912 514 003 0 WABCO Twin Cylinder, Air Compressor

The air brake system relies on high-quality components to ensure consistent pressure and operational safety. This twin cylinder air compressor is engineered to provide stable pneumatic output within the braking system. Designed for heavy commercial vehicle applications, it features a robust construction to withstand demanding workshop environments and long-term service cycles.

The 9125140030 is the OE equivalent of the WABCO 912 514 003 0 air compressor used in heavy-duty systems. This specific model is characterized by a Ø85.00 mm cylinder bore and a 56 mm stroke, providing a swept volume of 636cm³. It is fully compatible with WABCO systems and follows strict engineering standards for reliability in air brake compressors.

Technical specifications include an M16x1,5 air inlet port and an M26x1,5 air outlet port. The unit is water-cooled (W) to maintain optimal operating temperatures, utilizing M16x1,5 ports for both water inlet and outlet. The inclusion of a through-drive mechanism and ESS feature ensures seamless integration into the existing pneumatic architecture.

Maintenance technicians should regularly inspect the water cooling connections and port integrity to prevent system pressure drops. Ensuring that the water inlet and outlet paths are unobstructed is vital for the longevity of the compressor in heavy commercial vehicle fleets.
