25 17 13 Crankshaft Flange for Air Brake Compressors

What does a compressor crankshaft flange do?

A compressor crankshaft flange is a critical component within the air brake compressor assembly that facilitates the transfer of motion required for pneumatic compression. This high-strength component is engineered to withstand the constant mechanical stresses encountered in heavy-duty air brake systems, ensuring long-term reliability and stable pressure delivery.

Compatible vehicles and engines

This part is widely used in various heavy commercial vehicles, including models from Freightliner, Kenworth, Peterbilt, and Iveco. It is specifically designed to operate with Cummins engines such as the ISB, ISC, and ISF series across various vehicle types like buses and trucks. It is also compatible with Knorr-Bremse systems.

Installation and maintenance

When replacing this component, technicians should ensure that all mounting surfaces are clean and free of debris to prevent air or oil leaks. It is essential to verify that the flange dimensions align perfectly with the existing crankshaft to maintain proper axial clearance and prevent premature wear of the compressor assembly.

Troubleshooting and selection

Monitoring for excessive vibration or unusual noise from the compressor can indicate that the flange or its associated bearings require inspection. Maintaining the integrity of this component is vital for the overall performance of the pneumatic braking system.
