This hydraulic pump supplies pressurized fluid to the tractor's hydraulic system, powering implements, steering, and three-point linkage functions. It is a positive-displacement gear pump that draws fluid from the reservoir and delivers it at a regulated flow rate to the control valves and actuators downstream. A worn pump produces symptoms such as slow implement response, reduced lift capacity, or noisy operation due to internal leakage past the gear tips or wear plates. The manufacturer machines the housing and gear set to the same tolerances as the original assembly, so the pump mounts directly to the drive flange without requiring shimming or adapter plates. On installation, ensure the input shaft rotation matches the drive direction and replace the suction-line O-ring to prevent air ingestion.
