This hydraulic oil filter element is installed in the gearbox circuit of the host tractor, where it removes particulate contamination from the hydraulic fluid before it reaches the transmission and implement control valves. The filter assembly threads into the gearbox housing and uses a bypass valve to maintain flow if the element becomes fully loaded. A clogged filter causes sluggish hydraulic response and can lead to valve sticking or pump cavitation. Mann-Filter manufactures this element to match the original seal geometry and bypass cracking pressure, ensuring that the filtration system operates within the design parameters of the gearbox. When replacing the element, clean the housing sealing surface and torque the filter canister to the specified value.
