Abstract: The present disclosure provides a dump body for a machine. The dump body comprises a floor, a front wall, a pair of side walls being structured and arranged to form a material collection structure. A contoured surface being formed between at least one combination of the floor, front wall, and the pair of side walls. Further, an exhaust passage having at least a portion of wall being defined by the contoured surface is provided in the dump body, wherein the contoured surface is configured to be in fluid communication with exhaust through the exhaust passage.

Abstract: A method for rebuilding a truck body is provided. The method places a plurality of supports on a segment of a truck body. The plurality of supports defines at least a portion of the segment requiring rebuild. The method then places a rebuilding surface atop the plurality of supports. The rebuilding surface defines a void created between the rebuilding surface and the segment. The method also affixes the rebuilding surface atop the plurality of supports. The method further injects a layer of filler material into the void.
