GEARCASE
BEARING AND SEAL INSTALLATION
Apply Needle Bearing grease to the needle bear-
ings and insert them into the bearing case (except
“S” Type).
Place the bearing on the installer tool with the let-
tered side of the bearing facing the top of the
gearcase. Use Needle Bearing grease to hold the
bearing on the tool.
IMPORTANT: The pinion bearing is tapered so
that, when installed correctly, its shape compen-
sates for stresses in the gearcase and allows full
bearing contact. Whenever a gearcase is disas-
sembled, the pinion bearing should be checked to
ensure that it has been installed with the lettering
facing up.
Insert the tool with the bearing into the gearcase.
Drive the bearing into the gearcase until the
washer on the tool contacts the spacer.
Remove the tool.
Position new O-ring on the pinion bearing retain-
ing screw. Apply Gasket Sealing Compound to O-
ring. Apply Nut Lock to screw threads. Install the
screw and torque to 60 to 84 in. lbs. (7 to 9.5
N·m).
Driveshaft Bearing Housing
Lightly apply Gasket Sealing Compound to a new
O-ring. Install the O-ring in top groove of the bear-
ing housing. Do not allow sealant in oil passage.
IMPORTANT: Do not install the O-ring in the
bearing housing’s bottom groove. The bottom
groove is an oil passage. Gearcase damage could
result.
Install new seals back to back in bearing housing
using Seal Installation Tool, P/N 330268. Apply
Gasket Sealing Compound to metal casings of the
seals before installing. Install inner seal with lip
facing toward bearing housing, then the outer seal
with lip facing away from bearing housing. Apply
Triple-Guard grease to seal lips.
