20889546 Volvo FM D11B Compressor Cylinder Head

What does a compressor cylinder head do?

This cylinder head is a critical component within the air brake compressor assembly, responsible for sealing the combustion or compression chamber to maintain consistent air pressure. Built from heavy-duty grade materials, it is designed to endure the high-temperature and high-pressure environments typical of heavy commercial vehicle braking systems.

Vehicle and engine compatibility

This component is specifically compatible with Volvo FM series trucks, including models such as the FM 300, FM 340, FM 360, FM 370, FM 380, and up to the FM 500. It is designed for use in Volvo FM11 vehicles powered by the D11B engine.

Installation and maintenance guidance

When replacing the cylinder head, technicians should inspect the surrounding valves and gaskets to ensure a perfect seal. Proper installation prevents air leaks that could compromise the braking performance of the vehicle's pneumatic system.

System performance and selection

Maintaining a clean and properly seated cylinder head is essential for preventing pressure drops in the air brake circuit. Consult your authorized distributor to ensure this part matches your specific compressor architecture.
