85000487 SP1 Volvo B9R D9B Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles, providing the necessary air pressure for reliable braking performance. Engineered with high-strength components, this unit is specifically designed to maintain thermal stability during sustained high-demand operations through its integrated water-cooling system.

Vehicle and engine compatibility

This specific model is compatible with Volvo B9R trucks equipped with D9B engines. The unit features an Ø85.00 mm cylinder bore and a 62 mm stroke, providing a swept volume of 704cm³. It is designed for water-cooled applications with an M26x1,5 air outlet port and an M16x1,5 unloader port.

Installation and maintenance guidance

For workshop technicians, it is essential to verify the mounting flange and drive type before installation. This unit features a through-drive configuration and includes an ESS feature for optimized system performance. Ensure all water inlet and outlet ports (M16x1,5) are properly sealed to prevent coolant leaks during operation.

Selection and verification

When replacing the unit, always cross-reference the removed component's technical specifications to ensure correct fitment regarding the air inlet port (Ø35) and cooling requirements.
