The Takeuchi TB 135 is a popular compact excavator known for its reliable performance in tight spaces and demanding construction environments. With a weight of around 3.5 tons, it's a machine often used for urban projects, small-scale earthworks, landscaping, and utility installations. One of the common issues that operators may face is when the track of the TB 135 becomes slow or sluggish. This problem can significantly affect the machine's performance, limiting its efficiency and speed during operations.
Understanding the root causes of a slow-moving track and implementing proper solutions can help maintain the TB 135’s productivity. Below is a detailed analysis of the issue, possible causes, and recommended fixes.
Possible Causes of Slow Track Movement
When the track on a compact excavator like the TB 135 slows down, the issue can stem from several potential sources, ranging from mechanical failures to simple maintenance oversights. Below are the most common causes:
1. Hydraulic System Problems
The TB 135 relies heavily on its hydraulic system to control the track drive motors, which allow the machine to move. A slow track can often be traced back to hydraulic issues, such as low hydraulic fluid levels, dirty hydraulic filters, or a failing pump.
The tracks of the TB 135, like any tracked machine, must be properly tensioned to ensure smooth movement. Too much tension can cause the tracks to move sluggishly, while too little tension can lead to slippage and potential damage.
As with any heavy machinery, wear and tear on parts like the track chain, sprockets, rollers, or bushings can impact the movement of the tracks. These components should be regularly checked for signs of wear.
The working conditions can also contribute to slow-moving tracks. For example, if the excavator is used in particularly muddy, sandy, or rocky conditions, the tracks can become clogged or filled with debris. This can add excessive weight to the machine or reduce the contact between the tracks and the ground, impairing its ability to move effectively.
5. Engine Power Issues
A slow track may sometimes be a symptom of an engine power deficiency. If the engine is not producing sufficient power, it can fail to provide enough hydraulic pressure or overall energy to propel the tracks at the desired speed. This could be due to fuel system problems, clogged air filters, or internal engine wear.
Diagnostic Steps for Troubleshooting
To properly diagnose the issue, follow these steps:
1. Check Hydraulic Fluid Levels and Condition
1. Regular Fluid and Filter Changes
A slow-moving track on a Takeuchi TB 135 excavator can stem from several sources, including hydraulic issues, track tension problems, undercarriage wear, environmental factors, or engine performance. By conducting thorough inspections and addressing potential causes systematically, operators can restore the machine's performance and avoid downtime. Regular maintenance, such as fluid changes, track adjustments, and engine checks, is key to keeping the TB 135 running efficiently. Through proactive care, operators can ensure that their excavators continue to deliver reliable, fast, and effective service on every job.

1. Hydraulic System Problems
The TB 135 relies heavily on its hydraulic system to control the track drive motors, which allow the machine to move. A slow track can often be traced back to hydraulic issues, such as low hydraulic fluid levels, dirty hydraulic filters, or a failing pump.
- Low Fluid Levels: Hydraulic fluid is critical for the functioning of the machine's drive motors. If the fluid levels drop too low, the machine may not have enough power to operate the tracks efficiently.
- Contaminated Fluid: Over time, hydraulic fluid can become contaminated with dirt, debris, or metal particles. This can cause blockages or excessive wear in the hydraulic pump or motors, reducing the efficiency of the drive system.
- Faulty Hydraulic Pump or Motor: If there’s an issue with the hydraulic pump or track drive motor, it can result in inadequate power delivery to the tracks, leading to slow movement.
The tracks of the TB 135, like any tracked machine, must be properly tensioned to ensure smooth movement. Too much tension can cause the tracks to move sluggishly, while too little tension can lead to slippage and potential damage.
- Over-tightened Tracks: Over-tightening the tracks can create extra friction, slowing down the machine’s speed and putting unnecessary strain on the track drive system.
- Under-tightened Tracks: If the tracks are too loose, they can slip, causing poor performance and a lack of traction, leading to the appearance of a slow-moving track.
As with any heavy machinery, wear and tear on parts like the track chain, sprockets, rollers, or bushings can impact the movement of the tracks. These components should be regularly checked for signs of wear.
- Worn-out Track Chain: The track links can wear down over time, affecting the smoothness and speed of the track movement.
- Damaged Sprockets: The sprockets that engage with the track links can become worn or damaged, reducing the efficiency of the track drive system.
- Worn Rollers: If the rollers that guide the track along the undercarriage are worn out, they may not allow for smooth movement, resulting in sluggish performance.
The working conditions can also contribute to slow-moving tracks. For example, if the excavator is used in particularly muddy, sandy, or rocky conditions, the tracks can become clogged or filled with debris. This can add excessive weight to the machine or reduce the contact between the tracks and the ground, impairing its ability to move effectively.

A slow track may sometimes be a symptom of an engine power deficiency. If the engine is not producing sufficient power, it can fail to provide enough hydraulic pressure or overall energy to propel the tracks at the desired speed. This could be due to fuel system problems, clogged air filters, or internal engine wear.
Diagnostic Steps for Troubleshooting
To properly diagnose the issue, follow these steps:
1. Check Hydraulic Fluid Levels and Condition
- Start by inspecting the hydraulic fluid levels and ensuring they are within the recommended range. If the fluid is low, top it up with the appropriate type of fluid specified in the user manual.
- Inspect the fluid for contaminants. If it appears dirty or has a burnt smell, it may need to be replaced, and the hydraulic filters should be cleaned or changed.
- Check the hydraulic pump and track drive motors for signs of wear or failure. Look for leaks, unusual noises, or inconsistent power delivery. If any of these signs are present, professional servicing or replacement may be required.
- Check the track tension according to the manufacturer’s specifications. If the tension is too tight or too loose, adjust it accordingly.
- Track adjustment should be done carefully to avoid excessive strain on the system while ensuring proper grip and movement.
- Inspect the track chain, sprockets, and rollers for signs of excessive wear. If any of these components are significantly worn or damaged, they may need to be replaced.
- Regular cleaning and lubrication of the undercarriage can help prevent premature wear and ensure smoother track operation.
- If the machine has been used in harsh conditions, check for debris, mud, or dirt accumulation. Clean the undercarriage and tracks thoroughly to ensure there is no blockage or build-up that could impede movement.
- If no issues are found with the hydraulic system or track components, the problem may lie with the engine. Check the fuel system, air filters, and exhaust to ensure proper engine performance.
- Look for any signs of engine underperformance, such as reduced power or irregular sounds, and address them promptly.
1. Regular Fluid and Filter Changes
- To prevent hydraulic issues, regularly check and replace hydraulic fluid and filters. This will not only improve performance but also extend the life of the hydraulic system.
- Ensure that the tracks are properly tensioned and regularly inspect for wear on the track chain and undercarriage components. Cleaning and lubrication can prevent unnecessary wear and improve track movement.
- Perform routine checks on the engine, including changing air filters and inspecting fuel lines for any clogs or leaks. A clean, well-maintained engine will provide better power output, which is essential for smooth track movement.
