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: Install the upper seal pack first. Then install the middle seal pack. Finally, install the bottom O-Ring Seal.
Both the 149-2955 Seal Protector (A) and the 149-2956 Seal Installer (B) should be used when you are installing the upper high-pressure seals.Note: New seals should be installed after each removal of the injector from the engine.
Lubricate the O-Ring seals and the sleeve bore of the injector sparingly with clean engine oil.Note: Proper installation of the injector is important. Damage to the upper high-pressure seals can cause excessive oil leakage under the valve cover. Damage to the upper high-pressure seals may cause the engine not to start due to a low actuation pressure. Damage to the lower high-pressure seals may allow high-pressure oil to leak into the fuel supply passage. Damage to the lower-pressure seals will result in excessive oil consumption.

Six 159-0288 Deflectors and six 8T-2396 Bolts are required for each engine. These new deflectors and bolts replace the former 6V-8653 Bolts .

(C) 152-1057 Fuel Injector Installer
Carefully install the injector into the injector bore. If access permits you to seat the injector, push the injector straight down on top of the injectors solenoid by hand until the injector is firmly seated in the injector bore. Pushing hard enough to compress the injector seals may be difficult. If the injector cannot be seated by hand, use a 152-1057 Fuel Injector Installer (C) . Note: Do NOT pry on the top of the injector with another tool. Do NOT strike the injector with a hammer. Damage to the injector will result. Damage to the injector that is due to improper installation is not a warrantable failure.
