pipe unions between the rail
and injector number 4 until contact is made, without
tightening them.
aFit and lock a new clip between the high pressure
pipes on the rail and injectors number 3 and 4.
aUsing the (Mot. 1746), tighten to torque:
-the high pressure pipe unions between the rail
and injector number 4 (yellow) (24 Nm),
-the high pressure pipe unions between the rail
and injector number 4 (silver) (28 Nm).
aRefit:
-the channel,
-the neck nut.
aFit the neck wiring harness.
aClip the neck on. WARNING
Do not remove the blanking plugs from each
component until the last moment.
Also, do not remove the components from their
packaging until they are to be fitted to the vehi-
cle.
Note:
Do not lubricate the seals with grease or old die-
sel fuel. Use the applicator provided in the kit for
the new part.

WARNING
Before fitting a new high pressure pipe, lightly
lubricate the nut threads with the oil from the
applicator provided in the new parts kit.
Be careful not to allow oil into the high pressure
pipe.
Do not lubricate high pressure pipes supplied
without an applicator, as these high pressure
pipes are self-lubr icating.
