Illustration 5 g01342487 - Position valve mechanism cover base (7) on the cylinder head. Tighten isolated screws (9) to a torque of
9 N·m (79 lb in) in the sequence that is shown in illustration 5.Show/hide tableIllustration 6 g01342484 - If necessary, install the harness assemblies for the electronic unit injectors. Follow steps 5.a through 5.h in order to install the harness assemblies for the electronic unit injectors.
- Ensure that harness assembly (4) and the bore in valve mechanism cover base (7) are clean and free from damage. Replace any damaged components.
- Use Tooling (B) to lubricate a new O-ring seal (8). Install the new O-ring seal (8) onto harness assembly (4).
- From the inside of valve mechanism cover base (7), push harness assembly (4) into valve mechanism cover base (7).
- Use Tooling (A) to install circlip (5).
- Connect plug (6) to harness assembly (4).
- Use a deep socket to connect harness (4) to electronic unit injectors (2). Use Tooling (C) to tighten connectors (1) to a torque of
2.4 N·m (21 lb in) . - Install a new cable strap (3) to harness assembly (4).
Note: Ensure that cable strap to OE specification.
- Repeat steps 5.a through 5.g for remaining harness assemblies (4).
End By:
- Install new fuel injection lines. Refer to Disassembly and Assembly, "Fuel Injection Lines - Install".
- Install the valve mechanism cover. Refer to Disassembly and Assembly, "Valve Mechanism Cover - Remove and Install".
