ROAD WHEEL REPLACEMENT CONTINUED
Replacing a Road Wheel
00047
WARNING
If, for whatever reason, a wheel stud is replaced, all the studs for that wheel must be replaced as a
set, since the remaining studs may have been damaged. Failure to follow this warning may result in
the road wheel coming loose at convoy speeds, resulting in loss of machine control. This may result
in injury or death to personnel.
Do not use a machine with visible signs of damage to the road wheels or wheel nuts. Failure to
follow this warning may result in injury or death to personnel.
Once in position and the engine is shut down, do not turn on the ignition again until either the road
wheel has been fitted or the axle suitably chocked. The active suspension will cause the axle to
drop if either of these conditions is not met and the ignition is turned on. Failure to follow this
warning may result in injury or death to personnel.
1.
Ensure that the mating faces of the road wheel and axle hub are clean and free of debris. With assistance, position the road
wheel on the wheel studs. Install the wheel nuts and tighten sufficiently to hold the road wheel in place.
2.
Remove the jack stand from under the axle and lower the machine to the ground.
WARNING
The wheel nuts must be torque tightened. Over- or under- torquing may result in wheel nut failure.
Failure to follow this warning may result in injury or death to personnel.
3.
Torque the wheel nuts to 370 lb-ft (500 Nm) in the order shown in Figure 2.
