It is difficult to remove the old chuck. I found penetrating liquid and sitting overnight to be helpful in getting it off.

2. Put some penetrating fluid near where the chuck screws in and let it sit for a good while.
3. Insert short end of the allen wrench into the old chuck and tighten as much as possible.
4. Holding tool down, use a rubber mallet to strike the allen wrench to unscrew it in the counterclockwise direction. Be careful not to damage the tool here.
5. Screw on the new chuck.
6. Apply medium thread locker to the retaining bolt and screw it in COUNTERCLOCKWISE to tighten.
