This is how I remove sealed cartridge bottom brackets. Removal in seconds. They can often be very tight, or even stuck/frozen/seized, but this method has always worked for me. And with the downward pressure, I get a good connection and am less likely to strip the notches/splines in the cup and tool. I used a Kawasaki 1/2″ corded impact wrench. What’s more fun than power tools? The bottom bracket tool I used was a Pedro’s Bottom Bracket Socket: https://www.amazon.com/exec/obidos/ASIN/B003FPXLO4/ref=nosim/youtube25-20
And yes, I am aware the frame is damaged on the chain stay, so that is why I am stripping the parts from it.
