25 03 10 WABCO Cylinder Head, Air Brake Compressor Repair Kits

The cylinder head serves as a critical component within the air brake compressor system, providing the necessary structural integrity and sealing for optimal compression cycles. Manufactured with heavy-duty grade materials, this component ensures consistent air pressure delivery, which is essential for the safety and reliability of the vehicle's pneumatic braking system.

25 03 10 is the OE-equivalent of the CUMMINS 4936226 and WABCO 911 153 920 2 cylinder head used in CUMMINS M11, ISCE, ISLE, N14, ISC, ISL, QSL9, ISM, and QSL engines. This high-strength component is specifically designed to meet the rigorous demands of heavy commercial vehicle engine architectures where air compressor efficiency is paramount.

Workshop technicians should verify the precise fitment against existing engine serial numbers before installation. Maintaining proper seal integrity during the assembly of the air brake compressor repair kit is crucial to prevent pressure drops. Regular inspection of the cylinder head surface and seating area during routine maintenance can help prevent system failures and ensure long-term durability in heavy-duty environments.
