5286661 Cummins Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a vital component in the air brake system of heavy commercial vehicles, utilizing two piston-cylinder assemblies to generate consistent compressed air. Engineered for durability, this unit is designed to withstand high-pressure environments within the braking system of heavy-duty machinery and vehicles.

Engine compatibility and technical specifications

This specific model is compatible with Cummins engines, including the ISC8.3, QSC8.3, ISL, and QSL9 series. It features a Ø75.00 mm cylinder bore and a 56 mm stroke, delivering a swept volume of 495cm³. The unit is designed with a water-cooled configuration (W) to manage thermal loads effectively during continuous operation.

Installation and maintenance guidance

For proper installation, technicians should verify the water inlet and outlet ports, which are specified at 3/4-16 UNF. The air outlet port features an M27x2 thread, while the air unloader port is M10x1. This through-drive unit ensures efficient mechanical integration with the engine crankshaft.

Operational efficiency and checks

To maintain optimal braking performance, check the water cooling lines and air inlet ports regularly for leaks or debris. Proper lubrication and adherence to service intervals will help maintain the integrity of the water-cooled valve plate and internal components.
