   • Loose or broken track bolts
     
   • Uneven wear on the sprockets
     
   Solution: Regularly inspect the undercarriage for signs of wear. If the tracks are worn out, they may need to be replaced. Lubricating the track rollers and ensuring the track bolts are tightly secured can prevent further damage.
   
5. Bucket or Arm Failures
   Issues with the bucket or arm of the Komatsu PC130 can also arise over time, especially with heavy or improper use. Common symptoms include:
   • Unusual noises when operating the arm
     
   • Loss of function in the bucket or arm movement
     
   • Bent or cracked components
     
   Solution: Inspect the arm and bucket regularly for any signs of damage, especially if you hear unusual sounds during operation. If you notice any bent components, they may need to be straightened or replaced. In cases of serious wear or cracks, professional repair or part replacement might be required.
   

1. Regular Maintenance
