MAN 51021016086 crankshaft

Description

The crankshaft is a vital rotating component within the engine, converting reciprocating motion of the pistons into rotational motion to power the vehicle. It is used in the engine's crankcase to facilitate this critical process. This MAN crankshaft, with MPN 51021016086, is engineered for high strength and durability, ensuring reliable performance and extended engine life. Its precision manufacturing minimizes vibration and maximizes power transfer efficiency. Manufactured in Germany, it measures 175 x 180 x 580 mm.

Key Features & Benefits

This part basically takes the up and down motion of your pistons—from when the engine burns fuel—and turns it into the rotational power that eventually gets to your wheels. It’s a pretty simple idea, but it needs to be incredibly strong and precisely balanced. It has offset journals—those are like little arms—where the connecting rods from the pistons attach. As the pistons go up and down, those journals go in a circle, and that’s what spins the whole engine. It’s absolutely central to how your car runs. Think of it as the backbone of the engine’s power generation. Everything starts with the crankshaft. It's connected to the flywheel, which smooths things out, and then through the transmission and driveshaft to the wheels. Without a good crankshaft, the engine just won't produce any power. It doesn’t directly control things like steering or brakes, but everything that does work—like the power steering pump and alternator—relies on the engine turning, which relies on the crankshaft.

Symptoms, Risks & Replacements

It’s a big deal. Because it's under such constant stress—those pistons are hitting it thousands of times a minute—it has to be incredibly durable. A failing crankshaft can cause all sorts of problems, from rough running and loss of power to really serious engine damage. You’ll notice if something is off; usually it’ll start with vibrations or a knocking sound. It’s made from very strong steel, and it's internally balanced to minimize vibration. It basically acts like a shield protecting the rest of the engine from that forceful piston movement. If it cracks or bends, you're looking at a major repair. We carry a good range of these at Fixparts Online, and getting a quality replacement is really important. It’s not something you want to skimp on.
