Replacing the track chains on the Hitachi EX200LC is a challenging task that requires patience and the right tools. Here's a detailed breakdown of the steps involved:
1. Prepare the Equipment and Workspace
Before starting the replacement process, ensure that the excavator is safely parked on a flat, stable surface. Properly position the machine so that it is easily accessible for the track replacement process. Here's what you need to do:
Once the machine is safely lifted, the next step is to remove the old track chains. This process involves disconnecting the track’s master link and any other connecting parts.
While you have the tracks removed, this is an ideal opportunity to inspect other components of the undercarriage, including:
With the old chains removed and components inspected, it’s time to install the new track chains. Here's how:
After installation, lower the machine back to the ground and conduct a thorough test. Drive the machine forward and backward to ensure the new tracks are properly aligned and that there is no excessive noise or slippage. During the test, pay attention to the following:
After running the machine for a short time, check the tracks again for any signs of looseness or other issues. Ensure that the new tracks are functioning properly and that there is no abnormal wear. It’s a good idea to check the tracks after several hours of use to ensure that everything is working correctly.
Best Practices for Track Chain Maintenance
Maintaining the track chains on your Hitachi EX200LC is essential to prolonging their life and ensuring that the machine continues to perform optimally. Here are some best practices for ongoing track maintenance:
Replacing the track chains on the Hitachi EX200LC can be a time-consuming process, but it’s a necessary task to maintain the performance and safety of the machine. By following the proper steps and using high-quality replacement parts, you can ensure that your excavator continues to function smoothly for years to come.
Regular maintenance, timely replacements, and thorough inspections are key to extending the life of your track chains and other undercarriage components. With the right approach, the Hitachi EX200LC can continue to serve your heavy-duty excavation needs efficiently and reliably.

Signs That It’s Time to Replace Track Chains
Before diving into the process of replacing track chains, it’s important to understand when the chains need replacement. Here are a few common signs that indicate the track chains on your Hitachi EX200LC need attention:
- Excessive Track Wear: Over time, the track chains will show signs of wear such as visible cracks, elongated pin holes, and thinning of the track plates.
- Loose Tracks: If the tracks have become loose and there is too much slack in the chain, it might be a sign that the track chain has worn out.
- Track Noise or Vibration: Unusual noises, such as squeaking or clanking, or vibrations while operating the machine may indicate that the track chain is no longer functioning smoothly.
- Frequent Track Failures: If track failures are becoming a more frequent occurrence, replacing the track chain may be the best course of action to prevent more severe damage.
Replacing the track chains on the Hitachi EX200LC is a challenging task that requires patience and the right tools. Here's a detailed breakdown of the steps involved:
1. Prepare the Equipment and Workspace
Before starting the replacement process, ensure that the excavator is safely parked on a flat, stable surface. Properly position the machine so that it is easily accessible for the track replacement process. Here's what you need to do:
- Lift the excavator: Use the excavator’s hydraulic system to lift the machine off the ground, giving you enough clearance to access the track assembly.
- Support the machine: Place sturdy blocks or a jack to securely support the machine.
- Remove any debris from the tracks and surrounding area to create a clean working environment.
Once the machine is safely lifted, the next step is to remove the old track chains. This process involves disconnecting the track’s master link and any other connecting parts.
- Locate the master link: The master link is the key connection point between the two ends of the track. It will need to be carefully removed to free the chain from the rest of the system.
- Loosen the tension: Before removing the track chains, reduce the tension in the track by adjusting the tensioner or track adjuster. This will help ease the removal process.
- Use a track pin press: If the track chains are severely worn, you may need to use a track pin press to safely remove the pins connecting the track to the track shoes. Be sure to follow the manufacturer’s guidelines for removing these pins.
While you have the tracks removed, this is an ideal opportunity to inspect other components of the undercarriage, including:
- Track rollers: Inspect the track rollers for any signs of wear or damage. If any of the rollers are worn out or damaged, replace them at this time to ensure smooth operation in the future.
- Sprockets: Check the sprockets for wear. Worn-out sprockets can lead to improper tracking and cause issues when the new track chains are installed.
With the old chains removed and components inspected, it’s time to install the new track chains. Here's how:
- Align the new track chains: Carefully position the new chains so that they are aligned with the track system. Make sure the master link is oriented correctly to avoid installation errors.
- Connect the master link: Using the proper tools, insert the pins into the master link and connect the two ends of the track chain. You may need a track pin press to help ensure that the pins are securely fastened.
- Tighten the track: Once the track is in place, use the track tensioner to adjust the tension. The correct track tension is crucial for the smooth operation of the machine, and over-tightening or under-tightening can lead to premature wear or damage.
After installation, lower the machine back to the ground and conduct a thorough test. Drive the machine forward and backward to ensure the new tracks are properly aligned and that there is no excessive noise or slippage. During the test, pay attention to the following:
- Track alignment: The tracks should run smoothly without any signs of misalignment.
- Tension: Make sure the track tension is correct. If the tracks are too loose or too tight, adjust accordingly.
After running the machine for a short time, check the tracks again for any signs of looseness or other issues. Ensure that the new tracks are functioning properly and that there is no abnormal wear. It’s a good idea to check the tracks after several hours of use to ensure that everything is working correctly.
Best Practices for Track Chain Maintenance
Maintaining the track chains on your Hitachi EX200LC is essential to prolonging their life and ensuring that the machine continues to perform optimally. Here are some best practices for ongoing track maintenance:
- Regularly inspect track tension: Track tension should be checked regularly. Too much tension can wear out the undercarriage components quickly, while too little can cause the tracks to slip.
- Keep tracks clean: Clean the tracks frequently to remove dirt and debris that can lead to wear and tear. Consider using high-pressure washing systems to clean the tracks and undercarriage.
- Monitor track wear: Periodically check for track elongation or signs of wear and replace components as necessary to prevent costly repairs in the future.
Replacing the track chains on the Hitachi EX200LC can be a time-consuming process, but it’s a necessary task to maintain the performance and safety of the machine. By following the proper steps and using high-quality replacement parts, you can ensure that your excavator continues to function smoothly for years to come.
Regular maintenance, timely replacements, and thorough inspections are key to extending the life of your track chains and other undercarriage components. With the right approach, the Hitachi EX200LC can continue to serve your heavy-duty excavation needs efficiently and reliably.
