Valve and valve spring installation
• Mount the spring retainer, valve guide oil seal.
• 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.
• Tap on the valve gently two or three times with a rubber hammer to make the valve and the valve
lock connect well.
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.
It is recommended to replace the valve guide oil seal with a new one.
When mounting, the twisting direction of the inner and outer springs must be opposite.
Be careful to not damage the valve.
