REFITTING
It is VITAL to remove the small filter (2) situated at
the bottom of the system using a pair of thin -
nosed pliers, and replace it with a new one.
Tighten the actuator (1) to a torque of 3 daN.m
using the socket Mot. 1440.
Place a new protective cover on the actuator.
Reconnect the two terminals to the connector.Reconnect the connector.
Replace the protective sheath on the wiring,
along with the retaining clip.
Bleed the diesel circuit using the priming pump
before starting the engine.
It is IMPERATIVE to erase the computer memory
by pressing G0**.
It is vital to road test the vehicle after this
operation.

FUNCTION : it acts on the flow in proportion to altitude ; if the vehicle is running at
an altitude greater than or equal to 1 000 metres, the computer reduces the flow by
3 mm
3/stroke. The conventional flow is reestablished if the vehicle runs at an alti-
tude lower than 900 metres.

SPECIAL NOTES
In order to remove the steel pipe connecting the
EGR valve to the air filter, it is necessary to
remove the
EGR valve .

13047-1R2
To remove the EGR solenoid (2), remove the air
filter .
To remove the
EGR valve (1), remove the air filter
first, and replace the seal between the solenoid
valve and the inlet manifold after each removal
operation.

REMOVAL
Place the vehicle on a two post lift.
Remove:
- the air filter inlet pipe,
- the battery,
- the computer support mounting bolts as well
as the connectors at (1), then move the
computer support/ diesel filter assembly to
one side.
13088R3
- the starter mounting bolts and the heat shield
(A),- the starter connections,
- the starter motor itself.
REFITTING
Refitting is the reverse of removal.
Check for the presence of the centring dowel,
which should be located at (B).
