This hydraulic filter element removes particulate contamination from the oil circulating in the hydraulic system of the host harvesting machine. It is installed in the return line, where it captures wear debris from pumps and actuators before the fluid re-enters the reservoir. A clogged element forces the system’s bypass valve open, allowing unfiltered oil to recirculate, which accelerates wear on downstream components. As an original-manufacturer part, its sealing dimensions match the filter housing, preventing bypass leakage at normal operating pressure. Replace the housing O-ring during installation and tighten the cap to the specified torque.
