OPERATION
NOTE: The technique required for removal of the injector will depend on which system is fitted to the
vehicle. Always use an external adaptor first if possible. If by using reasonable force the injector 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.
NOTE: When connecting the ball joint adaptor to the male thread adapter, keep the ball stud in the correct
position. To protect the threads all screw connections must be tightened.
EXTERNAL THREAD ADAPTOR
Fig. A: Use a suitable socket to remove the electrical unit.
Fig. B: 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 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 injector threads.
Fig. C: Connect the sliding hammer to ball joint adapter
and to the external thread adapter. The injector can now be
removed by using reasonable force on the sliding hammer.
When an injector has been removed, it is recommended
that only a new or refurbished injector is fitted. Follow
manufacturers fitting and safety instructions.
INTERNAL THREAD ADAPTOR
Fig. D: Insert and turn anti-clockwise a special hex socket
to remove the inner sleeve.
Fig. E: Screw the appropriate internal adaptor (5) into the
threads of the injector and tighten with a suitable spanner.
Fig. F: Screw the sliding hammer assembly securely onto
the adaptor. The injector can now be removed by using
reasonable force on the sliding hammer.
Attention: Be prepared for the sudden release of the
injector from the cylinder head.
When an injector has been removed, it is recommended
that only a new or refurbished injector is fitted. Follow
manufacturers fitting and safety instructions.
