7000 104 300 MAN Compatible Compressor Cylinder Liner

What does a compressor cylinder liner do?

This compressor cylinder liner is a critical component used to restore the internal cylinder surface where the piston travels within an air brake compressor. By replacing the worn liner, workshop technicians can effectively address issues like air leakage and pressure loss without the need to replace the entire compressor assembly. This component is essential for maintaining the high-pressure output required for reliable braking performance in heavy commercial vehicles.

Compatible vehicles and engines

This part is compatible with several heavy commercial vehicle models, including MAN (LION'S CITY, LION'S CLASSIC, NG, SG, ÜL, ND, NL, SÜ), Neoplan (Euroliner, Trendliner), Van Hool (A-Serie, Serie 9), and Ayats (Bravo). It is specifically suitable for applications involving MAN engines such as the D2866 engine in Neoplan Trendliner models. These liners are designed to withstand high-pressure cycles and thermal stress common in heavy-duty environments.

Installation and maintenance

When performing an overhaul, it is vital to ensure the cylinder bore is clean and free of debris to prevent premature wear of new components. Technicians should verify that the liner dimensions match the specific compressor architecture to ensure a proper seal within the housing. Proper installation helps maintain the volumetric efficiency of the air brake system.

Maintenance and troubleshooting

Regular inspection of the cylinder walls during routine maintenance can help identify early signs of scoring or uneven wear. Addressing these issues early prevents secondary damage to piston rings and seals, ensuring long-term reliability for fleet managers and service providers alike. Check the compatibility list.
