This hydraulic filter element is installed in the hydraulic pump circuit of self-propelled forage harvesters. It removes particulate contamination from the fluid before it enters the pump, protecting downstream components such as valves and actuators from abrasive wear. When the element becomes clogged, the system may experience reduced flow or bypass, allowing unfiltered fluid to circulate and accelerate internal pump wear. The manufacturer constructs this element to match the original housing dimensions, ensuring proper sealing and correct bypass-valve operation. Replace the housing seal during installation and torque the cap to specification.
