Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g01130613
Use Tooling (B) to clean the bore for the electronic unit injector in the cylinder head. Hold Tooling (B) with Tooling (C). Rotate Tooling (B) against Surface (X) of the bore. Continue cleaning until Surface (X) is smooth and shiny.
Use Tooling (D) to remove the fuel from the cylinder. Evacuate as much fuel as possible from the cylinder before installing the electronic unit injector. Several evacuations may be necessary.
Illustration 2 g01130615
Install O-ring seal (6) and O-ring seal (7) on the electronic unit injector.
Apply Tooling (E) to the bore of the cylinder head for the electronic unit injector.
When an electronic unit injector is replaced, the new electronic injector code must be programmed into the engine's personality module software by using the calibration menu on the Electronic Service Tool. If the new electronic injector code is not entered, the characteristics of the previous electronic unit injector is assumed.If it is not possible to immediately reprogram the electronic injector code into the personality module software, the engine will not be severely harmed. The new electronic injector code should be reprogrammed as quickly as possible in order to optimize engine performance.
Position electronic unit injector (5) into the original location in the cylinder head. Center the solenoid between the valve springs. Press the electronic unit injector into the cylinder head. Do not strike the electronic unit injector.
Illustration 3 g01130566
Install plug (4) in the cylinder head.
Install electronic unit injector clamp (3) and bolt (1). Tighten bolt (1) in order to seat electronic unit injector (5) in the cylinder head. Do not strike the electronic unit injector. Tighten bolt (1) to a torque of 65 7 N m (48 5 lb ft).
Connect harness assembly (2). Tighten the terminal nuts to a torque of 2.5 0.25 N m (22 2 lb in).End By:
Install the rocker shaft assembly. Refer to Disassembly and Assembly, "Rocker Shaft and Pushrod - Install".
