UNIQUE REPAIR PROCEDURES

O-Ring Replacement
• Carefully remove and replace the external
O-rings. The injector nozzle gasket can be
installed using a 12-point 9mm deep-well
socket. The socket is used to apply even
pressure around the gasket during installation.
• The connector O-rings should be replaced
each time the injector is removed from the
cylinder head.
• Note: Do not attempt to remove the oil
inlet O-ring. It is not replaceable. If the O-
ring is damaged, the injector must be
replaced. Do not pull on the wires while
working on the injector.
Injector Installation
• Lubricate the upper and lower O-rings on
the body of the injector. Place the hold-
down clamp lug into the notch of the
injector body. Lower the injector into the
bore and use a #40 Torx bit to tighten the
bolt to the specified torque. Install the
injector pass through connector into the
carrier, making sure that the connector
snaps in fully.
• Lubricate the internal O-ring at the top of
the injector.
• Install the rail over the injectors and start
the bolts by hand. Torque the rail bolts
using the proper sequence.
Case-to-Head Tube Installation
• If the tube does not pull out with the port
plug it will need to be removed after the rail
is removed using the Case-to-head Tube
Removal Tool (ZTSE4694). Before
installation, lubricate the O-rings on the
case-to-head tube and port plugs. Push
the port plug into the tube and insert into
the oil rail. Torque the port plug to
specification.
• Note: The O-rings are not serviceable.
Inspect the O-rings and replace the case-
to-head tube and port plug if the seals
are damaged.
