Abstract: A method of remanufacturing a prechamber assembly includes determining a width W of an original circumferential weld bead that extends around and joins a proximal end of an outer peripheral wall of a prechamber housing and a distal end of an outer peripheral wall of a body assembly, cutting through the weld bead in order to separate the prechamber housing from the body assembly, and removing material from an outer peripheral portion of a distal end portion of the body assembly. 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.

Abstract: The present disclosure is related to a method of determining a height of an upper surface of an insert relative to a top deck surface of a cylinder block. The method includes detachably coupling a fixture to the top deck surface of the cylinder block. The method also includes disposing a dial gauge on the top deck surface adjacent to each of a plurality of notches defined in the fixture. The method includes inserting a probe of a dial gauge through each of the plurality of notches to contact each of corresponding portions of the upper surface of the insert. The method also includes determining local heights of the upper surface of the insert relative to the top deck surface at the corresponding portions of the upper surface. The height of upper surface of the insert relative to the top deck surface is determined based on the local heights.
