Description
If you’ve been finding puddles of transmission fluid under your Ford 4000 or Dexta, chances are good it’s this seal that’s given up the ghost. A worn PTO input shaft seal doesn’t just make a mess—it’s slowly draining your transmission of the fluid that keeps those dual clutch components happy. When your PTO starts acting up or you notice slippery spots around the tractor, it’s time to swap this seal before a small leak becomes a big problem.
What You’re Getting
- Exact 1.93″ x 3.12″ x 0.48″ dimensions for a perfect fit on your spigot shaft
- Spring-loaded lip that maintains steady sealing pressure even as it wears
- Heat-resistant rubber compound that handles the temperatures your PTO generates
- Direct replacement that goes in without modifications or adapters
- Quality construction that keeps transmission fluid where it belongs
Built for Real Farm Work
Ford 4000 series and Dexta tractors with dual clutch setups were workhorses in their day, and many are still earning their keep on farms today. These machines excel at loader work, mowing, and running PTO implements where you need that independent clutch action. The dual clutch design lets you engage the PTO without stopping forward motion—handy when you’re running a mower or baler and need to keep moving.
Made to Last
This seal is built to handle the constant rotation and pressure changes that come with PTO work. The nitrile rubber construction resists breakdown from transmission fluid exposure, while the metal case provides the structural strength to stay put in the housing. It’s designed to maintain that critical seal between your transmission and the outside world.
Good to Know
Installing this seal means splitting the tractor to access the PTO input area—it’s not a quick roadside fix. While you’re in there, inspect the spigot shaft for wear grooves that could cause your new seal to leak. Clean everything thoroughly and use a proper seal driver to avoid damaging the new seal during installation.
