Columbia Machine Works technicians discovered a crack in the bore for the rod’s wrist pin. We machined the old ‘knuckle end’ off, and machined dowel pin holes into the rod. We then fabricated a new ‘knuckle end,’ fitted the new part into the rod using dowels, and welded the assembly together. We then machined the newly-formed part back into spec. This repair method is a significant cost savings to the customer versus replacing the old rod with a new one.
