20701801 S3 Volvo NH12 Compressor Crankshaft Flange

What does a crankshaft flange do?

This crankshaft flange serves as a critical component within the air brake compressor assembly, facilitating the necessary connection and structural stability for the crankshaft. Built with high-strength components, it is engineered to withstand the constant mechanical stresses encountered during heavy-duty operation within the pneumatic braking system.

Compatible Volvo NH12 models

The component is compatible with Volvo NH12 models, including variants such as the NH 12/460, NH 12/340, NH 12/380, and NH 12/420. These parts are essential for maintaining the correct alignment and sealing within the compressor housing of these heavy commercial vehicle engines.

Installation and maintenance guidance

When performing maintenance or repairs on the air brake compressor, technicians should verify the pilot diameter, bolt hole circle, and seal seat size against existing specifications. Ensuring these dimensions match exactly prevents premature leakage or excessive vibration during operation.

Selection and troubleshooting

Selecting the correct flange based on the compressor type and technical dimensions is vital for long-term service life. Consult your authorized distributor to confirm exact fitment for your specific compressor configuration.
