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.
