20845313 SP1 Twin Cylinder Compressor for Volvo FM13

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, providing the necessary compressed air for reliable operation. Designed for high-demand environments, this unit features a water-cooled mechanism to manage thermal loads during continuous operation, ensuring consistent pressure delivery for the braking and suspension systems.

Vehicle and engine compatibility

This specific unit is engineered for compatibility with Volvo FM13 trucks equipped with D13B engines. It features a 704cm³ swept volume, a cylinder bore of Ø85.00 mm, and a stroke of 62 mm. The design includes an integrated ESS feature and a water-cooled valve plate to maintain optimal performance under heavy-duty service conditions.

Installation and maintenance guidance

When performing installation or maintenance, technicians should verify that the water inlet and outlet ports (M16x1,5) and the air outlet port (M26x1,5) align with the existing vehicle configuration. It is essential to check the through drive mechanism and mounting flange to ensure perfect alignment with the engine drive gear.

System reliability and selection

Maintaining regular checks on the air unloader port and cooling lines prevents system pressure fluctuations. For professional workshop technicians and fleet managers, ensuring exact matchment with original specifications is critical for long-term system reliability.
