781 251 Cylinder Liner for Renault Trucks Compressors

What does a compressor cylinder liner do?

This compressor cylinder liner is a critical component used to restore the internal bore where the piston travels within an air brake compressor. By providing a high-strength surface for the piston rings, it helps prevent air leakage and maintains consistent pressure within the pneumatic system.

Vehicle and engine compatibility

This part is specifically designed for various Renault Trucks models, including the G, KERAX, MAGNUM, PREMIUM 2, PREMIUM, and R series. It is also fitted to KamAZ vehicles and is compatible with Knorr-Bremse systems. This component ensures reliable performance in heavy commercial vehicle applications.

Installation and maintenance

When installing this liner, technicians should inspect the piston rings and sealing components to ensure a complete restoration of the compression chamber. Proper fitment is essential to prevent oil consumption and maintain the air pressure required for braking systems.

System performance

Regular inspection of compressor components can prevent significant pressure loss in the pneumatic circuit. For optimal results, ensure all surfaces are clean and meet the required tolerances during assembly.
