3. Common Anti‑Swing Valve Failure Troubleshooting

• Fault 1: Excavator Slewing Jitter & Swing Shaking
  Cause: Internal spool wear, seal damage, hydraulic impurity jamming valve core clearance.
  Solution: Install brand‑new Anti‑Swing Valve, flush hydraulic circuit and replace hydraulic filter element.
• Fault 2: Loud Impact Noise While Stopping Slew Rotation
  Cause: Valve core abrasion, internal buffer spring fatigue and performance degradation.
  Solution: Fit new Anti‑Swing Valve, fully clean the whole hydraulic oil circuit.
• Fault 3: Unstable Rotary Speed & Abnormal Vibration
  Cause: Internal parts wear, oil passages blocked by hydraulic contamination.
  Solution: Replace complete anti‑swing valve assembly, inspect hydraulic oil cleanliness.
• Fault 4: Oil Leakage At Anti‑Swing Valve Mounting Surface
  Cause: Seal ring aging, mating surface scratch damage.
  Solution: Replace full anti‑swing valve assembly or matched seal repair kit.
