Purchase and Maintenance Guidelines
1. Code Verification: Ensure 897603-0040 + B229900004401 to avoid confusion with 4HK1/6WG1 crankshafts (completely different dimensions and strokes).
2. Installation Requirements:
- When replacing the crankshaft, main bearings, connecting rod bearings, thrust washers, and crankshaft oil seals must be replaced simultaneously to prevent bearing failure due to poor new-old mating.
- Installation torque must strictly follow manufacturer standards (main bearing bolts approximately 180N·m + 90°, connecting rod bolts approximately 100N·m + 90°), tightening diagonally in stages.
3. Fault Diagnosis:
- Engine noise, low oil pressure, journal scoring / excessive ovality all require inspection or replacement of the crankshaft.
- Used crankshafts should be inspected for journal wear, cracks, and runout; it is recommended to perform flaw detection and dynamic balancing tests.
4. Upgrade Recommendations:
- For long-term heavy-duty operation, it is advisable to choose original factory or high-quality forged crankshafts to avoid fracture of cast parts under heavy loads.
