Kubota Track Adjuster Access and Maintenance

[MikePhua]

Introduction
Kubota's mini excavators, such as the KX and U series, are renowned for their durability and performance. A critical component in maintaining optimal performance is the track adjuster, which ensures proper track tension. Accessing and maintaining the track adjuster is essential for the longevity of the equipment.
Understanding the Track Adjuster
The track adjuster is a hydraulic component that maintains the correct tension in the rubber tracks. It typically consists of a grease-filled cylinder that extends or retracts to adjust the track tension. Proper tension is crucial to prevent track slippage and uneven wear.
Accessing the Track Adjuster
To access the track adjuster on Kubota mini excavators:

1. Locate the Access Panel: Find the access panel on the side of the track frame, positioned between the idler and the front bottom roller.
   
2. Remove the Panel: Use appropriate tools to remove the panel, exposing the track adjuster grease fitting.
   
3. Inspect the Grease Fitting: Ensure the grease fitting is clean and free from debris.
   

Adjusting Track Tension
To adjust the track tension:

1. Release Track Tension: Insert a grease gun into the grease fitting and pump grease into the track adjuster to extend the cylinder, tightening the track.
   
2. Check Track Tension: After adding grease, check the track tension. The track should have a slight sag but not be loose.
   
3. Re-tighten if Necessary: If the track is too loose, add more grease until the desired tension is achieved.
   

Maintenance Tips

• Regular Inspection: Periodically check the track adjuster for signs of wear or damage.
  
• Clean Grease Fittings: Keep grease fittings clean to ensure proper lubrication.
  
• Use Quality Grease: Use high-quality grease to prevent contamination and ensure smooth operation.
  

Troubleshooting

• Difficulty Adding Grease: If grease cannot be added, the grease fitting may be clogged or damaged. Clean or replace the fitting as necessary.
  
• Track Continues to Slip: Persistent track slippage may indicate a worn track adjuster or seals. Inspect and replace components as needed.
  

Conclusion
Proper access and maintenance of the track adjuster are vital for the performance and longevity of Kubota mini excavators. Regular inspection and timely adjustments can prevent costly repairs and downtime. By following the outlined procedures and maintenance tips, operators can ensure their equipment remains in optimal condition.
