Abstract: An idler assembly for a track roller frame includes a housing element having a central cavity, the housing element being connectable to an end of the track roller frame. A yoke element is movably disposed in central cavity and has spaced apart first and second arms, the yoke element is connectable to a longitudinally extending piston in the track roller frame. At least one key element couples the yoke element to the housing element such that the yoke element is movable relative to the housing element. An idler wheel is rotatably supported between the first and second arms.

Abstract: Linkage pins are commonly used to join two members to provide a rigid connection or to function as a pivot point. They are often manufactured from piece parts that ideally are provided with a protective coatings before assembly. The joint needs to be able to withstand the harsh environments linkage pins may be used in and the joining process must cause minimal disturbance to the coating to prevent it from having to be reapplied after manufacturing. The present invention discloses a method and linkage pin including a mechanical deformation to form a joint. The components are arranged in a particular orientation to provide optimum durability by aligning them in a direction dependent on the direction of the flexing caused by the forces acting upon the pin.
