7000 104 500 Liner Set for MAN Air Brake Compressors

What does a compressor cylinder liner set do?

A Compressor Cylinder Liner Set is a service kit made up of the liner and sealing components used to restore the cylinder surface along which the piston travels inside an air brake compressor. This kit brings the compression chamber back to original dimensions without replacing the entire housing, making it a highly efficient solution for maintaining pneumatic systems.

Compatible vehicles and engines

This component is compatible with MAN models including ND, SÜ, NÜ, NL, SG, and LION'S CITY, as well as Neoplan Trendliner and Euroliner engines like the D2866. It is also fitted to Van Hool Serie 9 and A-Serie, and Ayats Bravo vehicles. These sets are engineered to withstand high-pressure operating conditions in heavy commercial vehicle applications.

Installation and maintenance

When performing installation, technicians should ensure all surfaces are clean and follow staged-tightening discipline during assembly. Checking the bore diameter and cooling type is essential to ensure a precise fit within the compressor housing. For exact torque specifications, always refer to the vehicle manufacturer's service manual.

Preventing system failure

Maintaining the cylinder liner helps prevent air leakage, pressure loss, and excessive oil consumption. Regular inspection of the liner surface during routine service can prevent sudden system failures in buses and trucks.
