If you've noticed wet spots under your tractor or heard a whining noise from the transmission, there's a good chance one of the seals in your Multi-Power transmission is calling it quits. This seal is designed for the PTO pinion shaft retainer in Massey Ferguson's Multi-Power transmission system, and when it fails, you'll lose hydraulic fluid and potentially damage expensive transmission components. Getting the right seal installed means keeping your power flow smooth and your transmission running like it should. What You're Getting Precision-molded seal with 1.58" ID and 1.945" OD dimensions that matches factory specifications exactly Heavy-duty construction built to handle the pressures and temperatures inside your Multi-Power transmission Direct replacement design that installs without modifications or special tools Red seal material specifically engineered for transmission fluid compatibility Quality that keeps transmission fluid where it belongs—inside the case, not on your shop floor Built for Real Farm Work This seal fits a wide range of Massey Ferguson tractors that came equipped with the Multi-Power 12-speed transmission system. From the smaller 100 series utility tractors up through the powerful 600 series row-crop machines, these tractors have been the backbone of countless farming operations for decades. Whether you're running a 135 for hay work, a 265 for crop farming, or a 390 for heavy field preparation, the Multi-Power transmission gives you the gear range flexibility that makes these tractors so versatile. Made to Last Transmission seals take a beating from constant pressure, temperature changes, and the demanding nature of farm work. This seal is manufactured from materials specifically chosen to resist transmission fluid degradation while maintaining the flexibility needed to create a reliable seal. The WRG125 specification ensures you're getting a seal that meets the original engineering requirements for your Multi-Power transmission. Installation Notes This is a straightforward replacement that any competent mechanic can handle. Clean the seal bore thoroughly before installation, and take your time to get the new seal seated squarely—a cocked seal won't do its job. Keep some fresh transmission fluid handy to top off the system after you're done, and check for leaks after a few hours of operation.
When you're in the middle of clutch work or transmission service, finding transmission oil where it shouldn't be is never good news. A leaking input housing seal lets precious hydraulic fluid escape while letting dirt and moisture find their way into your transmission. This complete seal kit stops those leaks at the source and keeps your Massey Ferguson's transmission protected from contamination that can cause expensive internal damage down the road. What You're Getting Complete set of seals specifically for the 42S input housing design Quality materials that handle transmission pressure and temperature swings Direct replacement seals that match original equipment specifications Professional-grade gaskets and O-rings that maintain proper sealing under field conditions Built for Real Farm Work This seal kit fits both Massey Ferguson 300 series and 4200 series tractors that use the 42S input housing configuration. These versatile machines handle everything from cultivation and planting to loader work and hay production. The 300 series tractors are popular for their reliability in row crop farming, while the 4200 series provides the extra horsepower needed for heavier implements and more demanding field operations. Made to Last Farm transmissions work hard under constantly changing loads and conditions. These seals are manufactured from compounds that resist breakdown from hydraulic fluids and temperature extremes. They're designed to maintain their sealing properties through thousands of hours of operation, protecting your transmission investment. Good to Know This is typically transmission-out work that's best done when you're already splitting the tractor for clutch service or other major repairs. While you've got everything apart, it's the perfect time to replace these seals rather than risk contaminating new clutch components later. Always clean the housing surfaces thoroughly and check for scoring that could prevent proper sealing.
