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 vehicle track system and assembly for outfitting vehicles for mobility in off-road conditions. Snow, mud, muck, soil, sand, ice, and other fickle conditions are more readily traversed. In an implementation, a spindle, a first driver, a drive sleeve, a second driver, and a single track are all part of the vehicle track assembly. Multiple of these components of the vehicle track assembly are furnished with one or more clocking indicia. The clocking indicia serves to provide rotational alignment indications amid assemblage procedures of the components of the vehicle track assembly. Proper timing of the drivers with respect to each other and attendant engagement with the single track is hence facilitated. Binding or other shortcomings observed with improperly-timed drivers is more readily resolved.

A greasable axle and hub kit assembly and method of installing the greasable axle and hub kit assembly in the frame of a continuous tread machine is provided. The greasable axle and hub kit assembly utilizes at least an inner seal, greased bearing, an anti-spin washer, a fastener, an outer dust cap, an inner seal protector, and an outer seal protection cap to provide for an axle and hub kit assembly with an improved lifetime and a reduced chance of blowouts. The greasable axle and hub kit may further comprise a coupled grease zerk for applying grease to the interior of the hub portion, providing lubrication to the interior components. The greasable axle and hub kit may even further comprise a pilot flange for attaching wheels of varying sizes and materials to the greasable axle and hub kit.
