Oil Filter Components (1) Transmission oil filter bypass switch. (2) Bypass valve. (3) Oil filter base. (4) Oil inlet passage. (5) Oil outlet passage. (6) Housing. (7) Filter element.Oil flows into filter base (3) through inlet passage (4). The oil goes through the filter base to housing (6). Oil fills the space between the inside of housing (6) and filter element (7). The oil flows through the filter element and outlet passage (5). The oil then flows to the remainder of the hydraulic system. The filter element stops any debris that is in the oil.If the element becomes full of debris, the restriction to the flow of oil causes a pressure increase inside the filter. The increase in pressure causes bypass valve (2) to open. The oil then flows to the hydraulic system. When the filter element is dirty, the oil does not flow through the filter element. Debris in the oil that does not flow through the filter element can damage to other components in the hydraulic system.Bypass switch (1) is mounted in the base of transmission oil filter (3). Low pressure keeps the indicator light on the dash in the OFF position. High pressure turns the indicator light ON. The indicator light tells the operator that the filter element is plugged and the bypass valve is open.
