571287 SCANIA 124-420 Twin Cylinder, Air Compressor

The heavy-duty twin cylinder air compressor is a vital component in the pneumatic system of heavy commercial vehicles, ensuring consistent air pressure for braking and suspension stability. This high-strength component is engineered to maintain rigorous operational standards under demanding thermal conditions. Designed with a water-cooled mechanism, it provides stable performance for long-haul transport applications.

571287 is the OE-equivalent of the SCANIA 571287 Twin Cylinder, Air Compressor used in the SCANIA 124-420. This unit features a cylinder bore of Ø88.00 and a stroke of 50 mm, resulting in a swept volume of 608cm³. It is specifically designed to meet the precise requirements of the SCANIA vehicle architecture.

For workshop technicians, this assembly offers a direct fit with specialized port configurations including an M26x1,5 air inlet and M22x1,5 air outlet. The inclusion of the ESS feature and water-cooled valve plate ensures compatibility with modern engine cooling systems. Regular inspection of the water inlet and outlet ports (M18x1,5) is recommended during routine maintenance to ensure optimal heat dissipation and system longevity.

Maintaining the integrity of the air supply is essential for fleet safety. This compressor is built to handle heavy-duty cycles within the braking system, providing reliable pneumatic pressure. Technicians should verify all port connections and ensure the through-drive alignment is correct during installation to prevent system leaks or pressure drops.
