Upper Hitch Assembly
(1) Shim. (2) Retainer plate. (3) Bolt and washer. (4) Seal. (5) Bolt and washer. (6) Cap. (7) Shim. (8) Cup. (9) Cone. (10) Cap. (11) Seal. (12) Space. (13) Pin. (14) Bolt and washer. (15) Shim. (16) Retainer plate.
Apply 5P-3931 Anti-Seize Compound on the bearing bores in the frame.
Lubricate the sealing lips on seals (4) and (11) with 5P-0960 Molybdenum Grease. Position seals (4) and (11), and press the seals into bearing caps (6) and (10).
Cool bearing cups (8) to a temperature of −62° 10°C (−80° 18°F).
Position lower bearing cap (10), and retain lower bearing cap (10) in place. Use a second technician in order to retain lower bearing cap (10) in place.
Install lower bearing cup (8) into the bore of the housing. Drive the bearing cup downward in order to ensure contact with lower bearing cap (10).
Lubricate bearing cones (9) with oil and install the bearing cones.
Install upper bearing cup (8). Drive the bearing cup downward in order to ensure light contact pressure on the bearing cones.
Install shim (7), upper bearing cap (6), and three bolts (5). Install the bolts so that the bolts are 120° away from each other. Tighten the bolts by an equal amount.
Adjust the rolling torque in order to rotate the bearing cones. As required, use shims (7) to attain the correct amount of rolling torque. The rolling torque should be not less than 14.7 N m (130 lb in). The rolling torque should not be greater than 32.8 N m (290 lb in).
Install 12 bolts (5). Tighten the bolts to a torque of 300 40 N m (220 30 lb ft). Procedure to Install the Upper Hitch Pin

(17) Retainer plate. (18) Bolt and washer. (19) Spacer. (20) Pin. (21) Retainer plate. (22) Shim. (23) Bolt and washer.
Install spacer (19) into lower bearing cap.
Use two eyebolts in order to connect retainer plate (17) to pin (20). Use two bolts (18) to align plate (17). Cool upper hitch pin (20) to −62° 10°C (−80° 18°F). Align the bores in the upper hitch. Then insert the pin into the bores. Permit hitch pin to warm to ambient temperature.
Use three equally spaced bolts (23) and attach lower retainer plate (21) to hitch pin (20). Tighten the bolts.
Measure the gap between the bottom of pin (20) and retainer plate (21).
Remove plate (21). Then reassemble retainer plate (21) with a measured amount of shims (22). Tighten twelve bolts (19). Tighten six bolts (23) to 530 70 N m (390 50 lb ft). Procedure to Assemble the Lower Hitch Bearings
