Note: Do not remove the quill tube. This action will reduce the risk of contamination to the system.
Fully loosen quill tube nut (1). Pull quill tube (1) out of the bore until you see O-ring seal (2). This action will ensure that the injector does not contact the quill tube during removal. At this time, inspect O-ring seal (2) for wear or for damage. Replace the O-ring seal if necessary.

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.
