22016995 S3 Volvo FM Compressor Crankshaft

What does a compressor crankshaft do?

The compressor crankshaft acts as the central component in the air brake compressor, converting the engine's rotary motion into the linear movement required for the piston. This component is essential for maintaining consistent compression pressure within the pneumatic braking system of heavy commercial vehicles.

Compatible Volvo FM models

This specific crankshaft is designed for use in Volvo FM models, including the FM 300, FM 340, FM 360, FM 370, FM 380, FM 390, FM 400, FM 410, FM 420, FM 430, FM 440, FM 450, and FM 460, as well as the FM 480 and FM 500 variants. It provides a reliable solution for restoring compressor performance without requiring a complete unit replacement.

Installation and maintenance guidance

During maintenance or when addressing noise and vibration issues in the air system, technicians should inspect the crankshaft and its connected bearings. Ensuring proper alignment during installation is critical to preventing premature wear of the connecting rod bearings and seals. Consult your authorized distributor for fitment verification.

Troubleshooting and system health

Regularly monitoring the compressor's operation can help identify early signs of crankshaft fatigue or bearing wear. Replacing this component during a standard overhaul can significantly extend the service life of the entire air brake compressor assembly.
