PLATE 3305381 - Caterpillar

Start By:a. remove front tires and rims1. Place a suitable container under the front wheel spindle in order to collect oil from the spindle housing for storage or disposal. The capacity of the front spindle housing is .5 L (.50 qt) 2. Remove two bolts (1) and cover (2) from the back of the spindle housing. 3. Remove O-ring (3) from cover (2). Remove three bolts (4) and plate (5) from the spindle shaft. 4. Fasten Tool (A) and a hoist and attach to the spindle flange.5. Loosen bolt (6). Install Tool (B) under the head of bolt (6) and against the spindle shaft.6. Tighten the nut on Tool (B) in order to push wheel spindle (8) out of the wheel spindle housing. 7. Remove wheel spindle (8). Remove bearing (7). Remove Tool (B) and tighten bolt (6) to a torque of 700 27 N m (515 20 lb ft). 8. Remove bearing (9) from the spindle shaft with Tooling (C).9. Remove Duo-Cone seal (10) from wheel spindle (8). 10. Remove Duo-Cone seal (11) from the wheel spindle housing. Remove bearing cups (12) from the housing.11. Repeat Steps 1 through 10 for the removal of the other wheel spindle.Install Front Wheel Spindles
1. Insure that all surfaces of the wheel spindle and the wheel spindle housing are clean and free of any nicks or metal burrs. During installation of the wheel spindles, check the condition of all O-ring seals used in Duo-Cone seals and in covers that were removed. 2. Lower the temperature of bearing cups (12). Install bearing cups (12) in the wheel spindle housing.3. Make sure that Duo-Cone seal (11) is clean and dry. Make sure the surfaces of the housing that contact the Duo-Cone seal are also clean and dry. See the Duo-Cone seal story in this manual for further information. Install Duo-Cone seal (11) using Tool (B). 4. Make sure that Duo-Cone seal (10) is clean and dry. Make sure the surfaces of the spindle shaft that contact the Duo-Cone seal are also clean and dry. See the Duo-Cone seal story in this manual for further information. Install Duo-Cone seal (10) using Tool (B). 5. Heat bearing (9) to a temperature of 135°C (275°F) and install on the spindle shaft.6. Lower the temperature of wheel spindle (8). Heat bearing (7) to a temperature of 135°C (275°F).7. Install wheel spindle (8) in the housing.8. Install bearing (7) on the end of wheel spindle (8). 9. Install shims (not shown), cover (5), and three bolts (4). Tighten three bolts (4) evenly to pull wheel spindle (8) and bearing (7) in position. Tighten bolts (4) to a torque of 130 7 N m (96 5 lb ft).10. Check the amount of torque that is needed in order to turn the spindle assembly. The bearing preload can not exceed a rolling torque of 20 N m. Add or remove shims in order to obtain the correct rolling torque. 11. Install O-ring (3) on cover (2).
