Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The valves have a hard surface finish. Grinding compound must not be used on the valves. Grinding compound will damage the hard surface finish of the valves.
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 Step 1.a through Step 1.e in order to inspect the components of the cylinder head assembly. Replace any components that are worn or damaged.
Inspect the cylinder head for wear and for damage. Refer to System Operation, Testing and Adjusting, "Cylinder Head Inspect" for the correct procedure.
Inspect the valve seats for wear and for damage. Refer to Specifications, "Cylinder Head Valves" for more information.
Inspect the valve guides for wear and for damage. Refer to Specifications, "Cylinder Head Valves" and System Operation, Testing and Adjusting, "Valve Guide - Inspect" for more information.
Inspect the valves for wear and for damage. Refer to Specifications, "Cylinder Head Valves" for more information.
Inspect the valve springs for damage and for the correct length. Refer to Specifications, "Cylinder Head Valves " for more information.

Lubricate the stems of valves (5) with clean engine oil. Install valves (5) in the appropriate positions in the cylinder head. Check the depth of the valves below the face of the cylinder head. Refer to System Operation, Testing and Adjusting, "Valve Depth - Inspect" for more information.
Use a suitable lifting device to turn over the cylinder head. The weight of the cylinder head is approximately 65 kg (143 lb). Note: Ensure that all of the valves remain in place.
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 valve stem seals (4).
Install valve spring (3) onto the cylinder head. Position valve spring retainer (2) on 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
