Common Fault and Solution: Excavator Losing Hydraulic Power
Problem: A Komatsu PC200-7 excavator suddenly experiences a significant loss of hydraulic power, making it difficult to operate the boom, arm, and bucket.
Possible Causes:
Low hydraulic oil level: Check the hydraulic oil tank and ensure it is filled to the correct level.
Clogged hydraulic filters: Dirty or clogged filters can restrict the flow of hydraulic fluid. Replace the hydraulic filters according to the manufacturer's recommendations.
Faulty hydraulic pump: The hydraulic pump might be damaged or worn, leading to reduced pressure. This often requires professional inspection and potential replacement.
Leaking hydraulic hoses or cylinders: Inspect all hydraulic hoses and cylinders for any signs of leaks. Repair or replace any damaged components.
Malfunctioning main relief valve: If the main relief valve is stuck open, it can cause a drop in system pressure. Inspect and test the relief valve.
Troubleshooting Steps:
Check the hydraulic oil level and top up if necessary.
Inspect and replace the hydraulic filters.
Visually inspect all hydraulic hoses and cylinders for leaks.
Listen for unusual noises from the hydraulic pump, which could indicate a problem.
If the issue persists, it is recommended to contact a qualified technician to diagnose and repair the hydraulic pump or main relief valve.
Remember to always consult your machine's service manual for specific troubleshooting procedures and safety precautions.
