Description
When your hydraulic system starts feeling sluggish or you notice jerky operation on your loader or three-point hitch, it’s time to check that hydraulic filter. Dirty hydraulic fluid can destroy expensive pumps, valves, and cylinders faster than you’d think, especially on vintage tractors that put in long hours during busy seasons. This Baldwin PT461 filter element keeps your hydraulic system running clean and responsive when you’re counting on it most.
What You’re Getting
- 20 PSID bypass valve that keeps fluid flowing even when the filter’s working overtime
- Quality filter media that captures contaminants while maintaining proper flow rates
- Includes gasket and end seals for a complete installation – no hunting for extra parts
- Compact 4 3/16 inch length fits in tight filter housings without modification
- Baldwin quality construction that handles the temperature swings and pressure cycles of farm work
Built for the Classics
This filter element works in classic Allis Chalmers, Clark, International Harvester, Minneapolis-Moline, and Oliver tractors – machines that were built to last and are still earning their keep on farms today. Whether you’re running an old Allis WD-45 for hay work, an International Harvester for cultivating, or an Oliver for general farm duties, clean hydraulic fluid keeps these reliable workhorses operating smooth and strong.
Made to Last
Baldwin has been making filters for decades and knows what it takes to handle demanding conditions. The robust construction captures contaminants while maintaining proper fluid flow, protecting your tractor’s hydraulic components from premature wear. The bypass valve ensures your system keeps working even if the filter gets loaded up with debris during heavy use.
Installation Notes
This is a direct replacement element that installs in your existing filter housing. Drain the hydraulic system, remove the old element, and install the new one with the included seals. Change filters every 500-1000 hours depending on your operating conditions – more often if you’re working in dusty environments. Always use clean hydraulic fluid when servicing and check the old filter for unusual contamination.
