This hydraulic filter element removes particulate contamination from the oil circulating in the tractor's hydraulic system. It is installed in the housing located on the gearbox or hydraulic system, where it protects downstream components such as pumps and control valves from abrasive wear. As the element becomes loaded with debris, the differential pressure across the filter rises; if the element is not replaced at the correct interval, the internal bypass valve may open, allowing unfiltered oil to circulate and accelerate wear in the system. The filter uses a threaded connection (M42) for secure mounting to the housing. When reinstalling, ensure the housing sealing surfaces are clean and the filter is torqued to the manufacturer's specification to prevent leaks.
