the thrust bearing and it should be inspected for pits, rust, scoring or discoloration due
to lack of lubricant. O-ring should be inspected for cuts or abrasions and replaced if
necessary.

should be inspected for pitting, rust or signs of discoloration (blueing) due to lack of
lubricant. If thrust roller bearing must be replaced, the bearing surfaces on the thrust
washer and propeller shaft where the thrust roller bearing rides should also be in-
spected for signs of wear.
