a
a If replacing the four high pressure pipes:
-loosen the injector rail nuts by a few turns (the in-
jector rail should be loose).
II - REFITTING OPERATION
a Remove the blanking plugs.
a Insert the high pressure pipe olive in the injector high
pressure inlet taper.
a Position the high pressure pipe olive in the high
pressure outlet taper of the injector rail.
a Finger tighten the high pressure pipe nuts, starting
with the nut at the injector end.
a Slightly pretighten the high pressure pipe nuts.
a Mount a new clip provided with the new high pres-
sure pipe.
a If replacing the four high pressure pipes, torque
tighten the injector rail nuts (28 N.m).
a Torque tighten in order the « pump - rail » high
pressure pipe nuts (28 N.m) :
- injectors end,
- on the injector rail end.
III - FINAL OPERATION

WARNING
Before fitting a new high pressure pipe, lightly
lubricate the nut threads with oil from the applica-
tor provided with the new part.
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-lubricating.
WARNING
Do not remove the blanking plugs from each
component until the last moment.
Note:
The assembly order of the « rail-injector » high
pressure pipes is not important.
Note:
Tighten each pipe fully before moving on to the
next pipe.
