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. Lower the temperature of bearing cups (28) and (29) to -62° 10°C (-80° 50°F). Use insulated gloves to install bearing cups (28) and (29) into rear frame assembly (20). Make sure the bearing cones are properly seated. 2. Install O-ring seal (33) to spacer (34). Make sure that the sealing lip of lip seal (31) is facing toward the inside of cover (22).3. Install lip seal (31) and O-ring seal (32) to cover (22). Lubricate the seal lip with the lubricant that is being sealed. Ensure that 12 bolts (21) and the washers are installed in cover (22) prior to installing bearing cone (30).4. Position cover (22) on spacer (34). Install spacer (34), cover (22), 12 bolts (21) and the washers to oscillating hitch (35).5. Pack bearing cone (30) with grease prior to installation. Use two people and position bearing cone (30), as shown. The weight of bearing cone (30) is 40 kg (88 lb).6. Use two people to install the components of Tooling (A). The weight of Tooling (A) is 35 kg (77 lb).7. Attach a hoist and a suitable lifting sling to Tooling (B). Install Tooling (B), as shown. The weight of Tooling (B) is 29.5 kg (65 lb).8. Use Tooling (A) and Tooling (B) to install spacer (34), cover (22) and bearing cone (30). Ensure that O-ring seal (33) on spacer (34) seals against oscillating hitch (35). 9. Attach a hoist and suitable lifting chains to rear frame assembly (20), as shown. The weight of rear frame assembly (20) is 8450 kg (18 632 lb). Install rear frame assembly (20). 10. Pack bearing cone (27) with grease prior to installation.11. Install an M20 x 2.5 guide stud to the oscillating hitch to support bearing cone (27). Attach a hoist and a suitable lifting sling to bearing cone (27). Install bearing cone (27). The weight of bearing cone (27) is 40 kg (88 lb). 12. Install retainer (26) without the shims. Install six evenly spaced bolts (25) and the washers.13. Tighten six bolts (25) by an equal amount to a torque of 180 N*m (135 lb ft).14. Loosen six bolts (25). Retighten by an equal amount to a torque of 135 N*m (100 lb ft).15. Use a hoist to fully oscillate the hitch assembly. Repeat Step 14.16. Use Tooling (C) and measure the distance from the face of retainer (26) and the oscillating hitch. Measure through the three small holes in retainer (26). Find and record the average value of the three measurements. 17. Use Tooling (D) to measure the thickness of retainer (26). Measure next to the three small holes used
