923 250 Volvo & Renault Compressor Cylinder Liner

What does a compressor cylinder liner do?

This compressor cylinder liner is a critical component within the air brake compressor assembly, serving as the inner wall of the compression chamber. It provides the necessary surface for the piston to travel, ensuring efficient air pressurization for the braking system. Manufactured with high-strength components, it is designed to withstand intense thermal and mechanical stress during continuous operation.

Compatible vehicles and engines

This part is compatible with various heavy commercial vehicle applications, including Volvo models such as the FMX, FH (FH4/FH5), VNL, FM, B13R, B11R, and FH16, specifically fitting D13K, D11K, D13, D16K, and D11 engines. It is also fitted to Renault Trucks T and C series vehicles with DTI13 or DTI11 engines and Mack Anthem units with MP8 engines. Additionally, it is compatible with Voith systems.

Installation and maintenance

When installing this liner, technicians should ensure the cylinder bore is free of debris and inspect the piston rings for wear to prevent future air leakage or oil consumption. Proper seating of the liner within the compressor block is vital to maintain a secure seal under high-pressure conditions.

Troubleshooting and selection

Regular inspection of the cylinder surface can help identify early signs of scoring or uneven wear. Replacing a worn liner can restore consistent air pressure to the braking system without requiring a full compressor replacement.
