1784109 SCANIA P420 Twin Cylinder, Air Compressor

The twin cylinder air compressor is a critical component within the pneumatic braking system of heavy commercial vehicles. It is engineered to provide consistent air pressure through a robust dual-cylinder design, ensuring the reliability of the vehicle's air brake functions. This component utilizes water cooling to maintain optimal operating temperatures during heavy-duty service cycles.

1784109 is the OE-equivalent of the SCANIA 1784109 twin cylinder air compressor used in the SCANIA P420. This high-strength component is specifically designed for seamless integration into the engine systems of heavy commercial vehicles. The precise engineering ensures it meets the strict requirements for high-pressure air generation and distribution within the braking circuit.

For workshop technicians, this unit features a cylinder bore of Ø88.00 mm and a 50 mm stroke, providing a swept volume of 608cm³. The installation involves specific port connections including an M26x1,5 air inlet and M22x1,5 outlet/unloader ports. It is essential to verify the water inlet and outlet (M18x1,5) connections to ensure proper cooling efficiency and prevent overheating during operation.

Maintaining the air compressor involves regular inspections of the water cooling lines and ensuring no debris enters the intake ports. Regular service prevents pressure drops in the pneumatic system, maintaining vehicle safety and performance.
