ABSTRACT:
A support is provided for rotatable mounting on a circular brake backing plate mounting flange of an axle end spaced inward of the terminal end thereof to be cut from the axle end and replaced by an axle stub end. The support includes structure for mounting a cutting torch tip therefrom in position to cut the terminal end of the axle end therefrom along a circumferential zone spaced slightly outward of the backing plate. A cylindrical jig is also provided including structure on one end for mounting to the backing plate in concentric relation therewith and the jig includes internal structure supporting and journaling an axle stub therefrom in axial alignment with the jig and with the axle stub being adjustably positionable along its longitudinal center axis to a position with its inner end abutted against the cut end of the axle end. The jig includes circumferentially spaced windows therein through which tack welding of the axle stub end to the cut axle end may be accomplished and after the tack welding operation has been completed the jig may be removed to expose the tack welded joint between the axle end and the axle stub end for access thereto in forming a continuous weld bead thereabout.
