REFITTING
I - REFITTING OPERATION FOR PART
CONCERNED
a
aFit the fuel flow actuator onto the high pressure
pump.
aTighten the fuel flow actuator bolts on the high pres-
sure pump until contact is made, without tightening
them.
aTorque tighten the fuel flow actuator bolts on the
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.
