CHAPTER 2 MAINTENANCE
4 REPAIRS
AUGUST 31, 2008
• Do not lean or rest your body or repair equipment against the restraining device
while the wheel/tire is in the device.
•
• Make sure no one is in the blow-out trajectory area. Always stand to one side
To minimize the risk of tire/wheel failure and loss of vehicle control,
when servicing tire/wheels:
• Do not use cleaning solvent on tires. Solvents cause deterioration of the rubber.
•
•
• Do not use damaged parts.
After initially mounting wheel and tire assembly, recheck lug nut
studs as it will result in inaccurate tightening torque. Failure to follow these
procedures could result in wheel mounting failure and loss of vehicle control.
The front and rear wheels are similar in maintenance, cleaning, and inspection.
4.2.1 Removal
2. Using a jack, overhead crane, or some other suitable lifting device
(minimum 5 ton), raise end of tractor. Before tires leave the ground, loosen
ground. See Chapter 1 for jack stand locations.

assembly.
4.2.2 Disassembly
(See Chapter 3 for Special Tire Changing Tools.)
1. Let air out of tire and remove valve core.

equipment, and safety practices.
