Track Adjustment for CAT 953 Track Loader

[MikePhua]

The CAT 953 track loader is a powerful, versatile machine used in a wide range of construction and earthmoving applications. However, like any heavy equipment, maintaining optimal performance requires regular maintenance, including proper track adjustment. This guide will explore the importance of track adjustments, common issues, and the steps involved in ensuring your CAT 953 runs smoothly.
Why Track Adjustment Matters
Tracks are a critical component of a track loader's mobility. They not only support the weight of the machine but also provide traction on challenging terrains. Over time, track tension can either loosen or tighten, leading to a range of issues, including:

• Excessive wear on the track links, sprockets, and rollers.
  
• Reduced machine efficiency, especially when operating on uneven ground.
  
• Increased fuel consumption due to inefficient movement.
  
• Damage to the undercarriage from improper tension, leading to costly repairs.
  

Proper track tension helps extend the lifespan of the entire track system and ensures smooth operation.
How to Check and Adjust Track Tension
Adjusting the track tension on the CAT 953 requires attention to detail and a few key tools. Here’s a step-by-step guide to making the necessary adjustments:

1. Inspect the Tracks
   Before making any adjustments, visually inspect the tracks for damage or wear. Check the track links, rollers, and sprockets for signs of irregular wear. If you notice excessive wear, it may be time to replace worn parts.
   
2. Check the Track Tension
   Use a track gauge to measure the tension. The ideal track tension for a CAT 953 is typically around 1-2 inches of deflection when a person applies pressure to the middle of the track. If the track is too tight or too loose, it will affect the machine’s performance and potentially cause further damage.
   
3. Locate the Tensioning Mechanism
   The CAT 953 features a tensioning system that can be adjusted via a grease fitting on the track adjuster. This system uses hydraulic pressure to adjust the track’s tension.
   
4. Adjust the Track Tension
   • To loosen the track: Use the grease gun to release pressure from the tensioning cylinder. This will allow the track to loosen.
     
   • To tighten the track: Pump grease into the tensioning cylinder to increase hydraulic pressure, which will tighten the track.
     
5. Recheck the Tension
   After adjusting, check the track tension again with a gauge to ensure it’s within the recommended range.
   
6. Test the Loader
   After the adjustment, test the machine under load to ensure the tracks are functioning properly. Pay attention to any unusual sounds or movements.
   

Common Problems with Track Adjustment

1. Track Over-tightening
   Over-tightening the track can put excessive strain on the undercarriage and reduce the lifespan of the tracks and other components. If the machine feels sluggish or the tracks show uneven wear, you might need to loosen the tension.
   
2. Track Slack
   If the track is too loose, it can cause the track to jump off the sprockets or cause excessive wear. Loose tracks also reduce the traction needed for efficient operation. If you notice that the track is slipping or not gripping the ground well, tightening the track is necessary.
   
3. Uneven Track Wear
   Uneven wear can indicate improper adjustment. If one side of the track wears faster than the other, you may need to inspect the alignment of the tracks and make sure they are properly tensioned.
   

Preventative Maintenance Tips
To keep your CAT 953 running efficiently and avoid frequent track adjustments, consider the following:

• Regular Track Inspections: Periodically check track tension and wear. Early detection of problems can prevent costly repairs.
  
• Proper Storage: When not in use, store the loader in a dry, sheltered area to reduce environmental damage to the track system.
  
• Routine Lubrication: Keep all components well-lubricated, especially the track adjuster mechanism, to prevent wear and ensure smooth operation.
  
• Replacement of Worn Components: Replace worn rollers, sprockets, and other undercarriage components at the first sign of excessive wear to maintain optimal performance.
  

Conclusion
Maintaining proper track tension on your CAT 953 is essential for ensuring its longevity, efficiency, and safety. By regularly checking and adjusting the track tension, you can minimize wear and tear on critical undercarriage components and maximize the performance of your loader. Regular maintenance not only helps prevent costly repairs but also improves fuel efficiency and productivity on the job site.
