7200 851 023 Mercedes-Benz Compressor Crankshaft

What does a compressor crankshaft do?

This compressor crankshaft serves as a critical moving component within the air brake compressor, responsible for transferring rotary motion from the engine to the piston assembly. Built with heavy-duty grade materials, it is engineered to maintain precise tolerances under high-pressure pneumatic conditions, ensuring consistent compression performance for heavy commercial vehicle braking systems.

Compatible vehicles and engines

This component is specifically designed for use in Mercedes-Benz Conecto (O 345) models including the 12M and 18M variants, as well as Mercedes-Benz Citaro (O 530) series such as the Citaro G and N models. It is also compatible with Setra Series 400 MultiClass models and Mercedes-Benz Capacity units, supporting engines like the OM 457 LA and OM 457 HLA. These parts are compatible with WABCO systems.

Installation and maintenance

For optimal performance, technicians should verify that all connecting rod clearances and bearing tolerances meet OEM specifications during installation. Regular inspection of the crankshaft assembly can help prevent common issues such as excessive vibration or pneumatic system pressure drops. Consult your authorized distributor to ensure correct fitment.

Troubleshooting and selection

When replacing internal compressor components, it is essential to inspect the surrounding seals and bearings to prevent premature wear of the new crankshaft.
