Abstract
A power transmitting component having a first shaft and a pump. The first shaft has a longitudinal bore, a pump mount and a feed conduit. The pump mount has a circumferentially extending surface, a drive portion and a channel that extends circumferentially about the first shaft. The channel is disposed along a longitudinal axis of the first shaft between the drive portion and the circumferentially extending surface. The feed conduit intersects and fluidly couples the longitudinal bore and the channel. The pump has a pump housing, a first rotor and a pump outlet. The pump housing is mounted about the circumferentially extending surface and is disposed circumferentially about the channel. The first rotor is coupled to the drive portion for rotation therewith. The pump outlet is coupled in fluid communication with the channel.
