Troubleshooting and Understanding the ASV RC100 Undercarriage: When Tracks Angle Outward at the Bottom

[MikePhua]

The ASV RC100 is a robust compact track loader, highly valued for its performance and versatility, especially in difficult terrain. However, like all heavy machinery, it may encounter issues from time to time. One common problem reported by operators is the outward angling of the tracks at the bottom of the undercarriage. This issue can affect the performance of the machine, leading to reduced stability, premature wear, and even operational downtime. In this article, we will break down the possible causes of this issue, explore troubleshooting steps, and offer practical tips for maintaining the undercarriage to prevent this problem.
Understanding the ASV RC100 Undercarriage
The ASV RC100 is equipped with a sophisticated undercarriage designed for superior traction and durability. It features rubber tracks that provide better flotation and reduce the impact on the terrain compared to steel tracks. The machine is also known for its high ground clearance, allowing it to operate effectively in challenging environments like soft soils, mud, and rocky terrains.
The undercarriage of a track loader like the RC100 typically consists of several key components:

• Tracks: These are the large rubber or steel elements that make contact with the ground and provide traction.
  
• Track Tensioner: A mechanism that helps maintain the proper track tension to ensure optimal performance.
  
• Rollers and Idlers: These components support the weight of the machine and help the tracks run smoothly.
  
• Sprockets: Teeth that engage with the track to provide movement.
  
• Track Adjusters: Mechanisms that allow for adjustments in track tension, ensuring proper alignment.
  

The issue of tracks angling outward at the bottom typically involves the track tensioning system, track alignment, or undercarriage components such as the rollers, sprockets, or track adjusters.
Causes of Tracks Angling Outward at the Bottom
Several factors can contribute to the outward angling of the tracks at the bottom of the ASV RC100 undercarriage. Understanding these causes is essential to resolving the issue effectively.
1. Improper Track Tension
One of the most common causes of the tracks angling outward is improper track tension. When the track tension is either too tight or too loose, it can cause the tracks to not sit properly on the rollers and sprockets, leading to misalignment.

• Symptoms of improper tension:
  • Tracks that appear to bow outward at the bottom
    
  • Tracks becoming loose or slipping off the sprocket teeth
    
  • Uneven wear on the track and undercarriage components
    
• How to Fix It: To correct this issue, the track tension should be adjusted to the manufacturer’s specifications. Proper tension ensures that the tracks stay aligned with the rollers and sprockets, minimizing unnecessary stress and wear.
  

2. Worn Track Rollers or Idlers
Over time, the track rollers or idlers can wear down, causing misalignment and uneven track placement. If the rollers or idlers are excessively worn, they may not provide the necessary support for the tracks, leading to the outward angling of the tracks.

• Symptoms of worn rollers or idlers:
  • Excessive play in the rollers
    
  • Tracks wobbling or tilting outward
    
  • Unusual sounds, such as squeaking or grinding, from the rollers
    
• How to Fix It: Inspect the rollers and idlers for signs of wear or damage. Replace worn components to restore proper support and alignment for the tracks.
  

3. Damaged or Misaligned Sprockets
The sprockets are responsible for engaging with the tracks and providing forward motion. If the sprockets are misaligned, damaged, or excessively worn, they can cause the tracks to move improperly, leading to the tracks angling outward at the bottom.

• Symptoms of damaged sprockets:
  • Uneven wear on the teeth of the sprockets
    
  • Tracks not staying engaged with the sprockets
    
  • The machine becoming sluggish or unresponsive
    
• How to Fix It: Check the sprockets for damage or wear. If necessary, replace the sprockets to ensure proper engagement with the tracks.
  

4. Track Adjuster Malfunction
The track adjuster is responsible for maintaining the proper tension in the tracks. If the adjuster is malfunctioning, it may not apply enough tension to keep the tracks properly aligned, causing the tracks to shift and angle outward.

• Symptoms of track adjuster malfunction:
  • Tracks are excessively loose or too tight
    
  • The track adjuster shows visible signs of damage or leakage
    
  • The machine struggles to maintain proper track tension
    
• How to Fix It: Inspect the track adjuster for leaks, damage, or failure to properly adjust the tension. If necessary, repair or replace the track adjuster to restore proper track alignment.
  

5. Bent or Damaged Undercarriage Frame
In rare cases, the undercarriage frame itself can become bent or damaged, which may lead to misalignment of the entire track system. This can cause the tracks to angle outward at the bottom.

• Symptoms of frame damage:
  • Visible bending or cracking of the undercarriage frame
    
  • Difficulty aligning the tracks or keeping them properly tensioned
    
  • Unstable machine behavior, especially when turning or maneuvering
    
• How to Fix It: If the undercarriage frame is damaged, it may need to be repaired or replaced. Professional inspection is necessary to assess the severity of the damage and determine the best course of action.
  

Troubleshooting and Solutions
Here’s a list of troubleshooting steps for resolving the outward angling of tracks on the ASV RC100:

• Outward Angling of Tracks: Improper track tension. Solution: Adjust the track tension to manufacturer’s specifications.
  
• Track Wobbling or Angling Outward: Worn rollers or idlers. Solution: Replace worn rollers or idlers to restore track support.
  
• Uneven Track Engagement: Damaged or misaligned sprockets. Solution: Inspect and replace damaged sprockets.
  
• Loose or Tight Tracks: Malfunctioning track adjuster. Solution: Repair or replace the track adjuster.
  
• Misaligned Tracks: Damaged undercarriage frame. Solution: Repair or replace the undercarriage frame.
  

Maintaining the ASV RC100 Undercarriage
Preventing future issues with the undercarriage of your ASV RC100 can be achieved through regular maintenance. Key maintenance tasks include:

• Track Tension Adjustments: Regularly check the track tension and adjust it to keep it within the recommended range.
  
• Undercarriage Inspections: Inspect the rollers, idlers, sprockets, and track adjusters for signs of wear or damage. Replace components as needed to maintain proper track alignment.
  
• Lubrication: Keep the moving parts of the undercarriage well-lubricated to reduce friction and wear. Use the appropriate lubricants recommended by the manufacturer.
  
• Track Cleaning: Regularly clean the tracks and undercarriage to remove dirt, mud, and debris that can cause unnecessary wear or misalignment.
  

Conclusion
The ASV RC100 is a powerful and versatile track loader, but like all heavy machinery, it requires attention and maintenance to perform at its best. The issue of tracks angling outward at the bottom is often a result of improper track tension, worn components, or a malfunctioning track adjuster. By regularly inspecting and maintaining the undercarriage, operators can prevent this issue and extend the life of the machine. Proper troubleshooting, timely repairs, and adherence to the manufacturer’s maintenance guidelines will keep your ASV RC100 performing optimally, ensuring smooth operation on even the most challenging terrain.
