That steady drip under your John Deere isn't just messy—it's expensive oil walking away from your engine and heading straight for your clutch. When your rear crankshaft seal gives up, you're looking at contaminated clutch discs, low oil levels during long field days, and a repair bill that keeps growing. This replacement seal stops the leak right at its source and keeps your oil where it belongs. What You're Getting Precision dimensions at 118mm ID x 146mm OD x 14.3mm width for exact factory fit Advanced lip design that maintains proper sealing pressure as it wears Heat-resistant materials that won't crack or harden from hot oil exposure Steel-reinforced construction prevents distortion during installation Wide sealing surface provides reliable protection against high-pressure leaks Built for Real Farm Work This seal handles the demanding job of keeping engine oil contained while your crankshaft spins thousands of times per minute. Whether your 40 series handles daily chores around the farmyard, your 50 series powers through heavy field work, or your 6000 series runs loaded implements all season long, this seal deals with constant heat, pressure, and vibration without backing down. Made to Last The rear crankshaft location is one of the toughest spots in your engine—high speeds, hot oil, and relentless pressure test every component. This seal uses premium compounds that resist hardening and cracking, while the reinforced construction prevents the distortion that kills cheaper seals. You'll get reliable protection season after season. Installation Notes Plan on splitting the tractor between engine and transmission—this isn't a quick roadside fix, but it's straightforward work with the right equipment. Check your crankshaft surface for grooves or wear before installing the new seal, and use a proper seal driver to avoid crooked installation. A thin coat of oil on the seal lip helps it seat properly and extends its life.
