VALVE AND VALVE SPRING

VALVE AND VALVE SPRING REMOVAL

• Remove the cylinder head.
• First remove the valve cotter with the valve compressor,
then remove the upper spring race, valve spring, lower
spring race, valve stem oil seal in turn. Remove the valve
from the other side.
The removed parts should be placed in order to
avoid confusion. It's better to place the intake valve
parts and exhaust valve parts separately.

VALVE AND VALVE SPRING INSPECTION

• Inspect to see if the valve is bent or burned.
• Inspect if the action is smooth between the valve and the valve guide.
• Measure the outer diameter of the valve stem.
• Measure the free length of the inner and outer valve spring.

Valve and valve spring installation

• Mount the spring retainer, valve guide oil seal.
It is recommended to replace the valve guide oil seal with a new one.
• After applying oil on the valve stem, mount it into the valve guide.
• Mount the inner and outer valve springs.
• Mount the valve locker with a spring compressor.
When mounting, the twisting direction of the inner and outer springs must be opposite.
• Tap on the valve gently two or three times with a rubber hammer to make the valve and the valve
lock connect well.
