Troubleshooting Weak Curl and Auxiliary Hydraulics in Takeuchi TL130 Skid Steer

[MikePhua]

Skid steer loaders like the Takeuchi TL130 are powerful machines designed for a variety of tasks in construction, landscaping, and agriculture. However, like any piece of heavy equipment, they can experience mechanical issues over time. One common problem operators face is weak hydraulic performance, particularly with the curl function and auxiliary hydraulics. This issue can significantly affect the machine's performance, making it difficult to operate attachments effectively. In this guide, we will explore the possible causes of weak curl and auxiliary hydraulics in the Takeuchi TL130 and offer troubleshooting tips and solutions.
Understanding the Hydraulic System in the Takeuchi TL130
The Takeuchi TL130 is equipped with a hydraulic system that powers both the lift arms and the auxiliary hydraulics. The system uses a set of pumps, valves, and cylinders to transmit hydraulic fluid to the various functions of the skid steer.

1. Curl Function:
   • The curl function is responsible for the bucket’s ability to tilt backward and forward. This action is crucial for scooping, lifting, and dumping materials. When the curl function is weak, the bucket may not curl fully, or it may lack the force needed to perform tasks efficiently.
     
2. Auxiliary Hydraulics:
   • The auxiliary hydraulics are used to power additional attachments, such as auger drills, post drivers, or grapples. Weak auxiliary hydraulics can prevent attachments from functioning properly, leading to reduced performance on the job site.
     

Common Causes of Weak Curl and Auxiliary Hydraulics
Several factors can contribute to weak curl and auxiliary hydraulics in the Takeuchi TL130. Understanding these causes is crucial for effective troubleshooting.

1. Low Hydraulic Fluid Levels:
   • One of the most common causes of weak hydraulics is low hydraulic fluid levels. If the fluid is low, the pump cannot generate the necessary pressure, resulting in weak performance across the machine’s hydraulic functions, including the curl and auxiliary hydraulics.
     
2. Contaminated Hydraulic Fluid:
   • Contaminated hydraulic fluid can also lead to hydraulic issues. Dirt, debris, and water in the fluid can cause wear and tear on hydraulic components such as pumps, valves, and cylinders. This can result in reduced efficiency and weak hydraulic power.
     
3. Hydraulic Pump Issues:
   • The hydraulic pump is responsible for generating the pressure needed to operate the skid steer’s hydraulic functions. A worn-out or malfunctioning pump may fail to provide adequate pressure, leading to weak curl or auxiliary hydraulics.
     
4. Clogged Filters:
   • Over time, the hydraulic system’s filters can become clogged with debris and contaminants. Clogged filters restrict the flow of hydraulic fluid, reducing pressure and causing weak hydraulic performance.
     
5. Faulty Relief Valve:
   • The relief valve is designed to protect the hydraulic system from excessive pressure. If the relief valve is malfunctioning or incorrectly adjusted, it can cause a drop in pressure, leading to weak hydraulics.
     
6. Leaking Hydraulic Hoses or Fittings:
   • Hydraulic hoses or fittings that are cracked or worn out can leak fluid, reducing the pressure within the hydraulic system. Leaks can cause weak hydraulic functions, including a lack of power in the curl and auxiliary hydraulics.
     
7. Problems with Hydraulic Cylinders:
   • Hydraulic cylinders that are damaged or worn can also result in weak hydraulic performance. If a cylinder is leaking or malfunctioning, it will not be able to generate the required force for lifting, curling, or powering attachments.
     

Step-by-Step Troubleshooting
If you are experiencing weak curl or auxiliary hydraulics on your Takeuchi TL130, follow these troubleshooting steps to identify and fix the problem.
1. Check Hydraulic Fluid Levels

• Start by checking the hydraulic fluid levels using the dipstick or sight gauge on the machine. If the fluid level is low, refill the hydraulic reservoir with the recommended fluid type. Ensure that the fluid is clean and free of contaminants.
  

2. Inspect the Hydraulic Fluid for Contaminants

• If the hydraulic fluid looks dirty, contaminated, or discolored, it may need to be replaced. Flushing the hydraulic system and replacing the fluid can help resolve issues caused by contaminants. Make sure to also clean or replace the hydraulic filters.
  

3. Examine the Hydraulic Pump

• Check the hydraulic pump for any signs of wear or damage. Listen for unusual noises, such as whining or grinding, which could indicate pump failure. If the pump is malfunctioning, it may need to be replaced.
  

4. Inspect the Filters

• Hydraulic filters play a critical role in keeping the fluid clean and free of debris. Inspect the filters for clogging and replace them if necessary. Ensure the correct filter type is used and that it’s installed correctly.
  

5. Check for Leaks

• Examine the hydraulic hoses, fittings, and connections for any signs of leaks. If you notice any fluid leaking from the hoses or fittings, replace the damaged parts. Tighten any loose fittings, as they can also cause a loss of hydraulic pressure.
  

6. Inspect the Relief Valve

• Check the relief valve for proper operation. If the relief valve is malfunctioning, it could be causing the hydraulic pressure to drop. A faulty valve may need to be replaced or adjusted to the correct pressure setting.
  

7. Test the Hydraulic Cylinders

• If the above steps do not resolve the issue, inspect the hydraulic cylinders. Check for any visible signs of damage, leaks, or wear. If a cylinder is faulty, it will need to be repaired or replaced.
  

Preventative Maintenance Tips for Skid Steer Hydraulics
To avoid hydraulic issues in the future, follow these preventative maintenance practices:

1. Regular Fluid Checks:
   • Check hydraulic fluid levels regularly and top up as needed. Ensure that the fluid is clean and free of contaminants. Regular fluid changes can help extend the life of your hydraulic system.
     
2. Routine Filter Replacement:
   • Replace hydraulic filters at recommended intervals to ensure that the fluid remains clean. Clogged filters can lead to poor hydraulic performance and damage to other components.
     
3. Monitor Pressure Settings:
   • Regularly monitor the hydraulic system’s pressure to ensure that it is operating within the recommended range. Low or excessive pressure can lead to reduced performance and damage to the system.
     
4. Check for Leaks:
   • Inspect hydraulic hoses, fittings, and cylinders for leaks regularly. Fixing small leaks early can prevent more significant issues down the line.
     
5. Keep the Machine Clean:
   • Dirt and debris can quickly find their way into the hydraulic system and cause contamination. Keep the skid steer clean and ensure that the hydraulic system is sealed properly.
     

Conclusion
Weak curl and auxiliary hydraulics can significantly affect the performance of your Takeuchi TL130 skid steer. By following the troubleshooting steps outlined in this guide, you can identify the cause of the problem and take appropriate action. Whether it’s checking fluid levels, replacing filters, or inspecting the pump and cylinders, early intervention and regular maintenance are key to keeping your skid steer running smoothly. Taking care of the hydraulic system will ensure that your Takeuchi TL130 performs at its best, reducing downtime and improving productivity on the job site.
