K118684X00 KNORR-BREMSE Single Cylinder, Air Compressor

The single cylinder air compressor is a critical component within the pneumatic system of heavy commercial vehicles, ensuring consistent air pressure for braking and suspension functions. This unit is engineered with high-strength components to maintain optimal performance under demanding operating conditions. The water-cooled design provides efficient thermal management to extend the service life of the internal mechanisms.

K118684X00 is the OE equivalent of the KNORR-BREMSE K118684X00 Single Cylinder, Air Compressor used in KNORR-BREMSE systems. This part features a cylinder bore of Ø92.00 and a stroke of 54 mm, providing a swept volume of 360cm³. The assembly includes an M26x1,5 air inlet and outlet port, alongside M16x1,5 water ports for precise integration into the vehicle's cooling system.

Workshop technicians should ensure that the water inlet and outlet ports are free from debris during installation to maintain proper cooling. Regular inspection of the water-cooled valve plate and checking the tightness of the M26x1,5 connections is recommended during routine maintenance intervals. This component is designed specifically for heavy commercial vehicle applications requiring high-durability pneumatic solutions.

Proper maintenance of the air compressor system helps prevent pressure drops in the braking circuit. Ensuring that the through-drive mechanism is correctly aligned during assembly will prevent premature wear and optimize the 360cm³ displacement performance.
