3090385 Crankshaft Flange for Volvo NH12 D12A

What does a compressor crankshaft flange do?

This compressor crankshaft flange is a vital component within the air brake compressor assembly, responsible for securing the drive mechanism to the crankshaft. Manufactured with high-strength components, it ensures reliable power transmission and maintains the structural integrity of the compressor during high-pressure cycles.

Compatible vehicles and engines

This specific flange is compatible with Volvo NH12 trucks equipped with D12A engines. It is engineered to meet the rigorous demands of heavy commercial vehicle service, providing a precise fitment that minimizes vibration and prevents air leakage within the pneumatic system.

Installation and maintenance

For successful installation, technicians should verify that the pilot diameter, bolt hole circle, and seal seat size match the existing compressor housing. Proper alignment during assembly is essential to prevent premature wear or mechanical vibration during operation.

Troubleshooting guidance

Regular inspection of the flange and drive connection can help prevent unexpected downtime. If vibration or air leaks are detected in the compressor system, checking the integrity of the crankshaft flange is a recommended maintenance step.
