1916521 Caterpillar Compatible C13 Compressor

What does a single cylinder compressor do?

This single cylinder air brake compressor is a vital component within the pneumatic system of heavy commercial vehicles. It functions by compressing intake air to supply the air processing unit and storage tanks required for reliable braking performance. Built with high-strength components, this unit ensures consistent pressure delivery even under demanding operational cycles.

Engine compatibility and fitment

This specific model is designed for compatibility with Caterpillar engines including the C7, C9, C11, C13, C15, and C18 series. The design incorporates a water-cooled valve plate and through-drive capability to maintain efficiency during sustained heavy-load operations in construction machinery and heavy trucks.

Technical specifications and maintenance

Technicians should note the technical specifications: it features a Ø92.00 mm cylinder bore and a 54 mm stroke, with an air inlet port measuring 7/8’’-14 UNF. The unit is water-cooled via 3/4’’-16 UNF ports to prevent overheating. Regular inspection of the unloader port and air outlet connections is recommended to ensure optimal system pressure.

Installation and performance

Proper installation of this compressor is critical for maintaining the integrity of the entire air brake system. Given its water-cooled nature, ensuring correct coolant flow through the inlet and outlet ports is essential for longevity and preventing premature wear of the internal piston assembly.
