20774299 Compressor Cylinder Head compatible with Volvo FMX

What does a compressor cylinder head do?

This cylinder head is a vital component of the air brake compressor assembly, responsible for sealing the combustion or compression chamber to maintain consistent pressure. It is manufactured using high-strength components to withstand the rigorous thermal and mechanical stresses encountered during continuous operation in heavy commercial vehicle applications.

Vehicle and engine compatibility

This part is specifically compatible with Volvo FMX models featuring the D11B engine, including variants such as 330, 370, 380, 400, 410, 420, 430, 440, 450, 460, and 500. It also serves various Volvo FM models including FM 300 through FM 500 series. Proper fitment ensures the compressor maintains optimal volumetric efficiency within the pneumatic system.

Installation and maintenance

Technicians should inspect the cylinder head for signs of thermal fatigue or surface irregularities during routine maintenance. When replacing this component, ensure that all mounting surfaces are clean and that the head is tightened to the specific torque requirements to prevent air leaks or pressure loss in the braking system.

Selection guidance

Consult your authorized distributor to ensure this component matches your specific compressor architecture and engine configuration.
