8113264 SP1 Compatible Twin Cylinder Compressor for Volvo

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a vital component within the air brake system of heavy commercial vehicles, generating the compressed air necessary for reliable braking performance. Utilizing two piston-cylinder assemblies, this unit provides higher air output compared to single-cylinder alternatives, ensuring faster reservoir replenishment for demanding operational cycles.

Compatibility with Volvo engines

Designed specifically for Volvo FL12 trucks equipped with TD122 engines, this unit features a water-cooled design to maintain thermal stability during long-haul operations. It is characterized by its Ø88.00 mm cylinder bore, a 50 mm stroke, and a 608cm³ swept volume. The unit is gear-driven (through drive) and includes an integrated ESS feature to optimize system performance.

Installation and maintenance guidance

For correct installation, technicians should verify that the water inlet and outlet ports (M16x1,5) align with the engine's coolant circuit. Given the technical specifications of the air inlet (Ø29) and air outlet (M26x1,5), ensure all connections are secured to prevent pressure drops. Proper maintenance of the water cooling circuit is essential to prevent overheating of the valve plate.

Selection and replacement

When replacing this component, always match the mounting flange and gear drive configuration of the original unit to ensure seamless integration with the engine crankshaft.
