Oil flows from the differential and bevel gear case through the magnetic screen and to the transmission oil pump. The transmission oil pump delivers oil through inlet passage (2) to the oil filter.The oil fills the space between housing (6) and element (1). The oil normally flows through the element and exits through outlet passage (3) to the selector valve. The element blocks debris that is in the oil.If element (1) becomes full of debris, the restriction to oil flow causes a pressure increase. The pressure causes bypass valve (4) to move against the force of spring (5). The oil bypasses the element and flows directly from inlet passage (2) to outlet passage (3). When the oil bypasses the element, debris in the oil will cause damage to other system components. Proper maintenance must be used in order to ensure that the flow of the oil through the element is not restricted by excessive debris.
