Usage:
NOTE: Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement.
1. Use the proper equipment to handle bushing (16). Lower the temperature of bushing (16). Install bushing (16) in hub (8).
2. Use the proper equipment to handle bearing cone (15). Heat bearing cone (15) to a maximum temperature of 135 °C (275 °F). Install bearing cone (15) on hub (8).
3. Use a hoist and a suitable lifting sling to carefully install hub (8) in ring gear (9). The weight of the hub is 32 Kg (70 lb).
4. Install retaining ring (14) in ring gear (9).
5. Install three bolts (13) and the washers in hub (8). Tighten the bolts to a torque of 30 ± 7 N·m (22 ± 5 lb ft).
6. Use the proper equipment to handle bearing cups (11) and (12). Lower the temperature of bearing cups (11) and (12). Install bearing cups (11) and (12) in wheel assembly (4). Apply clean lubricant to bearing cup (12).
7. Use Tooling (D) to install Duo-Cone seal (10) in wheel assembly (4). Refer to Disassembly and Assembly, "Duo-Cone Conventional Seals - Install" for the proper procedure.
8. Lightly lubricate the contacting surface of Duo-Cone seal (10).
9. Use the following procedure to install Tooling (B) in the hole of hub (8):
a. Place the lifting sling in the hole of hub (8).
b. Install the bolt between the sling and the hole.
c. Fasten the sling to the bolt by tying the sling around the bolt, as shown. This will prevent the bolt from moving during the installation of hub (8).
10. Repeat Steps 9.a through 9.c in order to install Tooling (B) in the two remaining holes.
11. Attach a hoist to the lifting slings. Use the hoist to carefully install hub (8) and ring gear (9) in wheel assembly (4). The weight of the hub and the ring gear as a unit is 68 Kg (150 lb).
12. Use Tooling (D) to install Duo-Cone seal (7) in wheel assembly (4). Refer to Disassembly and Assembly, "Duo-Cone Conventional Seals - Install" for the proper procedure.
13. Lightly lubricate the contacting surface of Duo-Cone seal (7).
14. Install bearing cone (6) on spindle assembly (5). Bearing cone (6) is a slip fit to the spindle.
15. Install Tooling (A) to wheel assembly (4), as shown. Attach a hoist and suitable lifting slings to Tooling (A).
16. Use the hoist to carefully install wheel assembly (4) to spindle assembly (5). The weight of the wheel assembly is 127 Kg (280 lb).
NOTE: Steps 17 through 29 are for the proper wheel bearing adjustment.
17. Use an outside micrometer to measure the thickness of retainer plate (2) at each of the three small gauge holes. Average the three measurements and record the result.
18. Install retainer plate (2) without shims. Apply oil on threads of three bolts (1) and install the bolts on retainer plate (2). The three bolts must be separated by 120 degrees.
19. Tighten three bolts (1) to a torque of 115 ± 15 N·m (85 ± 10 lb ft).
20. Rotate the wheel by 360 degrees. Check the bolts and tighten the bolts again, if necessary.
21. Loosen bolts (1). Rotate the wheel by 360 degrees in order to unload the bearings.
22. Tighten three bolts (1) to torque of 20 ± 7 N·m (15 ± 5 lb ft).
23. Rotate the wheel by 360 degrees, check the bolts and tighten the bolts again, if necessary.
24. Use Tooling (C) to measure the depth through the three small gauge holes of retainer plate (2). Average the three measurements and record the result.
25. Subtract the average thickness of the retainer plate from the average depth. Refer to Steps 17 and 24. The difference is the gap between the end of the spindle and retainer plate (2). This gap is the required thickness of shims.
26. Use Tooling (C) to measure the shim pack. The thickness of the shim pack must be within 0.025 mm (.001 inch) of the required thickness of shims.
27. Remove bolts (1) and retainer plate (2).
28. Install the required number of shims (3).
29. Install retainer plate (2) and ten bolts (1). Tighten the bolts to a torque of 125 ± 20 N·m (90 ± 15 lb ft) plus an additional 120 degrees ± 10 degrees.
End By:
a. Install the final drive, the brake and the wheel. Refer to Disassembly and Assembly, "Final Drive, Brake and Wheel - Install" for the machine that is being serviced.
