20774294 VOLVO Twin Cylinder, Air Compressor

The high-strength components of this air compressor ensure reliable pneumatic pressure delivery within the vehicle's air brake system. Designed for heavy commercial vehicle applications, this twin cylinder unit provides consistent performance under demanding operating conditions.

The 20774294 is the OE equivalent of the VOLVO 20774294 air compressor used in the VOLVO TAD1341-1345VE D13 engine. This component is engineered for high-duty cycles and precise air management. The product is fully compatible with the specified engine architecture to maintain system integrity.

Technical specifications include a cylinder bore of Ø85.00 and a 56 mm stroke, with a total swept volume of 636cm³. It features an air outlet port of M26x1,5 and is water-cooled (W) to manage thermal loads effectively. The integration of the ESS feature and water-cooled valve plate ensures optimal durability for workshop technicians during routine maintenance.

Technicians should monitor the water inlet and outlet ports (M16x1,5) and the air unloader port (M16x1,5) during installation to ensure a secure connection. Regular inspection of the through drive and port integrity is recommended to prevent system pressure drops in heavy-duty transport operations.
