Driveshaft and Pinion Gear
REASSEMBLY/INSTALLATION
1. Apply a light coat of Quicksilver Super Duty Gear
Lubricant on l.D. of driveshaft tapered bearing.
Sport Master only - Apply High Pressure
Grease (such as Chicago Manufacturing and
Distributing Lube #3) to the I.D. of both bearings.
2. Thread a used pinion nut onto end of driveshaft.
Leave approximately 1/16″ (2mm) of nut threads
exposed. Driveshaft threads MUST NOT extend
beyond nut or thread damage could result while
pressing.
3. Place bearing over driveshaft.
Sport Master only - Both bearings can be
installed on the driveshaft in one operation. Place
the smaller bottom bearing over the driveshaft
with the numbers on the bearing facing the top of
the shaft. Place the larger top bearing exactly
opposite by having the numbers facing the pinion
end of the shaft. While holding bearings in place,
invert the driveshaft and place assembly in a
press.
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.
