A track link includes an elongate link body formed of a link body material that varies in hardness to form a first lower hardness zone, a second lower hardness zone, and a higher hardness zone. The higher hardness zone includes an upper rail surface of the elongate link body and extends substantially throughout the elongate link body outside of the first and second lower hardness zones, which surround the track pin bores. Related methodology for making a track link is also disclosed.

A master link for a track chain is disclosed. The master link may include a first portion that abuts a first face of the link, a second portion that abuts a second face of the link, a first bore located on a first end of the link, a second bore located on a second end of the link, and a material located between the first portion and the second portion and extending between the first bore and the second bore. The material may create a separation between the first portion and the second portion to facilitate placement of the first bore and the second bore around outer diameters of corresponding mating members of a track chain. The material may be removable to remove the separation from between the first portion and the second portion.

A tread link assembly is provided for improving the performance of a wheel on loose surfaces. The tread assembly includes a plurality of linked plates forming a circuit around the outer circumference of the wheel. The linked plates include first and second linking structures and releasable fasteners for linking adjacent plates together. The together the plates create a tread surface that is wider than the axial width of the wheel.

A seal assembly for sealing a lubricant space that is formed between a pin, a track shoe pressed-on onto one end of the pin, and a sleeve of a track. The sleeve is pushed onto the pin and is swivelable on the pin. The track further includes at least one second track shoe pressed onto one end of the sleeve. The seal assembly provides a first seal ring for sealing the lubricant space between the sleeve and the first track shoe, and an elastic ring for applying pressure to the first seal ring. The seal assembly further provides a second seal ring for sealing the lubricant space between the sleeve and the first track shoe and/or the pin.

A track shoe includes a base plate, a grouser extending from the base plate, and at least one white iron member. At least a portion of the grouser includes a substantially martensitic structure. The at least one white iron member is fixed to a portion of the grouser.

A swage tool includes a plurality of swage projections that each defines an angular circumferential extent, and the sum of each of these angular circumferential extents is at least 290 degrees.
