20774383 Twin Cylinder Compressor for Volvo FM11

This twin cylinder compressor serves as a critical component within the pneumatic braking system, ensuring consistent air pressure for the vehicle's braking and suspension functions. Built with high-strength components, it is engineered to withstand the high-pressure demands of heavy commercial vehicle operations while maintaining thermal stability through its integrated water-cooling system.

The unit is specifically compatible with Volvo FM11 trucks equipped with D11A engines. This water-cooled assembly features a Ø85.00 mm cylinder bore and a 56 mm stroke, providing a swept volume of 636cm³. It includes an air unloader port (M16x1,5) and specialized water inlet/outlet ports (M16x1,5) to manage heat during continuous operation.

For workshop technicians performing replacement, it is essential to verify that the through-drive configuration and port locations match the existing installation. When installing this component, ensure all water and air connections are secured to prevent leaks in the pneumatic circuit. Proper mounting is vital to minimize vibration and extend the service life of the internal valve plate.

Consult your authorized distributor to ensure correct fitment for your specific engine configuration.
