Bobcat T200 Track System: Troubleshooting and Maintenance

[MikePhua]

The Bobcat T200 is a compact track loader designed to deliver exceptional performance in various construction, landscaping, and material handling tasks. Known for its versatility and power, the T200 is ideal for working in challenging terrains, such as soft soils or uneven surfaces, where wheeled equipment might struggle. One of the critical components of this machine is its track system, which provides traction, stability, and maneuverability. However, like any mechanical system, it requires proper maintenance and occasional troubleshooting.
In this article, we will explore common issues related to the Bobcat T200 track system, provide a detailed troubleshooting guide, and offer maintenance tips to keep your machine in top condition.
Understanding the Bobcat T200 Track System
The Bobcat T200 uses rubber tracks in combination with a suspension system that enhances performance and comfort. The tracks themselves are designed to distribute the weight of the machine evenly across a larger surface area, reducing ground pressure and improving the machine’s ability to move on soft or uneven ground. The system also includes several key components such as:

• Track Chains: These are the central elements that connect to the drive sprockets and rollers.
  
• Drive Sprockets: These sprockets engage with the track chains, transferring power from the engine to the tracks.
  
• Rollers and Idlers: These help guide the tracks and reduce wear.
  
• Track Tensioners: These are used to adjust the tightness of the tracks, ensuring they stay securely in place during operation.
  

Common Issues with the Bobcat T200 Track System
While the Bobcat T200’s track system is designed to be robust and reliable, several issues can arise with regular use. Identifying and addressing these issues promptly can prevent costly repairs and minimize downtime. Below are some common problems that operators may encounter:
1. Track Slipping or Skipping
Track slippage or skipping occurs when the tracks fail to maintain proper traction, causing them to move erratically. This issue can be caused by several factors:

• Track Tension Issues: If the tracks are too loose, they may slip over the drive sprockets. Conversely, overly tight tracks can cause excessive wear on the track system components.
  
• Worn Tracks: Over time, rubber tracks can wear down, especially in environments with rough or abrasive surfaces. Worn-out tracks may not engage properly with the sprockets, leading to slippage.
  
• Damaged Drive Sprockets: Worn or damaged drive sprockets may not grip the tracks as effectively, contributing to slippage.
  

2. Uneven Track Wear
Uneven wear on the tracks can reduce the performance and lifespan of the Bobcat T200. This type of wear often occurs due to improper tension, misalignment, or incorrect operation.

• Misaligned Tracks: If the tracks are not aligned properly, they may wear unevenly. This can happen if the track system is not installed correctly or if the rollers or idlers are damaged.
  
• Improper Track Tension: If the track tension is not within the specified range, it can lead to uneven wear. Too much tension can cause excessive friction, while too little tension can result in the track slipping and uneven wear patterns.
  

3. Track Off-Tracking
Off-tracking occurs when the track moves out of alignment, causing it to ride off the sprockets or rollers. This issue typically arises from one of the following causes:

• Damaged Track System Components: If the rollers, idlers, or sprockets are damaged or excessively worn, they may not guide the tracks properly.
  
• Improper Track Tension: Overly tight or loose tracks can cause off-tracking. Maintaining proper tension is crucial for ensuring smooth operation.
  
• Uneven Ground or Operating Conditions: Operating on uneven or sloped surfaces can increase the likelihood of off-tracking, especially if the machine is not level or balanced.
  

Troubleshooting Bobcat T200 Track Issues
To diagnose and address track issues with the Bobcat T200, follow this step-by-step troubleshooting guide:
1. Check Track Tension
Start by inspecting the track tension. Improper track tension is one of the most common causes of slippage, uneven wear, and off-tracking. Here’s how to check:

• Measure the Track Tension: Use a track tension gauge or measure the distance between the track and the roller at specific points to determine if the tension is within the recommended range.
  
• Adjust the Tension: If the tension is too loose, adjust the track tension using the machine’s track tensioner. Tighten it gradually, ensuring the track remains level and centered.
  

2. Inspect the Tracks for Wear and Damage
Check the tracks for any visible signs of wear, damage, or cracking. Worn-out tracks can cause slippage and uneven movement. If the tracks are damaged, they will need to be replaced. Look for:

• Cracks: Small cracks in the rubber can grow over time and lead to larger breaks.
  
• Chunking: Pieces of the rubber may break off, leading to reduced track performance.
  
• Uneven Wear Patterns: Look for uneven wear patterns that may indicate alignment or tension issues.
  

3. Examine the Drive Sprockets and Rollers
Next, inspect the drive sprockets and rollers for wear and damage. Worn-out sprockets can fail to engage the tracks properly, leading to slippage. Rollers should spin freely and evenly, without resistance or wobbling.

• Check for Wear: Inspect the teeth of the drive sprockets for signs of wear. If the teeth are rounded or damaged, replace the sprockets.
  
• Check Rollers: Rollers should be free of debris and able to rotate smoothly. If the rollers are damaged, replace them to ensure proper track alignment.
  

4. Inspect the Idlers and Track Guides
Ensure that the idlers and track guides are functioning properly. These components help keep the track on the right path and ensure smooth operation. If they are damaged or misaligned, they can cause off-tracking.

• Check Alignment: Make sure the idlers and track guides are properly aligned and not excessively worn.
  
• Replace Damaged Parts: If you find any damage, replace the idlers or track guides to restore proper alignment.
  

Maintaining the Bobcat T200 Track System
To prevent common track issues and extend the lifespan of the track system, perform regular maintenance on your Bobcat T200:

• Regular Track Inspections: Inspect the tracks, rollers, sprockets, and idlers at regular intervals. Catching wear and damage early can save on costly repairs and downtime.
  
• Lubrication: Keep all moving parts, including rollers and idlers, properly lubricated to reduce friction and wear.
  
• Proper Operation: Operate the machine on flat, even ground whenever possible to avoid unnecessary strain on the tracks. Avoid sharp turns or excessive speeds that could damage the track system.
  
• Clean Tracks: Regularly clean the tracks to remove debris, mud, or rocks that can cause wear or damage to the components.
  

Conclusion
The Bobcat T200 is a versatile and powerful machine, but its track system requires careful attention and maintenance to perform at its best. By understanding the potential issues, such as track slippage, uneven wear, and off-tracking, and following a detailed troubleshooting and maintenance process, you can keep your Bobcat T200 running smoothly. Regular inspections, proper tension adjustments, and timely repairs will help extend the life of your track system and improve your machine’s overall performance, making it a valuable asset for years to come.
