“O” Type Gearcases
IMPORTANT: Spacers are different sizes and
cannot be interchanged.
Apply Needle Bearing grease to the needle bear-
ings and insert them into the bearing case (“O”
Type gearcases).
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 tighten to a torque of 60 to 84 in. lbs. (7
to 9.5 N·m).
Shift Housing Disassembly
IMPORTANT: The shift housing and bearing
are serviced as an assembly. If either are worn or
damaged, replace the complete assembly.
Insert a suitable tool under one end of the clutch
dog spring and remove it from its groove by
unwrapping it from around the clutch dog. Dis-
card the spring.
