Driveshaft and Pinion Gear
REASSEMBLY/INSTALLATION
1. Apply a light coat of Quicksilver Super Duty Gear Lubricant on l.D. of driveshaft
tapered bearing.
2. Thread a used pinion nut onto end of driveshaft. Leave approximately 1/16 in. (2 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.
7. Apply Loctite 271 to threads of pinion gear nut and install flat washer and nut on drive-
shaft with flat side of nut away from pinion gear.
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).
