Adjusting Wheels-Cast
1. Clean axle with a steel brush. 2. Raise the tractor on level ground and turn wheel so the rack on the axle faces upward. 3. Loosen the two key-sleeve bolts against the retaining nuts. Loosen the three hub sleeve bolts. 4. Install sleeve bolts as jack screws on the upper and lower hub sleeves to loosen sleeves. Tighten screws up to 500-600 N·m (370-440 lb-ft) if necessary. NOTE: If sleeves are difficult to break loose, strike end of axle with a heavy hammer. Penetrating oil can also help. Retighten jack screws. 5. Remove jack screws from upper hub sleeve and install JDG667A (100 mm axle) or JD668A (110 mm axle) Wheel Adjusting Tool (available from your John Deere Dealer) using sleeve bolts. (Spacer plate of tool goes behind sleeve.) Remove adjusting tool. IMPORTANT: Keep the face of hub sleeves even to prevent hub breakage or bolt loosening. 6. Tighten hub sleeve bolts to 204 N·m (150 lb-ft) beginning with key-sleeve bolt in lower hub sleeve, then criss-crossing other bolts. Retighten bolts to 410 N·m (300 lb-ft). Drive tractor a minimum of 100 m (100 yd) and tighten bolts to 600 N·m (440 lb-ft). IMPORTANT: Under scraper and severe applications tighten wheel bolts every 2 HOURS until all cap screws remain at 600 N·m (440 lb-ft). 7. Recheck all bolts after 3 HOURS and again after 10 HOURS to ensure correct torque specification. |
