Rear Seal Installation
Apply Gasket Sealing Compound to metal casings
of the seals before installing.
Use Seal Installation Tool to install new seals back
to back in bearing housing.
Seal Installation Tool:
• P/N 326551 – “S2” type
• P/N 354056 – “O”, “L2”, and “M2” type
Install inner seal with lip facing toward the bearing
housing, then outer seal with lip facing away from
the bearing housing.
Apply Triple-Guard grease to seal lips.
DRIVESHAFT SHIMMING
If a new pinion gear is needed,
replace gear set before shimming.
Pinion gear backlash is achieved by using shims
between the driveshaft bearing housing and the
thrust washer. When installing a new thrust bear-
ing or washer, bearing housing, pinion, or drive-
shaft, it is necessary to properly shim the
assembly to restore factory clearance.
Use Driveshaft Shimming Tool, P/N 5005925.
Shim gauge bars are precision made and should
be handled carefully. The length of each bar is
stamped near the part number. This dimension is
0.020 in. (0.508 mm) shorter than the actual
shimmed length of the driveshaft.
“S2” TYPE GEARCASE
IMPORTANT: Clean pinion and driveshaft
before assembly. Replace any damaged parts.
Assemble the driveshaft bearing housing, thrust
washer, thrust bearing, and pinion onto the drive-
shaft. Install shimming screw, P/N 352878 and
tighten to a torque of 47 to 51 ft. lbs. (64 to 69
N·m).
IMPORTANT: The original pinion screw is NOT
used for shimming, but is used in final assembly.
Use Shimming Screw, P/N 352878 (service tool)
for shimming procedure.
