5.
Piston
a. If the tin-plate on the piston and the original grooves in the piston rings are
intact, it is an indication of very little wear.
b. Examine the piston for score marks, cracks, damaged ring groove lands or
indications of overheating. A piston with light score marks which can be
cleaned up may be reused. Any piston that has been severely scored or
overheated must be replaced. Indications of overheating or burned spots on
the piston may be the result of an obstruction in the connecting rod oil
passage.
c.
Replace the piston if cracks are found across the internal struts. Use the
magnetic particle inspection method for locating cracks in the piston.
