3097150 Crankshaft Flange for Volvo FM12 D12D

What does a crankshaft flange do?

This crankshaft flange serves as a critical component within the air brake compressor assembly, ensuring stable connection and rotation of the internal drive mechanism. It is manufactured using heavy-duty grade materials to withstand the rigorous mechanical stresses found in heavy commercial vehicle pneumatic systems.

Compatible vehicles and engines

Designed specifically for Volvo FM12 trucks with D12D engines, this part ensures precise alignment within the compressor housing. It is also suitable for other heavy commercial vehicles and construction machinery requiring equivalent specifications. Check the compatibility list to confirm fitment.

Installation and maintenance

When replacing the flange, technicians should verify the pilot diameter and bolt hole circle to prevent vibration or air leakage. Proper installation is essential for maintaining the integrity of the compressor's drive system and preventing premature wear of internal seals.

Troubleshooting guidance

If the compressor experiences excessive vibration or air pressure fluctuations, inspecting the crankshaft flange for wear or misalignment is recommended to ensure system reliability.
