(10) Housing Oil from the hydraulic oil tank flows to the oil pump. The parking brake release section of the pump sends oil to parking brake release hydraulic filter (1).Oil flows through inlet passage (8). The oil fills the space between the inside of housing (10) and element (9). During normal operation, the oil flows through element (9) and out outlet passage (6) to the remainder of the hydraulic system. Element (9) stops any debris that is in the oil.If filter element (9) becomes full of debris, the restriction to the flow of oil causes a pressure increase inside the filter. The pressure oil causes bypass valve (4) to move against the force of spring (5). Also, bypass switch (2) will be activated and an alarm will be registered in the cab.The oil then flows past the open bypass valve and to the remainder of the hydraulic system. When the oil does not flow through the filter element, the debris in the oil will cause damage to other components in the hydraulic system.Use correct maintenance in order to make sure that element (9) does not become full of debris. If element (9) is full of debris, the flow of clean oil to the hydraulic system is stopped.
