Adjusting Wheels-Steel1. Raise the tractor on level ground and turn wheel so rack on the axle is upward. 2. Loosen the hub center bolts against the retaining nuts. 3. Remove the outer hub sleeve bolts. Use hub sleeve bolts in the jack screws to loosen sleeves. Tighten jack screws up to 500-600 N·m (370-440 lb-ft) if necessary. NOTE: Strike end of axle with a heavy hammer and use penetrating oil if sleeves are difficult to break loose. 4. Remove jack screws from upper hub sleeve and install JDG667A Wheel Adjusting Tool (available from your John Deere Dealer) using sleeve bolts. Move wheel to desire position. Observe tread width limitations. 5. Remove adjusting tool and jack screws.
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 the center bolts, then criss-crossing the other bolts. Retighten bolts to 410 N·m (300 lb-ft) using the same sequence. Drive tractor a minimum of 100 m (100 yd) and tighten bolts to 600 N·m (445 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). Recheck all bolts after 3 HOURS and again after 10 HOURS to ensure correct torque specification. |
