51541007121 MAN TGA 40.440 Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent pneumatic pressure within the heavy commercial vehicle braking system. Designed for high-stress environments, the component utilizes high-strength components to ensure reliable operation of the air supply system. The unit is specifically optimized for water-cooled applications to maintain thermal stability during intensive duty cycles.

51541007121 is the OE equivalent of the MAN 51.541.00.7121 single cylinder air compressor used in the MAN TGA 40.440. This precision-engineered part ensures seamless integration with existing pneumatic architectures, maintaining the required air volume and pressure for heavy-duty truck operations.

The assembly features a Ø92.00 mm cylinder bore and a 54 mm stroke, providing a swept volume of 360cm³. It includes dedicated M26x1,5 ports for air inlet and outlet, as well as M16x1,5 ports for water cooling management. Workshop technicians should verify all connection points and ensure the water-cooled valve plate is properly integrated into the cooling circuit during installation.

Regular maintenance of the cooling system and checking the integrity of the M26x1,5 air ports are essential for long-term reliability. Proper fitment in the MAN TGA 40.440 model ensures that the pneumatic braking system receives stable air pressure without interruption.
