The Caterpillar E320 Track Chain Assembly (Part Number:590-3447) is a critical undercarriage component designed for Cat 320D2, 320D2 GC, and 320D3 excavators. It serves as the backbone of the track system, transmitting power from the sprocket and final drive while supporting the machine's weight and guiding track movement.

• Reliable Performance
  • Clamp Master Link system ensures secure track shoe attachment
  • No wear sensor (manual inspection required for maintenance)
• Compatibility
  • Fits Cat 320D2, 320D2 GC, and 320D3 excavators

• Ideal for general excavation, grading, and light-to-medium construction work
• Suitable for machines nearing end-of-life or operating in low-abrasion conditions

• Regularly inspect for wear, cracks, or loose bolts
• Ensure proper grease lubrication to prevent premature failure
• Replace if excessive elongation or damage is observed
