Abstract
A method of reducing noise on an idler wheel of a track type tractor is provided. The idler wheel includes a tread surface and a retaining surface on an outer periphery. The method includes machining the tread surface to a depth less than a predefined tolerance limit. The method further includes forming a metal mesh on the tread surface wherein the metal mesh is structured to define space between the tread surface and metal mesh to form a three dimensional structure. The method includes filling the space between the three dimensional structure and the tread surface with a noise reducing material to a predefined height.
