1916521 Single Cylinder 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. It operates by compressing intake air to supply the air processing unit, which then distributes pressure to the tanks to ensure consistent braking performance. Designed with high-strength components, it provides the necessary air output required for demanding industrial and transport applications.

Engine compatibility and fitment

This specific model is compatible with Caterpillar engines, including the C7, C9, C11, C13, C15, and C18 series. By maintaining precise pressure levels, it ensures the stability of the entire pneumatic circuit under heavy-duty operating conditions.

Installation and cooling specifications

The unit features a water-cooled design to prevent overheating during sustained use and includes a water-cooled valve plate for enhanced thermal management. Technicians should verify the 7/8’’-14 UNF air inlet and 3/4’’-16 UNF water ports during installation to ensure a leak-free connection and optimal cooling flow.

Maintenance guidance

Regular inspection of the through drive and unloader ports is recommended to maintain peak efficiency and prevent system pressure drops.
