51541056021 MAN ÜL Compressor Cylinder Liner

What does a compressor cylinder liner do?

This compressor cylinder liner serves as a critical component within the air brake compressor assembly, providing the essential surface for piston travel. By maintaining the integrity of the compression chamber, it prevents air leakage and ensures consistent pressure delivery within the pneumatic system. This part is manufactured using heavy-duty grade materials to withstand continuous high-pressure cycles.

Compatible MAN ÜL models

This specific component is designed to fit MAN ÜL models, including the 313 and 363 variants. It is an essential replacement part for maintaining the performance of air brake systems in heavy commercial vehicles. Check the compatibility list for exact fitment.

Installation and maintenance

When replacing the cylinder liner, technicians should inspect the piston rings and sealing components to ensure optimal system performance. Maintaining correct tolerances during installation is vital to prevent premature wear or pressure loss in the braking circuit.

Troubleshooting and replacement

Monitoring air consumption and pressure stability can help identify when a liner requires replacement. Ensuring the cylinder surface remains smooth and properly seated will extend the service life of the entire compressor assembly.
