911 553 103 0 WABCO Twin Cylinder, Air Compressor

This high-strength component is engineered to provide consistent air compression for heavy commercial vehicle braking systems. Designed with a robust dual-cylinder architecture, it ensures reliable pneumatic performance under demanding operating conditions. The integration of a water-cooled valve plate and specific port dimensions guarantees optimal thermal management and system stability.

The 9115531030 is the OE equivalent of the WABCO 911 553 103 0 Twin Cylinder, Air Compressor used in WABCO systems. This part features a Ø85.00 mm cylinder bore and a 56 mm stroke to maintain precise swept volume and pressure delivery. It is specifically engineered to meet the rigorous standards required for professional-grade air brake systems.

For workshop technicians, this component features an M26x1,5 air inlet and outlet port along with an M12x1,5 unloader port to facilitate standard installation. Maintenance should focus on ensuring the water cooling ports (M16x1,5) remain unobstructed to preserve the longevity of the through-drive system. Regular inspection of the port seals is recommended during routine service intervals.

Detailed technical verification of the port sizes and compatibility with existing WABCO hardware is essential before installation to ensure seamless system integration.
