1784109 SCANIA R440 Twin Cylinder, Air Compressor

This twin cylinder air compressor is a critical component for maintaining stable pneumatic pressure within the heavy commercial vehicle air brake system. Designed with high-strength components, it ensures reliable air production and consistent performance under high-load conditions. The unit features a water-cooled design to manage thermal loads effectively during continuous operation.

1784109 is the OE-equivalent of the SCANIA 1784109 twin cylinder air compressor used in the SCANIA R440. This precision-engineered part meets strict technical requirements for fitment and functionality. It is specifically engineered to provide optimal service for the SCANIA R440 model, ensuring the pneumatic system operates within specified parameters.

The assembly includes a dual-cylinder configuration with a Ø88.00 bore and a 50 mm stroke, providing a swept volume of 608cm³. Technical specifications include an M26x1,5 air inlet port, an M22x1,5 air outlet port, and an M22x1,5 unloader port. The water-cooled system utilizes M18x1,5 inlet and outlet ports to maintain stable operating temperatures during service.

Workshop technicians should ensure all port connections are secured to prevent pressure leaks. Regular maintenance of the cooling lines and checking the unloader port functionality is recommended to prevent system degradation. This part is designed for seamless integration into existing heavy-duty pneumatic circuits.
