Description
When you notice gear oil creeping forward onto your clutch, you’re looking at trouble that’ll only get worse. This main drive spigot shaft seal sits between your transmission and clutch housing, keeping gear oil where it belongs so your clutch can do its job without slipping all over the place.
What You’re Getting
- Precision-sized at 57.2mm x 27/29mm x 9.6mm for an exact fit on single clutch models
- High-quality seal material that stands up to gear oil and operating temperatures
- Direct replacement that stops oil contamination before it ruins your clutch disc
- Proper seal design maintains transmission oil pressure while protecting clutch components
Built for Real Farm Work
Your Massey Ferguson 35, 135, or 240 with single clutch setup is perfect for running bush hogs, operating loaders, or pulling cultivation equipment around smaller operations. These tractors were built simple and reliable, but when this little seal fails, gear oil migrates forward and turns your clutch disc into a slippery mess that won’t grab no matter what.
Made to Last
This seal handles the constant heat and pressure where your transmission meets the clutch housing. The seal material resists breaking down from gear oil contact and maintains its sealing properties through temperature changes and vibration that come with regular farm use.
Installation Notes
Getting to this seal means splitting the tractor between transmission and clutch housing—it’s not a quick roadside fix, but it’s essential clutch work. Clean the spigot shaft thoroughly and check for wear grooves before installing the new seal. Use proper seal drivers and never hammer directly on the seal itself. If you’re doing this job because of clutch contamination, plan on replacing the clutch disc too—once oil soaks in, there’s no saving it.
