Takeuchi has long been a trusted name in the construction equipment industry, with machines like the TB260 compact excavator becoming highly popular due to their versatility and efficiency. One of the essential maintenance tasks for the TB260, like any other heavy machinery, involves the proper choice of gear oils. Gear oils play a critical role in ensuring that the machine's transmission system operates smoothly, reduces wear, and prevents overheating. This article focuses on the considerations when using GL-4 gear oil in the Takeuchi TB260, exploring its properties, benefits, and why it is an ideal choice for this equipment.
Understanding GL-4 Gear Oil
GL-4, or Gear Lubricant 4, is a specific classification of gear oil designed to provide adequate protection for machinery under moderate load conditions. This grade of oil is generally used for automotive and industrial gears, particularly in applications where extreme pressure isn’t typically encountered but lubrication under moderate stress is still essential.
GL-4 oil differs from GL-5 oil in several ways. GL-5 oils are formulated for high-pressure, high-performance applications (like those found in heavy-duty trucks), whereas GL-4 oils are designed for moderate-pressure environments, like the gear systems in compact excavators and backhoes.
The key features of GL-4 oil include:
The Takeuchi TB260 compact excavator is designed to handle various construction tasks, including digging, lifting, and precise earthmoving. It requires gear oil that can withstand the rigors of these operations without risking damage to its transmission or drivetrain. GL-4 gear oil provides the right balance of lubrication and durability for this type of equipment. Here’s why it’s the preferred choice:
While GL-4 gear oil offers many benefits, it’s essential to select the correct viscosity and oil type that aligns with the Takeuchi TB260's specifications. Takeuchi provides guidelines for the recommended oil types, typically based on the climate and operational conditions of the machine. The following factors should be considered:
Using the correct gear oil is only part of the equation when it comes to maintaining the Takeuchi TB260's transmission and gear systems. Regular maintenance practices will ensure the longevity and smooth operation of the machine. Below are some recommended maintenance steps:
Despite the benefits of using GL-4 gear oil in the TB260, there are a few considerations that operators should keep in mind:
The Takeuchi TB260 is a powerful and efficient compact excavator that, when maintained properly, can deliver outstanding performance on a variety of construction sites. GL-4 gear oil is a suitable choice for the TB260 due to its ability to provide moderate load protection, effective gear lubrication, and corrosion resistance under a range of operational conditions. By selecting the correct oil and adhering to regular maintenance practices, operators can ensure that their TB260 continues to operate at peak efficiency, reducing downtime and repair costs while enhancing productivity on the job site.

The key features of GL-4 oil include:
- Moderate Load Protection: GL-4 oils are ideal for machinery like the Takeuchi TB260 that operates under moderate loads.
- Gear Teeth Protection: GL-4 oils are designed to provide a stable film between gear teeth, reducing wear and preventing corrosion.
- Versatility in Use: GL-4 is commonly used in a wide range of equipment, from construction machinery to passenger cars, making it a popular choice for various industries.
The Takeuchi TB260 compact excavator is designed to handle various construction tasks, including digging, lifting, and precise earthmoving. It requires gear oil that can withstand the rigors of these operations without risking damage to its transmission or drivetrain. GL-4 gear oil provides the right balance of lubrication and durability for this type of equipment. Here’s why it’s the preferred choice:
- Moderate Load Operation: The TB260 works under typical construction loads but doesn’t typically face the extreme pressures associated with larger, heavier machinery. The moderate load capabilities of GL-4 make it ideal for this equipment.
- Optimal Lubrication for Gears: The TB260’s drivetrain and gearbox require a gear oil that will prevent wear and provide smooth operation during digging or traveling across rough terrain. GL-4 oil offers high shear stability and helps maintain a smooth surface for the gears, preventing premature wear.
- Corrosion Resistance: With the exposure to dust, dirt, and moisture on construction sites, the TB260’s gears are susceptible to rust. GL-4 gear oil contains additives that help protect against corrosion, extending the life of the gear components.
- Wide Temperature Range: The TB260 works in a variety of environments, from hot, dry areas to cold, damp conditions. GL-4 gear oils are designed to work across a broad temperature range, ensuring consistent performance no matter the climate.
While GL-4 gear oil offers many benefits, it’s essential to select the correct viscosity and oil type that aligns with the Takeuchi TB260's specifications. Takeuchi provides guidelines for the recommended oil types, typically based on the climate and operational conditions of the machine. The following factors should be considered:
- Viscosity: The recommended viscosity grade is crucial to ensure that the gear oil flows correctly under different temperatures. For the TB260, using a multi-viscosity GL-4 oil is common, as it provides optimal performance in various environmental conditions. Depending on the operating temperature range, oils such as SAE 80W-90 or SAE 85W-140 are often used.
- API Rating: It’s important to choose an oil that meets the American Petroleum Institute (API) standards for gear oils. GL-4 oils with an API rating of GL-4 or higher will ensure compatibility and reliable performance in the TB260’s transmission and differential systems.
Using the correct gear oil is only part of the equation when it comes to maintaining the Takeuchi TB260's transmission and gear systems. Regular maintenance practices will ensure the longevity and smooth operation of the machine. Below are some recommended maintenance steps:
- Regular Oil Changes: Depending on the operating hours and conditions, the gear oil should be changed at intervals specified in the owner’s manual. It’s typically recommended to change the oil every 500-1,000 hours of operation, or as dictated by the manufacturer.
- Inspect for Leaks: The gear oil should be checked for leaks regularly. Any leaks in the system can lead to oil loss, causing insufficient lubrication and potentially damaging components. Seals, gaskets, and the gearbox housing should be inspected frequently.
- Check Oil Quality: Over time, the oil can become contaminated with dirt, dust, or metallic particles. A simple visual inspection or a viscosity test can help identify when the oil needs to be changed. A burnt smell or darkening color of the oil may indicate that it is time for a change.
- Monitor Gear Performance: Any changes in the TB260’s performance, such as grinding noises, difficulty shifting, or reduced operational efficiency, may be signs of low oil levels or contamination. These issues should be addressed immediately to prevent further damage.
- Follow Manufacturer’s Recommendations: Always follow Takeuchi's recommendations for the type and grade of oil. Using an oil with incorrect specifications can lead to premature wear, decreased fuel efficiency, and increased maintenance costs.
Despite the benefits of using GL-4 gear oil in the TB260, there are a few considerations that operators should keep in mind:
- Compatibility with Older Oils: If the machine has been previously running on a different grade of gear oil, especially a GL-5 oil, it may require a flushing procedure to remove contaminants before switching to GL-4. Mixing oils with different additives could lead to performance issues.
- Environment and Operating Conditions: If the TB260 is used in extreme conditions, such as in hot climates or for very heavy-duty tasks, operators may need to upgrade to a more robust oil like GL-5. However, for standard construction tasks, GL-4 is typically sufficient.
The Takeuchi TB260 is a powerful and efficient compact excavator that, when maintained properly, can deliver outstanding performance on a variety of construction sites. GL-4 gear oil is a suitable choice for the TB260 due to its ability to provide moderate load protection, effective gear lubrication, and corrosion resistance under a range of operational conditions.
