AGCO - 3800305M91 - Massey Ferguson Hydraulic Oil Filter

This hydraulic filter element removes particulate contamination from the oil circulating in the tractor's hydraulic system. It is installed in the filter housing on the pressure or return side of the hydraulic loop, protecting downstream components such as control valves, cylinders, and the pump from abrasive wear. A clogged element forces the system's bypass valve to open, allowing unfiltered oil to circulate and accelerating internal component wear. As an original-manufacturer component, the filter's sealing surfaces and bypass-valve cracking pressure are matched to the housing design, ensuring the bypass opens only when the element is fully loaded. When replacing the filter, clean the housing sealing surface and ensure the new element seats fully before tightening the cover.
