In some implementations, a bushing may include a cylindrical body having an at least partially annular configuration. The cylindrical body may define a radial axis and may include an inner circumferential surface, an outer circumferential surface, a first end, and a second end. The inner circumferential surface may be configured to rotatably receive an outer surface of a pin of a track link joint. The outer circumferential surface may be configured to be rotatably received within a first counterbore of a first track link of the track link joint. The bushing may include at least one groove extending radially into the outer circumferential surface around the radial axis. The at least one groove may be configured to receive a first seal of the track link joint. The first seal may form a first radial seal between the outer circumferential surface and a first inner surface of the first counterbore.

Radial seal for a track link joint

A track roller rim is disclosed. The track roller rim may include an outer member including an annular configuration defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation, where the outer member has an inner circumference, an outer circumference, a first axial end disposed along the axis of rotation, and a second axial end disposed along the axis of rotation. The track roller rim may include a first annular inner member, where the first annular inner member is interference fit within the inner circumference of the outer member at the first axial end. The track roller rim may include a second annular inner member, where the second annular inner member is interference fit within the inner circumference of the outer member at the second axial end.

Fabricated track roller rim assembly

A seal includes an annular body defining a radial direction, an axial direction, and a circumferential direction; and further defines a cross-sectional area including a perimeter. The perimeter may comprise a first axial extremity, a second axial extremity, an outer radial extremity, and an inner radial extremity. The perimeter may include a first axial extremity defining surface and a second axial extremity defining surface, a first concave arcuate surface interposed between the inner radial extremity and the second axial extremity, and a second concave arcuate surface interposed between the outer radial extremity and the second axial extremity.

Lip seal

A master link box for use with a link assembly of a work machine is disclosed. The master link box may include first and second master links with pin bores and lateral annular recesses disposed around the pin bores, a master link pin with a radial projection at a proximal end and a distal annular groove in the outer circumferential surface near the distal end, and a master retaining ring. The master link pin may be inserted through either master link until the radial projection of the master link pin abuts the lateral recess of one of the master links. The master retaining ring may be secured in the distal annular groove to prevent the master link pin from retracting through the master link box. The master retaining ring may be secured in the distal annular groove without press-fitting the master retaining ring.
