Title: A METHOD OF REMANUFACTURING A PRECHAMBER ASSEMBLY
Abstract:
A method of remanufacturing a prechamber assembly includes determining a width W of an original circumferential weld bead (50) that extends around and joins a proximal end of an outer peripheral wall of a prechamber housing (30) and a distal end of an outer peripheral wall of a body assembly (20), cutting through the weld bead (50) in order to separate the prechamber housing (30) from the body assembly (20), and removing material from an outer peripheral portion of a distal end portion of the body assembly (20). The method includes removing the material in an axial direction parallel to the central axis of the prechamber assembly for a distance that is from 2.5 - 3 times the width W.
