What Does A Track Spring Or Track Tensioner Assembly Do? The track spring assembly allows for the tension of a track to be controlled and for impacts to the undercarriage to be absorbed by the recoil spring without the force of the impact affecting sensitive parts on the machine like final drives and sprockets.
