Description
There’s nothing more aggravating than finding hydraulic fluid puddles under your tractor or smelling that telltale leak smell coming from the PTO area. When your PTO shaft seal starts going, you’re not just losing expensive fluid—you’re risking contamination of your clutch and transmission that can lead to costly repairs. This replacement seal gets you back to leak-free operation and protects the heart of your PTO system. This handy pack of 10 O-rings means you’ll have what you need when those seals start weeping around the PTO shaft.
What You’re Getting
- Pack of 10 high-quality O-ring seals for better value and convenience
- Precision-molded rubber construction that handles temperature swings and pressure cycles
- Proper dimensions designed for reliable sealing around PTO shaft applications
- Quality materials that resist hydraulic fluid, gear oil, and the elements your tractor faces
- Direct replacement seals that restore factory-level sealing performance
Built for Real Farm Work
These O-rings fit Massey Ferguson 56, 57, 67, and 77 series tractors—workhorse machines that spend their days powering hay balers, brush hogs, mowers, manure spreaders, and post hole diggers. Whether you’re running a 135 on hay duty, pulling a rotary cutter with a 274, or operating a baler with a 394, these are the tractors that power essential implements like mowers, balers, spreaders, tillers, and post hole diggers across thousands of farms. These seals handle the demanding job of keeping hydraulic fluid where it belongs while your PTO system transfers power to your implements.
Made to Last
PTO seals take serious abuse from constant rotation, pressure cycling, and temperature swings that destroy inferior seals. These O-rings are built with quality rubber compounds that stand up to the hydraulic fluids, temperature extremes, and vibration that come with real farm work. Buna-N rubber stands up to the hydraulic fluids, diesel fuel, and weather conditions your equipment faces every day.
Installation Notes
Clean the PTO shaft and housing thoroughly before installation—any dirt or old seal debris will cause the new seal to leak. Apply a thin coat of transmission fluid to the seal lip before installation to prevent damage during assembly. Use proper seal installation tools to avoid nicking the seal during fitting, and always inspect the shaft for wear grooves that could compromise the new seal. Having 10 seals on hand means you can tackle multiple repairs or keep spares in the shop for when you need them most.
