51541056021 MAN NÜ Cylinder Liner for Air Brake Compressors

What does a compressor cylinder liner do?

This compressor cylinder liner is a vital component used to restore the internal cylinder surface within an air brake compressor. By providing a smooth, precise bore for the piston to travel through, it ensures the compression chamber maintains its required pressure and prevents air leakage or oil consumption caused by wear.

Compatible MAN NÜ applications

This specific part is designed for MAN NÜ models, including the 310 and 360 variants. It serves as an economical solution for overhauling the compressor without the need to replace the entire unit, ensuring the braking system operates at peak efficiency.

Installation and maintenance guidance

When performing installation, technicians should ensure all surfaces are clean and follow the manufacturer's torque specifications to maintain proper sealing. Regular inspection of the liner surface during routine maintenance can help prevent sudden pressure loss in the pneumatic system.

Selection and troubleshooting

Selecting a high-strength component ensures long-term reliability under heavy-duty operating conditions. Check the compatibility list to confirm fitment for your specific engine application.
