Installation notes
Take out the drill battery. Look inside the open chuck for a retaining screw and remove it (left-hand thread: turn clockwise). Chuck a short hex key tightly, then give it a sharp tap with a hammer to spin the old chuck off the spindle. Clean the spindle threads and screw the replacement chuck on hand-tight, then snug the retaining screw. Spin a bit to check for wobble.
Common questions
Q: Will the N092054 keyless chuck with chuck screw fit my DeWALT DCD771C2, and does it also work on the DCD780B and DC970K-2?
Yes, this chuck is compatible with the DeWALT DCD771C2, and it is also listed to fit the DCD780B and DC970K-2 models. If your original chuck on one of those drills is damaged, slipping, or no longer tightening properly, this replacement is the correct style for those model numbers.
Q: Does this N092054 replacement chuck come with the center screw, and how do I install it on my DCD785C2?
Yes, this part includes the chuck screw, which is the retaining screw used inside the chuck. To install it, open the chuck jaws fully, remove the old retaining screw from inside the chuck, then remove the old chuck from the spindle and thread the new one on; make sure the retaining screw is reinstalled securely so the chuck stays tight during use.
Q: My DeWALT DC725B chuck still opens and closes, but it won’t hold bits tightly anymore. Will replacing it with the N092054 fix that, and is there any maintenance I should do?
If the jaws are worn or the chuck keeps loosening on bits, replacing it with the N092054 is usually the right fix for a DC725B. For longer life, keep dust and debris out of the jaws, avoid overtightening with excessive force, and check occasionally that the chuck screw remains snug inside the chuck.
