2233636 C18 Single Cylinder Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a piston-type component designed to produce the high-pressure compressed air required for heavy commercial vehicle braking systems. It operates by taking drive from the engine to compress intake air, which is then directed to the air processing unit and storage tanks. This component is a critical link in the pneumatic system, ensuring consistent pressure delivery for safety-critical braking functions.

Engine compatibility and technical specifications

This specific unit is designed for compatibility with Caterpillar C7, C9, C11, C13, C15, and C18 engines. It features a water-cooled design to manage operating temperatures during heavy-duty service, including a water-cooled valve plate and through-drive configuration. The unit includes an ESS feature and specific port sizes: a 7/8’’-14 UNF air inlet, 3/16’’-12 UN outlet, and 3/4’’-16 UNF water ports.

Installation and maintenance guidance

For workshop technicians, maintaining correct port torque and ensuring the cooling system provides steady flow to the water inlet is essential for preventing overheating. When inspecting the unit, check the through-drive connection and air unloader port (1/8’’-27 NPT) for any signs of leakage or debris that could compromise pneumatic performance.

Troubleshooting and selection

Consult your authorized distributor to check the compatibility list.
