    Abstract: The present disclosure is directed to a pin joint component for a pin joint assembly that has improved wear surfaces, especially for those portions of the pin joint component surface that interface thrust rings, lips, and other adjacent wear components. The pin joint component comprises a first treated region that is formed by removing material from the wear surface of the pin joint component and replaced with clad material. Prior to this operation, a second treated region is formed by removing material from a section of the pin joint component distinct from the first treated region and performing a nitriding process thereon.

    Abstract: A track roller assembly may have a track roller (32), a roller shaft (40) and collars (42) press fit onto either end of the roller shaft to retain the track roller on the roller shaft with an axial clearance between the collars and the track roller. During assembly, the collars may be press fit onto the shaft ends and forced axially inwardly until further axial movement of the collars is prevented by engagement shoulders (56) of the track roller. A compressive axial load (120) may be applied to the roller shaft to reduce a shaft length of the roller shaft and to cause the roller shaft to slide inwardly relative to the collars. The compressive axial load is removed from the roller shaft so that the roller shaft extends back to the normal shaft length and the collars move axially farther apart as the roller shaft extends back to the normal shaft length.

    Abstract: A seal assembly can be incorporated into a track pin joint assembly including a pin defining a longitudinal axis, a first member and a second member both coaxial with the pin about the longitudinal axis. The first member is pivotable about the longitudinal axis with respect to the second member and includes a load ring engagement surface defining, at least in part, an axially- extending seal cavity disposed in proximal relationship to the second member. A seal assembly including a seal ring and a load ring is disposed in the seal cavity and sealingly engages the first member and the second member. At least one of a load ring engagement surface of the first member and an axial segment of a first member engagement surface of the load ring includes a convex rounded portion extending over at least half the axial length thereof.

    Abstract: A roller assembly (32) for a ground-engaging track system (24) includes a roller (34) forming a shaft bore (42), and a roller shaft (52) within the shaft bore (42) and having a circumferential ramp surface (60). A roller retention system (83) for the roller assembly (32) includes a roller retention collar (84) with an outer peripheral surface (96), and an inner peripheral surface (98) that may include a wedge surface (98) structured to friction fit the retention collar (84), within a collar bore (44) in the roller (34), upon the circumferential ramp surface (60) to limit axial displacement of the roller (34) upon the roller shaft (52). The roller assembly (32) may include two roller retention collars (84,86) supporting the roller (34) against axial displacement without use of thrust washers or the like, and fixing the roller (34) and roller shaft (52) to rotate together relative to a track roller frame (26).
