20429339 SP1 Volvo Compatible 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. By utilizing two piston-cylinder assemblies, it provides a consistent and high-volume air supply required for reliable brake operation and auxiliary pneumatic functions. The unit is constructed with high-strength components to withstand the demanding thermal and pressure cycles found in heavy-duty environments.

Vehicle and engine compatibility

This specific model is engineered for compatibility with Volvo F10 vehicles equipped with TD102 engines. It features a water-cooled design to maintain optimal operating temperatures and includes an ESS feature for enhanced system reliability. The unit is characterized by an Ø88.00 mm bore, a 50 mm stroke, and an air outlet port size of M26x1,5.

Installation and maintenance guidance

For proper installation, technicians should verify that the water inlet and outlet ports (M16x1,5) match the existing engine cooling lines. It is essential to check the through drive configuration and ensure the air unloader port (M22x1,5) is correctly aligned with the vehicle's pneumatic circuit to prevent pressure regulation issues.

Selection and replacement tips

When replacing an existing unit, always compare the mounting flange and drive gear specifications to ensure an exact fit. Regular inspection of the water-cooled valve plate and connection points helps prevent air leaks and maintains peak compression efficiency throughout the service interval.
