Description
If you’re noticing gear oil spots under your tractor or hearing more noise from the rear axle, it’s probably time to replace the outer half shaft seals. These seals keep your final drive oil where it belongs—inside the housing instead of leaking onto the ground. When they start to fail, you’ll lose lubrication and risk expensive damage to your differential and planetary gears.
What You’re Getting
- Precision 65x85x13mm dimensions for a perfect fit in your Case IH final drive housing
- Quality rubber construction that handles the heat, pressure, and vibration of daily farm work
- Metal outer case design ensures proper installation and long-term dimensional stability
- Direct replacement for the factory seal—no modifications or adapters needed
Built for Real Farm Work
This seal fits Case IH tractors from the compact 323 and 423 models up through the mid-size 640-940 series machines. Whether you’re running a smaller utility tractor for chores around the farm or a bigger row-crop machine for field work, this is the same seal design that came from the factory.
Made to Last
Farm equipment seals take a beating from temperature swings, contamination, and constant movement. This seal uses quality rubber that stays flexible through winter cold and summer heat, while the metal case keeps everything positioned correctly even after thousands of hours of operation.
Installation Notes
Replacing these seals requires removing the rear wheel and splitting the final drive housing—it’s a job that’s best done when you’re already working on the axle. Clean the seal bore thoroughly and check the half shaft for any wear or scoring that could damage the new seal. A light coat of grease on the seal lip helps it seat properly during installation.
