A lubrication flow control mechanism for a power transmission includes a bearing member and a spring biasing the bearing member in a direction. The bearing member and the spring cooperate to sufficiently restrict flow past the bearing to cause increased fluid flow to a lubrication-requiring member located downstream of the bearing. A method of limiting lubrication flow in a transmission is also provided.

Lubrication flow control mechanism and method

A transfer gear assembly includes a transfer gear rotatably supported directly by a tapered roller bearing and thrust bearing. A tapered snap ring is positioned in a circumferential groove on a hub to provide a preload on the tapered roller bearing and thrust bearing. The tapered roller bearing and thrust bearing each may include only a single race.
