A ground-engaging track shoe includes a shoe plate having link-side fixturing surfaces and ground-side fixturing surfaces. The link-side fixturing surfaces and the ground-side fixturing surfaces are raised in profile relative to a link-facing surface and a ground-facing surface, respectively. The fixturing surfaces enable a fixture to clamp the track shoe for support during processing, enabling improvements in maintaining portions of the track shoe flat and reducing part to part variation.

A track pin for a track chain assembly includes a body made from a steel alloy. The steel alloy has a composition comprising iron, a nitride-forming element, a carbide-forming element, and silicon. The composition of the steel alloy comprises at least 0.5 percent by weight of silicon. The body includes a compound layer on an exterior surface thereof. The compound layer includes at least one of Fe.sub.2-3(C,N) microstructures and Fe.sub.4N microstructures formed therein by ferritic nitro-carburizing.

In accordance with the present disclosure, a track chain assembly for a work vehicle may comprise of a link set, a unitary link, and a bushing assembly. The link set may include a first link and a second link. The unitary link may include a single link. The bushing assembly may couple the link set and the unitary link for relative rotation between the link set and the unitary link.

A composite track shoe and an endless track suitable for a tracked vehicle is described herein. The composite track shoes has a shoe body with a first bearing block extending from a first lateral edge and a second bearing block extending from a second lateral edge. The shoe body also has a center guide extending from a first face thereof the shoe body. A track pad is detachably secured to the track shoe and extends from a second face of the shoe body opposite the first face. An endless track is formed by interlinking the first bearing block on a first track shoe with the second bearing block a second track shoe positioned adjacent to the first track shoe. A pin extends through the first bearing block of the first track shoe and the second bearing block of the second track shoe for pivotally coupling them together.

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.
