NOTE: The needle bearings in the reverse gear should not be removed unless damage
has been found. Inspect to ensure that all of the needles are present and in position.
Needles that have been dislodged may be snapped back into place as long as no damage
has occurred to the bearing cage.
4. Inspect the needle bearings on the inside of the reverse gear and the bearing surface
on the propeller shaft. If either the needle bearings or the bearing surface of the pro-
