Best Way to Remove Old Pads from Chains: A Step-by-Step Guide

[MikePhua]

Introduction: The Importance of Proper Pad Removal on Heavy Equipment
When it comes to maintaining heavy equipment, especially machines like excavators, bulldozers, and skid steers, the wear and tear on the chains and tracks is a common concern. Track pads, which are affixed to the chains, play a crucial role in providing traction and protecting the tracks from excessive wear. However, as these pads age and wear out, they need to be replaced to ensure optimal performance and to prevent further damage to the undercarriage.
Removing old track pads from chains can be a challenging and time-consuming task. Improper removal can result in damage to the chains or other components, potentially leading to costly repairs. This guide will walk you through the best methods for removing old pads from chains, offering useful tips to make the job easier and more efficient.
Tools and Materials Needed
Before starting the removal process, it's important to gather the proper tools and materials to ensure that the job is done safely and effectively. Here is a list of essential tools for this task:

• Hydraulic Jack (for lifting the equipment)
  
• Wrench Set (preferably impact wrenches for faster removal)
  
• Socket Set
  
• Pry Bar or Track Pad Puller (to help with stubborn pads)
  
• Hammer (for tapping and loosening)
  
• Lifting Straps (for safely handling the pads)
  
• Replacement Track Pads (if you're installing new ones)
  
• Safety Gear (gloves, goggles, etc.)
  

Having the right tools at your disposal will ensure a smooth process and reduce the chances of injury or damage to the equipment.
Step 1: Prepare the Equipment
Before you start removing the pads, you must ensure that the equipment is in a safe and stable position.

1. Lift the Equipment: Use a hydraulic jack or a lift to raise the vehicle off the ground. Make sure the vehicle is secure and stable before you proceed with the pad removal.
   
2. Secure the Track: If necessary, use lifting straps to hold the track in place. This prevents the track from moving while you're working.
   
3. Remove any Obstructions: Clear the work area of any loose dirt or debris that could obstruct the process. Ensuring a clean workspace helps to maintain safety and efficiency.
   

Step 2: Loosen the Bolts and Pins
Most track pads are held in place by bolts or pins that connect them to the track assembly. These can sometimes be difficult to remove if they are rusted or have been in place for a long time.

1. Loosen the Bolts: Use a wrench or impact wrench to loosen and remove the bolts securing the pads to the chains. It's essential to apply steady pressure to avoid stripping the bolts.
   
2. Use a Hammer if Needed: If the bolts or pins are particularly stubborn, a hammer can be used to tap them gently in the counterclockwise direction. Make sure not to hit the bolts too hard, as this could damage the threads.
   
3. Check for Any Additional Fasteners: In some cases, the track pads may be secured with additional fasteners. Inspect the pad carefully to make sure all fasteners are removed.
   

Step 3: Remove the Track Pads
Once the bolts and pins are loosened or removed, it's time to remove the track pads.

1. Use a Pry Bar or Track Pad Puller: If the track pad is stuck or difficult to remove, use a pry bar or a track pad puller. Insert the pry bar between the pad and the chain and apply leverage gently to lift the pad.
   
2. Avoid Forceful Pulling: Never yank or force the pad off. If the pad is resistant to removal, check for any remaining fasteners or obstructions. Forcing it could damage the chain, resulting in costly repairs.
   
3. Lift the Pads Away: Once the pad is loosened, carefully lift it off the track and set it aside. If you’re replacing the pads, have the new ones ready to be installed.
   

Step 4: Inspect the Chains and Underbelly
After removing the old pads, take this opportunity to inspect the chains and other components of the undercarriage.

1. Check for Wear and Tear: Look for any signs of wear or damage on the chains, rollers, or sprockets. If there’s significant damage, you might need to replace these parts to avoid further complications.
   
2. Clean the Tracks: While the pads are off, it's a good time to clean the tracks and surrounding areas. Use a pressure washer or scrub brush to remove any accumulated dirt, grime, or debris. Cleaning helps prevent buildup that could affect the performance of the track assembly.
   
3. Lubricate Components: If you see any signs of rust or friction, applying lubricant to the chains or rollers can help prevent further damage and improve overall performance.
   

Step 5: Install the New Track Pads
With the old pads removed and the chains inspected and cleaned, you’re now ready to install the new pads.

1. Align the New Pads: Carefully position the new track pads onto the chains, making sure the bolt holes line up properly. Some tracks may require you to lift the track slightly to align the pads correctly.
   
2. Secure the Pads: Insert the bolts or pins through the holes and tighten them securely. Use a torque wrench to ensure the bolts are tightened to the correct specification.
   
3. Double-Check the Installation: Once all the bolts are tightened, give the pads a slight wiggle to make sure they are secure. Check that the pads are aligned properly and that no fasteners are loose.
   

Step 6: Lower the Equipment and Test
Once the new pads are installed, it's time to lower the equipment back onto the ground.

1. Lower the Vehicle: Carefully use the hydraulic jack or lift to lower the equipment back to the ground. Ensure the equipment is stable before proceeding with the final tests.
   
2. Test the Tracks: Start the vehicle and drive it forward slowly to check that the new pads are properly aligned and functioning. Listen for any unusual sounds and observe the movement of the tracks to make sure everything is operating smoothly.
   

Common Mistakes to Avoid

1. Not Using the Correct Tools: Attempting to remove the pads without the proper tools can lead to mistakes or damage. Using an impact wrench, for example, can speed up the process but could also strip bolts if not used correctly. Always use the appropriate tool for each job.
   
2. Rushing the Process: Taking your time during the pad removal and installation process ensures that you don’t overlook any critical components, like fasteners or alignment issues.
   
3. Neglecting Safety: Always wear appropriate safety gear, including gloves and goggles, to protect yourself from flying debris or accidents during the pad removal process.
   

Conclusion: Keeping Your Equipment in Top Shape
Proper maintenance of track pads is critical for the longevity of your equipment. Regularly replacing old pads ensures that the machine continues to operate at peak efficiency, reducing wear on the undercarriage and improving overall safety and performance. Whether you're a professional in the construction industry or managing your own fleet, understanding the best methods for removing old pads and installing new ones will save you time, money, and hassle in the long run.
