Inspect steel piston body. If any galling is apparent or if any irregularities can be felt
with the fingernail, the piston must be discarded. (Refer to fig. 3-35.) If damage is apparent, check the
corresponding block assembly bore (30, fig. 3-4) for similar damage. Inspect piston return plate (32) for
heat discoloration or cracks. Check for flatness. If discolored, cracked, or distorted, replace with a new
return plate. (Refer to fig. 3-36.)
