1518349 Compatible Crankshaft Flange — Volvo F12

What does a crankshaft flange do?

The compressor crankshaft flange acts as the essential connecting element that links the air brake compressor's crankshaft to the engine drive. It carries the bearing and seal seat on the drive side of the crankshaft, performing the vital duties of centering, sealing, and load transfer between the compressor housing and the crankshaft. This component is crucial for ensuring that the drive mechanism, whether via gear or coupling, remains perfectly aligned.

Vehicle and engine compatibility

This specific flange is compatible with Volvo F12 trucks utilizing TD122 engines. It is engineered to withstand the rigorous operating conditions found in heavy commercial vehicle systems, providing a reliable interface within the air brake compressor assembly.

Installation and maintenance

For proper installation, technicians should verify that all dimensions, including the pilot diameter and bolt hole circle, match the original component requirements. Even a slight mismatch in seal seat size or flange thickness can lead to premature leakage or excessive vibration during operation. Always check the housing label or casting number to ensure exact fitment before assembly.

Troubleshooting and selection

Regular inspection of the flange and its seating surfaces can help prevent air leaks and maintain optimal compressor performance throughout its service life.
