Common Issues with ASV 120 Skid Steer and Solutions

[MikePhua]

The ASV 120 skid steer is a robust piece of machinery well-regarded for its versatility and high-performance capabilities, especially in tough terrains. However, like all heavy equipment, it’s not without its challenges. Common issues with the ASV 120 can affect its performance, leading to downtime and costly repairs if not addressed promptly. In this article, we’ll explore some of the frequent issues faced by ASV 120 operators, common troubleshooting steps, and how to prevent further complications.
Hydraulic System Problems
One of the most reported issues with the ASV 120 skid steer involves its hydraulic system. Hydraulic problems can lead to a decrease in power, erratic movement, or even total failure of the loader's functionality. The ASV 120, like many skid steers, relies heavily on its hydraulic system to operate critical components such as the lifting arms and attachment functions.
Possible Causes of Hydraulic Issues

• Low Hydraulic Fluid: The simplest cause of poor hydraulic performance is a low hydraulic fluid level. Skid steers work in environments that expose their hydraulic systems to heavy loads and sometimes extreme conditions. It’s crucial to monitor the hydraulic fluid regularly and top it off when needed.
  
• Contaminated Hydraulic Fluid: Dirt or debris entering the hydraulic system can cause blockages or reduce the fluid's effectiveness. If contamination is suspected, the fluid should be drained and replaced, and the system should be flushed.
  
• Faulty Hydraulic Pump or Motor: If the hydraulic system is sluggish or non-responsive, the hydraulic pump or motor may be failing. These components should be inspected and replaced if necessary.
  
• Leaking Hoses or Fittings: Leaks in the hydraulic hoses or fittings can lead to a loss of pressure, causing reduced lifting power or erratic movements. Inspect the system regularly for visible signs of wear or leakage.
  

Electrical System Failures
Electrical issues are another common problem with the ASV 120. These issues can range from intermittent power loss to complete electrical failure, causing the skid steer to stop working altogether.
Electrical Issues to Watch For

• Battery and Charging Problems: A weak or dead battery is one of the most frequent culprits. Battery terminals should be cleaned and checked for corrosion. Additionally, the alternator or charging system must be functioning properly to keep the battery charged during operation.
  
• Blown Fuses or Wiring Issues: If certain functions of the skid steer stop working, it’s worth checking the fuses and wiring for breaks or corrosion. Any faulty electrical connections should be addressed to prevent further failures.
  
• Faulty Sensors or ECU Issues: The ASV 120 is equipped with an electronic control unit (ECU) and several sensors that monitor its performance. A faulty sensor or malfunctioning ECU can cause incorrect readings, error codes, and potential shutdowns. These issues should be diagnosed using diagnostic tools to identify and fix the faulty components.
  

Engine and Starting Problems
Engine issues can lead to starting failures, which is a serious problem when you need the machine to operate. Several factors contribute to engine malfunctions, ranging from fuel system issues to more complex mechanical failures.
Common Engine Issues

• Fuel System Problems: Clogged fuel filters or faulty fuel injectors can cause the engine to misfire, run rough, or fail to start. Regular maintenance of the fuel system, including changing filters and ensuring the fuel is clean, can prevent many of these problems.
  
• Air Filter Blockages: A clogged air filter can starve the engine of air, leading to poor performance or even failure to start. Inspect the air filter regularly, especially if working in dusty conditions.
  
• Starter Motor Failure: A worn-out or faulty starter motor is another reason why the ASV 120 might not start. In some cases, the starter solenoid may fail, preventing the starter motor from turning the engine over.
  

Undercarriage and Track Issues
Given that the ASV 120 is a track loader, the condition of the undercarriage and tracks is crucial to its performance. Track-related problems can significantly impact the machine's mobility and efficiency.
Track Wear and Tear

• Track Tension: If the tracks are too loose or too tight, the machine may experience difficulty in moving, or the tracks may wear out prematurely. Regularly check and adjust the track tension as needed to ensure optimal performance.
  
• Track Damage: The tracks can be damaged by rough terrain, debris, or prolonged use. Inspect the tracks for cracks, cuts, or excessive wear, which can lead to a loss of traction and increased repair costs.
  
• Roller and Sprocket Wear: The rollers and sprockets that guide the tracks can wear out over time. When they are worn down, they may not grip the track properly, leading to inefficiency and potential track failure.
  

Overheating Problems
The ASV 120, like all heavy machinery, is prone to overheating, especially when working in hot conditions or under heavy loads for extended periods. Overheating can cause significant damage to the engine and other key components.
Causes of Overheating

• Low Coolant Levels: Ensure that the coolant levels are maintained within the recommended range. Low coolant can cause the engine to overheat quickly.
  
• Radiator Clogs: Debris or dirt blocking the radiator can reduce airflow, leading to overheating. Clean the radiator regularly, especially after working in dusty or dirty environments.
  
• Faulty Cooling Fan: If the cooling fan isn’t working properly, it can’t cool the engine efficiently. This may require the inspection and replacement of the fan or fan motor.
  

General Maintenance and Troubleshooting Tips

• Regular Inspections: Perform regular visual inspections of the hydraulic system, electrical components, tracks, and engine. Look for signs of wear, leaks, or damage.
  
• Scheduled Service Intervals: Follow the manufacturer’s recommended service intervals for changing fluids, replacing filters, and inspecting critical components.
  
• Use Diagnostic Tools: Invest in a diagnostic tool that can read error codes from the ASV 120's ECU. This will help identify issues quickly and avoid unnecessary guesswork during repairs.
  

Conclusion
While the ASV 120 is a reliable skid steer, regular maintenance and awareness of potential issues can help keep it running smoothly. Hydraulic system malfunctions, electrical failures, engine issues, and track wear are some of the most common problems faced by operators. However, with proper care, attention, and timely troubleshooting, these issues can often be addressed before they result in major downtime or costly repairs.
