The retainer (92) is fixed in a longitudinal direction with respect to the hub (46) and is movable in a radial direction for allowing mounting of a drive roll onto the hub (46). An outer end of the lug (60) may include an alignment segment that has a different profile shape than the rest of the lug (60) to facilitate alignment of a mounting groove of the drive roll with the lug (60).
