NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
1. Clean all components of the cylinder head
assembly. Ensure that all ports, all coolant
passages, and all lubrication passages in the
cylinder head are free from debris. Follow Steps 1.
a through 1.e in order to inspect the components
of the cylinder head assembly. Replace any
components that are worn or damaged.
a. Inspect the cylinder head for wear and for
damage. Refer to Systems Operation, Testing
and Adjusting, “Cylinder Head Inspect”.
b. Inspect the valve seats for wear and for
damage. Refer to Specifications, “Cylinder Head
Valves” for further information.
c. Inspect the valve guides for wear and for
damage. Refer to Specifications, “Cylinder Head
Valves” and Systems Operation, Testing and
Adjusting, “Valve Guide - Inspect” for further
information.
d. Inspect the valves for wear and for damage.
Refer to Specifications, “Cylinder Head Valves”.
e. Inspect the valve springs for the correct length.
Refer to Specifications, “Cylinder Head Valves”.

2. Lubricate the stems of valves (6) with clean engine
oil. Install valves (6) in the appropriate positions in
the cylinder head. Check the depth of the valves
below the face of the cylinder head. Refer to
Systems Operation, Testing and Adjusting, “Valve
Depth - Inspect” for more information.
3. Use a suitable lifting device to carefully turn over
the cylinder head. The weight of the cylinder head
is approximately 56 kg (125 lb).
Note: Ensure that all of the valves remain in place.
4. Install valve spring seats (5).
5. Use Tooling (B) in order to install new valve stem
seals (4) onto each of the valve guides.
Note: The outer face of the valve guides must be
clean and dry before installing the valve stem seals.
6. Install valve spring (3) onto the cylinder head.
Position valve spring retainer (2) onto valve spring
(3).
Personal injury can result from being struck by
parts propelled by a released spring force.
Make sure to wear all necessary protective
equipment.
Follow the recommended procedure and use all
recommended tooling to release the spring force.
