Restoring the Fuel Tank on a 1991 Yamaha RT180 Dirt Bike (Part 2)
Soldering and Tank Lining.
Welcome to part two of our fuel tank restoration series for the 1991 Yamaha RT180 dirt bike. In this video, we tackle soldering the holes in the fuel tank and explain the differences between soldering and brazing. This is a new experience for me, and I invite you to learn alongside me. Hopefully, this will encourage you to try it out, even if you have no prior experience.
The process involves balancing the soldering with the final steps of removing flash rust and evacuating dangerous, flammable gases from the tank before turning on the torch. It's a careful and challenging procedure, but we manage to do it safely!
Here's what you'll see in this video:
• Encountering a scare with thunder outside, thinking something went wrong.
• Ensuring there are no flammable gases in the tank.
• Explaining the differences between soldering and brazing, and using solder that melts at about 450°C.
• Using a soldering kit from Home Depot (Oatey brand, part 506912) and demonstrating the soldering process for the first time.
• Dealing with impurities, heat marks, and flash rust during the soldering.
• Checking the tank for leaks and ensuring it's solid and leak-free.
• Neutralizing the tank with baking soda and water, followed by rinsing and drying it with acetone.
• Handling the tricky process of drying the tank without causing flash rust.
• Pouring in the Kreem-branded tank lining product, tilting, and twisting the tank to ensure the liner coats the entire inside.
• Rotating the tank multiple times and allowing the liner to dry properly.
Join us on this journey as we overcome obstacles and successfully line the inside of the tank. The final result looks fantastic, and we're one step closer to getting this classic dirt bike back on the trail!
