When you notice transmission fluid spots where you park your Massey Ferguson or hear that telltale whine from low fluid levels, a worn input shaft seal is usually the culprit. This little seal keeps your transmission fluid where it belongs - inside protecting your gears and bearings - instead of dripping onto the ground or creating a mess that attracts dirt and debris. A small seal replacement now can save you from much bigger transmission problems down the road. What You're Getting Built to handle the constant rotation and pressure changes that input shafts experience during normal operation with quality seal material that maintains flexibility over a wide temperature range while resisting the chemicals and additives found in modern transmission fluids Prevents dirt and moisture from entering your transmission, which could cause premature wear and expensive internal damage Direct replacement seal designed specifically for 6-speed transmissions on these classic Massey Ferguson models Proper fit ensures reliable sealing without leaks or premature failure Built for Real Farm Work This seal fits your workhorse Massey Ferguson tractors from the dependable 35 series through the powerful 100 series models. These tractors have been handling everything from hay cutting and cultivating to loader work around the farmyard for decades, and their transmissions need proper sealing to keep operating reliably season after season. Made to Last This oil seal is engineered to handle the constant rotation and pressure changes that input shafts and drop box components experience during normal operation. The quality seal material maintains flexibility over a wide temperature range and stands up to the harsh conditions these tractors face every day. Installation Notes Oil seal replacement typically requires removing the input shaft or related components, so consider having this work done during other transmission service to save on labor costs. Always clean the seal bore thoroughly and check the shaft for wear or damage before installing the new seal.
