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.

A slider includes a first segment and a second segment. The first segment includes a first upper surface, a first lower surface, and a first interior surface that connects the first upper surface to the first lower surface. The first upper surface is configured to support a track. The first interior surface includes a first component of an attachment mechanism. The second segment includes a second upper surface, a second lower surface, and a second interior surface that connects the second upper surface to the second lower surface. The second upper surface is configured to support the track. The second interior surface includes a second component of the attachment mechanism that is configured to be removably attached to the first component.

A track slider mounting plate kit includes a first shark fin configured mounting plate including a first bottom mounting surface, a first beveled surface extending from the first bottom mounting surface, and a second beveled surface that extends from the first beveled surface, forming a first oblique angle with the second beveled surface. A track slider is attached to the first shark fin configured mounting plate that has a top surface extending from the rear surface toward the front surface defining a top surface radius of curvature ranging from 2200 mm to 2600 mm.

A transition track slider has a hollow body including a first side surface, a second side surface, a bottom surface at least partially interposed between the first side surface and the second side surface, and that also defines a cavity. A front surface with a bullet nose configuration connects the first side surface to the second side surface, and to the bottom surface, while a rear surface connects the first side surface to the second side surface, and to the bottom surface. A top surface extends from the rear surface toward the front surface.

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.

A track pad includes a shoe member that has two bottom voids extending upwardly from the ground engaging surface of the shoe member, and which form a central support pillar having a serpentine surface laterally on side of the central support pillar, and another serpentine surface laterally on the other side of the central support pillar. The two bottom voids form oval perimeters at the ground engaging surface.

A track chain member includes a shoe member, and a first rail member extending from the shoe member. The first rail member includes a first lug defining a first bore defining a first longitudinal axis and including a first bushing retention shelf disposed in the first bore, as well as a second lug including a second bushing retention shelf disposed in the second bore. A third lug extends in a direction opposite that of the first lug and second lug and is disposed axially between the first lug and the second lug.

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.

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.

A track chain member includes a shoe member, and a first rail member extending from the shoe member. The first rail member includes a first lug defining a first bore defining a first longitudinal axis and including a first bushing retention shelf disposed in the first bore, a second lug including a second bushing retention shelf disposed in the second bore. A third lug extends in a direction opposite that of the first lug and second lug and is disposed axially between the first lug and the second lug.

A slider for a track assembly of a machine is provided. The slider includes an elongated base portion coupled to a frame and a sliding portion extending from the elongated base portion. The sliding portion includes an outer surface configured to slidably engage with a track link of the track assembly. The sliding portion includes a set of wear indicators defined in the outer surface. The set of wear indicators includes a first wear indicator and a second wear indicator. The first and the second wear indicators are located at a first predefined thickness and a second predefined thickness respectively, measured along a central axis of the sliding portion. Further, the first wear indicator indicates partial wear of the sliding portion and the second wear indicator indicates substantial wear of the sliding portion.

A track support rail for slidably supporting a track assembly of a machine includes a body having a first body end, a second body end, a crown portion, and an upper support surface. The body extends along a longitudinal axis between the first and second body ends. The crown portion is disposed between the first and second body ends along the longitudinal axis. The upper support surface extends along the longitudinal axis between the first and second body ends. The upper support surface includes first and second curved segments. The first curved segment has a first curved shape and extends from the first body end toward the crown portion of the body. The second curved segment has a second curved shape and extends from the second body end toward the crown portion of the body. The first curved shape is different from the second curved shape.
