REMOVAL
Remove the air filter.
Remove the air temperature cover (see previous
page).
Remove the injector (6) from its housing.

REFITTING
Replace the O rings and lubricate them.
Fit the injector and cover so that they are correctly
aligned and mount the assembly.
REMOVING - REFITTING THE FUEL PRESSURE
REGULATOR
The fuel pressure regulator cannot be adjusted if
it is faulty. The upper section of the throttle body
must be renewed.
IDLE SPEED REGULATION MOTOR
REMOVAL
Remove the air filter.
The motor may be removed without having to
remove the throttle body. Access to the bolts is
made easier however by removing the mounting
bolts for the throttle body and releasing it
without disconnecting the fuel pipes.
Disconnect the motor connector.
Remove the mounting bolts and remove the
motor.
REFITTING
No adjustment may be made. However, ignition
on, if the low load switch bargraph on the XR25 is
not illuminated, fit a shim between the throttle
stop and the micromotor to obtain the no load
switch position.
Turn the ignition on then off; the micromotor
should position itself in the cold start position.
Repeat the operation without the shim, then
check the position of the throttle, ignition on,
engine not running, using the XR25 and #17.

THROTTLE POTENTIOMETER
The throttle potentiometer is set in the factory
and cannot be repaired.
If there is a fault, renew the throttle body section.
REMOVAL
Remove the air filter and the complete
monopoint throttle body assembly (see previous
pages).
Remove the upper section of the throttle body
and the idle speed regulation motor.

REFITTING
Renew the seals.
Refit the throttle body peripherals.
Check:
- the connectors are correctly connected,
- on the
XR25 :
•the bargraphs are present for :
- low load,
- full load.
•the throttle position using the XR25 and
#17.
Refit the air filter.

Injectors
13
F3R engine
The injectors fitted to this type of engine are of
the type "SIEMENS DEKA 2".
They are mounted on the fuel gallery.Each
injector is sealed by two O rings.
Fuel circulates permanently around the
circumference of the injector body. This fuel
washing prevents bubbles of fuel vapour forming
and aids warm starting.

IMPORTANT : there are no special notes for
removing the injectors. The fuel gallery must
however be removed beforehand since the fuel in
the gallery would enter the cylinder concerned.
When any operation involves removal of an
injector, new O rings and flat seals under the
gallery must be fitted.
NOTE : when refitting the upper seal, use the
tapered ring provided with the kit of seals.

SPECIAL TOOLING REQUIRED
Mot. 1265 Pliers for removing quick release
unions
LOCATION
The fuel filter is located under the vehicle in front
of the fuel tank.
99214R
REPLACEMENT
Replace the fuel filter at each major service.
REMOVAL
Before removing the filter, take precautions to
catch the fuel which will run out (do not clamp
the pipes as they will be damaged).
Remove the clips (1).
Disconnect the pipes with quick release unions (2)
using tool Mot. 1265.
Remove bolt (3) and remove the fuel filter.
REFITTING
Observe the direction of fuel flow (marked by an
arrow on the filter).
Reconnect the pipes by hand (it is not necessary to
use tool Mot. 1265).
Ensure the quick release unions are correctly
connected.
Refit the safety clips (1).
