Description
When you spot oil puddles under your Massey Ferguson or notice the transmission fluid level dropping faster than usual, there’s a good chance this input seal has given up the ghost. This input shaft seal keeps your transmission fluid where it belongs while preventing dirt and moisture from contaminating your transmission system, and when it starts leaking, small problems can turn into major transmission headaches. Getting this seal replaced before things get worse saves you from much costlier repairs down the road.
What You’re Getting
- Quality rubber construction that’s specifically designed for transmission fluid exposure and temperature extremes, with a spring-loaded lip design that maintains proper sealing pressure
- Precise 41.4mm outer diameter, 27.3mm inner diameter, and 10mm width dimensions for an exact fit
- Proper sealing that keeps contamination out of your transmission, protecting expensive gears and bearings from dirt and moisture damage
- Direct replacement that stops fluid leaks and prevents low fluid levels that can damage transmission components
Built for Real Farm Work
This seal fits a wide range of Massey Ferguson tractors from the compact 100 series utility models up through the bigger 600 series and 4200-4300 series machines. Whether you’re running a 135 on chores, pulling implements with a 265, or handling heavy work with a 4355, this is the same quality seal that keeps transmission fluid where it should be across the entire MF lineup.
Made to Last
Transmission systems work hard with constant rotation at high speeds and varying loads that create heat and pressure, so this seal uses quality rubber compounds engineered to handle these demanding conditions. The spring-loaded design maintains consistent sealing pressure even as normal wear occurs, preventing the gradual leaks that slowly drain your transmission.
Installation Notes
Transmission input seal replacement typically requires removing the input shaft or related components, so clean the seal bore thoroughly and inspect it for scratches or damage that could cause the new seal to leak. Apply a thin coat of transmission fluid to the seal lip before installation to prevent damage during assembly, and make sure the dimensions match your shaft and housing exactly for proper sealing.
