1784109 SCANIA R620 Twin Cylinder, Air Compressor

The 1784109 twin cylinder air compressor is engineered to provide consistent pneumatic pressure for heavy-duty engine systems. This high-strength component is designed to maintain optimal airflow and system pressure, ensuring the reliable operation of the vehicle's braking and suspension systems. Its robust construction is specifically tailored for the rigorous demands of the heavy commercial vehicle sector.

1784109 is the OE-equivalent SCANIA 1784109 twin cylinder air compressor used in the SCANIA R620. This part is built to meet strict technical standards for fitment and performance. The assembly features a cylinder bore of Ø88.00 mm and a stroke of 50 mm, providing a precise swept volume of 608cm³. It is designed for water-cooled applications to manage thermal loads effectively during continuous operation.

Workshop technicians should note that this unit utilizes an M26x1,5 air inlet port and an M22x1,5 air outlet port. The integration of the water-cooled valve plate and the ESS feature ensures stability under high-load conditions. When performing maintenance or replacement, ensure that the water inlet (M18x1,5) and outlet (M18x1,5) connections are properly secured to prevent leakage and maintain system integrity.

Regular inspection of the air unloader port (M22x1,5) and the connection points is recommended to ensure the longevity of the pneumatic system. This component is essential for maintaining the pneumatic pressure required for safe vehicle operation in long-haul transport applications.
