Wheel Nuts
Wheel nut torque must be checked before initial operation and every two hours
thereafter until the wheel mounting hardware torque stabilizes at the
recommended setting of 120-130 ft-lbs (161-175 N·m). When tires are removed
and replaced, this procedure must be repeated.
Tires
Rear tires usually wear faster than the front ones. To keep tire wear even, rotate
the tires from front to rear and rear to front.
It is important to keep the same size tire on each side of the loader to prevent
excessive wear on tires or other damage. If different sizes are used, each tire will
be turning at different speeds, causing excessive wear.
The tread bar of all tires must face the same direction.
Mounting Tires
Inflating or servicing tires can be dangerous.
When possible, trained personnel should
service and mount tires. To avoid possible death or serious injury,
follow the safety precautions below.
1. Be sure the rim is clean and free of rust.
2. Lubricate the tire beads and rim flanges with a soap solution. Do not use oil
or grease.
3. Use a clip-on tire chuck with remote hose and gauge, allowing you to stand
clear while inflating the tire. Do not place your fingers on the tire bead or rim
during inflation.
4. Never inflate beyond 35 psi (240 kPa) to seat the beads. If the beads have not
seated by the time the pressure reaches 35 psi (240 kPa), deflate the assembly,
reposition the tire on the rim, lubricate both parts and re-inflate. Inflation
pressure beyond 35 psi (240 kPa) with unseated beads may break the bead or
rim with explosive force sufficient to cause death or serious injury.
5. After seating the beads, adjust the inflation pressure to the recommended
operating pressure.
6. Do not weld, braze or otherwise attempt to repair and use a damaged rim.
