Rubber Track Installation on CAT 277: A Step-by-Step Guide

[MikePhua]

Installing new rubber tracks on a CAT 277 or similar compact track loader can seem like a daunting task, but with the right tools and instructions, it is an achievable and straightforward process. Proper installation is crucial for ensuring that the tracks perform well and maintain their longevity. Rubber tracks are designed to offer better traction and lower ground pressure compared to steel tracks, which makes them ideal for use on soft or delicate surfaces.
This article provides a detailed guide on how to install rubber tracks on a CAT 277, covering necessary preparations, steps for installation, and maintenance tips to keep your tracks in top condition.
Understanding Rubber Tracks
Rubber tracks are an essential component of compact track loaders, offering several benefits, including:

• Reduced Ground Pressure: The wide surface area of rubber tracks helps to distribute the weight of the loader, which minimizes damage to soft surfaces like grass, dirt, and asphalt.
  
• Improved Traction: Rubber tracks provide excellent traction in various conditions, including mud, snow, and loose gravel.
  
• Durability and Comfort: Rubber tracks are more comfortable to operate on than steel tracks, offering a smoother ride. They also have a longer lifespan if properly maintained.
  

On the CAT 277, rubber tracks are commonly used for their versatility and ability to handle different types of terrain.
Tools and Materials Needed for Installation
Before starting the installation, ensure that you have all the necessary tools and materials:

• Replacement rubber tracks (specific to the CAT 277 model)
  
• Lift jack or jack stands
  
• Wrenches and socket set
  
• Torque wrench
  
• Pry bar or crowbar
  
• Lubricant (optional, for easier fitting)
  
• Safety gloves and eye protection
  

It’s also a good idea to have the owner’s manual for your CAT 277 on hand for specific instructions regarding torque settings and any other model-specific information.
Step-by-Step Guide to Installing Rubber Tracks on a CAT 277
Step 1: Prepare the Loader

1. Park the loader on a flat, stable surface: Make sure the ground is level to ensure safety and precision during the installation.
   
2. Lift the machine: Use a lift jack or jack stands to elevate the loader, allowing the tracks to be removed and replaced. Ensure that the loader is securely supported to prevent accidents.
   
3. Release the tension: Before removing the old tracks, you’ll need to release the tension on the track. This is typically done by loosening the tension bolt on the rear of the track frame. If your model has a grease tensioner, it will be necessary to release the grease to reduce the tension.
   

Step 2: Remove the Old Tracks

1. Loosen the track bolts: Using a wrench or socket set, carefully loosen the bolts securing the track assembly to the idlers and sprockets.
   
2. Remove the track: Once the bolts are loosened, use a pry bar or crowbar to carefully remove the track from the sprockets and idlers. Be cautious to avoid damaging the sprockets, idlers, or other components.
   
3. Inspect the components: With the old tracks removed, take the opportunity to inspect other components such as the rollers, sprockets, and idlers for wear. If any parts are damaged or worn, it’s a good time to replace them.
   

Step 3: Install the New Rubber Tracks

1. Align the track: Position the new rubber track on the ground in front of the loader’s track frame. Carefully align it with the sprockets, idlers, and rollers to ensure that it will fit properly when lifted into place.
   
2. Lift the track into position: Using a pry bar or lifting device, carefully lift the new track and place it around the sprockets and idlers. Ensure that the track is aligned with the frame and components.
   
3. Reattach the bolts: Once the track is properly positioned, reattach the bolts to secure the track to the loader’s undercarriage. Use a torque wrench to tighten the bolts to the manufacturer’s recommended torque settings.
   
4. Check the alignment: Once the track is secured, check that it is properly aligned with the frame and sprockets. The track should sit evenly around the undercarriage without any misalignment.
   

Step 4: Adjust Track Tension

1. Adjust the tension: After the track is installed, you will need to adjust the tension. Use the tensioning bolt (located at the rear of the track frame) to tighten or loosen the track. The correct track tension is important for proper operation and longevity.
   
2. Check the tension: The track should have a slight deflection when pressure is applied. If the track is too loose, it can slip off the sprockets, while if it’s too tight, it can cause excessive wear on the track and components.
   

Step 5: Final Checks

1. Test the machine: Lower the loader and operate it for a short period to ensure the tracks are running smoothly. Listen for any unusual noises and observe the tracks for proper alignment and tension.
   
2. Inspect after use: After a few hours of use, check the tracks again to ensure that they have settled properly and that the tension is still correct.
   

Troubleshooting Common Issues
Even after successful installation, there are a few common issues you might encounter with rubber tracks:

• Uneven Wear: This can occur if the track is not properly tensioned or aligned. Regularly check the track tension and alignment, and ensure that the undercarriage components are in good condition.
  
• Track Slippage: If the track slips off the sprockets during operation, it may be a sign that the track is too loose or the tension needs adjusting. Also, check for any debris that might be causing the track to slip.
  
• Cracking or Damage: If the rubber track develops cracks or tears, it could be due to excessive tension or rough operating conditions. Regularly inspect the track for any signs of wear and replace it as needed.
  

Maintenance Tips for Longer Track Life
To extend the life of your rubber tracks on the CAT 277, follow these maintenance tips:

• Regularly check the track tension to ensure that it is neither too tight nor too loose. Proper tension reduces wear and increases the lifespan of the track.
  
• Clean the tracks after use, especially if you’ve been working in muddy, wet, or abrasive conditions. Removing debris from the track will help prevent it from causing damage over time.
  
• Inspect the undercarriage components, including rollers, idlers, and sprockets. Worn-out parts can cause the track to misalign or wear unevenly.
  
• Store the loader properly: If the CAT 277 is not being used for an extended period, store it on flat ground and lift the tracks off the ground to prevent the tracks from becoming deformed.
  

Real-World Example: The Importance of Proper Installation
In a construction project in Arizona, a contractor working on a commercial site faced significant downtime due to a misaligned rubber track on a CAT 277. The track had been improperly installed, which caused it to wear unevenly and eventually slip off during operation. This resulted in costly repairs and lost productivity. After replacing the track and following proper installation and maintenance procedures, the machine operated smoothly for the remainder of the project, with no further issues.
Conclusion
Installing rubber tracks on a CAT 277 is a straightforward process that, when done correctly, can enhance the loader’s performance and longevity. By following the steps outlined above, including proper tensioning, alignment, and maintenance, you can ensure that your rubber tracks perform at their best. Proper installation and ongoing maintenance will not only prevent unnecessary repairs but also maximize your investment in your CAT 277 loader.
