ABSTRACT:
Apparatus for use in balancing a truck or bus wheel includes an assembly for axially securing such a wheel on a shaft and a stand to rotatably support the wheel-holding assembly while the wheel is being balanced. The stand has spaced shaft supporting members rearwardly and downwardly inclined and provided with stops spaced rearwardly of the front of the stand and hooks that protrude therefrom. The stand has a chamber open at the front and between the members which is of a depth and length greater than the radius of the wheel. With the stand tipped forwardly to position the hooks to receive the shaft of the assembly and then returned to its stable position, the assembly is lifted and held against the stops.
