4980796 Single Cylinder Compressor for ISLe Engines

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic system of heavy commercial vehicles, generating the compressed air required for braking and air-operated functions. It is engineered with high-strength components to withstand the intense thermal and mechanical stresses found in heavy-duty environments.

Engine and system compatibility

This specific model is compatible with Cummins ISLe engines, including ISBe and ISDe variants. It is specifically designed to integrate seamlessly with the engine's cooling circuit to manage operating temperatures effectively during sustained operation.

Technical specifications and installation

Technicians should note that this unit features a water-cooled valve plate and a through-drive configuration. The technical specifications include an Ø80.00 mm cylinder bore, a 45mm stroke, and specific port sizes: M26x1.5 for air inlet, M22x1.5 for air outlet, and M16x1.5 for water inlet/outlet, ensuring precise fitment.

Maintenance and troubleshooting

To maintain optimal performance, regular inspection of the water cooling lines and air port connections is recommended. Maintaining clean air intake and checking the unloader port integrity can prevent system pressure drops during heavy-duty use.
