Typical ExampleNote: Do not damage the unit injector during removal. Side loading may damage to the unit injector.
Position Tooling (A) under unit injector clamp (6) . Carefully remove unit injector (4) from the cylinder head.Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Evacuate as much fuel and oil as possible from the cylinder head before installing the unit injector. Several evacuations may be necessary. Use Tooling (C) to remove the fuel and oil from the cylinder.Note: Tooling (F) is available to clean loose material from the sleeve bore and the cylinder.
Clean the carbon from the sleeve, the sleeve bore, and the end of the unit injector. Clean the carbon from the seat area that is inside of the cylinder head. A fine grade of Tooling (B) is preferred. Clean the carbon from the cylinder head. If the sleeve of the unit injector has been removed, use Tooling (D) to remove only carbon from the surface of the sleeve. If the sleeve of the unit injector is installed, use Tooling (E) to clean the carbon deposit from the inside of the sleeve.The following procedure is the preferred method of cleaning the sleeve bore.Place a 38 mm (1.5 inch) square piece of Scotch Brite material on the end of Tooling (F) . Twist Tooling (F) with Tooling (H) against the lower surface of the sleeve bore.The surface should be cleaned until the surface is smooth and shiny. The entire sleeve bore should be cleaned in order to remove any loose carbon particles.Note: Tooling (G) is available to clean loose material from the sleeve bore and the cylinder.
The correct procedures and tooling specifications must always be used. Failure to follow any of the procedures may result in damage, malfunction, or possible engine failure.

Note: Replace the O-ring seals on the injector.
Install O-ring seal (9) and O-ring seal (10) on unit injector (4) . Lubricate O-ring seal (9) , O-ring seal (10) , and the sleeve bore of the unit injector sparingly with clean engine oil.
Record the serial number for the injector and the injector confirmation code. When you install a new unit injector, the E-Trim value must be programmed into the Engine Control Module. For more information, refer to Troubleshooting, "Injector Trim File - Install".

Note: Verify quill tube (1) is positioned out of the bore enough to see O-ring seal (2) . This action will ensure that the injector does not contact the quill tube during installation.
Place unit injector (4) into the bore. Make sure that the key (7) for the unit injector fits into slot (8) in the cylinder head.

Note: Use new socket head bolt (5) .
Position unit injector clamp (6) with the label "C9" in the up position. Install socket head bolt (5) into unit injector clamp (6) . Tighten socket head bolt (5) to a torque of 28 3 N m (21 2 lb ft) in order to secure unit injector (4) .
