I had to deal with a cracked and leaky valve stem on one of my tires, and I wasn't in the mood to break out the tire changer to break the bead and dismount the tire, so I decided to try out the AME 51025 Quick Valve Change Tool.
It definitely lived up to it's name.

The general idea is that you push in a hook and pull out the damaged stem, before using a funnel like tool, a gratuitous amounts of tire lube, and a plunger (for lack of a better term) to ram the new valve in from the outside.
Despite not being able to hook the valve stem to pull it out, I was able to cut the stem off and push a new valve stem through from the outside. Surprisingly fast and fairly effortlessly. Check out this video of my making the swap.
I ran into further problems afterwards, and ultimately I did end up dismounting the tire to seal the bead with some polyurethane to stop the bead leaks I found (7 in total). I was getting tired of fighting this tire over the past couple years and decided that essentially gluing it to the rim was going to fix this once and for all. If you want to see me using the tire machine, here's a previous video I put together a couple years ago.
