cirial Posted August 14, 2011 Report Share Posted August 14, 2011 New here.. Needed to replace my chuck on the DCD950 and this video is invaluable. How much loctite do I use (on all threads, just at the bottom..), and should I get the red or blue loctite? Also, if I dont have a mallet when hitting the allen wrench, would a hammer be just as fine? Quote Link to comment Share on other sites More sharing options...
kanxrus Posted August 15, 2011 Author Report Share Posted August 15, 2011 A hammer would work fine, just don't put a lot of force behind it. Use the red loctite, and apply a lite coat on the first few threads. Quote Link to comment Share on other sites More sharing options...
jconradh Posted September 27, 2011 Report Share Posted September 27, 2011 Quick question: I have read the Rohm chuck should never be opened or closed by using the drill itself, rather only hand-tighten the chuck with the spindle locked. Is this true? I never had a problem with my DC927 chuck until I lent my drill to a friend and he used the drill motor to tighten the chuck onto a bit. Afterwards the chuck would lose it's grip if I tried to free a stuck bit in reverse. Never had that issue prior. Now I have bought a 700 Jacobs chuck to replace the old Rohm, and I won't lend out my $300 drill again. Thanks, Jeff Quote Link to comment Share on other sites More sharing options...

I will not go so far as to say what is the proper way to use it, but I always (as in EVERY time) use the motor to tighten or loosen my chuck.

kanxrus Posted September 28, 2011 Author Report Share Posted September 28, 2011 I have several Dewalt cordless drill that all have the Rohm plunger chuck, and I always us the motor to tighten and loosen the chuck. Where did you hear this from? Quote Link to comment Share on other sites More sharing options...
jconradh Posted September 28, 2011 Report Share Posted September 28, 2011 From the DC927 owners manual: "Self-Tightening Chuck Operation (Fig. 5–7) WARNING: Do not attempt to tighten drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result. Always lock off trigger switch when changing acces sories. WARNING: Always ensure the bit is secure before starting the tool. A loose bit may eject from tool causing possible personal injury." p.s. The new Jacobs 700 series chuck works fine. When it fails I may try the Rohm again.

kanxrus Posted September 28, 2011 Author Report Share Posted September 28, 2011 HA! Well I guess we all learned something today! That being said, I probably won't follow those instructions Quote Link to comment Share on other sites More sharing options...
cirial Posted January 5, 2012 Report Share Posted January 5, 2012 Dewaltdude.. so I had applied loctite and installed the Rohm chuck on my DCD950 back when I asked a couple questions in this thread. Fast forward to yesterday at work, I'm using it to try to take out a 4 inch phillips head screw that is in a concrete wall. I put my drill on drill mode, highest clutch setting on gear 1. The screw didnt move, I stripped it a little bit and then after a quick second my chuck fell off! What am I doing wrong here? I just redid the installation last night and applied a very liberal amount of loctite this time. Used a hammer and wacked the allen key real good.

kanxrus Posted January 5, 2012 Author Report Share Posted January 5, 2012 What kind of loctite did you use? I used the LOCTITE THREADLOCKER RED 271. Quote Link to comment Share on other sites More sharing options...
cirial Posted January 6, 2012 Report Share Posted January 6, 2012 I got this stuff at Discount auto parts.. Permatex Threadlocker Red. Wonder if it's just crappy. I put it on the last few threads closest to the inside of the threaded spindle the first time I installed the chuck. This time I put significantly more on the threads so I will see what happens. Bottom line it should never come off no matter how torqued a screw is in right? Quote Link to comment Share on other sites More sharing options...
kanxrus Posted January 6, 2012 Author Report Share Posted January 6, 2012 Correct, it should never come off. Make sure the loctite has a few hours to set before you touch it. I let mine rest inside the house where it was warm for 24hrs just to be safe. Quote Link to comment Share on other sites More sharing options...
tooljoe Posted January 7, 2012 Report Share Posted January 7, 2012 my suggestion is to grind a little off the tip of the screw... my guess would be that the screw is a hair too long and not allowing it to tighten down... that or add a washer, with a big enough hole for the screw and small enough to fit in the chuck... IMO. EDIT: i just noticed that this chuck does not have a screw to lock it in. Quote Link to comment Share on other sites More sharing options...
cirial Posted January 8, 2012 Report Share Posted January 8, 2012 @tooljoe, thanks for the suggestion but this is the stock chuck for the DCD950. @dewaltdude, I let the thread locker dry the first time I installed it for a few days. However at that time just applied a small amount on the base of the spindle where the chuck attaches. Used the drill only a handful of times before it fell off trying to extract a rather stubborn screw from concrete. Now that I've applied a rather liberal amount of thread locker red to the threads and it's dried for several days I may go back and see if I can get that screw out without it falling off again... What a headache! Quote Link to comment Share on other sites More sharing options...

Yes it does exist in some manufactures key less chuck ,Metabo chuck does this to prevent the chuck from destroy it and you must then open the key less chuck removing the safety clutch behind the chuck and loose the chuck.
