51541007231 MAN TGS 18.400 Single Cylinder Air Compressor

The single cylinder air compressor is a critical component within the pneumatic systems of heavy commercial vehicles, ensuring consistent air pressure for braking and auxiliary functions. Engineered with high-strength components, this unit provides reliable service under demanding operating conditions. The design focuses on maintaining optimal volumetric efficiency through precision engineering of the cylinder bore and stroke mechanics.

This specific air compressor is the OE equivalent of the MAN 51.54100-7231 part used in the MAN TGS 18.400. It features a Ø92.00 mm cylinder bore and a 54 mm stroke to deliver a swept volume of 360cm³. The unit is specifically designed for water-cooled systems, utilizing M26x1,5 threading for air ports and M16x1,5 for water inlets/outlets to ensure stable thermal management during high-load cycles.

Workshop technicians should note that this component is a single-cylinder, water-cooled unit with a through-drive configuration. Proper installation requires verifying the connection of the M26x1,5 air ports and ensuring the M16x1,5 water cooling lines are secure to prevent overheating. Regular maintenance of the cooling system and checking the air inlet/outlet seals is recommended to ensure long-term system reliability in heavy-duty service environments.
