Technical characteristics of the camshafts

The presented camshafts are responsible for precise control of valve opening and closing phases in the engine, which directly affects the unit's operating culture, performance, and fuel consumption. Thanks to the factory cam geometry and a properly selected profile, the component ensures:

• stable cylinder filling across the full RPM range,
• proper synchronization of valve operation with the crankshaft,
• maintenance of factory power and torque parameters,
• consistency with the factory engine control unit software.

Original camshafts are particularly important in modern units, where even minor deviations in the cam profile can cause control errors, power loss, or rough idling.

Purpose and application

This set of camshafts is dedicated to power units used in F20, F21 LCI, 116d, and Mini F56 models with the B37 engine, although the component itself comes from the Mercedes range. Such a combination is characteristic of contemporary designs, where manufacturers share technical solutions while maintaining high quality standards.

Choosing an original component from a disassembly allows for maintaining the factory engine operating characteristics without the need for adaptation or modification of other sub-assemblies. This is especially important for vehicles used intensively, where parameter repeatability and reliability in daily use are key.

Benefits of using original camshafts

Using original camshafts from the Mercedes range brings a number of practical service and operational benefits:

• preservation of the factory operating characteristics of the power unit,
• reduction of the risk of adaptation problems in the engine control unit,
• better parameter repeatability compared to low-quality replacements,
• possibility of economical repair thanks to the use of parts from disassembly.

For workshops and private users, this means a more predictable repair result and a lower risk of needing to re-intervene in the timing system. The used OEM component is often a reasonable compromise between cost and durability, especially in the case of advanced engine designs.

Condition, verification, and fitment

The component comes from a disassembly and is intended for re-installation after prior verification by a mechanic for wear on mating surfaces. Before purchasing, it is worth comparing the markings with the vehicle documentation or the manufacturer's catalog to confirm full compatibility with the given engine configuration.

Thanks to the presence of the OEM part number and available interchangeable numbers, the workshop has the ability to precisely match the component to a specific version of the power unit, which minimizes the risk of ordering errors and speeds up the repair process.
