D4E TRACTOR POWER TRAIN Caterpillar


Adjustment Of Final Drive Bearings

Usage:

Put a 4 to 5 ft. (1.2 to 1.5 m) long bar between the sprocket and roller frame. Put side force at front and back of sprocket to test for loose sprocket hub bearings. The machine should be on smooth ground with no objects under the track that would put force against sprocket.

If bearing adjustment is needed, complete the steps that follow:

Use the 6V4032 Adapter Plate and 6V82 Tool Arrangement to adjust the preload of the final drive bearings.

1. Raise the tractor off the ground and loosen the track adjustment.

2. Remove dirt guard (1) and lock (2).

3. Remove cap (6) and lock (4). Check retainer nut (3) for tightness. To loosen adjusting nut (5) turn it one or two turns in a clockwise direction. Tighten the retainer nut (3) to a torque of 350 ± 50 lb. ft. (470 ± 70 N·m).

4. Use three 1/2-13 × 11/2" bolts to fasten the 6V4032 Adapter to the bearing support.

5. Use three 1/2-13 × 43/4" bolts through the holes in the 5P8632 Trunnion Assembly and three 5P8634 Spacers to fasten the trunnion assembly to the adapter.

6. Use the driver assembly to adjust the preload on the bearings.

7. While the sprocket is turned, tighten the adjusting nut to a torque of 1600 lb. ft. (2160 N·m). Turn the nut in a counterclockwise direction to tighten.

8. Loosen the adjusting nut to a torque that is below 350 lb. ft. (470 N·m).

9. Tighten the adjusting nut to a torque of 350 lb. ft. (470 N·m). Put a mark on the adjusting nut and on the holder assembly. Put a second mark on the holder 3" (76 mm) to the left of the first mark.

10. To preload the bearings, tighten the adjusting nut until the mark on the nut is in alignment with the second mark on the holder.

11. Continue to tighten the nut to the next notch if the lock can not be installed.

12. Remove the tooling.

13. Install lock (2), dirt guard (1), lock (4), and cap (6).

14. Lower the tractor to the ground.

15. Adjust the track.
