3944460 Cummins 6CT8.3 Compatible Compressor

What does a single cylinder compressor do?

This single cylinder compressor serves as a critical component within the air brake system, providing the necessary pressurized air required for braking and pneumatic operations. Designed for high-duty cycles, it utilizes a water-cooled mechanism to manage thermal loads effectively, ensuring consistent performance even under sustained heavy-duty operation.

Engine compatibility and fitment

The unit is specifically engineered to be compatible with Cummins engines, including the 6BT5.9, 6CT8.3, ISB, QSB, and C50 series. This ensures seamless integration into existing engine architectures while maintaining the high standards required by professional workshop technicians.

Technical specifications and installation

Technical specifications include a Ø75.00 mm cylinder bore and a 56 mm stroke, resulting in a swept volume of 247cm³. The assembly features an M27x2 air outlet port and M10x1 unloader ports, alongside water inlet and outlet ports sized at 3/4 16UNF to facilitate efficient cooling integration.

Maintenance and system integration

For optimal performance, technicians should verify that the water cooling lines are clear and the unloader ports are free of debris during installation to prevent pressure fluctuations.
