Disposed outboard from the bearing journal surface is a bearing and a tapered roller bearing is disposed outboard from the tapered roller bearing journal surface of the input shaft. At least a portion of the tapered roller bearing is disposed with a tapered roller bearing receiving portion circumferentially extending along at least a portion of an inner surface of an input helical side gear.
