The engine design allows the injection pump to
be removed and installed without disturbing the
engine timing.
An aperture providing access to the injection
pump sprocket is provided in the front cover
and by using the sprocket retaining plate and
the location pins the pump sprocket can be
held in place whilst the pump is removed.
Fuel Injection Pump Removal
Ensure the engine is cold.
Disconnect the battery and drain coolant via
the lower hose.
Remove the radiator and detach the PAS
reservoir (move to one side).
Remove bonnet lock platform and disconnect
pipes/plug from EVR valve.
In addition, detach fuel filter, air intake duct and
fuel pipes from pump.
Remove EGR valve, inlet manifold and
disconnect cylinder head temperature sensor
lead.
Remove the injector pipes from the pump.
NOTE: Remove pipes 1 and 2, followed by 3
and 4, and disconnect injection pump electrical
connector.
Access Cover Removal Plate
NOTE: The Access Cover Removal Plate is
also used to adjust the final positioning of the
Sprocket Retaining Plate to allow location pins
to be fully inserted, and to remove/install the
crankshaft front oil seal.
To remove the pump sprocket access cover,
locate the 3 studs on the Removal Plate in the
recesses on the cover and using the square
drive turn the Removal Plate anti-clockwise to
remove cover.
Establish the crankshaft timing position, as
described in "Engine Timing" section, by using
the injection pump timing hole as a guide.
Insert the appropriate Flywheel Locking Pin .
The crankshaft is now at 50° BTDC.
The injection pump securing bolts must be
released, using a TX45 socket, to achieve
disconnection of the pump body. NOTE: These
securing bolts cannot be fully removed.
Injection Pump Sprocket Retaining Plate Set
Comprises - Retaining Plate and 3 x
Location Pins.
Fit the Retaining Plate into the access cover
aperture and turn the Plate clockwise so that
the 'spring clips' mounted on the rear of the
Plate locate behind the aperture 'lugs' and
secure the Plate in the aperture.
Continue to turn the Plate until the 3 x holes in
the Plate align with the 3 x securing bolt holes.
Insert the 3 Location Pins through the holes in
the Plate and, if possible, into the securing bolt
holes
IMPORTANT: At this stage you must ensure
that at least one of the pins is fully located.
