Hi. open the chuck to the max. inside the chuck you will see a screw. remove it. put the drill in reverse. hold the chuck. a vice may be needed. pull the trigger. this may work, however in my experience, they are very tricky to get off. I have never had a faulty chuck but have had many faulty gearboxes. i have had to buy ney chuck to fit with the new gearboxes because i couldn't get the good chuck of the damaged gear box. good luck.

Open the jaws of the chuck all the way open. Inside the chuck you will see a slotted screw. Use a large flat head screw driver and remove screw. It will have left handed threads.
After you remove the screw put the end of the chuck in a vise where the 6 flats sides are. Put the drill in low gear and reverse. Hold tight and turn on the drill. This should run the chuck right off the spindle.
