Location of flow control and relief valve for rear axle oil (1) Flow control and relief valve (2) Inlet line (3) Outlet lineThe control valve and relief valve (1) for the rear axle are located on the front of the rear axle housing and connected to the oil filter. Oil is pumped from the oil pump through inlet line (2) and into the control valve. Oil is sent to the final drives and oil is sent to the differential bevel gear through outlet line (3).

Flow control and relief valve (9) Relief valve (10) Outlet PassageControl valve (1) and relief valve (9) make up the bypass manifold. The bypass manifold directs the flow of oil to the final drive and the differential bevel gear. Inlet passage (7) receives oil from the oil pump for the rear axle. The oil is then sent through filter inlet (6). If the relief valve pressure in the filter has been exceeded the oil will bypass the filter with bypass valve (8). The oil is then sent through the passage for filter outlet (4) .Solenoid valve (1) controls the flow of the oil. Solenoid valve (1) will send the oil to the final drives and to the differential bevel gear, or solenoid valve (1) will bypass the final drives. Solenoid valve (1) will bypass the final drives in order to prevent the final drives from receiving too much oil. Solenoid valve (1) is controlled by the brake ECM. The brake ECM receives oil temperature readings from the oil temperature sensor that is located in the rear axle housing. The oil is then sent through outlet passage (10) to the final drives and differential bevel gear. If the final drive is bypassed the oil is sent to the differential bevel gear and to the rear axle housing. Cavity plug (5) is used only with an optional oil cooler.
