8500006 SP1 Volvo FL12 TD122 Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is a vital component within the air brake system of heavy commercial vehicles, responsible for generating the pressurized air required for braking and pneumatic functions. Built with high-strength components, this unit is specifically designed to withstand the rigorous thermal and mechanical stresses encountered during continuous operation in heavy-duty environments.

Compatibility and engine fitment

This specific model is engineered for Volvo FL12 trucks equipped with TD122 engines. The unit features a water-cooled design to maintain thermal stability during long-haul operations and high demand cycles. It is equipped with an ESS feature and a water-cooled valve plate to ensure consistent performance under heavy load.

Technical specifications and installation

For professional installation, technicians should note the technical specifications: the unit features an Ø88.00 mm cylinder bore, a 50 mm stroke, and an air outlet port size of M26x1,5. The water inlet and outlet ports are M16x1,5. Ensure that all port connections and the gear drive interface match the existing engine configuration to guarantee seamless integration.

Selection and replacement guidance

When replacing this unit, it is essential to verify that the mounting flange, drive gear, and cooling connections are identical to the removed component. This ensures optimal pressure delivery and prevents system leaks or mechanical misalignment in the engine's air supply circuit.
