85104248 Volvo FM Series D12C Compressor Head

What does a compressor cylinder head do?

This cylinder head is a critical component of the air brake compressor assembly, responsible for sealing the combustion or compression chamber to maintain consistent air pressure. Built with heavy-duty grade materials, it ensures structural integrity and resistance to the thermal stresses encountered during continuous operation in heavy commercial vehicles.

Compatible Volvo FM series and engines

This component is engineered for use in Volvo FM series trucks, including models such as the FM 410, FM 360, and FM 480, as well as the FM 500. It is specifically compatible with Volvo FM12 trucks equipped with D12C engines, providing a reliable solution for maintaining the pneumatic system's efficiency.

Installation and maintenance guidance

For optimal performance, technicians should verify the cooling type and flange pattern before installation. When replacing this part, it is recommended to inspect the valve plate and gasket surfaces to ensure a complete seal. Maintaining the integrity of the cylinder head prevents air leaks and maintains stable pressure within the braking system.

System reliability and inspection

Regular inspection of the compressor assembly can prevent unexpected downtime. Ensuring that all mounting bolts are torqued to specification helps prevent uneven pressure distribution across the head surface.
