Abstract
The following specification describes a replacement method and part for a coupler butt end in which the coupler is severed at the narrow hollow perimeter wall of the coupler shank close to the solid worn butt end portion. A cast replacement butt end part having a chamfer at the front end and a ring lip spaced inwardly of the front end is fitted to the coupler shank and welded thereto. The lip serves as a back up for the weld between the end surfaces of the coupler shank and the front end of the replacement part.
