13 03 70 Volvo Compressor Cylinder Head

What does a compressor cylinder head do?

This compressor cylinder head is a vital component within the pneumatic air brake system, responsible for sealing the combustion or compression chamber to ensure efficient pressure generation. Built with high-strength components, it is designed to withstand the intense thermal and mechanical stresses encountered during continuous operation in heavy commercial vehicles.

Compatible Volvo models and engines

This specific part is compatible with various Volvo models, including the A40G articulated hauler, L150H and L250H loaders, and EC380D / EC480D excavators. It is engineered to work seamlessly with Knorr-Bremse systems and is suitable for engines such as the D11, D13, and D16. Always verify the compressor's own reference number to ensure exact fitment.

Installation and maintenance guidance

When performing maintenance or repairs on the air compressor, technicians should inspect the cylinder head for any signs of uneven wear or surface irregularities. Proper installation involves ensuring all mounting surfaces are clean and that gaskets are correctly seated to prevent air leaks. Maintaining the integrity of this component is essential for reliable braking performance.

Troubleshooting and selection

If air pressure drops or the compressor exhibits unusual noise, it may indicate that the cylinder head or its internal valves require inspection. Selecting a high-quality replacement ensures long-term reliability for Volvo construction and heavy-duty machinery.
