8112584 SP1 Volvo FL12 TD123 Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is a vital component in the air brake system of heavy commercial vehicles, designed to generate a consistent supply of compressed air through two piston-cylinder assemblies. By utilizing two compression strokes, this unit delivers higher air output than single-cylinder alternatives, ensuring faster reservoir replenishment for demanding braking needs.

Vehicle compatibility and engine fitment

This specific model is designed for Volvo FL12 trucks equipped with TD123 engines. It features a water-cooled design to maintain thermal stability during intensive operation and includes an integrated ESS feature for enhanced system reliability. The unit is gear-driven with a through drive configuration, ensuring high torque transmission without the risk of belt slip.

Technical installation and maintenance

For proper installation, technicians should verify the water inlet and outlet port compatibility (M16x1,5) and ensure the air outlet port (M26x1,5) matches the existing lines. Given the technical specifications including an Ø88.00 mm bore and 50 mm stroke, it is essential to confirm that all mounting interfaces and port locations align with the current engine setup.

Selection and troubleshooting guidance

To ensure optimal performance, regular inspection of the water cooling circuit and air ports is recommended. Always check the removed unit's identification to ensure exact matching of drive gears and mounting flanges.
