An idler assembly (20) for a track roller frame (18) is disclosed. The idler assembly comprises a housing element (32) having a central cavity (38), the housing element (32) being connectable to an end of the track roller frame (18). A yoke element (34) is movably disposed in central cavity (38) and has spaced apart first and second arms (60, 62), the yoke element (34) is connectable to a longitudinally extending piston (68) in the track roller frame (18). At least one key element (36) couples the yoke element (34) to the housing element (32) such that the yoke element (34) is movable relative to the housing element (32). An idler wheel (21) is rotatably supported between the first and second arms (60, 62). |
