(6) Suction screen Gear pump (1) which provides lubrication oil to the rear axle is driven by hydraulic motor (2). The motor and the pump are connected by coupling (5) that is located in adapter (4). Hydraulic motor (2) is driven by fluid from the steering pump. This means that the rear axle can receive oil if the vehicle is at a stop or if the vehicle is moving. Oil flow is directed to pump motor (1) when the supply solenoid is OFF. Oil flow is blocked to gear pump (1) when the supply solenoid is ON.Gear pump (1) pulls oil from the bottom of the rear axle housing through suction screen (6). The oil flows through the oil filter for the rear axle. Then, the oil flows through the final drive bypass manifold. The oil is directed to the final drives and the bevel gear. The oil is also distributed to the bearings of the rear wheels.
