My PC Model 9984 19.2V cordless drill has done me dirty and only growls
at me whenever I try to use it. Thought it might be the clutch or the
gearbox so I have taken it apart to do a little diagnosis. I found the
LH allen screw buried in the mouth of the chuck and removed it. I
cannot separate the gearbox from the chuck for love nor money however.
I thought the chuck might be threaded as well, but the parts diagram
from PC does not show this, nor any other retainer.
Anyone ever tackle this and come across the trick for removing the
chuck? Seems today is a good day for posts regarding drill chucks ...
It is threaded on right hand threads so clamp an allen wrench in the chuck
and hit it with a hammer or use an impact wrench and an allen socket Good
luck.

What I have never seen covered is what to do when you remove the screw
but still cannot remove the chuck, as in my case with a Makita cordless?
I'm not about to put heat on it and WD40 did not help. TIA
This has been covered many times before.
You already have removed the left hand threaded retaining screw.
Good
Close the jaws of the chuck on the small end of the largest right
angle Allen wrench you own. Borrow one from a neighbor if you
have none. Looking at the nose (looking where the drill bit would
go) turn the chuck counterclockwise. The way to turn it is to
strike the handle of the Allen wrench as hard and sharp as you
can. You have to really smack it, you may need to smash it
several times. It will unscrew once you get it started.

Can you still charge the batteries and make the drill run?
Open the jaws of a heavy vise. Do not close the vise on the Allen
handle, but make sure that the handle will bang into the vise jaw.
Let the handle swing as far as possible before hitting the vise
jaw. Make sure the drill is in low gear and reverse. It may
still require hitting the jaw several times. Having confidence
that the chuck will unscrew may be half the battle.
I always remember my dad's question whenever I asked for help to
fix something:
"well, it's not working now is it? I guess we can't hurt it
much!."

Well this turned out to be a tad tougher than I imagined it twould be.
The chuck and gear box are out of the drill. The gearbox is likely
toasted which is why nothing happens when I try to drill. The chuck is
impossible to unwind from the gearbox without any resistance somewhere.
I really did not want to have to replace both but unless someone has a
better idea ...
