5003217 SP1 Compatible Twin Cylinder Compressor

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 high-pressure compressed air required for braking and pneumatic operations. By utilizing two piston-cylinder assemblies, this unit provides a higher air output compared to single-cylinder alternatives, ensuring faster reservoir replenishment for demanding heavy-duty applications.

Compatible vehicle and engine fitment

This specific model is designed to fit Volvo N12 trucks equipped with TD122 engines. It is a water-cooled unit featuring a 75.00 mm cylinder bore and a 50 mm stroke, which facilitates efficient thermal management during sustained operation. The air inlet and outlet ports are configured with M26x1.5 threading to ensure secure connections within the pneumatic circuit.

Installation and maintenance guidance

For workshop technicians, correct installation is critical to maintaining system integrity. When replacing this unit, ensure that the water inlet and outlet ports (M16x1.5) are properly aligned with the engine's cooling circuit to prevent overheating. Proper torque application on all mounting points is essential to maintain the seal and prevent pressure leaks.

System reliability and troubleshooting

Maintaining consistent air pressure depends on the integrity of the valve plate and cooling system. Regular checks of the water cooling lines and port connections help prevent premature wear of the internal components, ensuring long-term reliability in service.
