That oil seepage around the front of your engine isn't just making a mess - it's telling you the timing cover seal has given up the fight. When you start seeing oil traces where the timing cover meets the crankshaft, this 55x84x13mm seal often provides the fix without tearing into major engine components. It's one of those simple parts that saves you from bigger headaches down the road. What You're Getting Exact 55mm inner by 84mm outer dimensions for proper fit every time Double-lip design that keeps oil in and dirt out better than single-lip seals Steel reinforcement prevents distortion under crankshaft pressure and vibration Heat-resistant materials that handle the temperature swings of diesel engine work Direct replacement that installs with basic tools - no modifications needed Where This Part Shines Your John Deere 10 or 20 series tractor puts in long days whether you're running a compact utility model for chores or depending on the bigger machines for serious field work. The timing cover area sees constant stress from crankshaft rotation, temperature changes, and the general beating that comes with farm life. This seal keeps critical engine oil where it belongs while preventing contamination that destroys expensive timing components. Made to Last This isn't just any rubber ring - it's engineered specifically for the demands of agricultural engines. The seal material stays flexible through temperature extremes while resisting breakdown from hot engine oil. The steel backing prevents the seal from distorting under pressure, and the precision-molded lips maintain consistent contact with rotating surfaces for years of reliable service. Installation Notes Clean the timing cover housing thoroughly before installation and check that crankshaft sealing surface for any grooves or rough spots that'll chew up a new seal. Use a proper seal driver to seat it square and at the correct depth - never hammer directly on the seal itself. A light coating of clean engine oil on the seal lips helps with initial startup and extends seal life.
