INSPECTION
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 inspec-
tion method for locating cracks in the piston.
