Understanding T190 Tracks: Maintenance, Issues, and Best Practices

[MikePhua]

Introduction
The Bobcat T190, a popular compact track loader, is widely used in construction, landscaping, and excavation. One of the critical components of this machine is its tracks, which provide the traction necessary for operating in rugged terrain. Understanding the importance of track maintenance and addressing common issues can extend the life of your T190 and improve its overall performance. This article will explore the key aspects of T190 tracks, common problems, maintenance tips, and best practices for ensuring optimal operation.
Importance of Tracks on the Bobcat T190
Tracks are a crucial part of any tracked machine, providing enhanced stability and better weight distribution compared to wheels. For the Bobcat T190, tracks offer several advantages:

• Improved Traction: Tracks distribute the machine’s weight evenly, which gives the T190 superior traction on soft, muddy, or uneven surfaces.
  
• Reduced Ground Pressure: Tracks help reduce the ground pressure exerted by the machine, which prevents it from sinking into soft ground or damaging delicate surfaces.
  
• Versatility: With tracks, the T190 can operate in a wide range of environments, from construction sites to forestry and landscaping jobs.
  

However, tracks require careful maintenance to ensure they continue to function optimally over time.
Common Issues with T190 Tracks
While Bobcat T190 tracks are built for durability, they can face several issues that affect performance. Here are some of the most common problems that operators encounter:

1. Track Wear and Tear:
   Over time, the rubber tracks of the T190 can show signs of wear, such as cracks, thinning, or holes. This wear is caused by friction, exposure to the elements, and the weight of the machine. If left unaddressed, worn tracks can compromise the loader’s performance and safety.
   
2. Track Alignment Issues:
   Misalignment occurs when the tracks are not positioned properly, which can lead to uneven wear. This issue often arises due to poor maintenance or worn track components, such as rollers, sprockets, or tensioners. Misalignment can cause the tracks to shift to one side, leading to increased wear and potential track failure.
   
3. Track Tension Problems:
   Proper track tension is essential for ensuring the smooth operation of the T190. If the tracks are too tight, they can cause excessive wear on the track drive components and reduce efficiency. On the other hand, if the tracks are too loose, they can slip off the sprockets, leading to operational disruptions and increased repair costs.
   
4. Track Slippage:
   Track slippage happens when the track moves over the sprockets without gripping them properly. This can be caused by worn sprockets, insufficient tension, or dirty or damaged track components. Slipping tracks decrease the machine's ability to transfer power to the ground, reducing efficiency and effectiveness.
   
5. Punctures and Damage:
   The T190’s rubber tracks can be punctured by sharp objects, such as rocks, nails, or metal debris on construction sites. Punctures can lead to loss of air pressure (if the tracks are air-filled) or a sudden loss of track integrity, requiring replacement or repair.
   

Maintaining T190 Tracks
Maintaining T190 tracks is essential for prolonging their lifespan and ensuring that the machine operates at peak performance. Below are some key maintenance tips to keep the tracks in top condition:

1. Regular Track Inspections:
   Conducting regular inspections of the tracks will help identify wear and tear early on. Look for signs of cracks, bulges, or uneven wear patterns on the rubber. Check for any debris lodged in the track components, such as rocks or dirt, as this can lead to premature wear.
   
2. Proper Track Tensioning:
   It’s important to maintain the proper track tension to ensure that the tracks are neither too tight nor too loose. Tighten or loosen the tracks as necessary by adjusting the tensioners. Check the manufacturer’s manual for the recommended tension specifications, as improper tension can cause unnecessary stress on the drive components.
   
3. Track Cleaning:
   Clean the tracks regularly, especially after working in muddy or snowy conditions. Mud, ice, and dirt can accumulate between the tracks and undercarriage, leading to wear and reducing the efficiency of the machine. A simple washdown with water can help keep the tracks free from debris and prevent clogging.
   
4. Check for Track Alignment:
   Misaligned tracks can lead to uneven wear, which may require premature replacement. Check the alignment of the tracks and adjust the components as necessary. Ensure that all parts, including the rollers, sprockets, and idlers, are properly aligned to avoid stress on the tracks.
   
5. Inspect Sprockets and Rollers:
   Sprockets and rollers play a significant role in the functioning of the tracks. Worn sprockets can cause the tracks to slip, while damaged rollers can contribute to uneven track wear. Inspect these components regularly and replace them if necessary.
   
6. Lubricate the Undercarriage:
   Lubricating the undercarriage components helps reduce friction and wear. Apply the recommended lubricants to the rollers, idlers, and other moving parts to maintain smooth operation.
   
7. Monitor Track Drive Motor:
   The track drive motor transfers power to the tracks, and a malfunctioning drive motor can cause track slippage. Regularly check the motor’s performance, fluid levels, and overall condition to ensure proper function.
   

Replacing T190 Tracks
When it’s time to replace the tracks, it’s essential to use high-quality replacements designed for the Bobcat T190. Aftermarket tracks may be available, but it’s recommended to purchase OEM (original equipment manufacturer) tracks to ensure compatibility and longevity. Here’s a step-by-step guide for replacing the tracks:

1. Lift the Machine: Use a jack or lifting equipment to raise the T190 off the ground. Ensure that it is securely supported before removing the tracks.
   
2. Remove the Old Tracks: Release the tension on the tracks and carefully remove the old tracks. You may need to disassemble certain components, such as the track rollers, to fully remove the tracks.
   
3. Install the New Tracks: Position the new tracks onto the undercarriage, ensuring that they are properly aligned. Tighten the tensioners to the correct specifications.
   
4. Test the Tracks: Once the new tracks are in place, lower the machine and test the tracks by moving the machine forward and backward. Check for any signs of misalignment, slippage, or abnormal noise.
   

Conclusion
The Bobcat T190 is a powerful and versatile machine, and its tracks play a critical role in its performance. Proper maintenance, timely repairs, and regular inspections are essential to ensuring that the tracks last for as long as possible. By following best practices for track tensioning, cleaning, and inspection, operators can avoid common issues such as track slippage, misalignment, and wear, ultimately reducing downtime and repair costs.
As with any heavy equipment, investing in quality replacement parts, staying on top of maintenance, and addressing issues promptly will help maximize the T190’s performance and reliability.
