a. Ensure that harness assembly (4) for the
electronic uni
t injectors and the bore in valve
mechanism cover base (8) are clean and
free from damage. Replace any damaged
components.
b. UseTooling(D)tolubricateanewO-ring
seal. Instal
l new O-ring seal (6) onto harness
assembly (4) for the electronic unit injectors.
c. From the insi
de of valve mechanism cover
base (8), push harness assembly (4) into the
valve mechanism cover base.
d. UseTooling(A)toinstallcirclip(5).
e. Connect plug
(7) to harness assembly (4) for
the electronic unit injectors.
f. Useadeepsoc
ket to install connections (1) to

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 Specifications, “Cylinder
Head Valves” for the correct dimensions.
2. Place a temporary identification 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 t he recommended procedure and use all
recommended tooling to release the spring force.
