ABSTRACT:
Provided are three joint assembly embodiments which each employ one or more threaded pivot pins for joining the leading ends of a first pair of track links with the trailing ends of a second pair of track links and for supporting a bushing adapted for engagement by a drive sprocket. In a first embodiment, the interior of the bushing and the leading ends of the second pair of links are threaded and receive a pair of threaded fasteners and the trailing ends of the first pair of links are pressed on the opposite ends of the bushing. A second embodiment differs from the first embodiment in that only one threaded fastener is used, the opposite ends of the exterior of the bushing are threaded and the trailing ends of the first pair of links are respectively threadedly received thereon. Also, a split wear bushing is removably received on the first-mentioned bushing. A third embodiment is similar to the second in that only one fastener is used however one end of the fastener is not threaded and has the trailing end of one of the second links received thereon.
