Mercedes-Benz Crankshafts And Parts

All About Crankshafts for Mercedes-Benz

If it weren't for the crankshaft in your Mercedes-Benz, its engine wouldn't run right. That's because the crankshaft's essential to the process of converting the engine's reciprocating motion into rotational motion.

To wit, what a crankshaft is, is a hardened steel or cast iron shaft that rotates and run the length of your engine. It features crankpins that are driven by rods that connect to the engine's pistons, so that the crankpins rotate within the larger end of the connecting rods. (Note that today's Mercedes-Benz vehicles feature an electric starter that works with the crankshaft to turn your engine over.) It also coordinates with the camshaft to synchronize the movement of the pistons and valves.

Signs of Issues with a Crankshaft

Even the highest-quality crankshaft can eventually start to fail, especially if you're not properly lubricating and maintaining it. Symptoms of one in trouble include:

• Knocking sounds from your engine
• Occasional engine stalls
• Reduced oil pressure
• Problems starting your vehicle
• Poorer fuel economy
• Uneven engine idling
• The engine seizing up
• The "Check Engine" dash light coming on

See any, and you'll need to run an inspection, replacing the crankshaft results say to do so. (If you're not sure how to do that, a Mercedes-Benz service center can help.)
