How to Separate Glass from the Door Frame of a Takeuchi TB260

[MikePhua]

Introduction
Over time, the glass in the door of construction machinery like the Takeuchi TB260 mini-excavator can become damaged, requiring replacement or maintenance. One of the first steps in this process is separating the glass from the door frame. This guide will walk you through the necessary steps to safely remove the glass without causing further damage to the door assembly or the surrounding components.
Tools You Will Need
To begin, you will need the following tools:

• Flathead screwdriver or pry bar
  
• Rubber mallet (optional)
  
• Safety gloves and goggles
  
• Replacement seals (if necessary)
  
• Silicone lubricant (optional)
  
• Small ratchet and socket set (if screws are involved)
  

Step-by-Step Process

1. Preparation and Safety First
   Before starting, make sure the machine is turned off, and if necessary, the battery is disconnected to avoid any electrical issues. Wear your safety gloves and goggles to protect yourself from any sharp edges or glass shards.
   
2. Removing the Door Frame Seal
   Most doors on machines like the Takeuchi TB260 have a rubber seal or gasket that holds the glass in place. Start by gently prying off this seal using a flathead screwdriver or pry bar. Be careful not to damage the seal if you plan on reusing it. Work around the perimeter of the frame to remove the seal completely.
   
3. Loosening the Glass
   After removing the seal, check for any screws or bolts that may be holding the glass in place. Some models use screws or fasteners around the edges of the door frame to secure the glass. Use a ratchet and socket set to remove these fasteners, if present.
   If the glass is still held in place by adhesive or sealant, you will need to carefully loosen the adhesive using a flathead screwdriver. Start from the corner and gently work your way around the edges of the glass. In some cases, the glass may be adhered quite strongly, requiring some force to break the seal.
   
4. Removing the Glass
   Once the glass is free from fasteners and adhesive, gently lift the glass out of the frame. If it’s stuck, tapping around the edges with a rubber mallet can help loosen it. Make sure to support the glass as you remove it to avoid any sudden shifts that could cause breakage.
   
5. Clean and Inspect the Frame
   After the glass is removed, clean the frame thoroughly to remove any remaining adhesive, sealant, or debris. Inspect the frame for any damage, rust, or areas that may require touch-up before installing the new glass. If needed, apply a little silicone lubricant to the frame to help with the new glass installation.
   
6. Installing New Glass (Optional)
   If you’re replacing the glass, ensure that the new glass is the correct size and shape. Place the new glass into the frame and apply a new rubber seal or gasket. Secure the glass by either tightening the screws or applying adhesive, depending on the design of your machine. Ensure everything is sealed tightly to avoid future issues.
   

Conclusion
Separating the glass from the door frame of a Takeuchi TB260 is a manageable task with the right tools and careful technique. By following the proper steps, you can successfully remove and replace the glass or repair any issues with the door assembly. Always take precautions to avoid damaging the frame or surrounding components, and ensure everything is reassembled correctly to maintain the integrity of the machine.
