3097150 Volvo FH16 D16A Compressor Crankshaft Flange

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, facilitating the centering, sealing, and load transfer between the housing and the crankshaft. This component is vital for maintaining stable pneumatic pressure in heavy commercial vehicle applications.

Compatible vehicles and engines

This specific flange is engineered for Volvo FH16 trucks utilizing D16A engines. It is designed to meet the rigorous demands of heavy-duty service, ensuring that the drive—whether via gear, pulley, or coupling—reaches the crankshaft in a perfectly centered position to prevent premature wear.

Installation and maintenance

When performing maintenance or repairs, technicians should verify that the pilot diameter, bolt hole circle, and seal seat dimensions match the existing unit. Incorrect dimensions can lead to air leakage or excessive vibration. Always consult your authorized distributor to ensure correct fitment for your specific compressor type.

Troubleshooting and selection

Proper installation of this flange helps maintain the integrity of the air brake system by preventing misalignment during high-pressure cycles.
