Abstract: A face seal assembly and rotating assembly for a track machine are disclosed. The face seal assembly includes a first seal ring, an annular housing, a second seal ring, and a bias member. The first seal ring is fixed to a rotating part for rotation about an axis. The first seal ring includes a seal face and a radially outer surface press-fittingly confronting an annular bore in the rotating part. The annular housing is spaced axially inward from the first seal ring and rotationally fixed. The annular housing includes an axially inner surface and a radially inner surface. The second seal ring is disposed axially between the first seal ring and the annular housing. The second seal ring includes a seal face confronting the seal face of the first seal ring. The bias member is compressed between the annular housing and the second seal ring.

Abstract: A ground-engaging track shoe in a track joint assembly includes a shoe plate having bolt holes extending through a middle plate section between a planar link-bolting surface and a ground-contact surface. A weight relief channel is formed in the middle plate section upon a link-bolting side of the track shoe, and extends inwardly from the planar link-bolting surface. The weight relief channel is arranged between a forward bolt hole set of the bolt holes and a back bolt hole set of the bolt holes in a fore-aft direction.

Abstract: A wear monitoring system includes a pair of track links for a track assembly of a machine, with a sensing device disposed within a cavity formed in a link body of each of the pair of track links. One or more communication devices are associated with the sensing devices, and a computing device is wirelessly connected over a communication network with each of the communication devices. One or more of the sensing devices and the computing device are configured to detect one or more of a distance between the sensing device disposed in one of the pair of track links and the sensing device disposed in another of the pair of track links, and a distance between the sensing device disposed in one of the pair of track links and a remote device. The computing device is configured to determine internal wear between components of at least one of the pair of track links based on changes in the detected distance.
