4089222 CUMMINS ISB6.7 Crankshaft Flange

This crankshaft flange serves as a vital mechanical link within the air brake compressor assembly, ensuring stable power transmission from the engine to the compressor system. Engineered with heavy-duty grade materials, it maintains structural integrity under high-stress operating conditions to prevent mechanical slippage or vibration issues.

4089222 is the OE-equivalent CUMMINS crankshaft flange used in the CUMMINS ISB6.7 engine system. This precision-engineered part ensures seamless compatibility and maintains the operational standards required for heavy commercial vehicle engine-driven compressor systems.

Workshop technicians should verify the alignment of the crankshaft flange during the installation of air brake compressor repair kits. Proper seating and torque application are essential to ensure long-term reliability and to prevent damage to the compressor drive mechanism. Regular inspections of the drive coupling area are recommended during routine heavy commercial vehicle maintenance cycles.
