20382347 S3 Compressor Crankshaft Flange — Volvo NH12

What does a crankshaft flange do?

This compressor crankshaft flange plays a critical role in the air brake compressor assembly by facilitating the transfer of rotational motion within the pneumatic system. Constructed from high-strength components, it is designed to withstand the continuous mechanical stress found in heavy commercial vehicle applications.

Vehicle and engine compatibility

This component is specifically fitted to Volvo NH12 trucks, including various power outputs such as the NH 12/460, NH 12/340, NH 12/380, and NH 12/420 models. It serves as a precise replacement for original equipment parts to maintain optimal air pressure delivery.

Installation and maintenance guidance

When performing maintenance or repair, technicians should verify the pilot diameter, bolt hole circle, and seal seat size to ensure perfect alignment. Proper installation prevents premature vibration or air leakage within the compressor housing.

Selection and troubleshooting

Selecting the correct flange based on the compressor type is essential for long-term reliability in heavy-duty service environments.
