The Corteco 12013458B is a crankshaft shaft seal designed to prevent oil leaks from the engine’s crankshaft. This seal is a critical component in maintaining engine lubrication and preventing damage. It's commonly used in a variety of engine applications where the crankshaft exits the engine block. This seal enhances engine reliability by effectively containing oil within the engine, reducing the risk of oil starvation and subsequent engine wear. It measures 12 x 54 x 54 mm and is manufactured in Italy. This seal basically prevents oil from leaking out where the crankshaft comes out of the engine block. The crankshaft is what converts the up – and – down motion of the pistons into the rotational power that drives your wheels, and it spins within a hole in the engine. This seal sits right there, around the shaft, keeping the oil in and dirt out. It’s a pretty simple part, really, but it does a vital job. Think of it as a barrier. The crankshaft is a major moving part, and there needs to be lubrication around it – that’s the engine oil. This seal keeps that oil contained within the engine where it needs to be, protecting all the internal parts. Without it, oil would sling around, causing a mess and eventually leading to serious damage. It acts like a shield, keeping everything working smoothly. Well, oil leaks are never good. Even a small leak can cause a low oil level, which can quickly ruin your engine. Plus, oil leaking onto belts and other components can cause them to wear out prematurely. You’ll notice if one of these seals fails, usually by seeing oil collecting somewhere near the front or rear of the engine, or smelling burning oil. It’s a relatively inexpensive part to replace, and catching it early can save you a lot of money and headache down the road. You can find a replacement pretty easily – we stock a good range here, and places like Fixparts Online are also good for sourcing these. Ignoring it just means more oil loss and potentially a major engine repair later on. Dedicated support: Crankshaft Shaft Seal (MPN 12013458B) includes a 12-month warranty!
