The sprocket member keeps the sprocket centered within the link box while the notches or cut-outs allow mud, dirt, or other material to move out of the link box formed of the track chain assembly by two track bushings and two track links that form a rectangular shaped perimeter. The spacing provided by the wings of the sprocket member reduce wear on the track links near a track bushing and track link interface such as a press-fit connection by spacing the lugs of the sprocket member away from the interface.

A bushing assembly for a track assembly includes a first end element, a second end element, and a central element positioned between the first end element and the second end element. The central element may be interference fit or positioned between the first end element and the second end element, and the central element may include a greater hardness than the first and second end elements. The first end element, the second end element, and the central element form a bushing with a longitudinal opening extending longitudinally through the bushing.

Bushing for a track assembly

A pair of master track links includes one master track link that has a rail portion that defines a length that is greater than 80% of the length of the body of the master track link.

Master track link with unitary rail

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.
