BMW F82 F83 M4 F87 M2 N55 S55 Engine Crankshaft Hub 7574827

BMW F82 F83 M4 F87 M2 N55 S55 Engine Crankshaft Hub is an original part from the Crankshafts category, designed for BMW M-series power units with N55 and S55 engines. This is a precision-engineered component responsible for the stable transfer of torque from the crankshaft to other drivetrain sub-assemblies, which is crucial for engine performance and durability.

Specifications and technical data

• SKU: 7574827
• Mark: BMW (Genuine OE)
• Condition: Used
• OEM Part Number: 7574827
• Category: Crankshafts

Purpose and technical function

The crankshaft hub in the BMW F87 M2 with N55 and S55 engines operates in direct connection with the crankshaft, timing system, and drive accessories. It is responsible for:

• stable seating of components working with the crankshaft,
• precise transfer of torsional loads within the engine's operating RPM range,
• maintaining the correct geometry of the crank-piston system,
• reducing unwanted vibrations in the front part of the engine.

Thanks to its factory design tailored to the specifics of N55 and S55 units, the hub ensures dimensional compliance and proper coaxiality with other drivetrain components.

Application in BMW sports units

The N55 and S55 engines used in the BMW F87 M2 are high-revving, turbocharged units subject to increased mechanical loads. In such an environment, the crankshaft hub operates under conditions of high torsional forces and variable dynamic loads, which is why this original component from the Crankshafts category is particularly valued by users who prioritize drivetrain stability and reliability.

Choosing an original part from dismantling allows for maintaining the factory operating parameters of the crankshaft system, which is important both for cars used daily and for vehicles used occasionally on the track.

Characteristics of the used component

The offered hub comes from dismantling, which means it is an original BMW part previously used in a vehicle. Such components are frequently chosen by conscious users because they:

• retain factory geometry and fitment to the crankshaft,
• allow for reduced repair costs compared to new parts,
• provide an alternative to aftermarket replacements of uncertain quality.

With proper installation and adherence to service procedures, a hub from the secondary market can effectively operate in the drivetrain, ensuring stable torque transfer and proper cooperation with other engine components.

Benefits of using an original crankshaft hub

By choosing this component, you primarily gain:

• factory fitment for N55 and S55 units used in the BMW F87 M2,
• compatibility with the original crankshaft system and engine accessories,
• the ability to maintain the structural integrity of the entire drivetrain,
• a reasonable compromise between repair costs and the quality of the parts used.

For users who consciously service their sports BMWs, using an original hub from dismantling is a way to maintain stable engine operation while keeping the service budget under control.
