Abstract: A track joint assembly in a track-type machine includes a track link having a pin bore and a bushing bore formed therein. A track pin is attached to the track link within the pin bore, and a track bushing is attached to the track link within the bushing bore. The track pin and the track link are attached by way of a tight interference-fit, and the bushing and track link are attached by way of a light interference-fit. Once placed in service, the bushing can commence rotation during track operation to reduce wear and obviate the need for bushing turns during servicing.

Abstract: A pair of master track links has a first master track link including a first body. The first body defines a first bore and includes a first interface region including a plurality of teeth, and at least one tooth of the plurality of teeth includes a free end and a crown defining a crown width proximate the free end of the at least one tooth. The at least one tooth also includes a root disposed opposite the crown defining a root width, and the crown width is greater than the root width.
