Wheel Nuts
Wheel nut torque must be checked before initial operation and every two hours until the
wheel mounting hardware torque stabilizes at the following recommended settings:
• Model R135: 161-175 Nm (120-130 lb.-ft)
• Models R150/165: 244 Nm (180 lb.-ft)
Check wheel nut torque every 250 hours thereafter.
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
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.
Important: The tread bars of all tires should point the same direction.
• Be sure the rim is clean and free of rust.
• Lubricate the tire beads and rim flanges with a soap solution. Do not use oil or grease.
• 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.
• Never inflate beyond 240 kPa (35 psi) to seat the beads. If the beads have not seated by
the time the pressure reaches 240 kPa (35 psi), deflate the assembly, reposition the tire
on the rim, lubricate both parts and re-inflate. Inflation pressure beyond 240 kPa (35
psi) with unseated beads may break the bead or rim with explosive force sufficient to
cause death or serious injury.
• After seating the beads, adjust the inflation pressure to the recommended operating
pressure.
• Do not weld, braze or otherwise attempt to repair and use a damaged rim.
