BEARING REPLACEMENT
Refer to the following table and figure for the parts and parts descriptions for the bearing replacement.
- Remove dust cap, cotterpin and spindle nut.
- Pull hub off spindle and remove washer and outer
bearing.
- Remove seal and inner bearing.
- Inspect seal and bearings for damage. Replace as
needed.
- Re pack bearings if they are in good condition. Rotate
bearings in their races a few times and remove any
excess grease.
NOTE: To prevent bearing damage, be sure that the
housing and spindle are free of dirt and metal
particles.
- Before installing the bearings in the housing, partially
fill the housing with grease. Do not completely fill the
housing with grease since this will cause churning of
the grease and will result in heat and eventual bearing
failure.
- Place the inner bearing and seal back in the hub and
slide over spindle.
- Insert outer bearing and washer. Tighten spindle nut
on spindle to set pre-load.
- Generally the pre-load can be set by tightening the
spindle nut until a ‘grabbing’ or resistance to turning
is felt in the housing. Once this is obtained back the
spindle nut off one notch and replace the cotterpin.
- Place a small amount of clean grease in the dust cap
and replace it.
