A driving member engages one end face, a driven member engages the other end face, and a through-bolt extends through the inner bore of the inner race for clamping the driven member, inner race and driving member together. An auxiliary assembly sleeve is connected to one of the driving or driven members and fitted over the through-bolt, the sleeve being in friction-tight engagement with the inner bore of the inner race.
