NOTE: The needle bearing 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. The
needles may have become dislodged while removing the gear from the propeller shaft
(and/or while removing the propeller shaft assembly from the gear housing). They 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-
peller shaft is pitted, grooved, scored, worn unevenly, discolored from overheating,
or has embedded particles, replace the propeller shaft and remove and replace the
needle bearing in the reverse gear as outlined in the next section.

REVERSE GEAR ASSEMBLY - COMPONENT DISASSEMBLY
NOTE: Reverse gear can only be removed from gear housing after drive shaft and pinion
gear have been removed.
NOTE: Complete the instructions in this section only if the needle bearing in the gear has
been found to be defective and the reverse gear is to be reused. Bearings that have be-
come dislodged may be snapped back into position. If this is the only problem that exists
it is not necessary to replace the needle bearing.
1. Replace bearing if it is rusted or does not roll freely.
2. Press the reverse gear needle bearing out using a suitable mandrel.
