For Caterpillar E345/E349(CR6594/52;150-4745;231-0841) final drive sprockets, you’re looking for a critical undercarriage component that transfers power from the final drive to the track chain. These sprockets must be extremely durable, especially in heavy-duty applications like mining, quarrying, or large-scale excavation.

Key Features of Cat® E345/E349 Final Drive Sprockets

1. Material & Construction:
   • High-carbon or alloy steel (hardened for wear resistance).
   • Precision-cut teeth for smooth engagement with track links.
   • Sealed bearings & bushings (if part of a complete final drive assembly).
2. Compatibility:
   • Must match E345 or E349 model specs (some variations exist between standard and high-hour applications).
   • Check tooth count, bolt pattern, and shaft diameter before purchasing.
3. Types Available:
   • Segmented sprocket rims (replaceable teeth for cost savings).
   • Solid one-piece sprockets (for maximum durability).
   • Rebuilt/remanufactured (budget-friendly option).

Maintenance Tips for Final Drive Sprockets

✔ Monitor tooth wear (replace if teeth are chipped or excessively worn).
✔ Check track chain wear (a worn chain accelerates sprocket wear).
✔ Inspect seals & lubrication (prevents final drive failure).
✔ Replace in pairs (if one sprocket is worn, the opposite side may be close behind).
