Troubleshooting the Hydraulic Pump on Takeuchi TB 135: Key Considerations and Solutions

[MikePhua]

Hydraulic systems are at the heart of most heavy equipment, driving everything from lifting arms to bucket movement. For compact excavators like the Takeuchi TB 135, the hydraulic pump is crucial for ensuring that the machinery operates smoothly and efficiently. When hydraulic issues arise, such as low pressure, erratic behavior, or total pump failure, it can halt productivity and lead to costly downtime.
This article explores common issues with the hydraulic pump of the Takeuchi TB 135, offering solutions and tips for troubleshooting. We'll also discuss the importance of maintenance, the role of hydraulic components, and the most effective ways to keep the pump running smoothly.
Common Hydraulic Pump Problems in the Takeuchi TB 135
The Takeuchi TB 135 is a versatile and powerful compact excavator, often used for tasks such as trenching, digging, and lifting in construction and landscaping projects. However, like all mechanical systems, its hydraulic pump can encounter several issues, including:
1. Low Hydraulic Pressure
Low hydraulic pressure is a common problem for many compact excavators, including the TB 135. When the hydraulic pump fails to maintain proper pressure, the machine may struggle to perform basic tasks like lifting the arm or operating the bucket.
Possible Causes:

• Low Fluid Levels: The most common cause of low pressure is low hydraulic fluid levels, often due to leaks or improper maintenance.
  
• Clogged Filters: A dirty or clogged hydraulic filter can restrict fluid flow, causing a drop in pressure.
  
• Damaged Pump Components: If the internal parts of the hydraulic pump, such as the pistons or gears, are worn or damaged, it can result in low pressure.
  

Solution:

• First, check the hydraulic fluid level and top it up if necessary. Ensure the fluid is clean and free from contaminants.
  
• Inspect the hydraulic filters and clean or replace them if they appear dirty or clogged.
  
• If these steps don’t resolve the issue, it may be necessary to examine the pump itself for internal damage. This requires more advanced troubleshooting and, potentially, professional repair or replacement of the pump.
  

2. Erratic Pump Performance
Sometimes, the hydraulic pump on the TB 135 may operate inconsistently, with sudden surges of power or erratic movement. This can manifest as jerky movements in the boom or bucket, or a sudden drop in lifting capacity.
Possible Causes:

• Air in the Hydraulic System: Air trapped in the hydraulic lines can cause unpredictable performance, as it disrupts the flow of fluid.
  
• Worn Pump Components: Over time, pump components like the valves, seals, or pistons may wear down, leading to inconsistent performance.
  
• Contaminated Fluid: Contaminants in the hydraulic fluid can affect the operation of the pump and cause erratic performance.
  

Solution:

• Bleed the hydraulic system to remove any trapped air. Ensure that the fluid is free from contaminants and that the system is clean.
  
• If worn components are suspected, the pump will need to be disassembled and inspected for damaged or worn parts. Replacing seals, valves, or pistons may be necessary.
  

3. Complete Pump Failure
In some cases, the hydraulic pump in the TB 135 may fail completely, resulting in a loss of all hydraulic functionality. This is a critical issue that requires immediate attention to avoid complete equipment downtime.
Possible Causes:

• Severe Damage to Pump Components: Over time, constant wear and tear can cause the pump components to degrade to the point of failure. This can happen if the machine has been running with low hydraulic fluid or without proper maintenance.
  
• Overheating: Excessive heat can cause the hydraulic pump to fail, particularly if the fluid is not properly cooled or if the system is overworked.
  

Solution:

• If the pump has failed completely, the only solution is to replace the hydraulic pump. It is recommended to work with a certified technician to ensure that the pump is installed correctly.
  
• To prevent overheating in the future, make sure the hydraulic fluid is regularly changed and that the cooling system is functioning properly.
  

Maintaining the Hydraulic System for Longevity
Preventative maintenance is key to avoiding costly repairs and ensuring the longevity of the hydraulic pump in your Takeuchi TB 135. Regularly checking the hydraulic fluid level, replacing filters, and cleaning the system can go a long way in preventing pump failure and maintaining optimal performance.
1. Regular Fluid Checks
One of the simplest yet most effective ways to maintain your hydraulic system is by checking the hydraulic fluid levels regularly. Keep an eye out for leaks and ensure that the fluid remains at the proper level. Low or contaminated fluid can cause significant damage to the pump and other hydraulic components.
2. Clean or Replace Filters
Hydraulic filters should be cleaned or replaced periodically to ensure that debris does not clog the system. Contaminated fluid can cause internal damage to the pump and other parts of the system. Regularly replacing filters is an inexpensive way to maintain the health of your equipment.
3. Use the Right Fluid
Using the correct type of hydraulic fluid is essential for optimal pump performance. Always consult the manufacturer’s manual to determine the proper fluid specifications for your Takeuchi TB 135. The wrong fluid can lead to premature wear or damage to the pump, seals, and other components.
4. Monitoring for Leaks
Hydraulic systems are sensitive to leaks, which can result in a loss of pressure and fluid contamination. Regularly inspect the hydraulic hoses and connections for signs of wear or leakage. Catching leaks early can prevent more significant damage to the system.
Conclusion: The Importance of Timely Repairs and Proper Maintenance
The hydraulic pump is a critical component of the Takeuchi TB 135 and ensures that the machine operates efficiently. If you experience low pressure, erratic performance, or complete pump failure, it’s essential to address these issues promptly to prevent further damage and reduce downtime.
By regularly maintaining your hydraulic system, checking for leaks, and using the correct hydraulic fluid, you can extend the life of the hydraulic pump and other components in your TB 135. If problems persist despite routine maintenance, consider reaching out to a qualified technician for a thorough inspection and potential repair or replacement of the hydraulic pump.
In the world of heavy equipment, ensuring that your machinery runs smoothly is essential to keeping productivity high and costs low. With regular maintenance and proactive troubleshooting, your Takeuchi TB 135 can continue to serve you effectively on job sites for years to come.
