7200 862 011 Mercedes-Benz Compressor Crankshaft

What does a compressor crankshaft do?

The compressor crankshaft serves as the central component within the air brake compressor, responsible for converting the engine's rotary motion into the reciprocating motion required for the compression stroke. This high-strength component is essential for maintaining consistent air pressure within the pneumatic braking system of heavy commercial vehicles.

Compatible Mercedes-Benz vehicles and engines

This specific crankshaft is engineered for compatibility with Mercedes-Benz ACTROS MP4/MP5, ANTOS, and AROC S series, particularly those utilizing the OM 936 engine. It is also suitable for Setra Series 400 and Mercedes-Benz ECONIC 2 models. This part is frequently used in vehicles requiring reliable pneumatic performance under heavy loads.

Installation and maintenance guidance

During installation, technicians should verify the alignment of the connecting rod and ensure all bearings are seated correctly to prevent vibration. Proper lubrication and adherence to service intervals are critical to maintaining the integrity of the crankshaft and the overall compressor assembly.

Troubleshooting and selection

Regular inspection of the crankshaft assembly can help prevent sudden pneumatic system failures. Choosing high-strength components helps maintain optimal compression efficiency in heavy commercial vehicle applications.
