Purpose and function in the BMW M engine

The offered eccentric shaft is a component from the Camshafts group, responsible for controlling the valve mechanism in engines installed in the BMW F10 M5 and F12/F13 M6. Its profile and cam arrangement are adapted to high-performance M series power units, where precise timing phase reproduction at high rotational speeds is crucial.

A properly selected eccentric shaft ensures:

• stable valve opening and closing in cylinders 1–4,
• proper cooperation with the timing control system,
• maintenance of the power unit's factory operating parameters.

Benefits of using an original BMW component

Choosing an original eccentric shaft from the BMW OE group means maintaining compliance with the vehicle's factory technical documentation. Reproduction of cam shape, axiality, and manufacturing tolerances is crucial for the proper operation of the entire timing system, especially in engines with high specific power.

The main advantages of using this component include:

• secure fit to the cylinder head and other timing components,
• reduction of the risk of improper valve operation and associated engine control unit errors,
• maintenance of the power unit's operating characteristics in accordance with the manufacturer's assumptions.

Condition and service application

The item comes from the used parts group, which allows for economical repair of the timing system while maintaining the original BMW specification. This type of component is particularly useful for:

• repairs after a mechanical timing failure,
• cylinder head service and replacement of valve control elements,
• restoring the factory engine configuration in vehicles used on tracks or driven dynamically.

Using an original eccentric shaft in place of a worn or damaged element allows for restoring the proper cooperation of all timing sub-assemblies without the need for structural modifications.

Matching by numbers and technical support

The product has a dedicated OEM part number and associated interchangeable numbers, which facilitates verification of compatibility with a specific engine version and vehicle year. Before purchasing, it is worth comparing the markings with service documentation or the existing element to ensure full installation compatibility.
