OPERATION
NOTE: The technique required for removal of the in je ct or will depend on which system is fitted to
the vehicle. Always use an external adaptor first if possible. If by using reasonable force the in je ct or
cannot be removed, use an internal adaptor. Before working on the fuel system, make sure that the
fuel system is NOT pressurised. Refer to the manufacturer's instruction manual on how to de-
pressurise the system. Disconnect the injector wires and connections as per the manufacturer's
instructions. Remove any carbon build up from around the injector. Remove the electrical unit from
the injector.
Use of external adaptor
Identify the external thread adaptor (6) and
separate the inner black part from the outer silver
part by removing the screw from the top of the
adaptor. Position the black part inside the top of the
injector (see B) then place the silver part over it,
and screw it down firmly onto the external threads
revealed when the cap was removed. Install the
screw securely thus locking the adaptor parts tightly
together with the injector thread and wall in
between. This ensures a more secure fastening
and reduces damage to the in je ct or threads.

Use of internal adaptor
Insert and turn anti-clockwise a special hex
socket to remove the inner sleeve (see D).
Screw the appropriate internal adaptor (5) into
the threads of the injector and tighten with a
suitable spanner (see E). Screw the slide
hammer assembly (handle, shaft and sliding
hammer) securely onto the adaptor. The
injector can now be removed using
reasonable force on the slide hammer (see F).
Be prepared for the sudden release of the
injector from the cylinder head. If the injector
cannot be removed, it may be necessary to
consult a main dealer or a diesel specialist, to
avoid damage to the engine. When an injector
has been removed, it is recommended that
only a new or refurbished injector is fitted.
Follow manufacturers fitting and safety
instructions.
