NOTE: The valve stem on the inner and outer assemblies will most likely not align through the same window. Although the valve stem of the inner assembly may not be as easy to locate, it is still possible to put air in the inner assembly without removing the outer assembly. The customer should be informed of the valve stem position and the reason for the alignment.
NOTE: Road Force® values in illustrations are shown in pounds.
