I have a DeWalt DWD520 corded Hammer Drill. When I first purchased it, I was going to change the chuck myself but when I didn't see any reverse-thread screw inside the chuck, I was wondering how to remove it. Luckily, I took it to a DeWalt dealer and they changed the chuck for me without charge as part of the support.
Now that it is most likely out of warranty, I am looking at doing this myself. First & foremost, I want to say "Thank You" to Mr. C. Moore for posting that great photo of the chuck in the "disassembled view". I saved that picture as a reference.
What is crazy is that when I go to the actual DeWalt website, they actually list a reverse-thread screw for this drill!
I wonder why they did that...maybe to confuse the user into thinking that the screw is not visible, I don't know.
When I didn't see a screw, I thought, OMG....how the heck will I get this chuck off now?
I think I did try using a big allen wrench and hitting it several times with no success.
I am going to try using a Metabo drill chuck because it has a 3-Year warranty.
The only problem I might face is that I have a big masonry bit stuck in the chuck that won't come out because the clutches or gears inside the chuck seem to be "stripped out". When I try to hold the chuck and "bump it with the trigger a bit" to loosen the chuck, the chuck remains stationary while the motor shaft still turns. I might try to knock the end of the drill bit with a hammer to see if I can work it loose but since the inside of the chuck seems to be stripped, knocking it with a hammer and an allen wrench will be completely useless.
It might be time to break out the Dremel tool with the tiny cut-off wheels. Maybe I can cut it off carefully until I get close to the threads and then carefully split the rest of it until it breaks free. I would appreciate any feedback on this in case anyone else has experienced this same issue.
I'm new to the discussion here but I have actually worked in about twelve different trades before I retired.
