1. If previously removed, install the large snap ring into the housing groove.
Ensure that the snap ring is fully seated in the housing groove.
2. Install the outer bearing spacer from the top of the spindle housing. The
spacer should contact the large snap ring.
3. Use an arbor press to push the bearing cups into the top and bottom of the
spindle housing. The top bearing cup must contact the outer spacer that was
previously installed, and the bottom bearing cup must contact the snap ring.
Ensure that the assembly is correct by supporting the first bearing cup and
pressing the second bearing cup against it; refer to

4. Pack the bearing cones with grease. Apply a film of grease on the lips of the
oil seals and O-ring.
The bottom seal must have the lip facing out (down). This seal
installation allows grease to purge from the spindle during the
lubrication process.
5. Install the lower bearing cone and oil seal into the bottom of the spindle
housing.
