CAUTION: Avoid the possibility of personal injury. Never operate tractor with loose wheel bolts. Wheel bolts are critical and require retightening.

IMPORTANT: Do not use clamp-on dual wheels with steel wheels, on flanged axle.

Tightening Sleeve Retaining Bolts

1. Install sleeve retaining bolts (C) and tighten to 204 Nm (150 lb-ft).
2. Retighten to 410 Nm (300 lb-ft).
3. Drive tractor 100 meters (110 yd), then tighten bolts (C) to 600 Nm (445 lb-ft).
4. Retighten bolts after operating 3 HOURS and 10 HOURS.

IMPORTANT: When sleeve retaining bolts (C) have been loosened, both sleeve halves must be tightened evenly to prevent hub cracking or bolt loosening.
