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 cartridge pin assembly in a track chain assembly includes a sleeve bearing having a flared end.

A track pin assembly includes a pin having a first axial end and a second axial end configured to engage a respective outer link of a joint, a first cavity which defines a tank for containing lubricating oil or grease, and a second cavity arranged at the second axial end of the pin and open at the second axial end of the pin. A sensor, arranged in the second cavity, includes a sensor element configured to measure a temperature and to generate a signal indicative of the measured temperature, and a transmitter configured to irradiate a measuring signal that is representative of the signal generated by the sensor element. A power source, arranged in the second cavity, is configured to constantly supply the sensor.

A bushing for a track assembly, according to one or more embodiments, includes: a tubular bushing substrate having a longitudinal length and an outer surface; and at least one white iron member fixed to the outer surface of the tubular bushing substrate.
