Replacing Drive Chains on the Cat 268B with Loegering VTS Track System

[MikePhua]

Introduction
The Caterpillar 268B, a versatile skid steer loader, is designed for various applications, from landscaping to construction. When equipped with the Loegering Versatile Track System (VTS), it offers enhanced flotation and stability, making it suitable for challenging terrains. However, like any mechanical system, the VTS requires regular maintenance to ensure optimal performance. One critical component is the drive chain, which can experience wear and may need replacement over time.
Understanding the Loegering VTS Track System
The Loegering VTS is a rubber track undercarriage that bolts directly to a skid steer's standard hubs. It features a forward-positioned front idler wheel and a rear idler placed farther back than the rear hub. This design provides improved stability when digging, backing out of trenches, hauling, and dumping heavy loads. The system's bi-directional suspension adjusts independently from one side of the machine to the other, maximizing track footprint and evenly distributing horsepower on uneven terrain.
Signs Indicating Drive Chain Wear
Regular inspection of the drive chains is essential to detect early signs of wear:

• Unusual Noise: Any rattling or clanking sounds during operation may indicate loose or worn chains.
  
• Slippage: If the machine struggles to maintain speed or power, the drive chain might be slipping.
  
• Visual Inspection: Look for elongation of the chain links or visible damage such as cracks or missing teeth.
  

Steps to Replace the Drive Chain
Replacing the drive chain on the Cat 268B with the Loegering VTS involves several steps:

1. Preparation: Park the machine on a level surface, engage the parking brake, and disconnect the battery to ensure safety.
   
2. Remove the Track System: Detach the track system from the hubs, similar to removing tires. This process may require assistance due to the weight of the components.
   
3. Access the Drive Chain: Open the inspection cover to access the drive chain. In some cases, it may be necessary to remove additional panels or components to gain full access.
   
4. Remove the Old Chain: Carefully remove the old drive chain, noting the orientation and positioning for reinstallation.
   
5. Install the New Chain: Position the new chain in place, ensuring it aligns correctly with the sprockets and other components.
   
6. Reassemble the Track System: Reattach the track system to the hubs, ensuring all bolts are tightened to the manufacturer's specifications.
   
7. Adjust Tension: Proper chain tension is crucial for optimal performance. Refer to the machine's manual for the correct tension specifications and adjust accordingly.
   
8. Test Operation: After reassembly, conduct a test run to ensure the machine operates smoothly without any unusual noises or issues.
   

Maintenance Tips to Extend Drive Chain Life
To prolong the lifespan of the drive chain and other components:

• Regular Inspections: Frequently check for signs of wear or damage.
  
• Proper Lubrication: Ensure the drive chain is adequately lubricated to reduce friction and wear.
  
• Avoid Overloading: Do not exceed the machine's rated capacity to prevent undue stress on the drive chain.
  
• Cleanliness: Keep the track system clean from debris and mud, which can cause abrasion and wear.
  

Conclusion
Maintaining the drive chain on the Cat 268B equipped with the Loegering VTS is vital for ensuring the machine's longevity and performance. Regular inspections, timely replacements, and proper maintenance practices can help operators avoid unexpected downtime and costly repairs. By following the outlined steps and tips, operators can keep their equipment running efficiently and effectively.
