Troubleshooting and Maintenance of ASV SR80 Skid Steer Loader

[MikePhua]

The ASV SR80 is a powerful skid steer loader designed for a variety of tough tasks in construction, landscaping, and excavation. Like all heavy equipment, regular maintenance and troubleshooting are essential to ensure its longevity and efficient performance. In this article, we will explore some common issues with the ASV SR80, troubleshooting methods, and tips for keeping the machine in optimal condition.
1. Common Issues with the ASV SR80
While the ASV SR80 is a robust machine, some users have experienced typical skid steer problems that can affect its operation. These include issues with hydraulic performance, engine performance, and the drive system. Let’s look at some of the most common issues:

• Hydraulic Problems: Some users report sluggish or unresponsive hydraulic movements. This can be caused by low hydraulic fluid levels, clogged filters, or issues with the hydraulic pump.
  
• Engine Issues: Problems such as starting issues, stalling, or rough idling may occur. These can be related to fuel system problems, air filters, or even the battery and charging system.
  
• Drive System Failure: The ASV SR80 has a tracked undercarriage that can experience wear and tear over time. The drive motors, undercarriage components, or tracks themselves can sometimes be the source of performance issues.
  

2. Troubleshooting Hydraulic Issues
Hydraulic problems are common in many skid steers, and the ASV SR80 is no exception. To troubleshoot hydraulic issues, follow these steps:

• Check Fluid Levels: Low hydraulic fluid is one of the most common causes of poor performance. Inspect the fluid reservoir and top it off if necessary. Ensure that you are using the correct type of hydraulic fluid recommended by ASV.
  
• Inspect Filters: Clogged hydraulic filters can restrict fluid flow and cause sluggish operation. Replace filters at regular intervals as per the manufacturer’s recommendations to ensure smooth hydraulic operation.
  
• Look for Leaks: Leaks in hydraulic lines, hoses, or seals can also cause pressure loss, leading to poor hydraulic performance. Inspect all hydraulic components for visible signs of leaks.
  
• Test the Hydraulic Pump: If the fluid levels and filters are fine but the hydraulics are still not performing properly, the hydraulic pump might be failing. Have the pump pressure tested to confirm whether it needs repair or replacement.
  

3. Engine and Fuel System Troubleshooting
If the ASV SR80 is experiencing engine issues such as difficulty starting, stalling, or rough idling, the following steps can help identify the problem:

• Check the Fuel System: Fuel delivery issues can cause starting and running problems. Ensure that the fuel tank is full, and the fuel filter is clean. If the fuel system is clogged, replace the fuel filter and bleed the system to remove any air.
  
• Inspect the Air Filters: A dirty or clogged air filter can reduce engine performance and cause rough idling. Check the air filter and replace it if it appears dirty or damaged.
  
• Battery and Charging System: A weak or dead battery can cause starting issues. Test the battery voltage and check the alternator to ensure it is charging the battery correctly.
  
• Fuel Injectors and Glow Plugs: If the machine still has difficulty starting, check the fuel injectors and glow plugs. Worn or dirty injectors can cause fuel delivery problems, while faulty glow plugs can cause hard starting, especially in cold weather.
  

4. Drive System and Underbody Maintenance
The drive system and undercarriage are critical to the performance of the ASV SR80. Issues with the tracks, drive motors, or other related components can cause reduced power or mobility.

• Check Track Tension: If the tracks are too loose, they may slip or fail to provide the required traction. On the other hand, if the tracks are too tight, they can cause excessive wear. Ensure that the track tension is within the recommended range, and adjust it as necessary.
  
• Inspect Drive Motors: If the loader is experiencing a loss of power or erratic movement, the drive motors may be to blame. Inspect the motors for any signs of wear or damage and check the hydraulic fluid level to ensure proper operation.
  
• Examine Underbody Components: The undercarriage of the ASV SR80 is built to handle heavy loads, but over time, components such as rollers, sprockets, and the idler assembly can wear down. Regularly inspect these parts for signs of wear and replace them as needed to maintain the overall efficiency of the machine.
  

5. Preventative Maintenance Tips
To ensure the ASV SR80 runs efficiently and lasts for many years, regular preventative maintenance is key. Here are some important tips to keep in mind:

• Regular Fluid Changes: Change the hydraulic fluid and engine oil at the recommended intervals to ensure optimal performance. Clean fluids help prevent damage to the system and keep the machine running smoothly.
  
• Inspect Tracks and Undercarriage: Regularly inspect the tracks for wear, and check for loose bolts or parts in the undercarriage. Keeping the tracks in good condition will ensure better performance and longevity.
  
• Grease the Loader: Lubricating the moving parts of the loader, such as pins, bushings, and hydraulic arms, is essential for reducing wear and preventing corrosion. Follow the manufacturer's lubrication schedule to ensure all components are well-maintained.
  
• Check Electrical System: Ensure that the battery and wiring are in good condition. Clean any corrosion from battery terminals and check the alternator to ensure the battery is charging properly.
  

6. Conclusion
The ASV SR80 skid steer loader is a reliable machine for tough jobs, but like any piece of heavy equipment, it requires regular maintenance and occasional troubleshooting to keep it in top working condition. By following the tips outlined in this article and addressing any issues promptly, operators can minimize downtime and maximize the performance and lifespan of the machine. Regular maintenance, such as checking hydraulic fluids, inspecting the engine, and maintaining the undercarriage, is essential for keeping the ASV SR80 operating at its best.
