[MikePhua]

The Takeuchi TB 035 is a compact, versatile mini-excavator that has been widely used in construction, landscaping, and urban utility work. Known for its powerful engine, small footprint, and exceptional maneuverability, the TB 035 is a popular choice for projects that require both precision and power in tight spaces. However, like any heavy machinery, the Takeuchi TB 035 can experience operational issues over time. These problems often stem from various mechanical and electrical components, and troubleshooting can be challenging without a clear understanding of the machine's systems.
In this article, we will explore common issues faced by TB 035 owners, their causes, and possible solutions to help ensure the machine runs smoothly for years to come.
Common Issues with Takeuchi TB 035
Like all machinery, the Takeuchi TB 035 can encounter several issues related to its various systems. Below, we’ll break down some of the most common problems that owners face, and how to troubleshoot and fix them.
1. Engine Starting Problems
One of the most common issues that operators face with the TB 035 is difficulty starting the engine. This issue could be due to a variety of reasons, from electrical failures to fuel delivery problems.

• Possible Causes:
  • Battery Failure: A weak or dead battery is often the cause of starting issues, especially in cold weather.
    
  • Starter Motor Malfunction: If the starter motor is worn or malfunctioning, it may not engage properly, preventing the engine from turning over.
    
  • Fuel Issues: Clogged fuel filters, air in the fuel lines, or poor-quality fuel can prevent the engine from starting. Air intake issues or a failing fuel pump can also be contributing factors.
    
• Troubleshooting and Solutions:
  • First, check the battery voltage and terminals for any corrosion or loose connections. A multimeter can be used to check battery output. If the voltage is too low, recharge or replace the battery.
    
  • Inspect the starter motor for any signs of damage. If the motor is faulty, it will need to be replaced.
    
  • Check the fuel system for blockages, particularly the fuel filter and pump. Clean or replace any clogged filters and ensure there is no air trapped in the fuel lines. If the fuel pump is faulty, replacement will be necessary.
    

2. Hydraulic System Issues
Another common problem with the Takeuchi TB 035 involves its hydraulic system. Problems such as slow operation or a complete loss of hydraulic power can occur due to several causes.

• Possible Causes:
  • Low Hydraulic Fluid: Insufficient fluid in the hydraulic system can lead to poor performance or a complete failure of the hydraulics.
    
  • Hydraulic Pump Failure: If the hydraulic pump becomes worn or damaged, it may fail to deliver the required pressure for lifting or digging.
    
  • Clogged Filters: The hydraulic system relies on clean fluid, and clogged filters can restrict fluid flow, causing performance issues.
    
• Troubleshooting and Solutions:
  • Start by checking the hydraulic fluid level. If it is low, top it up with the recommended fluid. Make sure to also check for any visible leaks.
    
  • Inspect the hydraulic pump for any signs of wear or damage. If the pump is malfunctioning, it may need to be repaired or replaced.
    
  • Clean or replace the hydraulic filters regularly to prevent blockages and ensure smooth operation.
    

3. Track Tensioning Problems
The TB 035’s undercarriage is an essential part of its performance, providing mobility across different terrains. A common problem involves issues with the track tensioning system, which can lead to inefficient operation and even track damage.

• Possible Causes:
  • Improper Tension: If the tracks are too loose or too tight, it can cause damage to the tracks and other undercarriage components.
    
  • Damaged Track Tensioner: Over time, the track tensioner can wear out or fail, leading to improper tension.
    
• Troubleshooting and Solutions:
  • Check the track tension to ensure it is within the proper range. Typically, the tension should be tight enough to prevent the track from slipping but not so tight as to cause undue wear on the components.
    
  • Inspect the track tensioner for any signs of damage or malfunction. If necessary, adjust or replace the tensioner to maintain proper track tension.
    

4. Overheating Problems
The Takeuchi TB 035, like any excavator, can experience overheating issues. This can lead to engine shutdown, decreased performance, and long-term damage if not addressed.

• Possible Causes:
  • Clogged Radiator or Cooling System: Dirt and debris can accumulate in the radiator or cooling fins, reducing the efficiency of the cooling system.
    
  • Low Coolant Levels: If the coolant level is too low, the engine may overheat.
    
  • Faulty Thermostat or Water Pump: A malfunctioning thermostat or water pump can prevent the coolant from circulating properly, causing overheating.
    
• Troubleshooting and Solutions:
  • Inspect the radiator and cooling system for any blockages or buildup. Clean the radiator and cooling fins regularly to ensure proper airflow.
    
  • Check the coolant level and top it up if necessary. Be sure to use the recommended coolant for the machine.
    
  • Test the thermostat and water pump. If either is malfunctioning, replace the faulty part to restore proper coolant circulation.
    

5. Joystick Control Malfunctions
The TB 035 is equipped with joystick controls for precise operation of its boom, arm, and bucket. If these controls become unresponsive or erratic, it can hinder the operator's ability to perform tasks effectively.

• Possible Causes:
  • Electrical Failures: Issues with the wiring or connections in the joystick control system can result in unresponsive controls.
    
  • Hydraulic Issues: A failure in the hydraulic system that controls the boom or bucket could be affecting the joystick's performance.
    
  • Damaged Joystick or Control Cables: If the joystick itself or the control cables are damaged, they may fail to transmit signals properly.
    
• Troubleshooting and Solutions:
  • Inspect the wiring and connectors associated with the joystick control system. Tighten any loose connections and check for signs of wear or damage.
    
  • Test the hydraulic system to ensure that the hydraulic fluid is flowing correctly to the relevant actuators.
    
  • If the joystick is damaged, it will need to be replaced. Likewise, inspect the control cables and replace them if they are found to be faulty.
    

Preventative Maintenance Tips
To avoid issues with the Takeuchi TB 035, regular maintenance is essential. Here are a few tips to keep the excavator in good working condition:

• Change Hydraulic Fluids and Filters Regularly: Hydraulic fluid and filters should be replaced as per the manufacturer’s recommendation to maintain smooth operation.
  
• Inspect Tracks Frequently: Check the track tension and wear regularly, and replace any damaged components before they lead to more severe issues.
  
• Monitor Engine and Cooling System: Regularly inspect the engine, radiator, and cooling system for signs of wear or blockages.
  
• Keep Electrical Connections Clean and Secure: Ensure all electrical connections are tight and free from corrosion, particularly around the starter motor and battery.
  

Conclusion
The Takeuchi TB 035 is a reliable and powerful machine for a variety of construction and landscaping tasks. However, like any heavy equipment, it can experience issues with its engine, hydraulic system, tracks, and controls. Regular inspection, proper maintenance, and prompt attention to any problems will ensure that the TB 035 remains in good working condition for years. By understanding the common issues and their causes, operators can effectively troubleshoot and resolve these problems, minimizing downtime and maximizing productivity on the job site.
