2. Wheel Hub Greasing and Installation
It is recommended that hubs are dismantled, cleaned and repacked every year. Use the diagram and
following instructions for maintaining the wheel hubs. Whenever a worn or damaged seal is replaced
the bearing assembly should be cleaned and repacked with a good grade of wheel grease.
1. Using a grease packer, pack both roller bearings with a good grade of wheel grease. The
bearings should be thoroughly coated with grease. Spread grease on the outside of the bearing
with your gloved finger. Ensure that no dirt or filings contact the grease or the bearings.
2. Pack the inside of the hub with grease. Grease needs to cover complete surface area inside hub
but does not need to fill cavity.
3. Smear grease on both races.
4. Install the large bearing into the back of the hub and rotate the bearing several times.
5. Install the dust/grease seal using the right size seal driver. Spread a film of grease on the dust
seal rubber and on the axle where the seal fits.
6. Position the hub on the axle and firmly push into place then pull hub towards you about 1".
Slowly rotate hub while gently pushing the hub back onto the axle.
7. Check dust seal to ensure seal rubber is positioned correctly.
8. Install the small or outer bearing. .
9. Install the axle washer and castle nut on the axle.
