Fred swigs a 12-pack of Bass Ale onto the table

I have a couple of cheap drill chucks that feel like they've been lubed
with a mix of rubber cement and swarf. Just soaking them in solvent then
relubing might work but taking them apart would let me look for burrs.
After guessing that they are assembled with a right-hand thread between
the top part (with the taper hole) and the lower part (with the 3 holes
for the key) I tried a judicious use of force and saw no movement at all.

Before I employ a meticulously calculated lever arm (which happens to
match the length of my largest wrench) and an oh-so-gentle tap of a BFH,
could anyone tell me if this is how they are supposed to come apart? I'd
appreciate it; the chucks would appreciate it; so would my wife, kids,
and neighbors.

I have just taken a hacksaw to the cheap drill chuck that came on the cheap
drill press and that seems to be the olny way to take it apart.

The brand name is San Ou, and the body looks like it has a black-oxide
finish, contrasted with the ground finish of the other parts.

It's not like a real jacobs chuck. The "body" is made of sheet metal which
must have been pressed around the toothed ring to grip it, and I think it
was rounded over at the base of the chuck where the female taper is.

The jaws on mine had many breaks in the teeth; the broken bits were mixed in
with the grease, and it was a total loss - I suspected that was so when I
decided to go the hacksaw route, and a local hardware place has jt33 chucks
on sale, so I'm off to have a look.
