3. Common Conversion Valve Failure Troubleshooting

• Fault 1: Oil‑circuit Switching Failure, Function Cannot Switch
  Cause: Internal spool wear, valve core jammed by hydraulic impurities, shifting mechanism abrasion.
  Solution: Install brand‑new Conversion Valve, flush hydraulic circuit and replace hydraulic filter element.
• Fault 2: Unresponsive Switching Operation, Handle Stiff
  Cause: Internal mechanical parts wear, impurity deposit inside valve chamber.
  Solution: Fit new Conversion Valve, fully clean the whole hydraulic oil circuit.
• Fault 3: Valve Body & Mounting Position Oil Leakage
  Cause: Seal ring aging, mating surface scratch damage, fastener loose.
  Solution: Replace complete conversion valve assembly, check mounting flatness and tighten bolts evenly.
• Fault 4: Hydraulic Pressure Abnormal After Switching
  Cause: Internal spool abrasion, oil passages contaminated by hydraulic dirt.
  Solution: Replace full conversion valve assembly, inspect hydraulic oil cleanliness.
