To remove the chuck, insert the proper screwdriver into the chuck to remove the screw at the bottom. Snug the chuck against the screwdriver and loosen by turning it clockwise (this is reversed thread). Once you’ve broken the tightness of the screw, loosen the chuck and continue to remove the screw.

To remove the chuck, insert the proper screwdriver into the chuck to remove the screw at the bottom. Snug the chuck against the screwdriver and loosen by turning it clockwise (this is reversed thread). Once you’ve broken the tightness of the screw, loosen the chuck and continue to remove the screw. With the screw now removed, insert a big allen key into the chuck and tighten firmly, then insert a pipe over the allen key for leverage – turn counter clockwise to loosen the chuck.
A second method is to hit the allen key quickly with a hammer to loosen. Once loosened, continue to remove from the spindle. Thread the new chuck on the spindle. Next, open the chuck and insert the allen wrench and hand tighten the chuck. Reinstall the screw, remembering it is reverse thread, and tighten.
