ABSTRACT:
A crawler shoe for a mining shovel or the like includes a portion in which a cylindrical hole is provided for receiving a steel pin which pivotally connects the crawler shoe to an adjacent shoe. The portion in which the hole is provided is fabricated of a work-hardenable steel alloy, such as Hadfield-Manganese Alloy, and the wall of the hole is work-hardened by a tool which expands the diameter of the hole slightly and at the same time compresses and hardens the steel defining and adjacent the hole to a predetermined depth and to a predetermined degree of hardness. The tool comprises a plurality of radially arranged, slightly skewed, rotatable rollers which are mounted on a rotatable body insertable into the hole and which are movable radially outwardly to roll and exert pressure on the wall surface defining the hole.
