SF-Filter - HY20658 - Hydraulic Filter

This hydraulic filter element removes particulate contamination from the hydraulic oil before it circulates through the pump and control valves. It installs in the return-side filter housing of the tractor hydraulic system. A clogged element forces the bypass valve open, allowing unfiltered oil to reach downstream components and accelerate wear on spools and seals. The manufacturer machines the sealing surfaces to match the housing bore, ensuring the bypass valve seats correctly and opens only at the intended differential pressure. Replace the housing O-ring on reinstallation and torque the cap to specification.
