An endless track chain assembly for an endless track vehicle having drive teeth received in tapered slots in a drive wheel. The drive teeth are replaceable in situ by a movement in a direction parallel to the rotational axis of the drive wheel. The drive teeth inter-fit with tapered inserts on the endless chain assembly so that all the driving forces are transmitted between the two replaceable wear elements. The inserts are inter-connected with pairs of links in a three point mounting as a structural unit to increase torsional rigidity and enable bushings that inter-connect adjacent links to be smaller that conventional bushings. The inserts on the endless chain assembly are readily replaceable by fasteners accessed from the exterior of the endless chain assembly.
