3. Common Crankshaft Failure Troubleshooting

• Fault 1: Journal Scoring & Deep Wear Groove
  Cause: Contaminated lubricating oil, metal impurities scratch journal surface.
  Solution: Install brand‑new K19 forged crankshaft, replace oil filter and clean engine oil circuit simultaneously.
• Fault 2: Main Bearing Burn‑out & Heavy Engine Knocking Noise
  Cause: Long‑duration overload operation results in bearing clearance out of tolerance.
  Solution: Fit new K19 crankshaft matched with corresponding main and connecting rod bearing shells.
• Fault 3: Crankshaft Fatigue Crack Risk
  Cause: Engine overloading and sudden mechanical impact shock.
  Solution: Our reinforced fillet K19 forged crankshaft, every piece passes non‑destructive crack detection before delivery.
• Fault 4: Front & Rear Oil Seal Recurrent Oil Leakage
  Cause: Oil‑seal mating journal forms wear groove, oil still leaks after changing new oil seals.
  Solution: Replace complete crankshaft together with high‑quality matching oil seal kits.
