CAT 259D Track Replacement

[MikePhua]

Replacing the tracks on a CAT 259D is an essential maintenance task that helps keep the machine running efficiently, especially for those working in tough, demanding environments. The CAT 259D, a popular compact track loader, is known for its versatility and ability to operate on a variety of surfaces, making it a favorite for construction, landscaping, and agricultural work. However, like all machines, the tracks will eventually wear out and need replacement. Understanding how to replace them and the key considerations involved is critical for operators to maintain machine performance and avoid costly repairs.
Understanding the CAT 259D and Its Track System
The CAT 259D is part of Caterpillar’s D-Series of compact track loaders. These machines are equipped with a hydrostatic drive system, which provides excellent traction and stability, especially in soft or uneven ground conditions. Unlike wheeled loaders, which struggle in muddy, sandy, or wet conditions, compact track loaders like the 259D excel due to their continuous rubber tracks, which offer superior flotation and stability.
Tracks on the CAT 259D, like all rubber tracks, are exposed to significant wear from constant friction, abrasion, and the weight of the machine. Over time, the rubber may crack, the steel components may stretch, and the tracks may become misaligned. Regular inspection and timely replacement of the tracks are essential for the smooth operation of the machine.
Signs that Tracks Need Replacement
It’s important to recognize when the tracks on your CAT 259D are due for replacement. Common signs that indicate worn-out tracks include:

• Excessive wear on the tread: The tread pattern on the track begins to wear down, leading to reduced traction and performance.
  
• Cracks or splits: Visible cracks in the rubber or splits in the track indicate that the rubber is deteriorating.
  
• Track misalignment: If the tracks are no longer running straight or are rubbing against the side of the machine, they might be stretched or damaged.
  
• Loss of track tension: Tracks that sag or feel loose during operation may need to be replaced or tightened.
  

Ignoring these signs can lead to costly damage to the undercarriage or drive system, further complicating repairs and leading to expensive downtime.
Track Replacement Process for the CAT 259D
Replacing the tracks on the CAT 259D involves several important steps. While it may seem like a straightforward task, it requires precision and the right tools to ensure the new tracks are properly installed and the system functions efficiently.
1. Preparation
Before starting the track replacement process, ensure you have the following tools and materials:

• Replacement tracks (OEM or equivalent)
  
• Wrenches and socket set
  
• Hydraulic jack or lifting equipment
  
• Track press or a similar tool to remove the tracks
  
• Grease for lubricating the track system
  

Make sure the area where you are working is clean and level. It’s essential to work on stable ground to prevent accidents when lifting the machine or removing the tracks.
2. Lifting the Machine
The first step in the process is lifting the CAT 259D off the ground to relieve the pressure on the tracks. This can be done using a hydraulic jack or a lifting device, depending on the equipment available. Ensure that the machine is stable and secure before moving on to the next step.
3. Removing the Old Tracks
Once the machine is elevated, it’s time to remove the old tracks. To do this, you will need to release the tension on the tracks. The CAT 259D features an adjustable tension system that allows you to loosen the tracks. Locate the tension adjustment bolts and use a wrench to loosen them. This will allow the tracks to become slack and easier to remove.
Next, use a track press or hydraulic equipment to remove the tracks from the undercarriage. Depending on the condition of the tracks and machine, this process may require some effort, especially if the tracks are severely worn or have been on the machine for an extended period.
4. Installing the New Tracks
Once the old tracks have been removed, it’s time to install the new ones. Begin by positioning the new tracks in place, ensuring they are aligned properly with the sprockets and idlers. The tracks should fit snugly but should not be too tight to avoid unnecessary wear.
Before tightening the tension, check that the tracks are running straight and that there are no obstructions or misalignments. Use the track tensioning system to adjust the track tightness. Proper tension is essential to prevent slipping or uneven wear.
5. Testing the Machine
After the tracks are installed and the tension is set correctly, lower the machine back to the ground. Start the CAT 259D and drive it forward to ensure the tracks are moving smoothly and evenly. Listen for any unusual noises or vibrations, which could indicate that the tracks are not installed properly or that there is an issue with the undercarriage.
If everything looks and sounds good, the machine is ready for work. Make sure to monitor the tracks during the first few hours of operation to ensure proper performance.
Track Maintenance Tips for Longevity
Replacing tracks on the CAT 259D is a significant investment, but with proper care and maintenance, you can extend the life of the new tracks and avoid frequent replacements. Here are a few tips to help maintain the tracks:

• Regular inspection: Periodically inspect the tracks for signs of wear, cracks, or misalignment. Catching problems early can help prevent costly repairs.
  
• Track tension: Ensure the track tension is correct. Over-tightening can lead to unnecessary wear, while too little tension can cause the tracks to slip or misalign.
  
• Proper storage: If you are storing the machine for an extended period, keep the tracks off the ground to avoid deformation.
  
• Use appropriate surfaces: Avoid using the machine on hard, abrasive surfaces when possible, as this will accelerate track wear.
  
• Lubrication: Regularly lubricate the track system to reduce friction and prevent damage to the undercarriage.
  

Conclusion
Replacing the tracks on the CAT 259D is a critical maintenance task that ensures optimal performance and prevents further damage to the undercarriage system. With the right tools and proper attention to detail, track replacement can be completed efficiently, extending the lifespan of your machine. By following the recommended maintenance practices, you can get the most out of your tracks and reduce the risk of costly downtime.
