Suitable for the fast and safe removal of Bosch, Delphi, Denso, and Siemens diesel
injectors. Set includes keys and deep, open profile sockets used to dismantle injectors
plus adaptors for attaching the slide hammer securely to the body of the injector. Ball
joint allows hammer to be used in confined areas.
INTRODUCTION& CONTENTS
ASSEMBLY
1. Referring to the individual components in fig.1. assemble the injector puller as shown
in fig.2. overleaf.
2. Use adaptor 6 when the injector is being extracted using the external thread revealed
when the injector cap has been removed.
3. Use one of the adaptors (5) when the injector is being extracted using the internal
thread revealed when the inner sleeve has been removed from the injector.
1. 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.
a. Disconnect the injector wires and connections as per the manufacturer's
instructions.
b. Remove any carbon build up from around the injector.
c. Remove the cap from the injector using the appropriate size socket (8).(fig.3.A.)
2. Use of external adaptor (fig.3).
a. 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.
b. 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.
c. 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.
3. Use of internal adaptor (fig.4).
a. Remove the internal parts from the injector to gain access to use the security hex
key (7). It may be necessary to remove the injector veins by force. Insert the
security hex into the inner sleeve (see D). Turn the security hex anti-clockwise
using a 21mm socket to remove the inner sleeve.
b. Screw the appropriate internal adaptor (5) into the threads of the injector and
tighten with a suitable spanner (see E).
4. Removing the injector.
a. Screw the slide hammer assembly (handle, shaft and sliding hammer) securely
onto the adaptor.
b. The injector can now be removed using reasonable force on the slide hammer. Be
prepared for the sudden release of the injector from the cylinder head.
c. 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.
d. When an injector has been removed, it is recommended that only a new or
refurbished injector is fitted. Follow manufacturers fitting and safety instructions.
