Hi Greg, I have a couple of Albrecht drill chucks and the knurled bit in the middle just screws off. I say just screws off you may need to use a strap wrench on the knurled bit and a 'V' block in the vice to hold the body.
It is best done with the jaws full open or fully closed sorry Greg I can't remember for the life of me - so try half way.

PS According to the Jacobs repair that Ed posted the chuck jaws need to be fully closed.
