Corteco 20031171B Crankshaft Seal

Description

The Corteco 20031171B is a crankshaft seal designed to prevent oil leaks from the engine’s crankshaft. This seal is crucial for maintaining proper lubrication and preventing engine damage. It’s commonly used in engine repair and maintenance. This seal provides a reliable barrier against oil loss, contributing to extended engine life and optimal performance. It measures 15 x 92 x 92 mm and is manufactured in Turkey.

Key Features & Benefits

This little seal’s job is to keep oil in and keep contaminants out. Specifically, it seals the space between the crankshaft – that’s the main rotating part of your engine – and the engine block. It prevents oil from leaking where the crankshaft comes out of the engine, and also stops dirt, dust, and debris from getting inside where it shouldn't be. It’s really just a simple rubber or polymer ring, but it’s doing a pretty crucial job. Think of it as a barrier right where the crankshaft exits the engine. The crankshaft spins constantly, and that seal has to move with it, maintaining a tight fit against the crankshaft journal. That’s how it keeps oil contained within the engine. It's located down in the front or rear of the engine, usually behind the harmonic balancer or flywheel. You wouldn’t normally see it unless you were actively working on the engine.

Symptoms, Risks & Replacements

If this seal fails, you'll start to see oil leaks. At first, it might just be a small drip, but it can quickly get worse. A leaking seal can cause a lot of problems – you'll lose oil, which obviously isn’t good, and the oil getting onto other components like the belts or clutch disc can cause them to wear out prematurely. You’ll notice if you start smelling burning oil, or if you see oil accumulating under the front or rear of your engine. Ignoring it can lead to bigger issues down the road, so it’s best to address it when you first see a leak. Parts like these are fairly inexpensive, and you can find a good crankshaft seal on sites like Fixparts Online, making it a simple repair when caught early.
