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.

ANTIPOLLUTION
Oil vapour rebreathing circuit: Descriptions
K9K
14A
I - PRESENTATION OF THE CIRCUIT
Operating phase A
Operating phase BOperating phase A :
-with the engine at low load, the vacuum in the air pipe
at the air filter box outlet is not sufficient to activate the
membrane of the oil vapour rebreathing valve, fitted
with a weighted spring. Oil vapours are aspirated in
large quantities due to the vacuum in the air pipe at
the air filter box outlet.
Operating phase B :
-At engine medium and high load, the vacuum in the
pipe at the air filter box outlet attracts the membrane
of the oil vapour rebreathing valve. The hole allowing
the oil vapours to pass through in large quantities is
therefore closed and the oil vapours are aspirated in
low quantities via a calibrated jet.
II - CHECK
To ensure the antipollution system works properly, the
oil vapour rebreathing circuit must be kept clean and in
good condition.

REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aDisconnect the battery (see Battery: Removal - Re-
fitting) (80A, Battery).
II - REMOVAL OPERATION
aUnclip:
-the fuel filter on the fuel vapour absorber in the di-
rection of the arrow (1) ,
-the fuel vapour absorber in the direction of the ar-
row (2) . IMPORTANT
During this oper ation, be sure to:
-refrain from smoking or bringing red hot objects
close to the working area,
-be careful of fuel splashes when disconnecting the
union.
IMPORTANT
Wear goggles with side protectors for this opera-
tion.
IMPORTANT
Wear leaktight gloves (Nitrile type) for this opera-
tion.
WARNING
To avoid any corrosion or damage, protect the
areas on which fuel is likely to run.
WARNING
Keep the pipe unions away from contaminated
areas.
WARNING
To prevent impurities from entering the circuit, place
