Assembly and Installation
NOTE: The unitized seal features a rubber
inner sleeve that is designed to seal and rotate
with the fork. This feature allows you to
reuse a fork with minor grooves.
2. Inspect the fork seal surface for grooves
• If you find grooves on the fork, use calibrators
to measure the groove diameters. If any
groove diameter measures less than the dimensions
shown in Figure 5.97, replace the
fork.

CAUTION
DO NOT INSTALL A POSE SEAL AFTER
YOU INSTALL A UNITIzED PINION SEAL. THE
USE OF A POSE SEAL WILL PREVENT
CORRECT SEATING OF THE UNITIzED PIN-
ION SEAL ON THE FORk AND CAN RESULT
IN LUBRICANT LEAkAGE AT THE SEAL.
POSE SEAL INSTALLATION IS RECOM-
MENDED ONLY FOR TRIPLE-LIP AND OTHER
PREVIOUS DESIGN SEALS.
Do not use thin metal wear sleeves to refresh
the fork surface. Wear sleeves pressed in the
fork can prevent correct seating of the pinion
seal, damage the pinion seal assembly and can
cause the seal to leak.
3. Before install the fork, lightly lubricate the
seal track in the fork of the joint with axle oil.
4. Align the fork splines with the shaft splines.
Slide the fork over the shaft spline.
