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.
