Checking Flatness of Cylinder Head Surface
1) Clean the surface of the cylinder head.
2) Place a straight edge on each of the cylinder head's four
sides and two diagonally as shown at the left to check
the straightness of the surface.
3) Insert a feeler gaulle between the straight edge and the
cylinder head surface.
4) The maximum thickness that can be inserted is the
amount of flatness.
5) If the measurement exceeds the allowable limit, correct
with a surface grinder.
• Do not place the straight edge on the combustion
