2233637 Single Cylinder Compressor for Caterpillar Engines

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as the primary source of compressed air for the pneumatic braking system in heavy commercial vehicles. It operates by drawing intake air and compressing it to the required pressure levels, ensuring the air processing unit and tanks remain fully charged for safe braking performance. Built with high-strength components, this unit is engineered to withstand the intense thermal and mechanical stresses found in heavy-duty engine environments.

Engine compatibility and fitment

The compressor is specifically designed to be compatible with Caterpillar engines, including the C7, C9, C11, C13, C15, and C18 series. This water-cooled model utilizes the engine's cooling circuit to maintain optimal operating temperatures during sustained high-load operations, which is critical for preventing premature component wear and maintaining consistent air output.

Technical specifications and installation

Technical specifications include a 92.00 mm cylinder bore and a 54 mm stroke, resulting in a swept volume of 360cm³. The unit features a water inlet and outlet port of 3/4’’-16 UNF and an air unloader port of 1/8’’-27 NPT. For installation, technicians should verify that the water cooling lines are properly connected to prevent overheating.

Maintenance and troubleshooting

Regular inspection of the water-cooled valve plate and intake ports is recommended to ensure maximum efficiency. Maintaining clean coolant flow and checking for leaks at the 7/8’’-14 UNF air inlet port will help extend the service life of this essential component. Consult your authorized distributor for compatibility confirmation.
