Description
That gear oil pooling under your rear wheel isn’t just making a mess—it’s a warning that your outer axle seal has given up the fight. When this seal fails, you’re not just losing expensive gear oil; you’re inviting dirt and moisture into your rear end that can destroy bearings, gears, and brakes. This outer seal and retainer assembly does the heavy lifting at the wheel end, keeping everything sealed up tight so your tractor stays reliable when there’s work to be done.
What You’re Getting
- Complete seal and retainer assembly that installs as one unit—no guessing about alignment
- Heavy-duty construction designed to handle the constant rotation and pressure of farm work
- Quality materials that resist breakdown from heat, cold, and gear oil exposure
- Direct replacement for your original equipment—fits right where the old one came out
- Integrated design eliminates the potential leak points of separate components
Built for Real Farm Work
This assembly fits the workhorse Ford tractors that are still earning their keep on farms everywhere—the reliable 4000 and 4600 series utility tractors, plus the 3910, 4100, 4110, and 4610 models. These are the tractors pulling bush hogs through pastures, running loaders all day, and handling the thousand tasks that keep a farm operation running. The rear axle takes serious abuse from heavy loads and constant turning, which is why a proper seal is crucial.
Made to Last
Farm equipment seals have to deal with more than just oil pressure—they face temperature swings, vibration, dirt, and the occasional bump from implements or obstacles. This assembly is built to handle those real-world conditions with materials and design that hold up to the punishment. The integrated retainer ensures the seal stays positioned correctly even under heavy loads.
Good to Know
Installation means pulling the wheel and working around brake components, so plan on a few hours and have your gear oil ready for refilling. Clean everything thoroughly during installation—any dirt or debris will cause the new seal to fail quickly. Check your axle shaft for grooves or wear where the seal rides, and polish out any minor imperfections with fine emery cloth before installing the new assembly.
