NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Note: The installation procedure is identical for the
two cylinder, the three cylinder and the four cylinder
engines. The I
llustrations show a four cylinder engine.
1. Clean all components of the cylinder head
assembly. En
sure 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 Adjusti
ng, “Cylinder Head Inspect”.
b. Inspect the valve seats for wear and for
damage. Ref
er to Specifications, “Cylinder
Head Valves” for further information.
c. Inspect th
e valve guides for wear and for
damage. Refer to Specifications, “Cylinder
Head Valves” and Systems Operation, Testing
and Adjust
