CYLINDER HEAD / VALVE

STEM SEAL

VALVE

SPRING

RETAINER

COTTER

NARROW PITCH

●

After cutting the valve seat, apply lapping compound
to the valve face, and insert the valve with a valve
guide reamer.

CYLINDER HEAD ASSEMBLY

●

Install new stem seals.

●

Lubricate each valve stem with molybdenum disulfide
grease and insert the valve into the valve guide.

●

Install the spring seats, valve springs and retainers.

●

Compress the valve springs with the valve spring
compressor and install the valve cotters.

TOOL : VALVE SPRING COMPRESSOR

Do not excessively press and turn the valve to set it as
it may cause damage. Gently strike and set the valve.

The seat surface may become worn on one side if the
valve is set in the same position. Turn the valve slightly
when setting it.

Take precautions not to allow compound to get into the
clearance between the stem and guide while the valve
is being set.

Replace the stem seals with new ones whenever a stem
seal is removed.

For valve spring with varying pitch, install the valve
springs with the narrow pitch end facing down.

Turning a valve too fast can damage the stem seals.

Compressing the valve spring more than necessary
when installing the valve cotters may cause loss of
valve spring tension.
