Machine Specifications and Operator Maintenance
• If any uneven wear is discovered.
A tire with significant damage in the tread area or sidewall requires immediate
evaluation before placing the machine into service. If a cut, tear, chunk, or other
discrepancy exceeds any one or more of the following dimensions, the tire must be
replaced:
3.0 in. (76 mm) long
0.75 in. (19 mm) wide
0.75 in. (19 mm) deep
• If the metal wheel is visible at any point through the tread area of the tire.
• If more than one discrepancy exists in any quadrant of the wheel (within 90 degrees
of one another).
6.8.3 Wheel Installation
It is extremely important to apply and maintain proper wheel mounting torque.
Wheel bolts must be installed and maintained at the proper torque to prevent
loose wheels, a broken bolt, and possible separation of wheel from the axle.
Tighten the wheel mounting bolts to the proper torque to prevent wheels from coming
loose. Use a torque wrench to tighten.
1. Install wheel (1) onto hub (2).
2. Start mounting bolts (3) by hand to prevent cross threading. DO NOT use a
lubricant on threads.
3. Tighten bolts in the following sequence:
4. Tighten bolts in stages. Following the recommended sequence, tighten each bolt
per wheel torque of 58 Nm (43 ft.lb.).
5. Wheel mounting bolts should be torqued after the first 50 hours of operation and
after each wheel removal. Check torque every 3 months or 150 hours of operation.
