4089222 Cummins ISL Crankshaft Flange

The crankshaft flange plays a vital role in the air brake compressor system, facilitating the transfer of rotational energy to the compressor. Engineered with heavy-duty grade materials, this component is designed to withstand high mechanical stress and ensure long-term operational stability in heavy commercial vehicle environments.

4089222 is the OE-equivalent of the CUMMINS 4089222 crankshaft flange used in the CUMMINS ISLE and ISL engine systems. This specific part ensures seamless integration and maintains the required torque transmission efficiency within the compressor assembly. Precision engineering allows it to function reliably under intense industrial workloads.

For workshop technicians, this component is essential during air brake compressor overhauls or rebuilds. It is recommended to inspect the flange surfaces and mounting points during every service interval to prevent system irregularities. Proper installation ensures that the connection between the engine crankshaft and the compressor remains stable during high-load operations.

Maintaining consistent pressure in the pneumatic system requires components that meet exact technical specifications. Using high-strength components like this flange helps prevent leaks and mechanical failures in the air brake system, ensuring that the vehicle remains compliant with safety standards.
