Description
When your old Massey Ferguson starts leaving oil spots where you park or you notice that familiar gear oil smell coming from the PTO area, it’s time to replace that worn PTO shaft seal. This seal maintains system pressure for optimal PTO performance while preventing environmental contamination from fluid leaks. A failing seal doesn’t just make a mess—it lets dirt and moisture into places they don’t belong while letting expensive hydraulic fluid leak out.
What You’re Getting
- High-quality nitrile rubber construction resists hydraulic fluid degradation and temperature extremes
- Double-lip design provides superior sealing against fluid leakage and contamination
- Spring-loaded seal maintains constant contact pressure for long-lasting performance
- Direct replacement that fits like the original—no modifications needed
- Exact 1-3/4 inch inner diameter and 2.685 inch outer diameter for a perfect fit
Built for Real Farm Work
This seal is designed for the classic workhorses that built American agriculture—your TO35, MF35, F40, MF50, and the early MF65, MF135, MF150, MF165, MF175, and MF180 tractors. These are the machines you see pulling bush hogs, running hay balers, and powering everything from post hole diggers to manure spreaders. They’ve been doing honest work for decades, and this seal keeps them running right.
Made to Last
Heat-resistant materials withstand PTO operating temperatures and heavy-duty use while maintaining flexibility in cold weather. The nitrile rubber construction handles the constant exposure to gear oil without swelling or cracking, and the spring-loaded design means it keeps sealing even as normal wear occurs.
Good to Know
You’ll want to drain the PTO housing before starting this job—it’s a lot cleaner that way. While you’ve got things apart, it’s a good time to check your PTO shaft for wear and clean out any debris that’s worked its way into the housing. The new seal installs just like the original, but take your time seating it properly to avoid damage to the seal lip.
