CLEANING/INSPECTION - BEARING CARRIER
IMPORTANT: It is recommended that all seals and
O-rings be replaced (as a normal repair proce-
dure) to assure effective repair.
1. Clean bearing carrier assembly with solvent and
dry with compressed air.
CAUTION
DO NOT spin bearings dry with compressed air,
as this could cause bearing to score.
2. Bearing carrier propeller shaft needle bearing
condition is determined by propeller shaft
bearing surface condition. (See “Propeller Shaft
Inspection.”)
3. Inspect reverse gear to pinion gear wear pattern
(should be even and smooth). If not, replace
reverse gear and pinion gear.
4. Check clutch jaws on reverse gear for damage.
Replace reverse gear, if damage is found on
clutch jaws.
5. Apply light oil to reverse gear bearing. Rotate
reverse gear bearing while checking bearing for
rough spots and/or catches. Push in and pull out
on reverse gear to check for bearing side wear.
Replace bearing if any of the listed conditions
exist.
DISASSEMBLY- BEARING CARRIER
1. Remove and discard O-ring from between
bearing carrier and thrust washer.
2. If inspection of reverse gear or reverse gear
bearing determines that replacement of gear or
bearing is required, remove gear and bearing as
follows:
a. Position bearing carrier in a soft jaw vise.
b. Use Slide Hammer (91-34569A1) and
remove reverse gear.

c. If reverse gear bearing remains attached to
reverse gear, install Universal Puller Plate
(91-37241) and position puller plate, gear
and bearing on a press with gear side down.
Use a suitable mandrel and press gear out of
bearing.

d. If reverse gear bearing has remained in
bearing carrier, use slide hammer to remove
bearing in the same methods as was used to
remove reverse gear (Step “b”).
3. Propeller shaft oil seals can be removed by (a)
using a pry bar, or (b) pressing seals out when
propeller shaft needle bearing is pressed out of
bearing carrier.

NOTE: Unless propeller shaft needle bearing is
going to be replaced, do not use Step 2-b. High
Performance CLE, Sport Master and Torque Master
gearcases have a retaining ring between the 2nd
seal and the needle bearing. This retaining ring must
be removed before the needle bearing can be
removed from the bearing carrier.
