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.
