Purpose and technical specifications

The presented crankshaft is a structural component designed for N47 Diesel engines used in popular BMW 1, 3, and 5 series models. As a part from the Crankshafts group, it is responsible for converting the reciprocating motion of the pistons into rotational motion, which has a direct impact on the smoothness of the engine's operation, vibration levels, and the durability of the entire crank-piston system.

By maintaining factory geometry and properly selected mass, the N47 crankshaft ensures proper engine balancing, which is particularly important in modern diesel units operating under high loads and high torque.

Benefits of using an original BMW crankshaft

Using an original BMW crankshaft in an N47 engine allows you to maintain the unit's operating parameters at the level intended by the manufacturer. In practice, this means:

• stable engine operation across the entire rev range,
• proper compatibility with stock bearings and connecting rods,
• appropriate load distribution within the crank-piston system,
• preservation of factory fitting tolerances and journal alignment.

For the user, this translates into predictable engine behavior, a lower risk of secondary damage, and the possibility of professional diesel engine regeneration without compromising on quality.

Component condition and use in service practice

The offered crankshaft is a used component, which in workshop practice is often a cost-effective solution while maintaining high functionality. This type of part is particularly useful for:

• major overhauls of the N47 engine following damage to the crank-piston system,
• professional engine regeneration in fleet vehicles,
• optimizing repair costs while maintaining the original BMW specification.

Choosing a used OEM crankshaft allows for matching the existing engine configuration without the need to modify accessories or ECU software.

Part selection and compatibility with reference numbers

The N47 crankshaft has a dedicated OEM part number and associated interchangeable numbers, which facilitates precise identification in BMW catalogs and service systems. Before purchasing, it is worth comparing the markings with the vehicle documentation or engine number to ensure full compatibility with the specific version of the diesel unit.

This approach minimizes the risk of mismatch and allows for efficient installation in workshop conditions, without the need for additional modifications or mechanical adjustments.
