[MikePhua]

The Kubota SVL 90-2 is a powerful and efficient compact track loader, widely used in construction and agricultural applications. While the machine performs well under most conditions, users may encounter some common issues over time. This article summarizes the common problems faced by SVL 90-2 owners and provides maintenance tips to help keep the equipment running efficiently and extend its service life.
Common Issues and Symptoms

1. Lack of Power or Difficulty Starting
   In some cases, the SVL 90-2 may experience difficulty starting or exhibit a lack of power. This issue is often related to the fuel system, starting battery, or air filter. If the machine is slow to start or shows signs of reduced power, checking the fuel and battery should be the first step, ensuring they are not contaminated or worn out.
   
2. Hydraulic System Problems
   The hydraulic system is critical to the smooth operation of a track loader. If there are hydraulic oil leaks, unstable pressure, or sluggish hydraulic movements, it may indicate issues with the hydraulic pump, hoses, or seals. These problems typically require professional inspection and repair to address effectively.
   
3. Vibration and Noise
   Unusual vibrations or noise during operation could stem from wear in the track system, drivetrain, or swinging components. Inspecting the tracks for looseness and checking the gears and bearings for lubrication or damage are essential to resolve this issue.
   
4. Electrical System Failures
   Electrical issues are often characterized by malfunctioning displays, warning lights, or unexpected power loss. These issues are usually caused by low battery voltage, short circuits, or poor electrical connections. Regular checks of the electrical wiring and connections can prevent these types of failures.
   

Maintenance Tips

1. Regular Fuel System Checks
   Maintaining the fuel system is critical. Regularly replace the fuel filter and ensure that there are no contaminants or debris in the fuel lines. Keeping the fuel system clean prevents damage to the fuel pump or injectors and helps maintain optimal engine performance.
   
2. Inspect Hydraulic Oil and Seals
   Periodically check the quality and level of the hydraulic oil to ensure the system is free from air and contaminants. Inspect the seals for any signs of damage, and replace them promptly to prevent oil leaks that could impair hydraulic performance.
   
3. Lubricate and Inspect the Track System
   The track system is one of the most crucial components of the SVL 90-2. Regularly lubricate the track rollers, gears, and bearings to prevent excessive wear. Inspect the tracks for any looseness or damage, as this could lead to operational issues and additional damage to the machine.
   
4. Electrical System Preventative Checks
   Conduct regular checks of the battery voltage and electrical wiring to ensure all connections are stable. Preventing poor connections and low battery voltage will help avoid electrical issues, especially during colder weather when batteries are more prone to failure.
   
5. Engine and Cooling System Inspections
   Regularly inspect engine oil, coolant levels, and the overall condition of the cooling system. Ensure that the cooling system is clean and functioning correctly, especially during high-load operations, to prevent overheating and engine failure.
   

Conclusion
The Kubota SVL 90-2 is a reliable and powerful compact track loader, ideal for a variety of job sites. By performing regular maintenance and inspections, operators can ensure the machine runs smoothly and lasts longer. Key maintenance areas include the fuel system, hydraulic system, track system, and electrical system. Following these maintenance tips will not only help prevent common issues but also improve overall machine performance, reduce downtime, and maximize productivity.
