Takeuchi TB135 Track Came Off with No Grease Coming Out

[MikePhua]

Introduction to the Takeuchi TB135
The Takeuchi TB135 is a compact yet powerful mini-excavator, renowned for its versatility and reliability in various construction and landscaping tasks. Introduced in the early 2000s, the TB135 offers a balance between performance and maneuverability, making it a popular choice for operators dealing with confined spaces. Equipped with a 24.8-horsepower engine and a hydraulic system capable of delivering up to 3,000 psi, the TB135 is designed to handle demanding workloads efficiently.
Understanding the Track Tensioning System
The track tensioning system in the TB135 is crucial for maintaining optimal track performance and longevity. It consists of a grease-filled cylinder that adjusts the tension of the track by extending or retracting the idler wheel. This system ensures that the track remains tight enough to prevent slipping but not so tight that it causes excessive wear. Regular maintenance and proper lubrication are essential to keep the tensioning system functioning correctly.
Common Issue: Track Coming Off with No Grease Flow
A reported issue with the TB135 involves the track coming off the undercarriage, accompanied by no grease flowing when the grease fitting is loosened. This situation can be indicative of several underlying problems within the track tensioning system.
Possible Causes

1. Clogged or Damaged Grease Fitting: Over time, grease fittings can become clogged with dirt or debris, preventing grease from entering the tensioning cylinder.
   
2. Failed Seals in the Tensioning Cylinder: The seals within the tensioning cylinder can wear out or become damaged, leading to grease leakage and loss of tension.
   
3. Corrosion or Rust on the Tensioning Rod: Exposure to moisture and dirt can cause rust to form on the tensioning rod, leading to sticking or failure to extend/retract properly.
   

Troubleshooting Steps
To address the issue of the track coming off with no grease flow:

1. Inspect the Grease Fitting: Check for any blockages or damage. If clogged, clean or replace the fitting.
   
2. Examine the Tensioning Cylinder: Look for signs of grease leakage around the cylinder seals. If seals are damaged, they may need to be replaced.
   
3. Check for Corrosion: Inspect the tensioning rod for rust or corrosion. If present, clean the rod and apply a rust inhibitor.
   
4. Test the Track Tension: After addressing the above issues, attempt to adjust the track tension by pumping grease into the fitting. Monitor for any resistance or unusual movement.
   

Preventive Maintenance Tips
To prevent future issues with the track tensioning system:

• Regularly Lubricate the System: Ensure the tensioning system is greased according to the manufacturer's recommendations.
  
• Keep Components Clean: Regularly clean the grease fittings and surrounding areas to prevent dirt and debris buildup.
  
• Inspect Seals and Rods: Periodically check the seals and rods for signs of wear or damage and replace as necessary.
  

Conclusion
The issue of the track coming off with no grease flow in the Takeuchi TB135 is often related to problems within the track tensioning system. By systematically troubleshooting and addressing potential causes such as clogged grease fittings, failed seals, or corrosion, operators can restore proper track tension and prevent further issues. Regular maintenance and vigilance are key to ensuring the longevity and reliability of the TB135's undercarriage components.
