New Holland LS170 Skid Steer Loader: Common Issues and Solutions
#1
The New Holland LS170 is a versatile and popular skid steer loader, designed for a variety of tasks, including material handling, digging, and grading. However, like any piece of machinery, it is not immune to mechanical issues. This article provides an overview of common problems faced by LS170 owners and operators, along with potential solutions and troubleshooting tips to maintain the loader in optimal working condition.
Common Issues with the New Holland LS170
  1. Hydraulic System Problems
    • One of the most common issues reported by LS170 owners is related to the hydraulic system. These problems can manifest as slow or erratic movement of the loader's arms or bucket, or even complete failure to lift heavy loads.
    • Possible Causes:
      • Low hydraulic fluid levels.
      • Contaminated hydraulic fluid.
      • Leaks in the hydraulic system (hoses, fittings, or cylinders).
      • Faulty hydraulic pump or control valves.
    • Solutions:
      • First, check the hydraulic fluid levels and top them up if necessary. Ensure the fluid is clean and free of contaminants.
      • Inspect hoses, fittings, and cylinders for leaks and repair any damaged components.
      • If the pump or control valves are malfunctioning, they may need to be replaced.
  2. Starting Issues
    • Another common issue with the LS170 is difficulty starting the engine. This can be caused by a variety of factors, including electrical problems or fuel delivery issues.
    • Possible Causes:
      • Faulty starter motor or solenoid.
      • Dead or weak battery.
      • Issues with the fuel system, such as clogged fuel filters or air in the fuel lines.
      • Bad connections in the electrical system.
    • Solutions:
      • Test the starter motor and solenoid. If either component is faulty, it may need to be replaced.
      • Check the battery charge and connections, and replace the battery if necessary.
      • Inspect the fuel system, replacing any clogged filters and ensuring proper fuel flow.
  3. Engine Performance Issues
    • The LS170 is equipped with a diesel engine, and like any diesel engine, it may experience performance issues from time to time. This can manifest as poor power, stalling, or high fuel consumption.
    • Possible Causes:
      • Dirty air filter.
      • Clogged fuel injectors or air intake system.
      • Fuel system issues (fuel pump or fuel filters).
      • Faulty engine sensors or controls.
    • Solutions:
      • Replace the air filter if it is dirty or clogged.
      • Clean or replace the fuel injectors and ensure that the air intake system is clear.
      • Inspect the fuel system, and replace the fuel filter or fuel pump if necessary.
      • Check the engine sensors and control modules for faults.
  4. Electrical Issues
    • Electrical problems can also affect the LS170, including issues with lights, instrumentation, or other electrical components. These issues often arise from faulty wiring, bad connections, or blown fuses.
    • Possible Causes:
      • Blown fuses or relays.
      • Corroded or loose electrical connections.
      • Faulty switches or sensors.
    • Solutions:
      • Inspect the fuses and relays and replace any that are blown.
      • Check all electrical connections for corrosion or looseness and clean or tighten them as needed.
      • Replace faulty switches or sensors that may be affecting the electrical system.
  5. Tire Wear and Traction Issues
    • Tires on the LS170 can wear out over time, especially if the loader is frequently used on rough or uneven terrain. Worn tires can reduce traction, affecting the loader's performance.
    • Possible Causes:
      • Worn or damaged tires.
      • Incorrect tire pressure.
      • Poor ground conditions (e.g., wet or muddy surfaces).
    • Solutions:
      • Inspect the tires for signs of wear or damage, and replace them if necessary.
      • Check and adjust the tire pressure according to the manufacturer's specifications.
      • Use the loader on more suitable terrain or equip it with tires designed for better traction on slippery surfaces.
Preventative Maintenance Tips
To avoid the common issues mentioned above and keep the New Holland LS170 in top working condition, regular maintenance is essential. Below are some preventative maintenance tips:
  • Hydraulic System: Regularly check hydraulic fluid levels and inspect hoses and fittings for leaks. Change the hydraulic fluid at the intervals recommended in the operator's manual.
  • Engine: Perform regular oil changes and inspect air and fuel filters. Make sure the fuel system is clean and free of contaminants.
  • Battery and Electrical System: Inspect and clean electrical connections, check the battery’s charge, and replace the battery as needed.
  • Tires and Tracks: Check tire pressure regularly and inspect tires for wear or damage. Keep tires clean and free of debris.
  • General Cleaning: Keep the loader clean to prevent dirt and debris from interfering with moving parts or hydraulic systems.
Conclusion
The New Holland LS170 is a reliable and powerful skid steer loader, but like all machines, it requires regular maintenance and troubleshooting to stay in top condition. Addressing common problems such as hydraulic issues, starting problems, and engine performance can prevent more costly repairs down the line.
By following proper maintenance practices and addressing issues promptly, operators can ensure the LS170 continues to perform well on the job site. Regular inspections, fluid checks, and replacing worn parts when necessary will help extend the life of the machine and keep it running efficiently.
