"Now I'm going to show you how to replace a water key spring. Usually water keys will break, just over time the metal gets brittle on them, or if you're hard on them and don't oil them properly, then they will wear out on you. But first of all, obviously this is broken, we're going to have to remove this pin here from there. And I've already chosen my new water key spring right here. Here's where that handy tool comes in.
