Description
When you see that telltale oil puddle forming under your TM’s front axle, don’t ignore it—that drop box seal failure can turn into a costly front drive rebuild if you let it go. This seal sits right where power transfers from the transmission to your front wheels, keeping gear oil in and dirt out. At 12mm thick, this little seal carries a big responsibility, protecting thousands of dollars worth of gears and bearings that make your four-wheel drive work when you need it most.
What You’re Getting
- Precise 40x80x12mm dimensions for perfect factory fit in your drop box housing
- Double-lip design seals tight against both oil leaks and contamination
- High-grade rubber compound that won’t swell or crack from gear oil additives
- Spring-loaded lip maintains sealing pressure even as normal wear occurs
- Direct replacement part—no modifications or special tools required
Built for Real Farm Work
Your TM series tractor delivers serious horsepower for intensive farming operations, from the 115-hp TM115 up to the big TM190. Whether you’re pulling deep tillage through tough ground, operating a heavy loader in the feedyard, or navigating steep terrain, that front axle drive system works hard. The drop box transfers all that torque to the front wheels, and it needs proper lubrication to handle the load without expensive failures.
Made to Last
This seal uses compounds specifically formulated for modern gear oils with EP additives that can destroy standard seals. The metal case prevents distortion under pressure, while the rubber lip profile maintains contact even as shafts develop minor wear patterns. The garter spring ensures consistent sealing pressure throughout the seal’s service life, not just when it’s new.
Installation Notes
Take your time with this job—clean the seal bore thoroughly and check the shaft for wear grooves before installing the new seal. Use a proper seal driver to install it perfectly square in the housing. Never hammer directly on the seal itself, and always coat the sealing lip with clean gear oil before installation. Even slight misalignment will cause immediate failure, so patience pays off here.
