Product Overview

The Kawasaki P-29033401321 Outer Differential Spring is a genuine, high-precision OEM replacement part designed for the specialized control modules of Kawasaki K3VL Series axial piston pumps. Located within the pump’s regulator housing, this outer compression spring works in direct tandem with the inner differential spring to maintain accurate pilot-pressure thresholds for load-sensing and pressure cut-off functions. By providing consistent mechanical resistance, it stabilizes hydraulic displacement and ensures immediate response times under heavy, fluctuating system workloads.
