HARNESS AS-SENSOR 2431552 - Caterpillar

Start By:a. remove final drivesb. remove wheel brakes 1. Remove lockwire, bolts (2) and lock (1).2. Fasten a hoist to the wheel.3. Remove nut from wheel with tool (A). 4. Remove the hub (3) from the wheel. Weight is 29 kg (65 lb). 5. Remove wheel (4). Weight is 82 kg (180 lb). 6. Remove Duo-Cone seal (5) and retainer from the wheel. The seal retainer must be removed evenly or damage to retainer will be the result.7. Remove inner bearing cone (6) from wheel. 8. Remove bolts (7), locks and plates (8) that hold ring gear to the hub.9. Remove the ring gear (10) from the hub (9). 10. Install four 3/8"-16 NC, 2 in. long bolts (11) in the hub (9).11. Remove bearing cone as bolts (11) are tightened. 12. Remove bushing (12) with tooling (B). 13. Remove bearings cups (13) with a hammer and punch.Install Wheel Assembly
1. Install the bearing cups (1) in the wheel.2. Install inner bearing cone and seal retainer. 3. The rubber seal and the metal ring that makes contact with it must be clean and dry. Put a small amount of SAE 30 oil on the outside surface of the metal seal ring that does not make contact with the rubber seal. Install the Duo-cone seal in the wheel with tool (A). 4. Install the bushing in the hub with tooling (B).5. Put the bearing cone of the hub in oil with a temperature of 135°C (275°F). Install the bearing cone on the hub. 6. Put the hub (2) in position on the ring gear (3) and install the plates, locks and bolts. 7. Put the wheel (4) in position on the spindle with a hoist. 8. Install hub (5) in the wheel. 9. Install nut (6) on the spindle. 10. Tighten nut with tool (C) while the wheel is turned with an 203 mm (8 in) long N m (lb in) 9S7354 Torque Wrench. The torque must be 8.5 2.8 N m (75 25 lb in).For other lb in. torque wrenches, the correct torque value can be found with this formula.C = A × TA + B"C" is the torque wrench indication"A" is the length of the torque wrench"B" is the distance from the center of the wheel to the wheel stud"T" is torque on bearings [T = 160 50 lb in. (18.1 5.6 N m)]. The torque wrench must be installed on wheel nut so it is in line with the center of the wheel as shown.11. Turn wheel slowly at a constant speed for one or two turns to check torque value after adjustment has been made.12. Install lock of nut. Tighten nut more if needed to get lock in alignment with bolt holes. Install bolts and lockwire.End By:a. install final drivesb. install wheel brakes
