4089222 Cummins QSX Crankshaft Flange

This crankshaft flange plays a critical role in the transmission of mechanical energy within the air brake compressor assembly. Engineered to withstand high-stress environments, it ensures a stable connection between the engine and the compressor, maintaining consistent air pressure delivery for heavy commercial vehicle systems. The use of heavy-duty grade materials guarantees long-term reliability during operation.

4089222 is the OE-equivalent of the CUMMINS 4089222 crankshaft flange used in the CUMMINS QSX engine systems. This component is essential for maintaining the efficiency of the air brake compressor, providing a precise fit to prevent mechanical deviations during high-load cycles. It is specifically designed for integration with heavy-duty engine architectures.

Workshop technicians should ensure that the mounting surfaces are clean and free of debris before installation to guarantee optimal alignment. Proper torque specifications must be followed during assembly to prevent vibration or premature wear of the compressor system. Regular inspection of the flange and connection points is recommended during routine service intervals to ensure peak pneumatic performance.
