Abstract: A driveline assembly for an engine is disclosed. The engine has an engine damper and a base frame. The engine is mounted on the base frame. The driveline assembly includes a torsional coupling that has alternating wedge portions of first wedge portions and second wedge portions. The first wedge portions include a rigid structure. The second wedge portions include a resilient structure. A guide assembly includes at least one pillow block mounted to the base frame. Further, a driveshaft is included that has a first end and a second end. The first end is connected to the engine damper via the torsional coupling. The driveshaft is rotatably supported by the pillow block. Moreover, the first wedge portions include radially extending fasteners to capture an outer portion of the first end of the driveshaft. Further, a belt drive with a drive pulley is connected to the second end of the driveshaft.
