Introduction to the Takeuchi TB035
The Takeuchi TB035 is a compact mini-excavator renowned for its versatility and reliability in various construction and landscaping tasks. Manufactured by Takeuchi Mfg. Co., Ltd., a Japanese company established in 1963, the TB035 model has been a staple in the mini-excavator market. Its compact size and powerful hydraulics make it ideal for urban construction sites where space is limited.
Importance of Hydraulic System Maintenance
The hydraulic system in the TB035 is crucial for the operation of various components, including the boom, arm, and bucket. Regular maintenance of the hydraulic system ensures optimal performance and longevity of the machine. One critical aspect of this maintenance is the replacement of the hydraulic filter.
Locating the Hydraulic Filter
The hydraulic filter in the TB035 is typically located near the hydraulic tank. For precise identification and location, it's advisable to consult the machine's service manual. The manual provides detailed diagrams and instructions specific to the TB035 model.
Hydraulic Filter Replacement Procedure

1. Preparation: Ensure the machine is on a level surface and the engine is turned off. Engage the parking brake and allow the hydraulic system to cool down.
   
2. Accessing the Filter: Remove any panels or covers obstructing access to the hydraulic filter.
   
3. Draining Hydraulic Fluid: Place a suitable container beneath the hydraulic tank. Carefully remove the drain plug to allow the hydraulic fluid to drain completely.
   
4. Removing the Old Filter: Using an appropriate tool, unscrew the old hydraulic filter. Dispose of the old filter and fluid according to local environmental regulations.
   
5. Installing the New Filter: Lubricate the rubber seal of the new filter with a small amount of clean hydraulic fluid. Screw the new filter into place by hand, ensuring it is snug but not overtightened.
   
6. Refilling Hydraulic Fluid: Replace the drain plug and refill the hydraulic tank with the recommended type and amount of hydraulic fluid.
   
7. Testing the System: Start the engine and operate the hydraulic functions to check for proper operation and to ensure there are no leaks.
   

Recommended Hydraulic Fluids
For the TB035, Takeuchi recommends using hydraulic fluids that meet the specifications of TDTO (Takeuchi Drive Train Oil) or equivalent. It's essential to use the correct fluid to maintain the efficiency and longevity of the hydraulic system.
Common Issues and Troubleshooting

• Slow Hydraulic Response: This can be caused by a clogged hydraulic filter, low fluid levels, or air in the hydraulic lines. Regular maintenance and timely filter replacement can prevent this issue.
  
• Hydraulic Leaks: Leaks can occur due to worn seals or loose fittings. Regular inspection and maintenance can help identify and rectify these issues promptly.
  

Conclusion
Regular maintenance of the hydraulic system, including timely replacement of the hydraulic filter, is vital for the optimal performance and longevity of the Takeuchi TB035. By following the manufacturer's guidelines and using recommended parts and fluids, operators can ensure their machines remain in excellent working condition.
