3. Common Main Relief Valve Failure Troubleshooting

• Fault 1: Excavator Digging Force Weak, System Pressure Low
  Cause: Internal spool wear, spring fatigue, dirt impurity trapped inside valve clearance.
  Solution: Install brand‑new No‑OEM‑PC200‑6‑Main‑Relief‑Valve Main Relief Valve, flush hydraulic circuit and replace hydraulic filter.
• Fault 2: Obvious Hydraulic Overflow Noise During Operation
  Cause: Valve core abrasion, pressure‑regulating spring performance degradation.
  Solution: Fit PC200‑6 No‑OEM‑PC200‑6‑Main‑Relief‑Valve Main Relief Valve, thoroughly clean whole hydraulic oil loop.
• Fault 3: System Pressure Unstable, Working Action Intermittent
  Cause: Internal component wear, oil passages blocked by contamination.
  Solution: Replace complete main relief valve assembly, inspect hydraulic oil cleanliness status.
• Fault 4: Oil Leakage On Main Relief Valve Mounting Surface
  Cause: Seal ring aging, mating surface scratch damage.
  Solution: Change full main relief valve assembly or matching seal repair kit.
