FILTER 5351677 - Caterpillar

Heat the cone evenly around its circumference. Do not stop the torch and heat the cone in one place. If the bearing cone is heated in any one place to a temperature above 120° C (248° F), its heat treatment will be destroyed, and a bearing failure is probable if it is used again.
26. Loosen hub (24) from hub (28) with tooling (E) until bearing is free. It is possible that the bearing cone will need to be heated with a torch. 27. Remove tooling (E). Remove bearing cone (27). 28. Install tooling (F) on hub (24). Fasten a hoist to tooling (F). Remove hub (24) from hub (28). The weight of the hub is 352 Kg (775 lb.). Turn the hub over. 29. Remove Duo-Cone seal (29) from the hub. 30. Remove bearing cup (31) from the hub with a punch and a hammer.31. Turn the hub over and remove bearing cup (30) from the hub with a punch and a hammer. 32. Remove Duo-Cone seal (32) from hub (28). Put identification on the seal for installation. 33. If necessary remove bearing cone (33) from the hub. 34. Remove lip-type seal (34) from the hub.Assemble Final Drives
1. Inspect all parts for damage and make replacements if needed. Make sure all parts are clean. 2. Install the lip type seal in the hub with tooling (D). The lip of the seal must be down as shown. 3. Heat bearing cone (33) to a maximum temperature of 135° C (275° F). Install bearing cone (33) on hub (28). Before installing any of the Duo-Cone seals, see Installation Of The Duo-Cone Floating Seals in this module. 4. Install Duo-Cone seal (32) with tool (G) as shown on the hub. 5. Lower the temperature of bearing cups (30) and (31). Install bearing cups (30) and (31) in hub (24). 6. Install Duo-Cone seal (29) in hub (24) with tool (G).
Do not put hub (24) on the Duo-Cone seal when the hub is turned over.
7. Turn hub (24) over. Install tooling (F) in the hub and fasten a hoist to the tooling. Put hub (24) in position on hub (28) as shown. 8. Heat bearing cone (27) to a maximum temperature of 135° C (275° F). Install bearing cone (27) on the hub. 9. Put tooling (H) in position while the bearing cone is still hot. Install retainer (20). Turn the hub while the bolts that hold the retainer are tightened to a torque of 135 15 N*m (100 11 lb.ft.). Let the bearing cone return to room temperature before the retainer and tooling (H) is removed. 10. Install tooling (A) on hub (26). Fasten a hoist to tooling (A). Put hub (26)
