442 130 0108 Mercedes-Benz OM 447 HLA Liner Set

What does a cylinder liner set do?

This cylinder liner set is a precision component designed to restore the internal cylinder surface where the piston travels within an air brake compressor. By replacing worn liners, technicians can effectively address issues like air leakage and pressure loss without needing to replace the entire compressor unit. This set is engineered using heavy-duty grade materials to withstand the intense thermal and mechanical stresses found in heavy commercial vehicle braking systems.

Compatible Mercedes-Benz models and engines

This specific liner set is compatible with Mercedes-Benz CONECTO (O 345) trucks, including M, H, UE, and CONECTO C variants equipped with OM 447 HLA engines. It ensures a precise fit within the compression chamber to maintain optimal volumetric efficiency. The component is essential for maintaining the air pressure required for reliable braking performance in bus and truck applications.

Installation and maintenance guidance

When performing installation, it is vital to ensure all surfaces are free of contaminants and that the liner is seated according to the manufacturer's specifications. Proper assembly prevents premature wear of the piston rings and maintains the integrity of the seal. For exact torque requirements during assembly, always refer to the vehicle manufacturer's service manual.

Troubleshooting compressor performance

Monitoring compressor performance for signs of oil consumption or pressure drops can help determine when a liner replacement is necessary. Maintaining the compressor system through high-strength components helps prevent unexpected downtime in fleet operations.
