20774383 Compatible Twin Cylinder Compressor for Volvo FM13

What does a twin cylinder compressor do?

This twin cylinder air compressor plays a critical role in the pneumatic braking system of heavy commercial vehicles by providing consistent air pressure. Built with high-strength components, it ensures reliable operation under demanding service conditions. The unit is designed to withstand high thermal loads through an efficient water-cooling mechanism.

Vehicle and engine compatibility

This specific model is compatible with Volvo FM13 trucks equipped with D13C engines. It functions as a high-performance replacement for original equipment, ensuring seamless integration within the existing air brake architecture of the vehicle. The design focuses on maintaining stable pressure levels for the entire pneumatic circuit.

Technical specifications and installation

The technical configuration includes an Ø85.00 mm cylinder bore and a 56 mm stroke, resulting in a 636cm³ swept volume. For installation, note the M26x1,5 air outlet port and M16x1,5 ports for water inlet and outlet. Proper torque application on all threaded connections is essential to prevent leaks during operation.

Maintenance and troubleshooting

To ensure longevity, technicians should regularly inspect the water cooling lines and check for any signs of oil contamination in the air circuit. Maintaining the integrity of the unloader port and ensuring clean coolant flow will prevent premature wear of the internal valve plate.
