E. Wheel Installation
Torque lug nuts after first 50 hours and after each wheel installation.
Note: If machine is equipped with directional tire assemblies, the wheel and tire
assemblies must be installed with the directional tread pattern “arrows” facing in the
direction of forward travel.
1. Start all nuts by hand to prevent cross threading. DO NOT use a lubricant on
threads or nuts.
2. Tighten lug nuts in an alternating pattern as indicated in figure. See page 9-5 for
tire torque values.
WARNING
TIP OVER HAZARD. Lug nuts must be installed and maintained at the proper
torque to prevent loose wheels, broken studs and possible separation of wheel
from the axle.
