• Fault 1: Journal Scoring & Wear Groove
  Cause: Impurities inside engine oil abrade journal surface.
  Solution: Install brand‑new 4HK1 crankshaft, replace oil filter and clean engine oil passages.
• Fault 2: Main Bearing Burn‑out & Engine Knocking Noise
  Cause: Long‑time heavy‑load operation leads to bearing clearance beyond tolerance range.
  Solution: Equip new crankshaft together with matched main and connecting rod bearing shells.
• Fault 3: Crankshaft Fatigue Crack Risk
  Cause: Engine overloading and abrupt mechanical impact force.
  Solution: Every crankshaft undergoes crack detection before shipment to eliminate breakage hidden danger.
• Fault 4: Front & Rear Oil Seal Recurrent Oil Leakage
  Cause: Wear groove formed on oil‑seal journal results in continuous oil leakage.
  Solution: Replace complete crankshaft together with supporting oil seal kits.
