NOTE:
Refer to the appropriate ENGINE article for the specification.
- Using a straightedge and a feeler gauge, inspect the cylinder head for flatness in the sequence shown.
NOTE:
Make sure all cylinder head surfaces are clear of any gasket material, RTV, oil and coolant. The cylinder head surface must be clean and dry before running a flatness check.
NOTE:
Use a straightedge that is calibrated by the manufacturer to be flat within 0.005 mm (0.0002 in) per running foot of length, such as Snap-On® GA438A or equivalent. For example, if the straightedge is 61 cm (24 in) long, the machined edge must be flat within 0.010 mm (0.0004 in) from end to end.
