Wheel Bearing Maintenance –
Triple-Lip
Wheel bearing maintenance should be performed at the
beginning of every season of use. Check the wheel
bearings periodically for excessive end play. If needed,
adjust or replace them using the following procedure:
1. Place the frame on blocks or stands sufficient to lift
the tire clear of the ground.
2. Remove the tire.
3. Remove the hub cap, cotter pin, slotted nut and
washer.
4. Remove the hub. Clean and inspect the bearings and
hub cavity. Replace any worn or defective parts.
5. Repack the bearings using a high-quality wheel
bearing grease.
6. Slide the triple-lip seal onto the spindle. Do not install
the seal into the hub.
7. Slide the inner bearing cone and hub onto the
spindle.
8. Install the outer bearing cone, washer and slotted
nut.

there is a slight resistance to wheel rotation. Then,
back the slotted nut off one notch, until the wheel
rotates freely without end play.

in the hub.
The triple-lip seals should point away from the hub to
keep contaminants out and allow grease to pass
