Track excavators are important parts of heavy equipment in excavation and building tasks. They largely rely on their tracks to move over different types of terrains effectively. However, over time, these tracks may deteriorate or sustain damage. A track excavator track replacement and repair ability are useful one that can save time and money. The entire process of track replacement and repair is the topic of discussion in this article.

Identifying the Damage

Before starting any replacement and repair job, it is necessary to carefully evaluate the extent of the damage to your excavator’s tracks. You should start the process by looking for damage on both tracks visually. Do not forget to take a look at the rubber or metal parts for signs of wear, tears, cuts, or other obvious damage. Track tension and alignment should be closely monitored since improperly aligned tracks can result in excessive wear and poor performance.

It is better to operate the excavator while keeping an ear out for any odd vibrations, sounds, or track slippage. You may also need to check to see if the excavator pulls to one side as well, as this could be a sign of track-related problems. On the other hand, using the service handbook for the excavator as a guide, measure the track tension. Make sure the tension on both tracks is appropriate for optimum performance.

Getting the Required Equipment and Materials

After evaluating the damage, gather the equipment and supplies needed for the repair. Some special types of tools and materials may be necessary for the repairing process of tracks in your used track excavator for sale.


  • A socket set and wrenches are necessary to remove and replace bolts and nuts.
  • A hydraulic jack or other lifting apparatus to raise the excavator.
  • Hammers and pry bars for taking apart and reassembling components.
  • A torque wrench to make sure that bolts and nuts are tightened according to the right guidelines.
  • A track press or track chain assembly tool for operating on the tracks safely.


  • New tracks that adhere to your excavator’s standards.
  • Grease and oil are lubricants to keep parts properly lubricated.
  • Extra track bolts and nuts in case any need to be replaced.
  • PPE such as gloves, safety glasses, and hearing protection for your protection.

Safety Measures

Your primary focus during any repair work should always be safety. Here are some things to remember regarding safety:

  • Place the excavator in a level, secure location.
  • Turn off the engine after using the parking brake.
  • Use strong chocks to block the tracks to stop any unintentional movement.
  • Wear the proper PPE, such as gloves, safety glasses, and earplugs.
  • If you must operate in a dusty environment, try wearing a dust mask or working in a well-ventilated space.

Taking out the faulty tracks

You must take the damaged tracks out of the excavator before you can repair them. This is how you do it:

  • To lessen the strain on the damaged track, start by releasing the track’s tension. For further instructions on how to do this correctly, consult the service handbook for your excavator. 
  • After that lift the excavator using a hydraulic jack or other lifting apparatus to create adequate room to securely remove the tracks. 
  • You need to use the proper wrenches to locate the track tension bolts and remove them. 
  • Release the tension and carefully detach the track from the driving sprocket and the front idler. 
  • At last, get the excavator out from under the damaged track by sliding it.

Getting Ready for a Track Replacement

It is time to get ready for the replacement now that the damaged track has been removed. Follow the process to carry out this step:

  • Clean the track frame, idler, and sprocket completely.
  • Check these parts for any indications of wear or damage. If required, swap them out.
  • To guarantee smooth functioning during the track replacement, lubricate the track frame, idler, and sprocket as needed.
  • Check the new tracks for damage or flaws before installing them. To prevent issues later in the process, it is imperative to complete this step.

Replacement Tracks’ Installation

Now it is time to install new tracks on adding the replacement tracks:

  • Make that the idler and sprocket are properly positioned in relation to the replacement tracks. 
  • Slide the track into place slowly and cautiously, making sure it connects with the sprocket teeth.
  • Following the instructions provided by the manufacturer for your particular excavator model, gradually increase the track tension.
  • Make sure that the track tension bolts are adjusted to the specified specifications using a torque wrench.
  • Make sure all bolts and nuts on the track assembly are secure by checking and tightening them. 

Testing and Modification

It is a must to test the new tracks after installation and make any necessary corrections. 

  • Check to make sure the track tension is set properly on both sides for continued movement. Optimal performance and longevity are guaranteed by proper track tension.
  • Start the excavator and check how it works. 
  • Pay close attention to odd vibrations and sounds. Make sure the excavator moves without pulling to one side and travels smoothly.
  • Adjust the track tension as necessary until the excavator performs at its best. Your excavator will be prepared for the task at hand after some fine-tuning.

Regular Maintenance

Maintaining your excavator’s tracks on a regular basis is another important step for extending its lifespan.

  • Clear the tracks for any dirt or debris on a regular basis. The tracks will last longer if they are kept clean.
  • Check the tracks periodically for wear, cuts, or other damage. Further issues can be avoided by early detection and prompt replacement of damaged tracks.
  • At certain intervals, check and adjust the track tension in accordance with the manufacturer’s recommendations. The tracks on your excavator can operate at peak efficiency for many years with routine maintenance.


Your track excavator’s tracks need to be properly maintained and repaired if you want to preserve its dependability and performance. You can examine, replace, and repair damaged tracks with confidence by following the instructions provided in this book and putting safety first, which will help you save time and money. Always refer to the service handbook for your excavator for detailed instructions and recommendations. You can maintain your track excavator in peak functioning condition for many years with the appropriate information and equipment.
