Abstract
An oil dam coupling for connecting an output shaft of a transmission arrangement to an input shaft of a pump assembly. The oil dam coupling includes a first member splined to the output shaft and a second member splined to the input shaft. The first member has an end plate which forms a cavity and retains oil within the cavity. The second member engages the first member within the cavity. The oil interacting between the first member and the second member within the cavity will reduce torsional wrap of the output shaft and reduce noise.
