This hydraulic filter element is an original part from the manufacturer AGCO. It is installed in the return line of the hydraulic system, where it captures particulate contamination before the fluid re-enters the main pump circuit. A clogged or bypassed element allows unfiltered fluid to circulate, which can accelerate wear on control valves and actuators. The filter housing uses a seal that must be replaced during service to prevent air ingress. Torque the housing cap to specification on reinstallation.
