2233637 C9 Compressor for Caterpillar Engines

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a vital component in the pneumatic system of heavy commercial vehicles, providing the necessary compressed air for braking operations. Designed for high-performance requirements, this water-cooled unit is engineered to maintain stable pressure even under sustained heavy-duty loads by utilizing the engine's cooling circuit to prevent overheating.

Compatible engines and fitment

The unit is specifically compatible with Caterpillar engines, including the C7, C9, C11, C13, C15, and C18 series. This ensures precise fitment and reliable performance within the engine's pneumatic architecture. It is built to meet rigorous industrial standards for durability and consistent air output.

Technical specifications and installation

Technicians should note the specific technical configuration: this model features a Ø92.00 bore and a 54 mm stroke, resulting in a 360cm³ swept volume. It includes an air unloader port (1/8’’-27 NPT) and is equipped with a water-cooled valve plate to enhance thermal management. Proper installation involves ensuring secure connections at the 7/8’’-14 UNF inlet and the 3/4’’-16 UNF water ports.

Maintenance and troubleshooting

Regular inspection of the air outlet port and water inlet/outlet seals is recommended to prevent pressure drops or leaks in the pneumatic circuit.
