7000 108 300 Mercedes-Benz CONECTO (O 345) Compressor Liner

What does a cylinder liner do?

This cylinder liner serves as a critical component within the air brake compressor, providing the precise surface through which the piston travels. By restoring the cylinder bore to its original dimensions, this part helps prevent air leakage and pressure loss in the braking system. It is engineered using high-strength components to ensure durability under heavy commercial vehicle operating conditions.

Vehicle and engine compatibility

This specific part is compatible with Mercedes-Benz CONECTO (O 345) models, including the M, CONECTO C, H, and UE variants equipped with OM 447 HLA engines. It functions as a vital replacement part for maintaining the integrity of the compression chamber in bus applications.

Installation and maintenance

When installing this liner, technicians should ensure that all surfaces are free of debris to prevent premature wear. Proper seating within the compressor housing is essential to maintain seal integrity and prevent oil consumption. For specific assembly tolerances, always refer to the vehicle manufacturer's service guidelines.

Troubleshooting and selection

Regular inspection of the cylinder walls can help identify signs of wear before they lead to complete system failure. Replacing a worn liner is often a more efficient way to restore compressor capacity than replacing the entire unit.
