Replacing Lower Bushings in Loader Arms on Takeuchi TL140: Steps and Considerations

[MikePhua]

The Takeuchi TL140 is a popular tracked skid steer loader known for its excellent performance and durability. However, over time, the lower bushings in the loader arms can wear out, leading to decreased performance and potential operational issues. This article provides a guide on how to replace the lower bushings in the loader arms of the Takeuchi TL140, helping users complete this repair efficiently.
1. Impact of Worn Bushings
The lower bushings in the loader arms play a crucial role in supporting and connecting the arms to the main body of the loader. When these bushings wear out, several problems can occur:

• Unstable Operation: Worn bushings can cause looseness in the connection between the loader arms and the machine, leading to instability during operation.
  
• Increased Repair Costs: If not replaced in time, severely worn bushings can cause damage to the loader arms or other critical components, resulting in higher repair costs.
  
• Reduced Efficiency: The performance of the machine, such as lifting capacity and operational speed, can be affected if the bushings are not functioning properly.
  

Therefore, regular inspection and replacement of worn bushings are essential to maintain the machine’s optimal performance.
2. Tools and Preparation
Replacing the bushings requires a set of tools and preparation to ensure a smooth process. Some common tools needed for the job include:

• Jack: Used to lift the machine and ensure safe operation during the repair.
  
• Prying Tool or Support Brackets: Used to stabilize the loader arms during the replacement process.
  
• Impact Wrench: For loosening bolts and removing parts.
  
• New Bushings: Ensure you have the correct bushings that match your machine model.
  
• Hydraulic Jack: A hydraulic jack may be necessary if some components are particularly heavy.
  

Before starting, ensure the loader is stable and that all necessary safety precautions are taken.
3. Steps to Replace the Lower Bushings
The following are the basic steps to replace the lower bushings in the loader arms of the Takeuchi TL140:

• Step 1: Lift the Machine
  Use a jack to lift the loader to an appropriate height, ensuring the loader arms are in a workable position. Stabilize the machine with support brackets and ensure the wheels are secured to prevent any tipping.
  
• Step 2: Remove Connecting Parts
  Use the impact wrench to remove the bolts and connecting parts securing the bushings. In some cases, a prying tool can help loosen stuck parts. If the loader arms or other components are heavy, use a hydraulic jack to provide extra support.
  
• Step 3: Remove the Old Bushings
  After all the connections have been removed, carefully take out the worn bushings. If the bushings are stuck, use impact tools or prying tools to assist with removal.
  
• Step 4: Install New Bushings
  Apply lubricating oil to the new bushings to ease the installation process. Insert the new bushings into the correct position and ensure they fit snugly. Reinstall the removed parts and tighten the bolts securely with the impact wrench.
  
• Step 5: Inspection and Testing
  After the installation, check the movement of the loader arms to ensure everything is properly aligned. Perform a brief operational test to ensure the machine is functioning smoothly with no unusual behavior.
  

4. Common Issues and Solutions
During the process of replacing the bushings, there may be some common issues. Here are solutions to help troubleshoot these problems:

• Bushings Not Aligning Properly
  If the bushings do not align, check that you have the correct bushings and confirm they are installed in the proper orientation. Use a prying tool to gently adjust the position if needed.
  
• Difficulty Removing Bolts
  If bolts are rusted or stuck, apply lubricants or heat to loosen them. Be sure to use the right tools to avoid damaging the bolt heads during removal.
  
• Loose Bushings After Installation
  If the new bushings become loose after installation, verify that all components are correctly aligned and the bolts are tightened to the proper torque specifications. Re-tighten the bolts if necessary.
  

5. Conclusion
Replacing the lower bushings in the loader arms of the Takeuchi TL140 is a straightforward repair task but requires attention to detail and the right tools. By regularly inspecting and replacing worn bushings, operators can ensure the loader continues to perform at its best, reducing the risk of further damage and costly repairs. If you lack the experience or tools to perform this task, it may be best to seek professional help to ensure proper installation.
