51541007121 MAN TGS 40.400 Single Cylinder, Air Compressor

This single cylinder air compressor serves as a critical component in the pneumatic system of heavy commercial vehicles. Designed to provide consistent air pressure, the unit features a robust construction with a Ø92.00 cylinder bore and a 54 mm stroke to maintain optimal swept volume during operation. Its water-cooled design ensures heat management remains efficient even under heavy-duty service conditions.

51541007121 is the OE equivalent of the MAN 51.54100-7121 single cylinder air compressor used in the MAN TGS 40.400. This high-strength component is engineered to meet strict technical standards for seamless integration into the vehicle's braking and pneumatic systems. The part features through-drive capability and specific port dimensions including M26x1,5 for air and M16x1,5 for water inlets/outlets.

For workshop technicians performing maintenance or repairs, this unit is designed for precise fitment within the MAN TGS series architecture. It is essential to verify the port sizes and cooling connections during installation to ensure system integrity. Regular inspections of the water-cooled valve plate and port seals are recommended to prevent pressure drops in the heavy commercial vehicle's air brake system.
