Description
There’s nothing quite like that sinking feeling when you spot oil pooling under your John Deere after it’s been sitting overnight. When that rear crankshaft seal starts to fail, you’re not just losing oil—you’re looking at potential bearing damage and expensive repairs if you let it go. This TISCO rear crankshaft seal gets your tractor sealed up tight so you can get back to work without worrying about what’s dripping onto the shop floor.
What You’re Getting
- Precision-engineered seal that handles the demanding job of containing oil pressure while the crankshaft spins thousands of times per minute
- TISCO quality construction built specifically for the heat cycles and vibration that destroy standard seals
- Rubber compound that resists hardening from temperature extremes and maintains flexibility season after season
- Direct replacement design that fits exactly like the original factory seal
Built for Real Farm Work
Your John Deere’s rear crankshaft seal has one of the toughest jobs in the engine, dealing with constant oil pressure, heat, and vibration while the crankshaft does its work. Whether you’re running a utility tractor for daily chores or powering through heavy field operations, that seal is working overtime to keep engine oil where it belongs and contaminants where they don’t.
Made to Last
TISCO seals are engineered for agricultural equipment that sees real hours under tough conditions. The advanced rubber compound won’t crack or harden like cheaper seals, and the metal housing maintains proper seal pressure even as your engine vibrates through thousands of hours of operation.
Installation Notes
Replacing a rear crankshaft seal means splitting the tractor between engine and transmission—it’s not a quick afternoon job, but it’s manageable with the right equipment. While you’re in there, check the crankshaft surface where the seal rides for any grooves or wear that could damage your new seal. Install carefully with a proper seal driver and apply a thin coat of oil to the seal lips before assembly.
