• Compact Size: The loader is relatively compact, making it ideal for use in confined spaces or smaller job sites where larger equipment might struggle.
  

Common Issues with the International 125E Track Loader
Like any piece of machinery, the International 125E track loader may experience some issues over time, especially with heavy or constant use. Some of the most common issues reported by operators include:

1. Track Tension Problems
   Track tension is essential for optimal performance and longevity. If the tracks are too loose or too tight, they can wear out prematurely or cause the machine to lose traction.
   • Solution: Regularly check the track tension and adjust as needed. Use the manufacturer's specifications for correct track tension, and ensure the undercarriage is clean and free from debris.
     
2. Hydraulic Leaks
   Hydraulic leaks can be a major issue in any track loader, including the International 125E. Leaking hydraulic fluid can affect the overall performance of the loader, causing reduced lifting capacity and sluggish movement.
   • Solution: Inspect all hydraulic lines, hoses, and fittings regularly for leaks. If any parts are damaged or worn, replace them immediately to prevent further issues.
     
3. Engine Overheating
   Engine overheating is a common concern with heavy equipment, particularly during long hours of operation. The International 125E’s engine may overheat due to poor maintenance or external factors like clogged radiators.
   • Solution: Ensure the radiator is clean and free from dirt or debris that could restrict airflow. Regularly check coolant levels and ensure the engine’s cooling system is functioning properly.
     
4. Electrical Issues
   Electrical problems, such as malfunctioning alternators, batteries, or wiring issues, can prevent the track loader from starting or cause it to shut down unexpectedly.
   • Solution: Regularly inspect the electrical system for loose connections, corroded terminals, or damaged wiring. Check the battery and alternator to ensure they are functioning correctly.
     
5. Wear and Tear on Undercarriage
   The undercarriage, which includes the tracks, rollers, and sprockets, is one of the most critical components of a track loader. It’s exposed to constant wear, especially on rough terrain.
   • Solution: Inspect the undercarriage regularly for signs of wear or damage. Replace worn rollers, track shoes, or sprockets as needed to maintain smooth operation.
     

Routine Maintenance Practices
To ensure the longevity and efficiency of the International 125E track loader, regular maintenance is essential. The following practices should be part of a comprehensive maintenance schedule:

1. Engine Maintenance
   Regular engine maintenance is crucial for keeping the machine running smoothly. This includes:
   • Changing engine oil: Follow the manufacturer’s schedule for oil changes to ensure proper lubrication and cooling of engine parts.
     
   • Replacing air filters: Clean or replace air filters as needed to prevent dirt and debris from entering the engine.
     
   • Inspecting belts and hoses: Check belts and hoses for wear or damage, and replace them as necessary.
     
2. Hydraulic System Maintenance
   The hydraulic system is vital to the loader's functionality. Perform the following:
   • Check fluid levels: Regularly check and top up hydraulic fluid to maintain proper pressure and function.
     
   • Inspect filters: Clean or replace hydraulic filters to ensure proper fluid flow and prevent clogging.
     
3. Track and Undercarriage Maintenance
   The tracks and undercarriage are subject to heavy wear, so regular inspections are necessary:
   • Check track tension: Adjust track tension regularly to ensure smooth operation and prevent excessive wear.
     
   • Inspect rollers and sprockets: Look for any signs of wear or damage, and replace parts as necessary to maintain performance.
     
4. Electrical System Maintenance
   The electrical system should be checked periodically to avoid starting issues:
   • Test the battery: Ensure the battery is charged and in good condition.
     
   • Inspect wiring: Check for frayed or corroded wiring and make necessary repairs.
     
5. Cleaning and Debris Removal
   Regular cleaning is crucial for maintaining optimal performance:
   • Clean the loader: Remove dirt, mud, and debris from the machine after each use to prevent buildup that could interfere with its function.
     
   • Clean the radiator: Ensure the radiator is free from debris to prevent engine overheating.
     

Troubleshooting Tips

1. Troubleshooting Engine Overheating
   • If the engine overheats, check for radiator blockages or low coolant levels. Ensure that the cooling fan is working properly and that coolant is circulating effectively.
     
2. Dealing with Track Tension Problems
   • If the tracks are too tight or too loose, check for any misalignments or damaged parts. Adjust the tension as per the manufacturer’s guidelines, and replace any worn components.
     
3. Fixing Hydraulic System Leaks
   • If hydraulic fluid is leaking, locate the source of the leak and replace any damaged hoses or fittings. Ensure that the hydraulic fluid is topped up and that no air has entered the system.
     
4. Electrical Starting Issues
   • If the loader won’t start, test the battery and check for loose connections. If the alternator is not charging the battery, replace it or repair the electrical wiring as needed.
     

Conclusion
The International 125E track loader is a powerful and versatile machine that can handle a wide range of tasks. However, like any piece of heavy equipment, it requires regular maintenance and attention to ensure optimal performance. By following the outlined maintenance practices, addressing common issues early, and conducting routine inspections, operators can maximize the lifespan and efficiency of their International 125E track loader. Regular care and prompt troubleshooting are key to keeping this machine in peak working condition.
