20866605 VOLVO Twin Cylinder, Air Compressor

The high-strength components of this twin cylinder air compressor ensure reliable pneumatic pressure delivery within the braking system. Designed for heavy commercial vehicle applications, this unit maintains consistent performance under demanding operational conditions through its advanced water-cooled architecture.

The 20866605 product is the OE equivalent of the VOLVO 20866605 twin cylinder, air compressor used in VOLVO vehicles. This high-strength component is engineered to meet strict technical requirements for heavy-duty duty cycles and system reliability.

This unit features a cylinder bore of Ø85.00 mm and a stroke of 62 mm, providing a swept volume of 704cm³. The assembly includes a water-cooled valve plate and is optimized for integration with specific air brake systems to ensure seamless pneumatic-to-mechanical energy conversion.

Maintenance technicians should regularly check the water inlet and outlet ports (M16x1,5) and the air unloader port (M12x1,5) to prevent system leaks or pressure drops. Ensure the through-drive alignment is correct during installation to maintain long-term operational stability.
