0R1623 Caterpillar C11 Compressor Equivalent

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. It functions by compressing intake air to provide the necessary pressure for the braking system and air processing units. Built with high-strength components, this unit ensures consistent air delivery even under demanding operating conditions.

Engine compatibility and fitment

This specific model is designed to be compatible with Caterpillar engines, including the C7, C9, C11, C13, C15, and C18 series. The design incorporates water cooling to maintain optimal operating temperatures and prevent overheating during long-duration service.

Technical specifications and installation

Technicians should note the technical specifications: it features a 92.00 mm cylinder bore, a 54 mm stroke, and a swept volume of 360cm³. The unit includes an ESS feature and is equipped with a water-cooled valve plate. For correct installation, ensure all ports—including the 7/8’’-14 UNF air inlet and 3/4’’-16 UNF water ports—are properly secured to prevent leaks.

Maintenance and troubleshooting

Regular inspection of the air unloader port and cooling lines is recommended to maintain system efficiency. If air pressure builds slowly or leaks are detected near the ports, a thorough inspection of the single cylinder assembly is advised to ensure continued brake performance.
