DIESEL EQUIPMENT
Coded solenoid valve
13
On this type of vehicle, the replacement of the
solenoid valve and of the coded electronic unit (A)
requires the removal of the injection pump from
the engine.
REMOVAL
With the pump on the bench, remove the protec-
tive fittings at (B).
These are secured by shear bolts which may be re-
moved either :
- using a small cold chisel or a punch and hitting
on the conical heads of bolts (C), (D) and (E)
to loosen them,
- using tool Mot. 1372 for bolt (F), drilling it
using the 4 mm diameter drill (drilling depth
approximately 4 mm) and the large diameter
drilling guide tube on the fitting side (2).
Use extractor (3) and its handle to remove it .
REFITTING
Tighten the fuel cut off solenoid valve to a torque
of 2 daN.m.
Refit a heat shrink cover on the fuel cut off sole-
noid, ensuring the wiring is correctly routed.
Refit the fittings using shear bolts and observing
their location and that of the spacers,
(depending on fitting).
IMPORTANT : using a torque wrench, tighten the
bolts, then remove the bolt heads by bending
them using a tube inserted in the bolt heads.
Location of bolts :
D :
∅ 5 x 25 mm ; torque =0.55 daN.m
C and F :
∅ 6 x 40 mm ; torque =1.2 daN.m
E :
∅ 5 x 33 mm ; torque =0.55 daN.m
Refit the cable of the fast idle speed LDA and
tighten the cable grip, leaving 2 mm play.
Refit the injection pump on the engine.

Remove :
- the fuel supply pipe (A),
- the fuel return pipe (B),
- the pump connector (C),
- the accelerator cable (D),
- the vacuum pipe (E) connected to the fast
idle speed LDA,
- the high pressure wiring loom using tool Mot.

Fit tool Mot. 1200 or Mot. 1317 , for retaining the
pump pulley.

Inserting a torx screwdriver in the gaps of the
RAM pulley, slacken:
- the three bolts mounting the pump
- the central nut securing the pump shaft to the
RAM pulley.
Slacken the central nut and all three of the bolts
mounting the pump until they are completely
free.
Extract the pump.
REFITTING
Clean the pump shaft very thoroughly, using sol-
vent to eliminate all trace of grease.
Refit the pump.
Tighten the three bolts mounting the pump .
Pretighten the central nut of the pump to 2
daN.m.
IMPORTANT : it is vital to carry out a pretighte-
ning operation before the final tightening; tigh-
ten the central pump nut to a torque of 4.5
daN.m.
Carry out the timing operations (see "Pump -
Timing").
For all other operations, refitting is the reverse of
removal.

CHECKING CANISTER BLEED OPERATION
Incorrect operation of the system may cause the
idle speed to be unstable or the engine to stall.
Check the conformity of the circuit (see
operational diagrams)
Be sure to check that the pipe marked "CAN" on
the solenoid valve is correctly connected to the
canister.
Check the condition of the pipes to the fuel tank.

2Canister bleed solenoid valve
3Canister
4Fuel tankAt idle speed connect a pressure gauge
(- 3 ; +3 bars) (Mot. 1311-01) to the "CAN" outlet
on the solenoid valve, to check there is no vacuum
(the command value read by the
XR25 for #23 re-
mains minimal X = 0.7 % ). Is there a vacuum ?
YESIgnition off, use a vacuum pump to apply a
vacuum of 500 mbars to the solenoid valve
at (C). This should not vary by more than 10
mbars in 30 seconds.
Does the pressure vary?
YESThe solenoid valve is faulty. Renew it. Air
must be blown into the pipe (A) connecting
the solenoid valve to the canister to remove
any particles of active carbon.
NOThere is an electrical fault. Check the circuit.
NOUnder bleeding conditions (not at idle
speed, engine warm), the vacuum should
increase (the value for #23 on the XR25
should also be seen to increase).

DRAINING THE FUEL TANK ( Diesel version)
Since Diesel versions are not fitted with an electri-
cal fuel pump, a manual pump must be used to
drain the tank.
For example, the
INTAIRCO pneumatic siphoning
pump is suitable for this operation (see
EQUIPMENT catalogue),
Shunt tracks 3 and 5 and let the fuel flow until it
runs out in intermittent jets.
Disconnect the shunt.
Reconnect the relay.
Disconnect the battery.Remove the pump-sender unit steel access cover.
Remove the clip which shows if the assembly has
been pushed in (if fitted).
Disconnect the quick release union at (1), tool
Mot. 1265.
