25 18 13 Crankshaft Flange for Knorr-Bremse Systems

The crankshaft flange serves a critical role within the air brake compressor system, ensuring stable power transmission and structural alignment during high-pressure operations. Designed for heavy-duty grade materials, this component provides the necessary durability to withstand the constant mechanical stress found in heavy commercial vehicle engine environments.

25 18 13 is the OE-equivalent crankshaft flange used in the BMC and Cummins ISBE4 and ISBE4.5 engine systems. This part is engineered to meet the rigorous standards of modern air brake compressor repair kits, ensuring seamless integration with compatible Knorr-Bremse hardware and other heavy-duty braking components.

For workshop technicians, this part offers precise fitment to prevent leakage or mechanical misalignment during compressor assembly. Maintaining the integrity of the crankshaft flange is vital for the long-term service life of the air compressor system. Regular inspection of the compressor components during scheduled maintenance intervals helps prevent unexpected downtime in heavy commercial vehicles.
