A020701801SP1 Single Cylinder Compressor for Mercedes-Benz

What does a single cylinder compressor do?

This single cylinder air brake compressor serves as a critical component in the pneumatic system of heavy commercial vehicles. By utilizing a single-piston design, it compresses intake air to provide the necessary pressure for the air processing unit and subsequent brake tank inflation. This component is engineered with high-strength components to ensure durability under constant pressure cycles.

Vehicle compatibility and technical specifications

This specific model is compatible with Mercedes-Benz vehicles. It is designed as a water-cooled unit to maintain optimal operating temperatures during heavy-duty service. The assembly features an Ø85.00 mm cylinder bore and a 62 mm stroke, providing a swept volume of 352cm³ to meet the air demand requirements of the vehicle's braking circuit.

Installation and maintenance guidance

For proper maintenance, technicians should inspect the water inlet and outlet ports (M14x1,5) for any signs of leakage or scale buildup. Ensuring the cooling lines are clear is vital for the longevity of the water-cooled valve plate. Regular checks of the air inlet (M26x1,5) and outlet (Ø30) connections are recommended to prevent pressure drops in the braking system.

System reliability and selection

When replacing this unit, verify that the through-drive configuration matches the existing engine setup to ensure seamless integration into the drive mechanism.
