21751630 Volvo B8R D8K Compressor

What does a single cylinder compressor do?

This single cylinder compressor serves as a vital component within the pneumatic braking system, providing the necessary air pressure for heavy commercial vehicle operation. Engineered with high-strength components, it ensures consistent performance even under the demanding thermal loads typical of long-haul transport. The water-cooled design allows it to integrate seamlessly into the engine cooling circuit to prevent overheating during sustained use.

Vehicle and engine compatibility

This unit is specifically compatible with Volvo B8R trucks equipped with D8K engines. The design includes a through drive configuration and an ESS feature to optimize system reliability. It is built to meet the rigorous requirements of heavy commercial vehicle service environments.

Installation and maintenance guidance

For correct installation, technicians should verify the water inlet and outlet port connections (M16x1.5) and ensure the air unloader port (M10x1) is correctly routed. Given the water-cooled valve plate construction, maintaining the integrity of the engine cooling loop is essential for optimal compressor longevity and performance.

Selection and performance

When selecting replacement parts, always match the technical specifications such as the 360cm³ swept volume and port sizes to ensure perfect fitment. Consult your authorized distributor for further assistance.
