To prevent damage when pressing the bearings into the rear hub, make sure that the bearing press adapters contact both the inner and outer races
of the bearing.
Install a new 61903 bearing into the drive side bearing bore of the hub
shell with the
orange
seal facing outward.
Slide the 6903 bearing adapter onto the threaded rod of the bearing
press tool. Insert the threaded rod through the drive side of the hub
shell and position the narrow end of the bearing adapter into the
center of the bearing.
Slide the second 6903 bearing adapter onto the threaded rod, and
position the adapter into the non-drive side hub shell bearing bore.
Thread the bearing press handle onto the threaded rod. Turn the
threaded handle clockwise to press the bearing into the drive side
bearing bore until it is hand tight.
Remove the bearing press tool.
N OT I C E
Do not overtighten the bearing.
Install the longer, drive side of the axle through the non-drive side of
the rear hub and through the drive side bearing.
