Tires and Wheels - Installation

STANDARD PROCEDURE - DUAL REAR WHEEL INSTALLATION
The tires on both wheels must be completely raised off the ground when tightening the lug nuts. This will ensure correct wheel centering and maximum wheel clamping.





Before installing the wheel to the wheel ring flange make sure that all the cone washers are installed on the wheel flange ring (Fig. 20).
The dual rear wheel lug nuts should be tightened according to the following procedure:
- Install the inner wheel to the hub assembly.





- Install the outer wheel Make sure the valve stems line up with each when aligning the wheels (Fig. 21).





- Install the cone washers for the outer wheel before installing the lug nuts (Fig. 22).
- Tighten the wheel lug nuts in the numbered sequential pattern until they are snug tight. Then tighten lug nuts to specified torque following same number sequence.
- Tighten lug nuts in same numbered sequence a second time to the specified torque. This will ensure that the wheels are thoroughly mated.
- Check lug nut specified torque after 100 miles (160 kilometers). Also after 500 miles (800 kilometers) of vehicle operation.

NOTE: Wheel lug nuts should be tightened to specified torque at every maintenance interval thereafter.
