Description
If you’ve been noticing oil spots under your tractor or your rear axle housing’s got some seepage at the center section, this little o-ring might be the culprit. It’s one of those small parts that makes a big difference—sealing the connection between your rear axle housing and center housing to keep gear oil where it belongs and dirt and moisture out where they don’t.
What You’re Getting
- Precision-molded o-ring designed specifically for International Harvester axle housings
- Oil-resistant compound that won’t swell or deteriorate from gear oil contact
- Temperature-resistant material handles the heat cycles of hard work
- Direct replacement—same size and specifications as the original seal
Built for Real Farm Work
This o-ring fits a wide range of International Harvester tractors from the 4000 utility series through the big 7700 row-crop machines, spanning nearly two decades of production. These are the tractors that built their reputation on loader work, cultivating, and heavy field operations where axle integrity matters most.
Made to Last
Farm equipment seals face tough conditions—temperature swings from winter storage to summer field work, constant vibration, and exposure to gear oil and contaminants. This replacement uses modern rubber compounds that resist the hardening and cracking that eventually gets every seal after years of service.
Good to Know
When you’re replacing this seal, it’s a good time to check your gear oil level and condition. If the oil’s been leaking for a while, you might be running low. Clean the mating surfaces thoroughly before installing the new o-ring—any debris or old seal material will cause the new seal to leak.
