<p>A reconditioned worn chain link (11) with a body and opposed ends has a slightly increased cross-section (24) at its mid portion which has less tensile strength than a new original link as a result of heat treatment but less overall length while maintaining identical pitch. The method for reconditioning includes the steps of applying intense concentrated heat to the mid portion of a worn link (11) to permit reforming and using compression means (15,16) to compress at least one end toward the other to shorten said link (11) slightly a predetermined distance to restore its original pitch.</p> |
