Abstract
A cartridge assembly for a track chain assembly includes a bushing having a passageway defined therethrough. The cartridge assembly also includes track pin having a longitudinal axis. The track pin is located within the passageway so that a first end portion and a second end portion of the track pin extends outwardly from the passageway of the bushing. The cartridge assembly further includes a first insert having a first bore defined therethrough. The first insert is positioned relative to the track pin such that the first end portion of the track pin is disposed within the first bore. The cartridge assembly also includes a first collar having a first hole defined therein. The first collar is positioned relative to the track pin that (i) the first end portion of the track pin is disposed within the first hole and (ii) the first insert is interposed between the first collar and the bushing, wherein (i) the first collar is fixed in relation to the track pin such that first collar is unable to rotate relative to the track pin and (ii) the first insert is able to rotate relative to the first collar and the track pin around the longitudinal axis.
