Abstract: A tool for the installation, removal and tightening of endless tracks of a tracked vehicle includes a first tubular member that telescopically receives a second tubular member with a rotatable handle mounted to the first tubular member opposite the second tubular member and a threaded rod interconnected to the handle and axially extending within and through both tubular members for engagement to a threaded nut fixedly mounted within the bore of the second tubular member and the underside of each tubular member including a track bar hook that can be hooked on to the cross bars of successive track sections of the endless track with clockwise rotation of the handle causing the telescoping retraction of the second tubular member for decreasing the distance between successive track sections and for increasing tension on the endless tracks and counterclockwise rotation of the handle for relieving tension on the tracks in order to facilitate the desired maintenance on the endless tracks.
