The idler shaft, which extends through the idler gear and supports the idler gear for rotation, includes an interior chamber, an outer surface, and a wall. A portion of the outer surface is formed with a clearance space, into which space a portion of the ring gear extends and rotates. The clearance space communicates through the wall to the chamber, the wall being formed with a hydraulic passage, which carries lubricant from the chamber to the outer surface.
