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: A core of a non-pneumatic tire is configured to have a tread formed thereon. The core may include an inner circumferential portion associated with a hub, and an outer circumferential portion radially spaced from the inner circumferential portion. The core may further include a support structure extending between the inner circumferential portion and the outer circumferential portion. The support structure may include a plurality of first ribs, and at least some of the first ribs at least partially form cavities in the support structure. The core may also be substantially absent of tread, such that an outer circumferential portion has a radially outward facing surface having a substantially constant diameter spanning between side edges of the outer circumferential portion.
