3. Common Travel Relief Valve Failure Troubleshooting

• Fault 1: Excavator Slow Travel Speed & Unilateral Weak Travel
  Cause: Internal spool wear, spring fatigue, dirt trapped inside valve clearance.
  Solution: Install brand‑new Travel Relief Valve, flush hydraulic circuit and replace hydraulic filter.
• Fault 2: Travel Jitter & Unstable Travel Circuit Pressure
  Cause: Valve core abrasion, internal spring performance degradation.
  Solution: Fit Travel Relief Valve, thoroughly clean the whole hydraulic oil circuit.
• Fault 3: Hydraulic System Overheat & Abnormal Working Noise
  Cause: Internal component wear, oil passages blocked by hydraulic contamination.
  Solution: Replace complete travel relief valve assembly, check hydraulic oil cleanliness.
• Fault 4: Oil Leakage At Travel Relief Valve Mounting Position
  Cause: Seal ring aging, mating surface scratch damage.
  Solution: Replace full travel relief valve assembly or matching seal repair kit.
