Question about Drills
How do I DO IT
The screw might be a TORX but use the same procedure with a torx driver.
Posted on Jul 29, 2010
I work in a large shop and I do most of the tool repair. We do use DeWalt cordless guns so I have done this before. I change these as often as they break at work. About every 4 months the teeth fall out of a chuck and I replace the chuck with a new one. To remove this chuck you should use a heavy duty metric allen key and a good vise. The trick is to remove the small metric reverse thread screw. It is between 3 and 5mm. Place the "L" of the allen key firmly in the vise with the long end pointing straight up. Open the chuck all the way. Using a fully charged battery, place the gun in low (1st gear) and put the direction of the gun in FWD (as if you were driving a screw in), set the clutch to the drill setting (maximum torque) and drive that screw out of the chuck. If the battery is not strong enough to drive the reverse thread screw out you will have to help it out. Rotate the rear of the chuck clockwise and hopefully the screw will come out. If that is not enough torque, I find the use of a small strap clamp helpful to turn the chuck against the reverse screw. Hope this helps. Best Results! Michael Mittelsdorf
