The Takeuchi TB35S is a compact mini-excavator designed for efficiency, versatility, and high performance in tight working conditions. One of its key features is its auxiliary hydraulics system, which allows the machine to power a variety of attachments, such as breakers, augers, and grapple buckets. In this article, we will explore the auxiliary hydraulics system on the TB35S, including its components, function, common issues, and troubleshooting steps.
What is the Auxiliary Hydraulics System?
The auxiliary hydraulics system on a mini-excavator like the Takeuchi TB35S provides hydraulic power to attachments that require additional force or movement. These systems are often referred to as "auxiliary circuits" and operate independently of the main boom or dipper arm hydraulics. They are essential for running a range of specialized attachments that can enhance the machine’s versatility.
The system includes a dedicated pump, hydraulic lines, and control valves. The auxiliary hydraulics allow the operator to control the flow and pressure of fluid to attachments via joystick controls or additional buttons on the operator’s console.
Components of the Auxiliary Hydraulics System
The Takeuchi TB35S auxiliary hydraulics system consists of several key components, each working together to provide reliable performance for attachments:
1. Auxiliary Hydraulic Pump
The auxiliary pump provides the necessary hydraulic pressure to power various attachments. It works in parallel with the primary pump, which drives the main functions of the excavator, such as the arm and bucket movement.
The control valve regulates the flow and pressure of the hydraulic fluid that is directed to the auxiliary circuit. It allows operators to control the operation of the attachment based on the task at hand.
The hydraulic lines carry the pressurized fluid from the auxiliary pump to the attachment. These hoses are often equipped with quick-connect couplings that make it easy to attach or detach hydraulic-powered tools.
Some models of the Takeuchi TB35S are equipped with a high-flow auxiliary hydraulics option, which provides greater flow and pressure for more demanding attachments, such as hydraulic hammers or mulchers.
While the auxiliary hydraulics system on the TB35S is designed for durability, certain issues can arise over time. Understanding these problems and their potential causes can help operators troubleshoot and resolve them efficiently.
1. Weak or Insufficient Hydraulic Flow
One of the most common issues with auxiliary hydraulics is weak or insufficient hydraulic flow to the attachment. This problem can result in poor performance, such as an attachment not moving at full capacity or operating too slowly.
Hydraulic leaks are another frequent issue with auxiliary systems. These leaks can cause a drop in pressure and affect the performance of the attachment.
In some cases, the attachment may not respond as expected to the operator’s controls. This could involve the attachment failing to move, jerking, or moving erratically.
Overheating of the hydraulic fluid can cause the system to perform poorly, potentially leading to component damage. This is particularly problematic during heavy or extended use.
To keep your Takeuchi TB35S operating smoothly, it's essential to follow a troubleshooting checklist to diagnose and fix common hydraulic problems. Below are some essential steps to take when troubleshooting auxiliary hydraulics issues:
1. Check Fluid Levels
Always ensure that the hydraulic fluid is at the recommended level. Low fluid levels can result in poor hydraulic performance.
2. Inspect Filters and Hoses
Visually inspect all hydraulic hoses and filters for wear, cracks, or damage. A clogged filter can restrict flow, while a damaged hose can cause leaks.
3. Test the Auxiliary Pump
If you suspect that the auxiliary system is underperforming, testing the pump’s output pressure can provide insights into whether the pump is still functioning at its optimal capacity.
4. Verify Attachment Compatibility
Ensure that the attachment is designed to work with the TB35S’s auxiliary hydraulic system. Some attachments may require different flow rates or pressures.
5. Bleed the Hydraulic System
If air is suspected in the system, it may cause the attachment to behave erratically. Bleeding the system will remove any trapped air and restore proper fluid flow.
Maintaining the Auxiliary Hydraulics System
Proper maintenance of the auxiliary hydraulics system can prevent many of the common issues listed above. Regular checks of the system, fluid levels, and attachment connections should be part of your routine equipment maintenance.
1. Regular Fluid Changes
Change the hydraulic fluid regularly to prevent contamination and ensure smooth operation. This is especially important if you use the machine in harsh or dusty environments.
2. Filter Replacement
Replace hydraulic filters based on the manufacturer’s recommendations or more frequently if you notice reduced performance.
3. Hose and Fitting Inspections
Inspect all hoses and couplings for wear and tear. Damaged hoses should be replaced immediately to prevent further issues.
4. Proper Attachment Usage
Always ensure that the attachments are compatible with the machine’s auxiliary hydraulic specifications. Overloading the system can cause excessive wear and even failure.
Conclusion
The Takeuchi TB35S’s auxiliary hydraulics system is a powerful tool that enhances the versatility of the excavator, allowing it to handle a wide range of attachments for different tasks. However, like any hydraulic system, it requires regular maintenance and proper troubleshooting to avoid common issues such as weak flow, leaks, or overheating. By following the recommended maintenance practices, inspecting the system regularly, and addressing problems as they arise, operators can ensure that the auxiliary hydraulics system continues to operate efficiently and effectively, maximizing the performance of the TB35S.
