Adjusting Drive Chains on New Holland LS170 Skid Steer Loaders

[MikePhua]

Introduction
The New Holland LS170 is a robust skid steer loader, widely used in construction and agricultural applications. One of its critical components is the drive chain system, which transmits power from the engine to the wheels. Proper maintenance and adjustment of these chains are essential for optimal performance and longevity of the machine.
Understanding the Drive Chain System
The LS170 utilizes a drive chain system that connects the engine's output to the wheel motors. This system is housed within chain cases located on each side of the machine. Over time, these chains can stretch or wear, leading to slack that may affect the machine's performance.
Signs of Improper Chain Tension
Operators should be vigilant for the following indicators of chain issues:

• Unusual Noises: Clunking or grinding sounds during operation may suggest chain slack or wear.
  
• Uneven Movement: The machine may exhibit jerky or uneven movement, especially when turning.
  
• Visual Inspection: Excessive slack visible in the chain can be a clear sign of the need for adjustment.
  

Adjusting the Drive Chains
To adjust the drive chains on the LS170:

1. Lift the Machine: Securely elevate the front of the skid steer using appropriate lifting equipment.
   
2. Access the Chain Cases: Remove any covers or panels to expose the chain cases on both sides of the machine.
   
3. Inspect the Chains: Check for slack by rotating the wheels and observing the chain's movement.
   
4. Adjust the Tension: Locate the tensioning mechanism, which may involve loosening bolts and repositioning the chain case or adjusting tensioners.
   
5. Reassemble and Test: After adjustments, reassemble any removed components, lower the machine, and test the operation to ensure proper chain tension.
   

Maintenance Tips

• Regular Inspections: Periodically check the drive chains for signs of wear or slack.
  
• Proper Lubrication: Ensure the chains are adequately lubricated to reduce friction and wear.
  
• Timely Replacements: Replace chains and sprockets at the first sign of significant wear to prevent further damage.
  

Conclusion
Maintaining proper chain tension on the New Holland LS170 is crucial for ensuring efficient operation and extending the lifespan of the machine. By following the outlined adjustment procedures and adhering to regular maintenance practices, operators can keep their skid steer loaders performing at their best.
