175C Track Tension Adjustment Help

[MikePhua]

Track tension is a crucial maintenance aspect for excavators and other heavy equipment. Incorrectly tightened tracks, whether too loose or too tight, can negatively affect the equipment's performance, cause premature wear, and even shorten the machine's lifespan. This article will guide you through the process of adjusting the track tension on a 175C excavator and provide solutions to common track tension issues.
Importance of Track Tension
The track tension system ensures that the tracks maintain the correct tension during operation. If the tracks are too loose, they may slip off or wear excessively, reducing efficiency and safety. Conversely, if the tracks are too tight, it can increase the strain on the drive motor, leading to unnecessary energy consumption and accelerated wear of mechanical components. Therefore, ensuring that the track tension system is properly adjusted is vital for the longevity and optimal performance of the equipment.
How to Check Track Tension
Checking the track tension is straightforward and can be done in the following ways:

1. Check the Track Tightness by Hand
   Manually feel the track to assess its tightness. If there is noticeable slack or if the track is not centered, the tension may be insufficient.
   
2. Use a Track Tension Tool
   Use specialized tools (such as a track tension gauge) to measure the track tension. These tools typically provide a standard tension value to ensure the track is within the ideal range.
   
3. Inspect for Track Wear
   Over-tightened or over-loosened tracks can lead to uneven wear. Inspect the track for signs of abnormal wear to determine whether track tension adjustments are needed.
   

How to Adjust Track Tension

1. Inspect the Tensioning Device
   On the 175C excavator, the track tensioning device is typically located at the rear of the track. Check the tensioning device for any signs of damage or malfunction. Ensure that there are no worn-out components and that the device is functioning properly.
   
2. Adjust the Hydraulic System
   Track tension on the 175C is generally controlled by a hydraulic system. By adjusting the hydraulic pump or the pressure settings, you can either increase or decrease the track tension. Make the necessary adjustments to maintain proper tension.
   
3. Adjust the Track Tension
   Use the appropriate tools to adjust the tensioning bolts to the correct tightness. After adjusting, double-check the track's tightness to ensure it's within the recommended range.
   
4. Check Hydraulic Oil and Lines
   While making adjustments, verify the hydraulic oil level and ensure that there are no leaks in the hydraulic lines. Insufficient hydraulic oil or a leaking line can lead to inadequate track tension.
   

Common Issues and Solutions

1. Loose Tracks
   • Cause: This could be due to insufficient hydraulic pressure or a malfunctioning track tensioning device.
     
   • Solution: Check the hydraulic system and adjust the pressure. If the tensioning device is faulty, replace the necessary parts.
     
2. Over-tightened Tracks
   • Cause: This could result from excessive adjustment in the hydraulic system, causing the track to become too tight.
     
   • Solution: Reduce the hydraulic pressure and recheck the track tension to bring it back to normal levels.
     
3. Leaking Tensioning Device
   • Cause: A leak in the hydraulic system could lead to insufficient track tension.
     
   • Solution: Inspect the hydraulic lines for damage or wear. If any leaks are found, replace the damaged components immediately.
     

Conclusion
Track tension is a critical factor in ensuring the smooth operation of the 175C excavator. Regularly checking and adjusting the track tension will help prevent excessive wear on the tracks and other machine components, ultimately extending the equipment’s lifespan. For users who frequently operate heavy machinery, understanding how to properly adjust track tension can significantly improve work efficiency and reduce maintenance costs.
