Disassembly and Assembly Section
a. Ensure that harness assembly (4) for the
electronic unit injectors and the bore in valve
mechanism cover base (8) are clean and
free from damage. Replace any damaged
components.
b. Use Tooling (D) to lubricate a new O-ring
seal. Install new O-ring seal (6) onto harness
assembly (4) for the electronic unit injectors.
c. From the inside of valve mechanism cover
base (8), push harness assembly (4) into the
valve mechanism cover base.
d. Use Tooling (A ) to install circlip (5).
e. Connect plug (7) to harness assembly (4) for
the electronic unit injectors.
f. Use a deep socket to install connections (1) to
electronic unit injectors (2). Use Tooling (E) to
tighten the connections to a torque of 2.4 N·m
(21 lb in).
g. Install a new cable strap (3).
Note: Ensure that cable ties to OE speci fi cation are
used.

Start By:
a. Remove the cylinder head. Refer to Disassembly
and Assembly, “Cylinder Head - Remove”.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
1. Clean the bottom mating surface of the cylinder
head. Check the depth of the valves below the
face of the cylinder head before the valve springs
are removed. Refer to Speci fi cations, “Cylinder
Head Valves” for the correct dimensions.
2. Place a temporary identi fi cation mark on the
heads of the valves in order to identify the correct
position.
Note: Inlet valves have a recess in the center of the
head.
3. Use a suitable lifting device to position the cylinder
head with the valve springs upward. The weight of
the cylinder head is approximately 65 kg (143 lb).
Note: Ensure that the cylinder head is kept on a
clean, soft surface in order to prevent damage to the
machined face.
Personal injury can result from being struck by
parts propelled by a released spring force.
Make sure to wear all necessary protective equip-
ment.
Follow the recommended procedure and use all
recommended tooling to release the spring force.
