I found an easier way to remove chuck: I put a vicegrip on bottom of chuck and hitted down with a hammer a few times and came off within a couple minutes.
Here's a small tip for free to get that chuck off in 30 seconds. Get a 10 mil Hex Key and put the long side in the chuck and tighten it as far as you can, tap down on the short end rotating it after every tap and the whole shaft and Chuck will come out of the drill with no damage to the drill or chuck
My DCD791 has a retaining plate on the shaft with six small screws that fixes the shaft to the transmission housing. There is no way that shaft is going to just pop out like this. The important take-away for me is that the chuck is a normal, not reverse thread.
had to use plumbing pliers to get the bastard to let go of a bit, took 4 hours of trying all sorts, then when putting new bit in it sliced my finger on a freshly created metal barb -.- damned things only 14 months old but I have just put a thousand long screws into a refit and structural fix on the kitchen so I guess I murdered it :).
Hello . I am in the process of replacing it, but during disassembly the cables came out of the connector and I don't know what colors and what. one connector is black and red together and the other plug is black and blue. should black go to black and blue to red? please give me a hint
Witam . Jestem na etapie wymiany ale w czasie demontażu z kostki wyszły mi kable i nie wiem jakie kolory co do czego . jedna kostka czarno czerwony razem a druga wtyczka czarno niebieski . czy czarny ma iść do czarnego , a niebieski do czerwonego . proszę o podpowiedz
I would be very carefull removing the pin that the chuck screws onto.. Theres bearing behind the housing that wont come out with the pin, By forcing the pin out of the drill, you will have slid the bearing and hammer drill teeth off the shaft, The drill might get stuck in hammer mode with no way to release it.. That happened to mine.. Very very difficult to fix..
I just watched your other video, but you still havint fixed it.. If you look at the back of the chuck, it is still sitting too far away from the drill which means the hammer drill teeth and bearing are not fully seated down the pin shaft.. Look at the exploded parts diagram for the 796 and you will see where the splined teeth, spring washer and bearing are permanently friction fit to the shaft.. You have to do that first otherwise the drill will not go back together correctly..@@powertoolsrepair
No problem.. Its a really annoying drill to repair.. I was determined to fix mine, it was only a few weeks old, but the chuck was really bad from factory.. It took me a while to figure out that the hammer teeth had came off the pin, thats why it is so difficult to knock the pin out..@@powertoolsrepair
@@petrokemikal Yes, I had the same problem with a stuck hammering, the fix is not difficult, you just need to change the procedure for installing the new chuck. After unscrewing the old chuck from the axle you need to loosen the round cover that is under the chuck (3 screws), under the cover is the bearing, washer, spring and shaft. It is necessary to take the cover to put the bearing in it and push the axle through (be careful not to forget the spring under the chuck), then you need to take the shaft and bump it all the way to the end of the axle, I chose the procedure of heating the shaft on a hot plate so it jumped in easily after a little tapping. Then you need to put back the spring and washer and screw the cover back on (3 screws). Finally, all that's left to do is spin on a new chuck (with the axle already installed in the drill). Hope this makes someone's day easier.....

Nice one, will try it next time

Thank you, I have tryed this way,but no luck several times, but maybe chuck was tightened to hard
Are you sure that you're supposed to rip the shaft out like that? Seems like a great way to trash the tool.
Yes, its one of the way to replace chuck

Chuck must be normal thread, reverse thread is screw inside chuck. All DCD791 I have repaired had same gear assy as in video

Yes you murdered it 🙂 and its a reason to use gloves 😅

Same happened to me and I made next video on reassemble of gear assy to fix that

@petrokemikal thank you very much, I don't have that drill now but I will make sure I do that when I will repair next same drill. Thank you

No wonder the chuck never gets loose.
