Abstract
A noise attenuating assembly for reducing noise levels caused by an endless track assembly during operation of an off-highway implement such as a crawler tractor. The noise attenuating assembly comprises an annular elastomeric ring affixed about an idler wheel on the track assembly. The elastomeric ring is positioned such that pin and bushing assemblies of the track assembly directly and resiliently engage with the periphery of the ring thereby reducing noise as the track assembly rotates about the wheel. A ring retaining assembly which circumferentially extends in recessed relation about the outer periphery of the ring facilitates assemblage of the ring to the idler wheel.
