A9061305015SP2 Single Cylinder Compressor for Mercedes-Benz

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component within the pneumatic braking system, providing the necessary compressed air for heavy commercial vehicle operation. By utilizing a piston-type mechanism, it converts mechanical energy into high-pressure air required by the air processing unit and storage tanks. This specific model is designed with water-cooling capabilities to maintain optimal operating temperatures during intensive service cycles.

Compatibility and technical specifications

This component is engineered to fit Mercedes-Benz vehicles. It features a single cylinder configuration with a Ø85.00 cylinder bore and a 42 mm stroke, ensuring efficient air output through its 238cm³ swept volume. The unit is designed for water cooling via M14x1,5 inlet and outlet ports, providing enhanced thermal stability compared to air-cooled alternatives.

Installation and maintenance guidance

For proper maintenance, technicians should inspect the M26x1,5 air inlet port and Ø30 outlet port connections regularly to prevent leaks. Ensuring the water cooling lines are free of obstructions is vital for preventing overheating. When replacing this unit, verify the through drive configuration and port dimensions to ensure seamless integration into the existing brake system.

Troubleshooting and system health

Regular monitoring of air pressure levels and checking for excessive oil discharge can help identify potential wear before system failure occurs. Proper installation ensures the longevity of the internal piston and ring assemblies.
