442 131 13 42 Mercedes-Benz CONECTO Crankshaft Flange

What does a crankshaft flange do?

This crankshaft flange serves as a critical structural component within the air brake compressor assembly, facilitating the secure connection between the crankshaft and the compressor housing. Manufactured with heavy-duty grade materials, it is designed to withstand the high-stress environment of the engine's air compression cycle while maintaining precise alignment and preventing air or oil leakage.

Compatible Mercedes-Benz models

This specific part is compatible with Mercedes-Benz CONECTO (O 345) models, including variants M, UE, H, and CONECTO C, specifically when paired with OM 447 HLA engines. It is engineered to meet the exact dimensions required for these heavy commercial vehicle configurations to ensure seamless integration into the existing pneumatic system.

Installation and maintenance

For workshop technicians, it is vital to verify that the flange matches the compressor type and engine specifications during installation. Proper mounting is essential to prevent excessive vibration or premature wear of the compressor's internal components. Always ensure that the seating surfaces are clean and free of debris before final assembly.

System reliability

Maintaining the integrity of the crankshaft flange helps prevent system pressure drops and ensures reliable braking performance for the vehicle's air system. Consult your authorized distributor to check the compatibility list.
