20569224 S3 Crankshaft Flange for Volvo FH16 D16C

What does a crankshaft flange do?

The compressor crankshaft flange acts as the vital connecting element between the air brake compressor crankshaft and the engine drive. By carrying the bearing and seal seat on the drive side of the crankshaft, it performs the essential duties of centering, sealing, and load transfer between the housing and the crankshaft. This component ensures that the drive mechanism reaches the crankshaft in a perfectly centered position.

Vehicle and engine compatibility

This specific component is compatible with Volvo FH16 trucks equipped with D16C engines. It is engineered to withstand the high-pressure environments found in heavy commercial vehicle air systems, maintaining structural integrity during continuous operation.

Installation and maintenance guidance

When performing maintenance, technicians should verify that the pilot diameter, bolt hole circle, and seal seat size match the original specifications. Selecting a part with mismatched dimensions can lead to rapid leakage or excessive vibration even if the part appears to fit initially. Always consult your authorized distributor to ensure exact fitment.

Troubleshooting and selection

Proper inspection of the flange during compressor overhauls helps prevent systemic air pressure loss. Maintaining the integrity of this component is crucial for the reliable operation of the entire pneumatic braking system.
