What does a cylinder head do?

This cylinder head is a vital component within the air brake compressor system, responsible for sealing the combustion chamber and managing the air flow required for pneumatic braking. Built from high-strength components, it maintains structural integrity under the high-pressure cycles typical of heavy commercial vehicle operation.

Compatible vehicles and engines

This specific part is designed to fit Volvo NH12 trucks, including variants such as the NH 12/420, NH 12/380, NH 12/340, and NH 12/460 models featuring the D12C engine. It serves as a direct replacement for components used in these specific engine configurations.

Installation and maintenance

When performing maintenance or repairs on the air compressor, technicians should inspect the cylinder head for signs of wear or cracking. Ensuring a proper seal between the head and the compressor block is essential to prevent pressure loss in the pneumatic system.
