Driveshaft and Pinion Gear
REASSEMBLY/INSTALLATION
1. Apply a light coat of Quicksilver Super Duty Gear Lubricant on l.D. of driveshaft ta-
pered bearing.
2. Thread a used pinion nut onto end of driveshaft. Leave approximately 1/16 in. (1.6
mm) of nut threads exposed. Driveshaft threads MUST NOT extend beyond nut or
thread damage could result while pressing.
3. Place bearing over driveshaft.
4. Using an old driveshaft bearing inner race or other suitable mandrel (which applies
pressing force on center bearing race only), press bearing onto shaft until seated.

5. Position pinion gear in gear housing below driveshaft bore with teeth of pinion gear
meshed with teeth of reverse gear.
6. Insert driveshaft into driveshaft bore while holding pinion gear. Rotate driveshaft to
align and engage driveshaft splines with pinion gear splines. Continue to insert drive-
shaft into gear housing until driveshaft tapered bearing is against bearing race.
NOTE: It is recommended that after final pinion depth is obtained, a new pinion nut be
installed. Clean pinion nut threads with Loctite 7649 Primer before applying Loctite 271.
7. Place a small amount of Loctite 271 onto threads of pinion gear nut and install flat
washer and nut on driveshaft with flat side of nut away from pinion gear. Hand tighten
pinion nut.
8. Place shim(s) (retained from disassembly) into gear housing. If shim(s) were lost or
are not reusable (damaged), start with approximately 0.010 in. (0.254 mm).
