Description
There’s nothing quite like that sinking feeling when you spot oil dripping from your tractor’s timing cover. Whether you’re running a utility tractor for livestock operations or powering through field work, that front crankshaft seal is all that stands between your engine oil and the outside world. When it starts leaking, you’re not just losing oil—you’re looking at potential bearing damage and costly repairs down the road. This TISCO replacement seal gets your International Harvester tractor sealed up tight and ready for work.
What You’re Getting
- Quality TISCO construction designed specifically for farm use and heavy-duty applications
- Built from materials designed specifically for farm use, handling the heat cycles and vibration that destroy standard seals
- Quality construction that maintains proper seal pressure even as it wears in
- Direct replacement that restores proper sealing between the crankshaft and timing cover
- Proven materials that hold up to hundreds of hours between oil changes and the harsh conditions farm equipment faces
Built for Real Farm Work
This seal fits International Harvester and Farmall tractors where the crankshaft exits the timing cover area. These engines see plenty of hours under varying conditions, and the front crankshaft seal takes the brunt of that abuse where the spinning crankshaft exits the timing cover. From smaller utility tractors working around the farmstead to larger row-crop machines running long hours during planting and harvest, this is where engine oil meets the real world.
Made to Last
TISCO seals are built to handle the demanding conditions of agricultural equipment. The rubber compound resists hardening from heat and cold cycles, while the metal housing maintains a tight fit even as the engine vibrates through thousands of hours of operation. This isn’t just another seal—it’s engineered to handle what farm life throws at it.
Installation Notes
Installing a front crankshaft seal typically means removing the timing cover, so plan for a few hours of work. Clean the seal bore thoroughly and check the crankshaft surface for wear grooves—even minor scratches can cause a new seal to leak. Use a proper seal driver to install it square and even, and always apply a thin coat of clean engine oil to the seal lip before installation. Taking your time on installation saves headaches later.
