7500 100 002 Mercedes-Benz Compressor Crankshaft Flange

The compressor crankshaft flange is a critical component within the air brake compressor assembly, responsible for maintaining the structural integrity and rotational alignment of the crankshaft. This component is manufactured using high-strength components to withstand the continuous mechanical stresses and thermal fluctuations inherent in heavy commercial vehicle braking systems.

This specific part, identified by code 7500 100 002, is the OE equivalent of the Mercedes-Benz 4471300045 compressor crankshaft flange used in Mercedes-Benz Conecto (O 345) with OM 447 HLA engines. It ensures precise motion transfer within the compressor unit, maintaining the necessary pressure for the pneumatic braking system.

To ensure correct installation, technicians should verify the pilot diameter, bolt hole circle, and seal seat size against the existing part. Even if a flange appears compatible, any mismatch in these dimensions can lead to premature vibration or air leakage. When replacing this component, it is recommended to inspect the surrounding crankshaft bearings and seals to ensure complete system reliability.

Proper selection based on the compressor model and OE number is essential for preventing operational failure. For technical guidance on fitment or to confirm compatibility with specific compressor types, consult your authorized distributor.
