This hydraulic pump delivers pressurized fluid to the tractor's hydraulic system, enabling precise control of implements and auxiliary functions. It is a direct replacement unit from Bosch Rexroth, matching the original pump's displacement and mounting interface so no modifications are needed during installation. The pump's nine-tooth drive gear engages with the engine-driven power take-off to generate flow. A worn pump typically manifests as slow implement response or inability to maintain hydraulic pressure under load. The manufacturer machines the housing and gear set to the same tolerances as the original assembly, preserving the volumetric efficiency that the system's control valves rely on for consistent actuation.
