Introduction to the Hitachi UHO83LC Excavator
The Hitachi UHO83LC is a robust and versatile hydraulic excavator known for its performance and reliability in a variety of construction and mining applications. One of the critical components that ensures the smooth operation of this machine is the track adjuster. A properly functioning track adjuster is essential for maintaining track tension and extending the lifespan of the tracks. When issues arise with the track adjuster, it can lead to track misalignment, excessive wear, and operational inefficiencies. This article discusses common track adjuster issues, how to troubleshoot them, and the necessary maintenance procedures for the Hitachi UHO83LC.
Function of the Track Adjuster
The track adjuster plays a vital role in maintaining proper track tension. It is a hydraulic or mechanical system used to adjust the length of the track, keeping it tight enough to prevent the track from slipping but not too tight to cause excess wear. The track adjuster compensates for wear in the track links and ensures that the tracks remain in optimal condition for smooth operation.
Common Issues with the Track Adjuster
If troubleshooting the track adjuster system reveals more complex issues, such as damaged hydraulic lines, broken track components, or deep internal damage to the adjuster mechanism, seeking professional help is advisable. Certified technicians can perform advanced diagnostics and repairs, helping to ensure that the system is restored to optimal working condition. Additionally, if you are unsure about the proper adjustment techniques or if you lack the necessary tools, a professional can perform the maintenance tasks more efficiently and safely.
Conclusion
The track adjuster on the Hitachi UHO83LC is a critical component for maintaining proper track tension and ensuring smooth, efficient operation. Regular maintenance and inspections can prevent many common issues, such as loss of tension, misalignment, or hydraulic leaks. By addressing these issues promptly and performing routine maintenance, operators can extend the lifespan of the tracks and avoid costly repairs. With proper care, the track adjuster system will continue to contribute to the overall performance and reliability of the Hitachi UHO83LC excavator.

Common Issues with the Track Adjuster
- Loss of Track Tension
- Symptoms: One of the most common issues with a track adjuster is a loss of track tension. When the track becomes too loose, it can cause the machine to lose traction, resulting in poor performance and potential damage to the undercarriage components.
- Possible Causes: Loss of track tension can occur due to leaking hydraulic seals, damaged adjuster pistons, or issues with the track adjuster spring. Additionally, worn or damaged track components can also contribute to a decrease in tension.
- Solutions: Inspect the hydraulic system for leaks around the track adjuster. If a hydraulic leak is present, replace the seals or gaskets. Check the adjuster piston and verify that it is functioning properly. If the track components are excessively worn, replacing them might be necessary to restore proper tension.
- Symptoms: One of the most common issues with a track adjuster is a loss of track tension. When the track becomes too loose, it can cause the machine to lose traction, resulting in poor performance and potential damage to the undercarriage components.
- Track Tightening Issues
- Symptoms: If the track is too tight, it can cause premature wear on the undercarriage and tracks, increase fuel consumption, and place unnecessary strain on the engine.
- Possible Causes: A faulty track adjuster or improper adjustments could be the cause of excessive tension. This can happen if the adjuster piston is stuck or if there’s an issue with the track adjuster valve.
- Solutions: Check for proper operation of the track adjuster and its components. If the adjuster is stuck or damaged, it will need to be repaired or replaced. If the valve is faulty, replacing it or ensuring it is correctly adjusted can resolve the issue.
- Symptoms: If the track is too tight, it can cause premature wear on the undercarriage and tracks, increase fuel consumption, and place unnecessary strain on the engine.
- Track Misalignment
- Symptoms: When the track adjuster is not functioning correctly, the track may become misaligned, causing uneven wear and potential damage to the track links and rollers.
- Possible Causes: Track misalignment can be caused by improper track tension, worn-out track links, or a malfunctioning track adjuster. In some cases, a bent or broken track frame can also cause alignment issues.
- Solutions: Inspect the entire track system for signs of damage or wear. Adjust the track tension to ensure it is within the recommended range. If the track frame is bent or damaged, repairs will be necessary to prevent further issues.
- Symptoms: When the track adjuster is not functioning correctly, the track may become misaligned, causing uneven wear and potential damage to the track links and rollers.
- Hydraulic Seal Leaks
- Symptoms: Hydraulic seal leaks around the track adjuster are another common issue. Leaking seals can cause the track adjuster to lose pressure, affecting its ability to maintain proper track tension.
- Possible Causes: Over time, hydraulic seals can wear out due to exposure to dirt, debris, and harsh operating conditions.
- Solutions: Inspect the hydraulic seals for any visible signs of damage or wear. If a leak is detected, replace the seals with OEM parts. Regularly check for leaks and ensure the hydraulic system is properly maintained to prevent seal failure.
- Symptoms: Hydraulic seal leaks around the track adjuster are another common issue. Leaking seals can cause the track adjuster to lose pressure, affecting its ability to maintain proper track tension.
- Routine Inspections
- Importance: Regular inspections of the track adjuster system are crucial to ensuring optimal performance. Look for signs of hydraulic leaks, excessive track wear, or improper tension during routine maintenance checks.
- Steps:
- Check the track tension regularly.
- Inspect the adjuster for leaks or signs of wear.
- Ensure that the track links are properly aligned and not excessively worn.
