7000 603 500 Volvo & Renault Compressor Cylinder Liner Set

What does a compressor cylinder liner set do?

A compressor cylinder liner set is a specialized service kit designed to restore the internal cylinder surface where the piston travels within an air brake compressor. By providing a fresh, precise bore, this component helps prevent air leakage and pressure loss caused by worn surfaces. This set is an essential component for maintaining the pressure-generating capacity of pneumatic systems in heavy commercial vehicles.

Compatible vehicles and engines

This high-strength component is compatible with Volvo models including FH, FMX, VNL, FM, B11R, B13R, and FH16, as well as Renault Trucks T, C, and K series. It is engineered to support various engine configurations such as the D11K, D13K, D16K, D13, DTI13, and DTI11. These liners are also compatible with Voith systems.

Installation and maintenance guidance

During installation, workshop technicians should ensure that the cylinder bore is completely free of debris to maintain a proper seal. When replacing worn liners, it is critical to check the condition of the piston rings and seals to ensure full system integrity. Maintaining clean assembly practices helps prevent premature wear of the new liner surface.

Maintenance benefits

Replacing only the liner set is a highly efficient way to overhaul a compressor without replacing the entire housing. This approach ensures the compression chamber returns to original dimensions, restoring reliable braking performance for trucks and buses.
