Troubleshooting LS-170 New Holland Skid Steer Issues

[MikePhua]

The LS-170 New Holland skid steer loader is a popular machine in construction and landscaping due to its compact size, powerful hydraulics, and versatility. However, like any piece of heavy machinery, it can encounter problems during its lifespan. This article discusses common issues with the LS-170 and provides helpful troubleshooting tips to assist operators in keeping the machine running efficiently.
1. Engine Starting Issues
One of the most common problems operators face with the LS-170 is difficulty starting the engine. If the machine does not start, it is essential to go through the following checks:

• Battery Condition: A dead or weak battery is a frequent cause of starting issues. First, check the battery voltage using a multimeter. If the battery is undercharged, attempt to jump-start it or replace the battery if necessary.
  
• Fuel System: If the battery is not the issue, check the fuel system. A clogged fuel filter, air in the fuel lines, or an empty fuel tank can prevent the engine from starting. Ensure the fuel tank has sufficient fuel and replace the fuel filter if it appears clogged.
  
• Starter Motor: A faulty starter motor can also prevent the engine from cranking. If you hear a clicking sound when you turn the ignition key but the engine doesn't turn over, it may indicate a problem with the starter. Consider inspecting or replacing the starter motor.
  

2. Hydraulic Performance Issues
Hydraulic problems can severely impact the functionality of a skid steer loader, as they affect the movement of the boom and the lift arms. If the LS-170 experiences sluggish or unresponsive hydraulics, the following causes should be considered:

• Low Hydraulic Fluid: Check the hydraulic fluid level. If the fluid is low, top it off with the manufacturer-recommended fluid. Running the machine with low fluid can cause overheating and damage to the hydraulic pump.
  
• Dirty or Clogged Filters: Over time, hydraulic filters can become clogged with dirt and debris. Regularly inspect and replace the hydraulic filters to ensure smooth operation.
  
• Air in the Hydraulic Lines: Air bubbles in the hydraulic lines can cause erratic movement or a lack of power. If this occurs, it may be necessary to bleed the hydraulic system to remove trapped air.
  
• Hydraulic Pump Failure: If none of the above solutions resolve the issue, the hydraulic pump might be malfunctioning. Signs of a failing hydraulic pump include grinding noises or a significant loss of lifting power. A professional should inspect the pump and consider a replacement if necessary.
  

3. Transmission and Drive Problems
The transmission is responsible for driving the skid steer forward and backward. If the LS-170 experiences poor traction, erratic movement, or difficulty shifting gears, the following checks should be made:

• Transmission Fluid Levels: Check the transmission fluid level and ensure it is at the recommended level. Low transmission fluid can cause slipping or shifting problems.
  
• Faulty Drive Motors: If the transmission fluid is in good condition and the problem persists, the drive motors may be malfunctioning. Inspect the drive motors for signs of wear or damage, as these components are crucial for movement.
  
• Drive Chain Issues: If there is a loss of power to the wheels or the tracks are not moving properly, inspect the drive chain for wear or damage. A loose or broken chain can cause operational issues and should be adjusted or replaced as needed.
  

4. Overheating and Cooling Problems
Overheating is another common issue, especially when the machine is used for extended periods or in hot environments. Here are some potential causes:

• Low Coolant Levels: The engine coolant must be maintained at an appropriate level for the engine to operate effectively. Low coolant levels can lead to overheating. Check the radiator and coolant reservoir for proper levels and top them off if needed.
  
• Clogged Radiator: A clogged radiator can restrict airflow, leading to overheating. Clean the radiator and check for any blockages, including debris or dirt buildup. Regularly washing the radiator fins can prevent this issue.
  
• Faulty Thermostat: A malfunctioning thermostat can prevent the engine from cooling properly. If the engine consistently runs hot, replacing the thermostat may be necessary.
  

5. Electrical and Control System Issues
Electrical issues are another common problem that can prevent the LS-170 from operating at full capacity. If there are any issues with starting, running, or controlling the machine, here are some steps to troubleshoot:

• Fuses and Relays: Inspect the fuses and relays in the electrical system. A blown fuse or faulty relay can prevent the machine from operating. Replace any damaged fuses or relays.
  
• Wiring Connections: Loose or corroded wiring connections can cause intermittent issues with the electrical system. Inspect the wiring harness for any visible damage, corrosion, or loose connections, and repair or replace as necessary.
  
• Control System Errors: The LS-170's control system may throw error codes if there is an issue with the sensors or electronic components. Use a diagnostic tool to retrieve any error codes and refer to the operator’s manual for troubleshooting steps.
  

6. Undercarriage and Track Problems
The undercarriage plays a vital role in the stability and performance of the LS-170. Common issues related to the tracks and undercarriage include:

• Track Tension: If the tracks are too tight or too loose, it can cause operational problems. Check the track tension regularly and adjust it according to the manufacturer’s specifications. Proper track tension ensures efficient movement and prevents undue wear on the undercarriage components.
  
• Worn Tracks: Over time, the tracks on a skid steer can wear out, leading to reduced traction and efficiency. If the tracks are showing significant wear, consider replacing them to restore optimal performance.
  
• Track Roller Damage: Track rollers are responsible for supporting the weight of the machine and maintaining proper track alignment. If the rollers are damaged or worn, they can cause uneven track wear and should be replaced.
  

7. Conclusion
The LS-170 New Holland skid steer loader is an essential piece of equipment for many industries. However, like all machinery, it can experience a range of issues that may hinder its performance. Regular maintenance and prompt troubleshooting can help extend the lifespan of the loader and ensure it operates at its full potential. By addressing common issues related to the engine, hydraulics, transmission, cooling system, electrical system, and undercarriage, operators can prevent downtime and keep the LS-170 running efficiently.
