3965888 Single Cylinder Compressor for ISLe Engines

What does a single cylinder compressor do?

This single cylinder air brake compressor is a vital component designed to provide the necessary compressed air for heavy commercial vehicle braking systems. Utilizing a high-strength piston design, it works by drawing in air and compressing it to feed the air processing unit and storage tanks. This specific model is engineered to withstand rigorous operating conditions while maintaining consistent pressure delivery.

Compatible engines and fitment

This unit is compatible with Cummins engines, specifically the ISBe, ISDe, and ISLe series. It is designed to integrate seamlessly within the engine's cooling circuit to manage thermal loads during operation. The design ensures efficient air production for various heavy commercial applications, including trucks and construction machinery.

Technical specifications and installation

Technicians should note the specific port configurations: an M26x1.5 air inlet port, an M22x1.5 air outlet port, and an M10x1 unloader port. The unit features water-cooled ports (M16x1.5) to facilitate integration with the engine cooling system. When performing maintenance, ensure all connections are secure and the water flow remains unobstructed to prevent overheating.

Maintenance and troubleshooting

Regular inspection of the valve plate and unloader function is recommended to maintain optimal system performance. If air pressure build-up slows or the compressor fails to unload, a thorough check of the water-cooled valve plate and inlet ports is advised.
