Forward Gear Bearing Race
INSTALLATION
1. Place shim(s) (retained from disassembly) into gear housing. If shim(s) were lost or
a new gear housing is being used, start with approximately 0.010 in. (0.254 mm).
2. Apply a light coat of Quicksilver Super Duty Gear Lubricant to forward gear bearing
race bore in gear housing.
3. Position tapered bearing race squarely over bearing bore in front portion of gear
housing.
4. Place Bearing Driver Cup (91-87120) over tapered bearing race.
NOTE: A used propeller shaft is recommended for use in Step 5. If it is necessary,
however, to use the propeller shaft that will be installed in gear housing, the propeller
shaft must be disassembled. (Refer to “Propeller Shaft Disassembly,” preceding.)
5. Place propeller shaft into hole in center of bearing driver cup.
6. Install bearing carrier assembly over propeller shaft and lower it into gear housing.
Bearing carrier acts as a pilot to assure proper bearing race alignment.
7. Thread a nut onto propeller shaft to protect propeller shaft threads.
8. Use a mallet to drive propeller shaft against bearing driver cup until tapered bearing
race is seated against shim(s).
