Description

This twin cylinder air compressor is engineered to provide reliable pneumatic pressure within heavy commercial vehicle systems. Designed for high-duty cycles, the component utilizes water cooling to maintain optimal operating temperatures and ensure consistent performance in demanding environments. Its robust construction supports the critical role of air generation for braking and suspension systems.

lk4951 is the OE-equivalent of the KNORR-BREMSE K053643N00, K053643N55, LK4951, LK4951 SP2, and SCANIA 2024412 air compressors. This part is engineered to meet the strict requirements of high-capacity air systems in heavy trucks and buses. By maintaining exact dimensional specifications like the Ø86.00 mm bore and M26x1,5 inlet port, it ensures seamless integration with existing vehicle architectures.

Workshop technicians can rely on the precision of this unit during assembly. The component features a through-drive design and specialized ports including M22x1,5 for air outlet and M18x1,5 for water circulation. Proper installation requires checking the water inlet and outlet connections to ensure efficient thermal management. Regular inspection of the unloader port (M10x1) and the ESS feature functionality is recommended to prevent system pressure fluctuations or overheating during long-haul operations.
