22203109 Volvo FMX II Cylinder Head — Air Brake

What does a compressor cylinder head do?

This compressor cylinder head serves as a critical component within the air brake compressor assembly, managing the compression chamber and ensuring airtight integrity. Manufactured with high-strength components, it is designed to withstand the intense thermal and pressure fluctuations encountered during heavy-duty operation in commercial vehicle braking systems.

Compatible Volvo vehicles and engines

This specific unit is compatible with Volvo FMX II (330, 370, 410, 420, 450, 460, 500, 540) and Volvo FM (300, 330, 340, 360, 370, 380, 390, 400, 410, 420, 430, 440, 450, 460, 480, 500) trucks. It also fits various Volvo FMX configurations. Always verify the compressor architecture before selection.

Installation and maintenance guidance

For workshop technicians performing maintenance, it is vital to inspect the cylinder head surface and valve plate interface during installation. Ensuring the sealing surfaces are clean and free of debris helps prevent air leaks and maintains optimal pneumatic output for the vehicle's braking system.

Troubleshooting and selection

When replacing this component, technicians should check for signs of thermal fatigue or uneven wear on the cylinder walls to ensure long-term reliability under sustained heavy loads.
