51541009231 MAN LIONS CITY A 20 Air Compressor

This single cylinder air compressor serves as a critical component within the pneumatic braking and suspension systems of heavy commercial vehicles. Designed to deliver consistent air pressure, the unit utilizes a high-strength component architecture to maintain durability during intensive operation cycles. The integration of a water-cooled system helps manage thermal loads, ensuring the longevity of the internal valve plate and cylinder assembly.

51541009231 is the OE-equivalent air compressor used in the MAN LIONS CITY A 20. This component matches the technical specifications of the MAN 51.54100-9231, providing seamless compatibility with original braking system architectures. The design features a precise Ø92.00 mm bore and a 360cm³ swept volume to meet rigorous industrial standards for heavy-duty transport applications.

For workshop technicians, this unit is designed for straightforward assembly with specific port dimensions: the air inlet and outlet both utilize M26x1,5 threading, while the water inlet and outlet ports are sized at M16x1,5. The through-drive configuration and water-cooled valve plate ensure compatibility with existing cooling lines in the vehicle engine bay. Proper maintenance of the cooling channels is recommended to ensure optimal performance during long-haul service intervals.

When replacing a faulty compressor, verify that the existing hose connections match the M26x1,5 and M16x1,5 specifications to prevent leaks or pressure drops. This part is specifically engineered to restore full pneumatic capacity to the vehicle's air brake system, ensuring safety and reliability for fleet operators.
