Daily Maintenance Recommendations

Hydraulic Oil Inspection

Check:

• Oil level
• Oil contamination
• Oil color
• Metal particles

---

Filter Maintenance

Hydraulic contamination is one of the biggest causes of piston pump failure.

Recommended:

• Replace filters regularly
• Keep hydraulic tank clean
• Avoid dust entering hydraulic lines

---

Temperature Monitoring

Recommended operating temperature:

40°C–70°C

High temperature causes:

• Seal aging
• Reduced lubrication
• Increased leakage

---

Repair Parts Commonly Replaced

During rebuilding, technicians normally replace:

• Seal kit
• Bearings
• Valve plate
• Pistons
• Slipper shoes
• Cylinder block
• Retainer plate
