Description
Nothing ruins a perfect day of baling hay quite like discovering gear oil has leaked into your brake housing, turning your dry disc brakes into a slippery mess. This inner half shaft seal fits Massey Ferguson 100 series tractors with dry brake systems, creating the crucial barrier between your transmission oil and brake components that keeps you stopping when you need to.
What You’re Getting
- Precision-molded rubber construction that maintains a tight seal between transmission and brake housing
- Specifically sized for dry brake systems – won’t work with wet brake models, so you know it’s the right fit
- Heavy-duty materials that handle the constant rotation and heat from your differential
- Direct replacement that installs just like the original factory seal
Built for Real Farm Work
The Massey Ferguson 135 was one of the most popular tractors of the era, with these versatile workhorses essential for diverse farming operations including crop cultivation, hay production, livestock farming, and field preparation. Whether you’re running a 135 around the farm, using a 165 for heavier field work, or operating a 595 on bigger acreage, these reliable tractors depend on proper sealing to keep their brake systems working safely.
Made to Last
This seal uses specialized rubber compounds designed to withstand the demanding conditions inside your rear axle. The precise dimensions ensure a snug fit on the half shaft while maintaining constant pressure against the housing bore. Unlike generic seals that might work for a while, this one’s engineered for the unique requirements of Massey Ferguson’s dry disc brake design.
Installation Notes
Before you install the new seal, always check your brake surfaces for oil contamination – if there’s already oil damage, you’ll need to service the entire brake system. Clean the half shaft thoroughly and inspect for any grooves worn by the old seal. A light coating of grease on the seal lip helps during installation and prevents damage during startup. Remember to keep that drain hole at the bottom of the brake housing clear so any minor seepage can escape instead of pooling where it can damage your brakes.
