571287 SCANIA T420 Twin Cylinder, Air Compressor

This high-strength component serves as a critical part of the pneumatic braking system, ensuring consistent air pressure delivery for heavy commercial vehicles. As a twin cylinder air compressor, it is engineered to withstand rigorous operating conditions while maintaining precision in air displacement and thermal regulation through its integrated water-cooling-system features.

571287 is the OE-equivalent of the SCANIA 571287 air compressor used in the SCANIA T420 model. This component is specifically designed to match the original technical requirements for seamless integration into the vehicle's pneumatic circuit. The part features a dual-cylinder configuration with a 608cm³ swept volume and precision-engineered ports including an M26x1,5 inlet and M22x1,5 outlet to ensure a perfect fit.

Workshop technicians should note that this unit is a water-cooled (W) model, requiring proper connection of the M18x1,5 water inlet and outlet ports to prevent overheating. The installation process requires attention to the through-drive mechanism and the ESS feature compatibility. Regular inspections of the air unloader port (M22x1,5) and the cooling lines are recommended to ensure long-term reliability within the heavy commercial vehicle service interval.

By choosing this high-strength component, service professionals can ensure that the vehicle's air brake systems remain fully operational even under extreme load conditions. The precision of the Ø88.00 mm cylinder bore ensures consistent volumetric efficiency for the T420 series.
