An articulated chain assembly includes standard links, a master link, and pins pivotably coupling together the standard links and master link. The master link includes a first half link and a second half link, and bolt holes extending through the first half link and the second half link. A first bolt is within a first one of the bolt holes and has a necked-down bolt shank defining a lesser necked-down axial length. A second bolt is within a second one of the bolt holes and includes a necked-down bolt shank defining a greater necked-down axial length. The first bolt and second bolt may have unequal full axial lengths.

Master link and articulated chain assembly for machine

A track roller includes a body having a revolved configuration defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation. A first axial extremity and a second axial extremity are disposed along the axis of rotation. The body of revolution further includes a first rim portion disposed proximate to the first axial extremity, and a second rim portion disposed proximate to the second axial extremity. An outboard track contact surface is disposed axially proximate to the first rim portion, and an inboard slot is disposed axially proximate to the second rim portion.

Flip-flop track rollers

A ground-engaging track includes a track chain formed of standard links and at least one master link. The master link include a first half link and a second half link, clamped together by way of a forward bolt and a rearward bolt. Clamping surfaces of the first half link and the second half link form a first tooth set and a second tooth set, respectively, which may include a total of 2 or 3 full teeth and tooth roots, confined in distribution between a forward bolt hole and a rearward bolt hole.

Ground-engaging track for machine having multi-tooth master link

A track idler includes a body of revolution defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation. A first axial extremity and a second axial extremity are disposed along the axis of rotation. The body of revolution further includes an outboard track contact surface that is disposed axially proximate to the first axial extremity, and an inboard slot is disposed axially proximate to the second axial extremity.

Flip-flop track idlers

A track hinge joint includes a first track link, a second track link, a track pin disposed in a bore of the first track link, an inner bushing that is disposed in a bore of the second track link and that is rotatable relative to the track pin, an outer bushing that is disposed about the inner bushing that is rotatable relative to the inner bushing and that includes an outer bushing end face, and a first fluid seal assembly contacting the outer bushing end face and the second track link.
