It is necessary to check play of final drive shaft end 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 shaft end (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: 1. Drain final drive oil through drain screw (2).2. Remove final drive from machine. |
3. Remove bearing housing (3) and shaft seal (5) of drive pinion (4). 4. Install drive pinion bearing housing (3), without shaft seal (5). Take care to assemble the same shims (6). Tighten bearing housing (3) bolts (7) to 60 N.m (44 lb-ft). 5. Remove shaft end nut cap (8) and locking pin (10). 6. Check castle nut (9) torque, it should be 150 N.m (110 lb-ft). 7. Rotate shaft end (1) several times in both directions. Using an aluminum hammer, lightly tap both sides of shaft end to seat bearing cups. |

8.
Check shaft end (1) rolling drag torque through castle 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 an aluminum hammer and lightly tap both sides of shaft end 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 bolt (10). Seal and install nut cap (8).
11. Remove drive pinion bearing housing (3) and install shaft seal (5). 12. Install drive pinion bearing housing (3), taking care to use the same shim (6). Tighten bearing housing (3) bolts (7) to 60 N.m (44 lb-ft). 13. Repeat this procedure with the final drive on the other side. |
