CYLINDER HEAD

• Head diameter (D)

• Valve length (L)

• Valve margin (T)

Valve Seat

Measure the valve seats as follows.
• Seat angle (

α

)

• Contacting width (X)

• Seat outer diameter (D):

• Cylinder head seat recess diameter (D)

Valve Guide Clearance

1.

Measure diameter of valve stem with micrometer.

2.

Measure inner diameter of valve guide with inside micrometer.

3.

Calculate the valve guide clearance.
(Valve guide clearance) = (Valve guide inner diameter) – (Valve
stem diameter)

• If it exceeds the limit, replace and/or valve guide.
