Abstract:
A track joint assembly (34) in a track-type machine (10) includes a track link (28) having a pin bore (48) and a bushing bore (50) formed therein. A track pin (30) is attached to the track link (28) within the pin bore (48), and a track bushing (52) is attached to the track link (28) within the bushing bore (50). The track pin (30) and the track link (28) are attached by way of a tight interference-fit, and the bushing (52) and track link (28) are attached by way of a light interference-fit. Once placed in service, the bushing (52) can commence rotation during track operation to reduce wear and obviate the need for bushing turns during servicing.
