    Abstract: An articulated chain assembly includes standard links, a master link, and pins pivotably coupling together the standard links and master link. The master link includes a first half link and a second half link, and bolt holes extending through the first half link and the second half link. A first bolt is within a first one of the bolt holes and has a necked-down bolt shank defining a lesser necked-down axial length. A second bolt is within a second one of the bolt holes and includes a necked-down bolt shank defining a greater necked-down axial length. The first bolt and second bolt may have unequal full axial lengths.

    Abstract: Disclosed are various exemplary embodiments of a track joint assembly. In one exemplary embodiment, the track joint assembly may include a first link having a first bore. The track joint assembly may also include a second link having a second bore including first and second portions. The first and second portions may have different diameters. In addition, the track joint assembly may include a solid pin positioned at least partially within the first bore. The track joint may also include a bushing positioned coaxially around the pin. The bushing may include an axial end portion disposed in and contacting the first portion of the second bore. The bushing may also include an axial end-adjacent portion disposed in and contacting the second portion of the second bore. An outer diameter of the end-adjacent portion may be larger than an outer diameter of the end portion.

    Abstract: A track link for a ground-engaging track includes an elongate link body having a lower hardness material forming a lower mounting surface for mounting a track shoe, and a sacrificial higher hardness material forming an upper rail surface for contacting rotatable track engaging elements. The lower hardness and higher hardness materials transition at a material interface within the elongate link body, and the material interface is longitudinally non-uniform, such that the sacrificial higher hardness material has a varying depth from the upper rail surface to retard scalloping.
