361-8851 crankshaft AS CAT spare part

Advantages

• Withstands immense mechanical stresses, vibrations, and thermal loads
• Allows easy access to inspection, replacement, or maintenance when needed
• Integrates offset crankpins and main journals
• Reduces noise and extends the pump’s and surrounding components’ lifespan

1. Forged steel substrate with deep-nitriding treatment; offers high wear and fatigue resistance, suitable for prolonged, continuous, heavy-duty operation.
2. Precision-ground main journals and connecting rod journals with strict roundness tolerances to minimize bearing shell wear.
3. Integrally forged counterweights, factory-calibrated for dynamic balance to reduce overall engine vibration.
4. Precision-machined oil passages ensure unobstructed lubrication flow, guaranteeing stable oil supply during high-speed operation.
5. Manufactured to original equipment (OE) specifications for direct, drop-in replacement—no additional machining required.
