85000614 SP1 Volvo B9R D9B Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a vital component within the pneumatic braking system of heavy commercial vehicles, ensuring consistent air pressure for braking operations. Built with high-strength components, this unit is engineered to withstand the rigorous thermal and mechanical demands of sustained heavy-duty operation.

Compatible vehicles and engines

This specific model is designed for use in Volvo B9R trucks equipped with D9B engines. It features a water-cooled design to maintain thermal stability during long hauls and includes an ESS feature to optimize system performance. The unit utilizes a gear drive mechanism to ensure high torque transmission without the risk of slip.

Installation and maintenance

When performing installation, technicians should verify that the water inlet and outlet ports (M16x1.5) and the air outlet port (M26x1.5) align with the existing vehicle lines. Given the water-cooled valve plate and through-drive configuration, ensuring proper coolant flow and mounting alignment is critical for preventing overheating or premature wear.

Technical verification

To ensure correct fitment, always compare the technical specifications of the removed unit with this component, specifically checking the cylinder bore of 85.00 mm and the swept volume of 704cm³.
