This hydraulic oil filter removes particulate contamination from the fluid circulating in the tractor's hydraulic system. It is installed inside the hydraulic tank, where it captures wear debris and other solids before they can reach the pump and control valves. A clogged filter element forces the bypass valve to open, allowing unfiltered fluid to pass downstream and accelerate wear on precision components. As an original-manufacturer part from AGCO, the filter element matches the housing's internal seal geometry and bypass-valve cracking pressure, so the system maintains its designed filtration efficiency. Replace the tank gasket when reinstalling the filter head.
