CAT 953 Track Rod Extender Overview

[MikePhua]

Introduction
The CAT 953 is a versatile and powerful crawler loader designed for heavy-duty applications. One of the key components of its design is the track rod, which plays a crucial role in the loader's overall performance and mobility. When the track rod experiences wear or other issues, an extender can be used to resolve some operational challenges. This article provides an overview of the track rod extender for the CAT 953, including its purpose, installation process, and maintenance considerations.
Purpose of the Track Rod Extender
The track rod extender is designed to extend the reach and adjust the functionality of the track assembly on the CAT 953 crawler loader. This extension is often used when the existing track rods have become worn or are no longer providing the necessary support for the loader's operation. The extender allows for better track tension, improves the stability of the machine, and ensures smooth movement across uneven terrain.
Why Use a Track Rod Extender?
A track rod extender is useful for several reasons:

• Track Wear: Over time, track rods may become worn due to continuous use in rough conditions. The extender allows for better adjustment and ensures the track remains properly tensioned.
  
• Improved Stability: Adding an extender can help restore the track assembly’s balance, preventing uneven wear and reducing the likelihood of mechanical failure.
  
• Cost-Effective Solution: Rather than replacing the entire track assembly or other components, using a track rod extender can be a more cost-effective way to address issues with the track’s performance.
  
• Versatility: The track rod extender is a versatile solution that can be adjusted to fit different configurations based on the operating conditions and requirements of the job.
  

Installing the Track Rod Extender
Installing a track rod extender on the CAT 953 requires careful attention to detail and following the manufacturer’s guidelines to ensure proper functionality. Below is an overview of the general installation steps:

1. Preparation:
   • Safety: Always follow safety protocols when working with heavy machinery. Ensure that the loader is turned off, the parking brake is engaged, and any necessary safety gear is worn.
     
   • Tools: Ensure that the correct tools, such as wrenches, lifting equipment, and the track rod extender kit, are available.
     
2. Track Removal:
   • Begin by lifting the tracks off the ground to reduce tension.
     
   • Use the appropriate lifting equipment to safely remove the tracks from the track assembly.
     
3. Removing the Existing Track Rod:
   • Remove the existing track rod by loosening the bolts that connect it to the track assembly.
     
   • Depending on the condition, some force may be required to dislodge the rod, particularly if it has been in place for a long time.
     
4. Attaching the Track Rod Extender:
   • Position the extender in place and align it with the track assembly.
     
   • Secure the extender to the track rod using bolts or pins, as per the manufacturer’s instructions. Ensure that the extender is tightly secured to avoid movement during operation.
     
5. Reinstalling the Track:
   • Once the extender is in place, reinstall the track onto the loader. Ensure that the track is correctly aligned and fits snugly around the track assembly.
     
6. Tension Adjustment:
   • After installation, adjust the track tension as necessary. This step is crucial to ensure that the track runs smoothly without any slippage or strain on the machine.
     

Maintenance Considerations
Proper maintenance is essential for ensuring the longevity and effectiveness of the track rod extender. Here are some maintenance tips to keep in mind:

• Regular Inspections: Check the track rod extender regularly for signs of wear, corrosion, or damage. Ensure that all fasteners remain tight, and there is no movement between the extender and the track rod.
  
• Lubrication: Regularly lubricate the track assembly to reduce friction and wear. Proper lubrication helps keep the track running smoothly and prevents unnecessary wear on both the extender and the tracks.
  
• Track Tension: Periodically check the track tension to ensure it is within the recommended range. Improper track tension can lead to excessive wear and may even cause damage to the track rod extender.
  
• Replace Worn Parts: If the track rod extender shows signs of excessive wear or damage, replace it as soon as possible to avoid affecting the loader’s performance.
  

Common Issues and Troubleshooting
Here are some common issues that may arise with the track rod extender on the CAT 953:

• Uneven Wear: If the track rod extender does not function properly, it may result in uneven wear on the tracks. This can be caused by improper installation or misalignment of the extender. Ensure that the extender is correctly aligned and securely fastened to prevent this issue.
  
• Loose Track Rod: Over time, the track rod may become loose, causing instability in the machine. Check for loose bolts or fasteners and tighten them as necessary.
  
• Track Slippage: Track slippage can occur if the track rod extender is not properly tensioned. Regularly check the track tension and make adjustments if necessary.
  

Conclusion
The track rod extender for the CAT 953 is a vital component that helps maintain the stability and efficiency of the machine. By ensuring the extender is properly installed and regularly maintained, operators can avoid costly repairs and enhance the performance of the crawler loader. Whether addressing worn track rods, improving stability, or simply ensuring smooth operation, the track rod extender is a practical solution for maintaining the CAT 953 in top condition. Always refer to the manufacturer’s guidelines for installation and maintenance to ensure optimal performance and longevity.
