PLATE 5P2371 - Caterpillar

16G ShownUpper Hitch
(1) Center bearing in bore, leaving 12.7 0.5 mm (.50 .02 in) on a side.(2) Cool bearing down to -57° to -68°C (-70° to -90°F) before pressing into bore.(3) Lubricate sealing lip when installed. Tightening Procedure1. Install and finger tighten four bolts (4) in cover (5).2. Tighten two diagonally opposite bolts (4) to 35 N m (26 lb ft). Tighten the remaining two bolts (4) the same amount.3. Repeat the procedure in Step 2, tightening bolts (4) to 70 N m (50 lb ft).4. Repeat again the procedure in Step 2, tightening bolts (4) to a final torque of 100 15 N m (75 11 lb ft).Lower Hitch
Procedure To Install Shims (8)1. Install cap (6) without shims (8). Install four bolts (7) evenly spaced around cap (6) (leave a maximum of two bolt holes between each bolt for 16G).2. Tighten four bolts (7) to 35 N m (26 lb ft).3. Retighten four bolts (7) to 70 N m (50 lb ft).4. Retighten four bolts (7) to 90 7 N m (65 5 lb ft).5. Check to see that lower cap (10) is against frame (9) before continuing. If cap (10) is not flush, disassemble bearings (11), looking for interference.6. With cap (10) flush with frame (9), measure the gap between upper cap (6) and frame (9) at each bolt (7). The minimum measurement is the correct thickness for shims (8).7. Remove bolts (7) and cap (6).8. Install correct thickness for shims (8), found in Step 6. Install cap (6) and all bolts (7).9. With all bolts (7) installed, repeat Steps 2 and 3.10. Tighten four bolts (7) to 100 15 N m (75 11 lb ft) Procedure To Install Shims (12).1. Install plate (14) without shims (12). Install two bolts (13) 180° apart.2. Tighten bolts (13) to 135 14 N m (100 10 lb ft).3. Measure the gap between plate (14) and frame (15). Find the minimum measurement and subtract 0.25 mm (.010 in). This the correct thickness for shims (12).4. Remove bolts (13) and plate (14).5. Install correct thickness for shims (12), found in Step 3. Install plate (14) and four bolts (13).6. Tighten four bolts (13) to 200 25 N m (150 18 lb ft).
