Fixing a Thrown Track on a Kubota: A Step-by-Step Guide

[MikePhua]

Kubota compact track loaders are known for their rugged performance and reliability in demanding environments. However, like all tracked machinery, Kubota machines can experience issues with their tracks, including the track coming off or "throwing." This can happen due to various reasons such as misalignment, damage to components, or improper tension. While it may seem like a major issue, fixing a thrown track is manageable with the right tools and approach. In this article, we will guide you through the process of fixing a thrown track on a Kubota machine.
Common Causes of a Thrown Track
Before diving into the repair process, it’s important to understand the common causes of a thrown track:

1. Track Tension Issues
   If the track is too loose or too tight, it can lead to the track slipping off the rollers or idlers. Proper tension is essential for maintaining the stability of the track.
   
2. Damaged or Worn-Out Components
   Worn-out rollers, idlers, or sprockets can cause the track to lose grip and eventually come off. These components need to be inspected regularly for any signs of wear or damage.
   
3. Misaligned Tracks
   If the track is not properly aligned, it can easily come off during operation. Misalignment can happen due to damage to the undercarriage or improper installation of the track.
   
4. Obstructions or Debris
   Rocks, debris, or foreign objects in the path of the tracks can lead to the track becoming misaligned or throwing off the rollers.
   

Tools You Will Need

• Track jack or hydraulic jack
  
• Wrenches and sockets
  
• Torque wrench
  
• Track alignment tool (if available)
  
• Replacement components (rollers, idlers, etc.) if needed
  
• Grease and lubricant
  
• Safety gear (gloves, goggles, etc.)
  

Step-by-Step Guide to Fixing a Thrown Track

1. Safety First
   Before starting the repair, make sure the machine is on a flat surface and the engine is turned off. Engage the parking brake to ensure the machine doesn't move during the repair. Wear appropriate safety gear, including gloves and safety goggles, to protect yourself from debris and moving parts.
   
2. Lift the Machine
   Use a track jack or a hydraulic jack to lift the machine off the ground. Ensure that the machine is stable and secure before working on it. Raising the machine gives you better access to the track and allows you to move the wheels and rollers freely.
   
3. Inspect the Undercarriage
   With the machine raised, inspect the undercarriage, rollers, sprockets, and idlers for damage or wear. Check the condition of the track and see if there are any visible signs of damage, such as cracks, worn spots, or misalignment. Also, verify that the track tension is within the manufacturer’s specifications.
   
4. Remove the Thrown Track
   If the track has come completely off, you’ll need to remove it. Loosen the tension on the track by adjusting the tensioning bolts or using the track tensioning system. If necessary, use a breaker bar to loosen bolts and remove any parts that are obstructing the removal of the track. Once the tension is released, carefully lift the track out of place.
   
5. Check the Track for Damage
   While the track is off, thoroughly inspect it for any damage. Look for worn-out sections, damaged links, or broken parts. If the track is too damaged, it may need to be replaced. However, if the damage is minimal, you can reinstall the track after making necessary adjustments.
   
6. Align the Track
   Check the alignment of the track and the undercarriage. If the track is misaligned, use a track alignment tool to align it correctly. Misalignment can be caused by worn or bent components, so ensure that everything is properly aligned before proceeding.
   
7. Reinstall the Track
   Place the track back onto the rollers and sprockets, ensuring it fits into the tracks properly. As you install the track, carefully check that it is aligned correctly and that the rollers are moving freely. Slowly rotate the track while manually guiding it to make sure it is seated properly on all components.
   
8. Adjust the Track Tension
   Once the track is back in place, adjust the tension using the track tensioning system or bolts. Make sure the track is neither too loose nor too tight. The correct tension should allow the track to move freely while maintaining a firm grip on the rollers and sprockets.
   
9. Test the Track
   Lower the machine back to the ground, remove the jack, and test the track by driving the machine for a short distance. Listen for any unusual noises or vibrations that could indicate an issue with the track. Ensure that the track is moving smoothly and remains in place during operation.
   
10. Final Inspection
    After the test drive, conduct a final inspection of the track and undercarriage. Ensure that all bolts are tightened to the recommended torque specifications. Lubricate the track components and any moving parts to ensure smooth operation and prevent further issues.
    

Preventing Future Track Issues

1. Regular Maintenance
   Perform regular inspections of the undercarriage, rollers, and sprockets to catch any wear or damage before it leads to a thrown track. Clean debris and dirt from the undercarriage regularly.
   
2. Proper Track Tensioning
   Keep the track tension within the manufacturer’s specifications. Over-tightening or loosening the track can lead to premature wear and failure.
   
3. Address Worn Components
   If you notice any parts such as rollers, sprockets, or idlers showing signs of wear, replace them immediately. Worn components can contribute to a thrown track and other issues.
   

Conclusion
Fixing a thrown track on a Kubota machine is a manageable task that can be done with the right tools and knowledge. By following these steps, you can successfully repair the track and prevent further issues. Regular maintenance and attention to detail can help ensure that your Kubota track loader runs smoothly and efficiently for years to come.
