Genuine Rear Crankshaft Oil Seal for Ford Escape 2005-2013 2.3 LF0111310

Genuine rear crankshaft oil seal for Ford Escape 2005-2013 2.3 engine, part number LF0111310 is an important component of the engine lubrication system. It seals the rear end of the crankshaft at the interface between the engine and transmission. The seal helps prevent engine oil from leaking while ensuring the crankshaft rotates smoothly at high speed, helping maintain oil pressure and protect internal engine parts.

On the Ford Escape 2005-2013 2.3 engine, the rear crankshaft oil seal works in sync with the crankshaft, flywheel or Flexplate, transmission, crankshaft bearings and lubrication system to keep engine oil sealed inside the sump. When the seal is working properly, oil does not leak at the joint between the engine and transmission, helping the engine run stably, ensuring proper lubrication and extending the service life of internal components.

Product LF0111310 is a genuine Mazda part used by Ford on the Duratec 2.3L engine fitted to the Ford Escape. It is manufactured to high quality standards with oil-resistant, heat-resistant rubber combined with a spring-loaded seal lip that offers strong elasticity, helping it stay in close contact with the crankshaft surface and maintain sealing performance under high temperature and high-speed conditions. The product is designed to exact specifications and fits the Ford Escape 2005-2013 2.3 engine precisely without modification.

After prolonged use, the rear crankshaft oil seal may harden, wear at the sealing lip or age due to high temperatures and continuous operation. When this happens, engine oil can leak at the junction between the engine and transmission, leaving oil spots under the vehicle or around the transmission housing. If not replaced promptly, engine oil level will drop, affecting lubrication, increasing the risk of wear to internal engine parts and potentially causing oil contamination on the clutch in manual transmission vehicles.

Product LF0111310 is manufactured to genuine standards, ensuring excellent sealing, outstanding durability and full compatibility for the Ford Escape 2005-2013 2.3 engine.
