PLATE 2531307 - Caterpillar

30. Lubricate bearing cone (13) with clean oil.31. Install Tooling (B) to the pinion housing. Attach a hoist and suitable lifting slings to Tooling (B). Use the hoist to lower the pinion housing onto pinion shaft (10). The weight of the pinion housing is 81 kg (180 lb). 32. Heat bearing cone (12) to a maximum temperature of 135°C (275°F).33. Use insulated gloves to install bearing cone (12) on pinion shaft (10). Do not reset bearing cone (12) at this time. Allow the bearing cone to cool. Refer to Step 34 through 39 for the procedure to set the bearing load.34. Lubricate bearing cone (12) with clean oil. 35. Install washer (11) on pinion shaft (10). Retaining nut (9) may be reused if the collar was not cracked during removal or during restaking. Otherwise, use a new part for replacement.36. Install retaining nut (9) on pinion shaft (10). 37. Install Tooling (F) to the end of the pinion shaft.38. Use a torque wrench to slowly rotate pinion shaft (10). Check the rolling torque. The proper rolling torque of new bearings is 1.0 N*m to 1.7 N*m (9 lb inch to 15 lb inch). Reduce the rolling torque to 0.5 N*m to 0.85 N*m (4.5 lb inch to 7.5 lb inch) for machines with more than 100 hours of operation.39. Continue to tighten retaining nut (9) until the proper rolling torque is achieved. If the rolling torque exceeds the specifications, back off the retaining nut by 45 degrees. Reset the bearing in order to relieve the preload. Repeat Step 38 and 39 until the specified preload is achieved.
Completed Stake(H) The spherical radius of the tool for peening must be 7.5 to 8.0 mm (0.30 to 0.32 inch).(J) The acceptable angle of the tool for peening is 20 10 degrees.(K) The minimum length of the crimp is 4.4 mm (0.19 inch).(L) The minimum depth of the crimp is 2.5 mm (0.10 inch).(M) Top view. 40. Lock retaining nut (9) by peening the collar in the slot on pinion shaft (10). Before you stake the nut, make sure that the pinion shaft has zero end play. 41. Use Tooling (D) to install lip seal (8) in retainer (6). The sealing lip must be facing the inside of retainer (6).42. Install O-ring seal (7). Lubricate the O-ring seal with clean oil. 43. Install retainer (6) on the pinion housing. Install bolts (5). The torque for the bolts is 55 10 N*m (40 7 lb ft). 44. Attach a hoist and suitable lifting slings to differential and bevel gear (26). Install differential and bevel gear (26) in carrier (27). The combined weight of the differential and of the bevel gear is 272 kg (600 lb). 45. Lubricate bearing cup (25) with clean oil. Install bearing cup (25) in the carrier. Repeat for the other side. 46. Install bearing cap (22) and adjustment nut (23). Make sure that the adjustment nut can turn freely.47. Install bolts (24) and tighten to
