Description

If you’ve ever caught that unmistakable smell of engine oil mixing with hot exhaust or noticed spots under your tractor after parking it in the barn, you know the frustration of a leaking rear crankshaft seal. This little seal sits where your engine crankshaft meets the flywheel housing, and when it starts to fail, oil leaks right onto your clutch and transmission—a problem that’ll only get worse if you don’t fix it.

What You’re Getting

Quality rubber seal designed to handle the constant rotation and heat of the crankshaft
Precise fit prevents oil from contaminating your clutch assembly
Durable construction that holds up to temperature extremes and vibration
Direct replacement design makes installation straightforward with basic tools

Built for Real Farm Work

This seal fits a range of International Harvester and Farmall tractors that have been the backbone of American farming for decades. Whether you’re running an older utility tractor for chores around the farm or operating a row-crop machine during planting season, this seal keeps your engine oil where it belongs—inside the engine instead of dripping onto your shop floor.

Made to Last

Farm equipment seals take a beating from constant heat cycles, vibration, and exposure to various fluids. This rear crankshaft seal is manufactured from oil-resistant rubber compounds that maintain their flexibility and sealing ability even after thousands of hours of operation. The reinforced design prevents the seal lip from rolling or tearing during installation.

Installation Notes

Replacing this seal requires removing the transmission and flywheel, so it’s often done during clutch work or engine rebuilds. Take your time during installation—a crooked seal will leak from day one. A thin coat of engine oil on the seal lip helps it slide into position without damage, and make sure the crankshaft surface is smooth and clean before pressing the new seal home.
