20382347 S3 Crankshaft Flange for Volvo FH16 D16C

What does a crankshaft flange do?

The compressor crankshaft flange serves as the vital 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 essential centering, sealing, and load transfer duties between the housing and the crankshaft. This component ensures that the drive—whether gear, belt-pulley, or coupling—is perfectly aligned to prevent premature wear.

Compatible vehicles and engines

This specific part is engineered for Volvo FH16 vehicles equipped with D16C engines. It maintains high-performance standards for heavy commercial vehicle applications, providing a reliable connection within the pneumatic braking system. The component is designed to withstand the high-pressure environments typical of heavy-duty engine drives.

Installation and maintenance

For proper installation, technicians should verify that the pilot diameter and bolt hole circle match the existing assembly. Mismatched dimensions can lead to rapid leakage or excessive vibration even if the part appears to fit. Regular inspection of the seal seat and bearing seat is recommended during routine maintenance to prevent air leaks.

Selection and troubleshooting

Maintaining a stable connection within the compressor assembly is crucial for consistent braking performance. Always consult your authorized distributor to ensure precise fitment for your specific engine configuration.
