Abstract
A self-aligning idler wheel assembly for a belted work vehicle includes a spindle having first and second radially extending flange portions. First and second self-aligning mechanisms are associated with a respective flange portion. The vehicle has an undercarriage assembly including a belt tensioning mechanism and a roller frame assembly. The first self-aligning mechanism connects the idler wheel assembly to the belt tensioning mechanism and the second self-aligning mechanism connects the idler wheel assembly to the roller frame assembly. The first and second self-aligning mechanisms provide self-aligning of the idler wheel assembly to ensure that the track belt runs straight and true.
