Abstract: An onboard track machine wear measurement system has an ultra-sonic probe that is attached to an undercarriage of the machine that is disposed adjacent a track chain assembly, and a controller that is in communication with the ultra-sonic probe. The controller is configured to determine the thickness of a load bearing wall of a track component of the track chain assembly.

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

Abstract: A replacement kit for a rotating member attachment assembly includes a first thrust washer defining a first thrust washer diameter and a first thrust washer axial thickness, and a first end cap defining a first end cap axial thickness and including a first end cap circumferential surface defining a first end cap diameter that is greater than the first thrust washer diameter. The first end cap circumferential surface includes external threads.

Abstract: A track chain member includes a first rib coupling the shoe member to the first lug; and a second rib coupling the shoe member to the second lug, defining a first side recess between the first rib and the second rib. The first side recess also extends from the exterior of the shoe member and underneath the first top surface, the first lateral end defines a first lateral end width along the track chain traveling direction, and the first side recess also spans the majority of the first lateral end width along the track chain traveling direction.
