26 14 12 Crankshaft Flange for Air Brake Compressors

What does a crankshaft flange do?

The crankshaft flange plays a vital role in the air brake compressor assembly by ensuring the secure transfer of mechanical motion within the pneumatic system. This high-strength component is engineered to withstand the continuous pressure and rotational stresses experienced during heavy-duty operation in commercial vehicles.

Vehicle and engine compatibility

This part is compatible with various heavy commercial vehicle models including Peterbilt 388, 387, 389, Kenworth T600, T660, W900, and T800. It is specifically designed for applications utilizing Caterpillar C15, C16, and 3176 engines. Additionally, it serves Western Star 4900 and 6900 models, as well as Freightliner Columbia, Cascadia, and Century Class trucks. It is also fitted to Mack Titan and International 9400I, 9900I, and Paystar vehicles.

Installation and maintenance guidance

When performing compressor maintenance, technicians should inspect the flange for signs of uneven wear or surface degradation. Proper installation ensures correct axial alignment between the crankshaft and the pulley assembly. It is recommended to verify all mounting tolerances against the manufacturer's service specifications during installation to prevent premature seal failure or air leaks.

System performance and selection

Maintaining the integrity of the crankshaft assembly is essential for consistent air pressure delivery. Using high-strength components helps prevent unplanned downtime in fleet operations. Check the compatibility list for your specific engine configuration.
