Function
- Primary circuit: Powers boom, arm, bucket hydraulic cylinders
- Secondary circuit: Low-pressure pilot supply for proportional control valves
- Gear design: Smooth, quiet operation with minimal pulsation
Installation Notes
- Flush hydraulic reservoir and all lines with clean ISO VG 46 before installation
- Prime pump with fresh hydraulic fluid (prevents cavitation)
- Inspect SAE flange coupling for proper alignment
- Install new input shaft seal and output gaskets
- Adjust system relief valve to exactly 16 MPa (use calibrated pressure gauge)
- Bleed air from pump casing after connecting engine
- Run engine at idle only for first 2–3 minutes (allow pressure to stabilize)
- Full load test after warm-up (listen for grinding, check pressure steady)
Maintenance Schedule
- Hydraulic Fluid: Change every 500 operating hours or 6 months
- Fluid Filter: Replace every 250 hours (before intervals when working in dust)
- Pressure Check: Verify 16 MPa under load at every 100-hour service
- Noise Inspection: Listen for grinding/cavitation (indicates wear or air in system)
- Seal Inspection: Check shaft seal monthly for slow oil weeping
