A pair of master track links has a first master track link including a first body. The first body defines a first bore and includes a first interface region including a plurality of teeth, and at least one tooth of the plurality of teeth includes a free end and a crown defining a crown width proximate the free end of the at least one tooth. The at least one tooth also includes a root disposed opposite the crown defining a root width, and the crown width is greater than the root width.

A master link for a track chain is disclosed. The master link may include a link body extending from a first end to a second end and a plurality of apertures extending through the link body. The plurality of apertures may include a first aperture positioned proximate the first end, a second aperture unconnected to the first aperture and positioned proximate the second end, and a third aperture arranged between the first and second apertures. A first gap may extend between and connect the third and second apertures. The master link may also include a threaded first fastener that is configured to extend through the link body across the third aperture.

A method for manufacturing a machine component includes forming a non-linear break notch in a workpiece, freezing the workpiece, and snapping the frozen workpiece apart along the non-linear break notch.

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.

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 first and second threaded pin bores and first and second threaded passages, a master link pin with threads on the outer circumferential surface along a distal portion, and first and second fasteners. The master link pin may be inserted into the master link box through one of the first or second pin bores. The fasteners may be secured in the threaded passages such that the first fastener abuts a proximal portion of the master link pin and the second fastener abuts a distal portion of the master link pin.

A master link for a track chain is disclosed. The master link may include a link body extending from a first end to a second end and a plurality of apertures extending through the link body. The plurality of apertures may include a first aperture positioned proximate the first end, a second aperture unconnected to the first aperture and positioned proximate the second end, and a third aperture arranged between the first and second apertures. A first gap may extend between and connect the third and second apertures. The master link may also include a threaded first fastener that is configured to extend through the link body across the third aperture.

An offset link track chain may include a plurality of link subassemblies including a first link subassembly and a second link subassembly and a master link assembly removably coupled between the first link subassembly and the second link subassembly. Each link subassembly of the plurality of link subassemblies may include a pair of offset links coupled together. The master link assembly may include a pair of straight links. Each straight link may include a link body having (a) a first aperture positioned proximate a first end, (b) a second aperture positioned proximate a second end, and (c) a threaded fastener. Changing a relative position of the fastener with respect to the link body may change a diameter of the first and second apertures.

A clamping master track link includes a body that defines a first bore and a second bore, a first aperture disposed between the first bore and the second bore, a second aperture disposed between the first aperture and the second bore, a first strut with a first gap disposed between the first aperture and the second aperture, a second strut with a second gap disposed between the first aperture and the first bore, and a bridge disposed between the second aperture and the second bore. The first bore defines a cylindrical bore surface that is at least partially textured.

A track chain assembly includes a track pin, a first link, and a second link. The first link defines a first pair of pin passages in spaced relationship to each other by a first link pitch. The first link is mounted to the track pin such that the track pin extends through one of the first pair of pin passages. The second link defines a second pair of pin passages in spaced relationship to each other by a second link pitch. The second link is mounted to the track pin such that the track pin extends through one of the second pair of pin passages and such that the first link and the second link are rotatable with respect to each other about a longitudinal axis defined by the track pin. The second link pitch is greater than the first link pitch in a range up to twice the first link pitch.

A track chain assembly comprises a plurality of track links connected to each other by either a track pin or a track bushing, a first master track link including a first interface region including a plurality of teeth, a second master track link including a second interface region including a plurality of teeth, and the first interface region and the second interface region are configured such that the plurality of teeth of both the first master track link and second master track link are configured to share substantially the same load when the track chain assembly is in use.
