If you've noticed your three-point hitch acting sluggish, your loader getting jerky, or that whining noise from the hydraulic pump getting worse, chances are your hydraulic filter needs attention. This MK1 hydraulic filter element keeps your Massey Ferguson's hydraulic system running clean and smooth, protecting those expensive pumps and valves from the dirt and metal particles that can turn a small problem into a big repair bill. What You're Getting High-efficiency filtration that catches particles down to microscopic levels - stops problems before they start Pleated design that maximizes surface area so the filter lasts longer between changes Exact 98mm x 64mm dimensions for a perfect fit in MK1 pump housings Heavy-duty construction that handles hydraulic pressure surges without collapsing Direct replacement that works with all standard hydraulic fluids and additives Built for Real Farm Work These classic MF tractors like the 135, 165, and 185 are some of the most dependable machines ever built - that's why you still see them working every day on farms across the country. Whether you're using yours for loader work, running implements off the three-point, or powering hydraulic remotes, clean oil is what keeps everything working when you need it most. Made to Last Your hydraulic system operates under serious pressure, and this filter element is built to handle it. The pleated media stays strong even when oil gets hot during heavy work, and the construction won't break down from temperature swings or the additives in modern hydraulic fluids. Installation Notes You'll need to relieve hydraulic pressure before swapping the element - just cycle your implements with the engine off to bleed down pressure. While you've got the housing apart, it's a good time to check the condition of your seals and top off with fresh hydraulic oil if needed.
