It is necessary to check play of final drive flanged axle bearings on the completion of the first 100 hours of operation, every 500 hours and at the end of each harvest season.

When checking the adjustment, it is necessary to remove the front wheel of the machine and push the flanged axle (1) up and down.

If there is play, have the bearings adjusted by your John Deere dealer or, if you possess the suitable tools, adjust as follows:

2. Remove final drive from machine.

3. Remove bearing support (3) and shaft seal (5) of drive pinion (4).

4. Install drive pinion bearing support (3), without shaft seal (5). Take care to assemble the same gaskets (6). Tighten bolts (7) of bearing support (3) to 60 N.m (44 lb-ft).

5. Remove flanged axle nut cap (8) and locking pin (10).

6. Check nut (9) torque, it should be 100 N.m (73.75 lb-ft).

7. Rotate flanged axle (1) several times. Using an aluminum hammer, lightly tap both sides of flanged axle to seat bearings.

8. Check flanged axle (1) rolling drag torque through nut (9), it should be 7 to 13 N.m (5 to 10 lb-ft). Adjust castle nut, if necessary.

NOTE: If necessary loosen nut (9). Make sure to loosen bearings also. If necessary use aluminum hammer and lightly tap both sides of flanged axle to seat bearing cups.

9. Repeat this procedure until the correct torque is obtained.

10. Tighten castle nut (9) until one of the grooves aligns with the bore on the shaft end (1) and install the locking pin (10). Seal and install cap (8).

11. Remove drive pinion bearing support (3) and install shaft seal (5).

12. Install drive pinion bearing support (3), taking care to use the same gasket (6). Tighten bolts (7) of bearing support (3) to 60 N.m (44 lb-ft).

13. Repeat this procedure with the other final drive.
