Function & Performance

• Delivers consistent high-pressure flow for all excavator hydraulic systems
• Proportional control valves use pump output for smooth, responsive machine operation
• Efficient gear design minimizes noise and vibration

Installation Notes

• Drain and flush hydraulic system with clean ISO VG 46 before installation
• Prime new pump with fresh hydraulic fluid
• Verify SAE flange coupling alignment (critical for smooth operation)
• Install new input shaft seal and output port gaskets
• Set system relief valve to 16 MPa
• Bleed air from pump after connection
• Run engine at idle for 2–3 minutes before full operation

Maintenance

• Hydraulic fluid: Change every 500 operating hours
• Fluid filter: Replace every 250 hours
• Pressure test: Every 100 hours (confirm 16 MPa under load)
• Noise monitoring: Listen for grinding (sign of gear wear)
• Seal inspection: Check for slow oil weeping at shaft seal
