This hydraulic oil filter removes particulate contamination from the hydraulic circuit before the fluid reaches the pump and control valves. It is installed in the return line housing of the tractor's hydraulic system, where it captures wear debris from actuators and motors. A clogged filter element forces the bypass valve open, allowing unfiltered oil to circulate and accelerate pump and valve wear. Manufactured by Agro-Hytos, the filter element matches the housing's seal geometry and bypass-valve cracking pressure, ensuring the system maintains proper filtration until the element is fully loaded. Replace the housing seal and torque the cap to specification on reinstallation.
