The Cummins Power Steering Pump 4943083 is a high-performance hydraulic pump designed to provide consistent and reliable power steering assistance for Cummins diesel engines. Engineered for Cummins B6.7, ISB/ISD4.5, and ISB/ISD6.7 platforms, this pump ensures smooth steering control under heavy loads and demanding operating conditions.
Manufactured to OEM specifications, the 4943083 power steering pump delivers stable fluid flow and pressure, reducing steering effort while protecting steering gear and hydraulic components from excessive wear. Built with precision-machined internal components and durable seals, it is designed to withstand high operating temperatures, vibration, and continuous duty cycles common in commercial and industrial applications.
A failing power steering pump can cause hard steering, noise, fluid leaks, or inconsistent steering response. Replacing it with the Cummins 4943083 power steering pump restores proper hydraulic performance, improves vehicle handling, and reduces operator fatigue. It is ideal for routine maintenance, steering system repairs, and fleet service operations.
