Yeah, real simple. All you need is a variable speed hand drill and a rubber mallet.
- pop one end into the drill so that the vale is far in as it will go.
- then rotate the valve untill you see where is off-center, then gently wack the top with the mallet in the opposite direction, rince & repeat untill its centralized.
- remove the valve and put the other end into the drill as per steps, 1 and 2.
