Abstract: 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.

Abstract: A track roller assembly may have a track roller, a roller shaft and collars 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 of the track roller. A compressive axial load 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 track roller frame is provided for an endless track. The track roller frame includes a shaft including a body portion and a flange. A first bearing assembly rotatably supports a first rim portion on the shaft and a second bearing assembly rotatably supports a second rim portion on the shaft. Each of the first bearing assembly and the second bearing assembly includes a first leg that extends in the axial direction and is disposed along the body portion of the shaft and a second leg that extends in the radial direction and is disposed along the flange. A respective inner surface of each of the first rim portion and the second rim portion that faces the bearing assembly includes a plurality of lubricant pockets for receiving lubricant. Each of the lubricant pockets is configured and arranged such that lubricant contained therein is in fluid communication with the bearing assembly.

Abstract: An ID tag is disposed on a plurality of components of a machine. A controller stores a usage threshold for each component, receives signals from an ID tag reader, and associates an identification number from each ID tag with a component of the machine. The controller determines previous usage data for each component, determines an extent of usage of the machine since generation of the previous usage data, determines current usage data for each component based upon the extent of usage of the machine and the previous usage data, and compares the current usage data for each component to the usage threshold for each component. The controller generates an alert for each component in which the current usage data for that component exceeds its usage threshold and transmits the alert to a system remote from the machine.
