1. Check the condition of all O-ring seals used in the wheel assembly and wheel brake assembly. If any of the seals are worn or damaged, use new parts for replacement. 2. Heat bearing cone (1) to a maximum temperature of 135°C (275°F). Install the bearing cone on the hub. Be sure the bearing cone makes contact with the shoulder on the hub. 3. Turn the hub over. Lower the temperature of bushing (2), and install it in the hub. Be sure the bushing is installed below the outside surface of the hub. 4. Lower the temperature of bearing cup (3). Install the bearing cup in the wheel assembly as shown. Be sure the bearing cup makes contact with the counterbore in the wheel assembly. 5. Turn the wheel assembly over. Lower the temperature of bearing cup (4). Install the bearing cup in the wheel assembly as shown. Be sure the bearing cup makes contact with the counterbore in the wheel assembly. 6. Fasten the hub assembly to tooling (A) as shown.7. Fasten lifting straps and a hoist to wheel assembly (5) as shown. Put the wheel assembly in position on the hub assembly.
