441 130 01 08 Mercedes-Benz OM 447 HLA Compressor Liner Set

What does a cylinder liner set do?

This cylinder liner set is a critical component used to restore the internal cylinder surface within an air brake compressor. By providing a precision-engineered surface for the piston to travel, it helps maintain optimal compression and prevents air leakage or pressure loss in the braking system. These high-strength components are essential for maintaining the reliability of the pneumatic system in heavy commercial vehicles.

Compatible Mercedes-Benz models and engines

This specific kit is designed for use in Mercedes-Benz CONECTO (O 345) models, including variants such as M, H, UE, and CONECTO C equipped with OM 447 HLA engines. It serves as a direct replacement to restore the compression chamber's integrity without requiring a complete compressor overhaul.

Installation and maintenance guidance

When performing installation, technicians should ensure the cylinder bore and housing surfaces are thoroughly cleaned to prevent contaminants from entering the pneumatic circuit. It is vital to verify that all sealing components are correctly seated during assembly to prevent future pressure drops. Always consult the vehicle manufacturer's service manual for specific torque requirements during installation.

Troubleshooting compressor performance

Regular inspection of the liner surface can help identify early signs of wear, such as increased oil consumption or audible air leaks, allowing for proactive maintenance of the air brake system.
