nut for each wheel. Either single or dual wheels can be
securely mounted on the same hub with this
arrangement. The outer nut must be loosened first to free
the outer wheel disc from the hub. Loosening the outer
nut, which threads over the inner nut, unfastens the outer
wheel disc. In removing dual-disc wheels, you will find
left-hand threads on both inner and outer nuts on the left
wheels and right-hand threads on those of the right
wheels.
Reverse the procedure to mount and tighten the
wheels. Dual-disc wheel mounting is shown in figure
3-25.
On trucks having spoke wheels, remove the clamps
which secure the rim on the spoke wheel (fig. 3-26), and
lift off the rim with the tire and tube. If the spoke has
two tires, the second rim and tire can be lifted off after
the spacer separating the rims is removed. When
installing the wheels, install the outer dual in a position
that places the valve stem 180 degrees from the stem on
the inner tire (fig. 3-27).
TIRE REPAIR
Facilities for repairing tires vary from one location
to another. Some deployment locations have power-
operated tire repair equipment to support tire repair. This
