-21- Abstract of the Disclosure Apparatus and Method For Turning a Track Bushing Apparatus and method of turning a bushing of a track chain link assembly is disclosed which enables the bushing to be turned in place in the link assembly, thereby eliminating the need to disassemble the link assembly in order to effect the bushing turn. The apparatus includes clamping means having three jaws for clamping the bushing, each of which has a deformable insert of an aluminum alloy so that, upon application of the clamping force, the shape of insert can change to accommodate one-sided sprocket wear on the bushing and insure intimate clamping contact therewith. Each of the deformable inserts is supported on an arcuate surface of a support block which has apertures and grooves for providing space into which material of the insert can extrude to facilitate the ability of insert to conform to the bushing. The grooves are oriented longitudinally so as to provide a mechanical interlock between the insert and the support blocks, thus eliminating any slippage between the block and insert as the links are being rotated.
