When your PTO starts dripping oil under the tractor or you notice transmission fluid getting low without any obvious leaks, there's a good chance your PTO output seal is the culprit. These seals prevent hydraulic fluid leakage that could contaminate the environment and compromise system performance while ensuring optimal PTO efficiency for maximum implement performance . This 50x80x10mm seal keeps transmission oil where it belongs and prevents dirt and debris from getting into your PTO housing. What You're Getting Precision-molded 50x80x10mm dimensions for exact fit on your PTO output shaft Precision-engineered design ensures consistent sealing pressure throughout the operating temperature range, with superior material properties that resist degradation from exposure to hydraulic fluids, heat, and pressure cycling Quality rubber compound that handles the demands of daily farm use Direct replacement that installs just like the original factory seal Built for Real Farm Work This seal fits a wide range of Ford New Holland utility tractors from the compact 30 series machines up through the larger TD and TL series workhorses. Whether you're running a loader, powering a hay baler, or operating a brush hog, these tractors see plenty of PTO work in farming, ranching, and property maintenance operations. Made to Last PTO systems work hard, with constant rotation at high speeds and varying loads that create heat and pressure that can destroy inferior seals. This seal uses quality rubber compounds specifically designed for transmission fluid exposure and the temperature extremes that PTO components face during normal operation . Installation Notes You'll need to access the PTO housing to replace this seal, which typically means removing the PTO shield and possibly dropping the PTO assembly depending on your tractor model. Clean the shaft and housing thoroughly before installation, and apply a thin coat of gear oil to the seal lip to prevent damage during initial startup.
