MTL25 and Tak TL150 Drive Control Issues

[MikePhua]

The drive control system is a critical component in ensuring the proper operation of heavy machinery. The MTL25 and Tak TL150 skid steer loaders are widely used in various work environments. However, drive control issues, if left unaddressed, can lead to reduced performance, operational difficulties, or even equipment damage. This article summarizes common drive control problems with the MTL25 and Tak TL150 loaders and provides potential solutions to address these issues.
Common Drive Control Problems
When using MTL25 and Tak TL150 skid steer loaders, common drive control problems include uneven control, stalling, sluggish movement, or unresponsive joysticks. These problems can negatively impact the equipment's performance and, in some cases, pose safety hazards.

1. Uneven Control or Stalling
   This problem typically manifests as sudden stops or unstable acceleration. Possible causes include issues with the drive pump, control valve failure, or unstable oil pressure.
   
2. Sluggish Movement
   If the loader’s movements become slow or unresponsive, it could be due to insufficient hydraulic fluid or air in the hydraulic system, resulting in uneven oil pressure.
   
3. Unresponsive Joystick
   This issue may stem from the control system itself, such as problems with the Electronic Control Unit (ECU), or loose or damaged connections between the joystick and the control system.
   

Solutions
Here are some common solutions to address drive control issues in the MTL25 and Tak TL150 skid steer loaders:

1. Check Hydraulic Oil and Pump
   Uneven control or stalling is often related to hydraulic oil supply issues. Start by checking the oil level, ensuring it is sufficient and free from contamination. If the oil is dirty, it should be replaced. Additionally, inspect the hydraulic pump to ensure it is functioning properly. If the pump is damaged or leaking, it needs to be replaced.
   
2. Inspect Control Valves and Lines
   Sluggish movement or unresponsive controls can often be traced back to issues with the control valve or hydraulic lines. Inspect the control valve to make sure it is operating smoothly without any blockages or leaks. If hydraulic lines are cracked or leaking, they should be replaced or repaired.
   
3. Check the Electronic Control System
   If the joystick is unresponsive, begin by checking the electrical connections in the control system. Ensure all connectors and cables are secure and free of corrosion. If there is no issue with the wiring, the Electronic Control Unit (ECU) may be faulty and require diagnosis or replacement.
   
4. Purge Air from the Hydraulic System
   Air in the hydraulic system can disrupt the stability of the oil pressure and the responsiveness of the system. By using the air bleed valve, you can remove any trapped air and improve control precision and operational efficiency.
   

Conclusion
Drive control issues in the MTL25 and Tak TL150 skid steer loaders are common problems that can significantly impact equipment performance. Timely diagnosis and resolution of these problems can improve efficiency and extend the lifespan of the equipment. Solutions include checking hydraulic oil, hydraulic pumps, control valves, electrical systems, and purging air from the system. Regular maintenance and inspections are crucial to preventing these issues and ensuring the loaders operate at peak performance.
