(1) Case drain oil filter (2) Base (3) Inlet passage (4) Outlet passageCase drain oil filter (1) returns case drain oil to the hydraulic tank from the hydraulic fan pump and the hydraulic fan motor. Oil flows through inlet passage (3). During normal operation, the oil flows through case drain oil filter (1) and back to filter base (2). Oil flows out outlet passage (4) to the hydraulic tank. Case drain oil filter (1) stops any debris that is in the oil.If case drain oil filter (1) becomes full of debris, the restriction to the flow of oil causes a pressure increase inside case drain oil filter (1). The pressure of the oil causes the bypass valve in base (2) to open. The oil then flows past the open bypass valve to the hydraulic tank. When the oil does not flow through case drain oil filter (1), the debris in the oil will contaminate the hydraulic oil in the hydraulic system.Use correct maintenance in order to prevent case drain oil filter (1) from becoming full of debris. If case drain oil filter (1) becomes full of debris, the flow of filtered oil to the hydraulic tank is stopped.
