Common Use Case or Symptoms: Use when sprocket teeth are hooked, pointed, or worn beyond the manufacturer's service limit — worn sprocket teeth improperly engage with track drive lugs, accelerating track wear, causing track slip, and reducing traction and travel performance on applicable Cat compact track loaders. Always replace both sprockets when installing new tracks to maximize track life.
