8112543 Volvo FL12 TD123 Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the pneumatic braking system, providing the necessary air pressure for heavy commercial vehicle operation. Built with high-strength components, it is engineered to maintain consistent performance under demanding thermal loads through its integrated water-cooling system.

Compatibility with Volvo FL12

This specific model is compatible with Volvo FL12 trucks equipped with TD123 engines. It features an M26x1,5 air outlet port and an M22x1,5 unloader port to ensure seamless integration into the existing pneumatic circuit. The unit is designed for through-drive applications to match original engine configurations.

Installation and maintenance

For proper installation, technicians should verify that the water inlet and outlet ports (M16x1,5) align with the engine's cooling lines. Ensure all connections are torqued to specification to prevent pressure drops. Regular inspection of the water-cooled valve plate is recommended to maintain optimal air delivery and prevent system contamination.

Technical selection guidance

When replacing an existing unit, always verify that the technical specifications such as the Ø88.00 bore and 608cm³ swept volume match the requirements of the vehicle's air system.
