1. Install the rubber toric sealing ring on the metal floating seal for each half of the Duo-Cone floating seal. The rubber seal and the metal ring that makes contact with it must be clean and dry. Put a small amount of SAE 30 oil on the outside surface of the metal seal ring that does not make contact with the rubber seal.2. Install one half of the Duo-Cone floating seal on the spindle with tool (A). 3. Install the inner bearing cone (1) on the spindle. 4. Lower the temperature of bearing cups (2) and install them in the wheel assembly. 5. Install brake disc (3) on the wheel assembly and tighten the bolts to a torque of 195 20 lb.ft. (265 25 N m).6. Install the other half of the Duo-Cone floating seal in the wheel assembly with tool (A). 7. Lower the temperature of bushing (4) and install it in the hub assembly (5).8. Install the outer bearing cone (6) on hub assembly (5) as shown.9. Fasten a hoist to the wheel assembly with tool (B). Put the wheel assembly in position on the spindle.
Do not remove the hoist and tool (B) until the nut that holds the wheel assembly in position is installed.
10. Install hub assembly (5) on the spindle. 11. Install ring gear (7) and the plates, bolts and locks that hold it to the hub assembly.12. Install the nut on the spindle. 13. Tighten the nut with tool (C) while the wheel is turned with an 8 in. (20.3 cm) long lb. in. (N m)
