Abstract: A track link assembly includes a first track link having a passageway defined therethrough. The track link assembly also includes a bushing having an end face, wherein the bushing is positioned within the passageway. The track link assembly further includes a first seal member having an exterior surface, the first seal member being secured to the bushing end face with a resilient bond formed by an adhesive such as Loctite adhesive part number 17430. In addition, the track link assembly includes a protective coating secured to the exterior surface of the first seal member, wherein the protective coating and the first seal member are made of different materials relative to each other. An associated method for maintaining a track link assembly is also disclosed.

Abstract: A tool for cleaning slivers and the like from a surface of a workpiece, such as the bushing of a chain drive track. In one form, the tool includes structure defining a manifold having an opening and arranged to be abutted to the workpiece with the opening juxtaposed to the workpiece surface on which slivers and the like may be deposited. Fluid, such as air, under pessure is delivered into the manifold and directed substantially directly against the juxtaposed workpiece surface to entrain the slivers and other foreign matter on the prelubricated surfaces. A suction is applied to the manifold for sucking the excess fluid and the entrained slivers and other material outwardly from the manifold. In another form, the manifold is movable against complementary wall surfaces to define a chamber in which the workpiece is disposed. Movement of the manifold to and from the wall surface may be effected by suitable powered mechanism.

Abstract: A positioning apparatus initially positions a track chain link and automatically repositions the link in response to forces subjected upon the link by a track assembly machine when forcibly connecting the pin and links to form a track chain.
