2233637 Caterpillar Compatible C13 Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a piston-type component designed to provide the essential compressed air required for the pneumatic braking systems in heavy commercial vehicles. By utilizing a high-strength single-cylinder housing, it ensures reliable air generation under demanding operational conditions. This unit is specifically engineered to integrate seamlessly with Caterpillar engine architectures to maintain consistent system pressure.

Engine compatibility and fitment

This water-cooled compressor is compatible with Caterpillar engines, including the C7, C9, C11, C13, C15, and C18 models. It is designed to function within the engine's cooling circuit to prevent overheating during sustained heavy-duty use, ensuring the longevity of the internal components. The unit features a 360cm³ swept volume and a through-drive configuration for efficient power transfer.

Installation and maintenance

Installation and maintenance should be performed by a qualified workshop technician. Proper connection to the water inlet and outlet ports (3/4’’-16 UNF) is critical to ensure effective thermal regulation. Regular inspection of the air inlet (7/8’’-14 UNF) and outlet (3/16’’-12 UN) connections is recommended to prevent leaks that could compromise the braking performance of the vehicle.

Troubleshooting and selection

When replacing an old unit, ensure that the unloader port (1/8’’-27 NPT) and ESS features are correctly aligned with the existing system requirements to maintain optimal pressure regulation.
