Wheels: Testing and Inspection
Wheel Mounting Surface Check
You must replace any wheels which are bent, dented, or which have excessive lateral or radial runout. Wheels with runout greater than specified may
cause objectionable vibrations.
1. Use a straight edge 203-229 mm (8-9 inch) long. Place the straight edge on the wheel inboard mounting surface. Try to rock the straight edge up
and down within the mounting surface.
2. Repeat this procedure on at least 3 or 4 different positions on the inboard mounting surface.
^
The outer ring of the mounting surface normally is raised above everything inside the mounting surface.
^
The mounting surface will be raised above the outer ring if the wheel mounting surface has been bent on a tire changer.
