7100 852 026 Crankcase for Mercedes-Benz Citaro

What does a compressor crankcase do?

This compressor crankcase serves as a vital housing within the air brake compressor, providing the structural integrity required to manage internal pressure and component alignment. It acts as the core housing that supports the reciprocating motion essential for efficient air production in heavy commercial vehicle pneumatic systems.

Compatible vehicles and engines

This part is specifically compatible with Mercedes-Benz Citaro (O 530) models, including variants like the Citaro G, LÜ, N, GN3, and MUE, as well as Setra Series 400 and Mercedes-Benz Capacity vehicles. It is designed to work seamlessly with OM 457 HLA, OM 457 LA, and OM 447 HLA engines to maintain optimal braking performance.

Installation and maintenance

When performing maintenance or overhaul on the air brake compressor, technicians should inspect the crankcase for any signs of structural fatigue or surface wear. Ensuring a clean mating surface is critical during installation to prevent air leaks or oil contamination within the pneumatic circuit. This component is compatible with WABCO systems.

Troubleshooting and selection

Proper selection of a replacement crankcase helps prevent common issues such as excessive vibration or pressure loss in the braking system. Always verify engine compatibility to ensure correct fitment during the repair process.
