Dewalt drill issue with Clam conversion kit

[MikeG3Boat]

Issue I am having is I can't get the chuck off my dewalt drill in fact I think I have broken the chuck.

I have removed the left handed thread screw from inside the chuck no issue there, but then the problems started. I initially put a Allen wrench in the chuck and pounded on the Allen wrench nothing is loosening. I then opened up the chuck fully and then took a large channel lock ply-ers and tried to twist off the chuck as I did this something snapped and I thought I got it, but no dice. The chuck now doesn't open or close. The outside sleeve on the chuck just spins both ways and does nothing but spin. So the end of the chuck can be griped with a 3/4" socket, so I then tried using my impact wrench to try and remove the chuck, again no dice. I had to stop working on this before I lost my cool. Does anyone have any suggestions of what to try next? I am at a loss.....

Help please!

Thanks guys

If you can still get a bite on the chuck with a socket try putting the ratchet in a vice or clamp it to a bench and applying the pressure to your drill as opposed to the wrench. I had to apply pressure to my drill and dead-blow it with a rubber mallet to get it to break free. The sudden hit with the mallet did it for me. Start soft and gradually step up the force of the mallet as needed so you don't break the drill.

I too had a mess with my DeWalt. Took me about 2.5 hours to get mine off. During that time I also was at the same spot where the chuck wouldn't close. I eventually got the chuck back working and the eventually got it off by putting the big allen wrench back in the chuck. I then put the allen wrench in a vise. Slapped the drill with my hand and it was able to pop the lock tight free. DeWalt must have the best lock tight ever. Once you do break the lock tight it does come off easily. Sorry, not much of help here but just keep your cool and you'll eventually get it.

don't worry, it took me 4 days to work the drill issues out, but in the end all well worth it.

yes, most info tells you to put allen wrench in chuck and bang on allen wrench, for some reason this does not seem to work with dewalt as much. try and get allen wrench in chuck and I think for dewalts gently hitting the drill handle works better than trying to turn the allen wrench, I tried many times allen wrench solid in vice grip and hit that with no dice, then allen wrench stuck in bench vice and used rubber mallet on drill handle and presto! but sadly you will probably need more force than you think you do, that does seem to be a common denominator

1st problem was removing the chuck. Following the many instructions posted on You Tube, I was unsuccessful. However, I finally removed the chuck using the following technique: 1st, to remove the internal locking left handed screw, I put the screw driver in a vise, set the drill to low speed power, and powering it in the clockwise direction ( drilling direction) while holding the drill with two hands to remove the screw. Next, I chucked a large Allen key and mounted it in a vise, setting the drill to low speed power, and powering it in the counterclockwise direction (removal direction) while holding the drill with two hands to remove the chuck. If you still cannot remove the screw or chuck , you may want to heat the assembly with a heat gun to soften the Loctite material.
