Electrical burn smell from rear of drill
Remove the four screws from the rear motor housing cover using a Torx bit. Remove the cover. Disconnect the lead wire from the motor and pry upward the brush assembly. Clean the area using air or some other means to remove the dust, etc. Insert the new assembly(s), connect the lead(s), remount the rear cover and you are ready for more productivity.

Hi rony,Try rotating the adjustment collar to 1 and try again.I should come out rather easy.
Hi Mr,the brush is a brush spring cartridge and you just gently pry them out.
Question: New Transmission Won't Slip!
I put in a new transmission in my dewalt dc920 because the old one would slip with very little resistance, regardless of the clutch setting. Now the new one doesn't slip at all - even if I put the clutch on position one, it will not slip as it should. I reinstalled the transmission several times, making certain it was installed properly.
Question: Transmission Assembly
I have a DeWalt DC920 18V Cordless Hammer Drill/Driver. The Transmission jammed. I took it apart and cleared the jam. But when I was putting it back together, some of the transmission gears fell out. Now I don't know how it goes back together. Do you have instructions and a diagram showing how to reassemble the transmission?
Question: Drill Thats Burning Out Batterie...
I have an 18v DC920 xrp drill and when I stick a battery in the drill it starts to burn out the battery. I had four batteries between my drill and air gun, now I'm down to one. Help me!

It sounds like your variable speed switch is shorted. I had this happen twice.
How do you replace the brushes on a dc920 dewalt drill driver?
You can access the motor by removing the rear cap on the drill. The brushes are held into the motor by two clips on each of the brush holders. remove the old brush holder by bending the clips back and pulling the holder out. The new holders will snap into place. The brush and holder is part #603754-01 and is available from http://ereplacementparts.com.
Good luck with your repair!
Question: Dc920 Dewalt Locked Up
I work at a manufacturing plant, and we use a lot of dewalt tools. From time to time, I help out in the toolroom when I am caught up on my office work. They have a drill that was brought in that was #1 overheated, which led to it locking up I assume, because now the drill is locked up.
Any help would be appreciated.
Reply: Dc920 Dewalt Locked Up
If the drill did overheat and motor stinks, the armature and brush holders have seperated and the can motor needs to be replaced. If the motor did not heat up your problem could be in the gear box.
Pull the can motor and try to try the small gear on the end of it. If it moves then it might be ok. Hook it up to the switch and see if works ok.

thanks for the info.. I will do that.
Question: DW920 Transmission
I have a Dewalt DC920 XRP cordless drill. The transmission slips which tells me it's broken and needs to be replaced. This is the second transmission in this drill. Why does it keep breaking? Is it cheaply made with plastic gears? Is there a better quality transmission I can purchase with all metal parts? I'd pay double as long as it lasts. Is this a common problem with these drills?
my 18v dc920 drilll driver will not run in low gears correctly when load is put on it clutches any help would be great

Question: Keyless Chuck Problems
I have a DeWalt dc920, does this have a threaded shaft to remove the chuck, or is it pressed on, any info will help
Reply: Keyless Chuck Problems
The chuck on your DC920 is mounted on a threaded spindle. It's pretty easy to remove if you use the right method. Here's some more information on chuck removal:
Question: Brushes For DC920?
My friend says his DeWalt 920 18vt drill will be running but will then stop. If the trigger is still depressed, it can then be started again if he will manually twist the chuck. Is this drill in need of brushes? He just put a new switch in it a month ago. I believe the tool is about 2 years old or better.
thanks for any help.

Time for some new brush's..or look for a loose connection on the brush holder..worst case is the motor has an open in the armature and needs replaced..but check out the brush's first..
Hope this helps..!

Thanks for the reply. I got the drill back today and pulled the brushes out. That's the problem, they are shot. I ordered the replacements moments ago:)
Question: DeWalt Cordless Drills
Is it just me or does DeWalt have a bunch of sorry products (cordless Drills). The forums I read is full of problems....I've e-mailed DeWalt several times regarding my drills....they don't even respond. I have a DC920....I've had to replace the switch...now the chuck "dogs" are not even with each other. I'm working on that problem....looks like I might be able to fix. My son gave me complete kit....Hammer drill, circular saw, recept saw, etc. The hammer drill, DW988, throwing sparks and smoke from the brush end...pulled out the brush holder, cleaned up everything....no link removed will have to replace motor......I really think DeWalt has chuck and VSR trigger problems and they won't back up their product. I'll think twice next time......vernarooskie
Reply: DeWalt Cordless Drills
For sure, every brand has its gremlins. Personally I haven't heard of more problems with Dewalt cordless tools over other brands. Over time any switch will wear out, but as for the motor, I do hear of a lot of people overworking their cordless drills (mixing mud, running 3" hole saws etc) which can cause a lot of problems. That may or may not have happened here. Of course Dewalt doesn't make their cordless drill chucks, but if I remember correctly that Jacobs chuck on the DW988 wasn't the best. Their new Rohm chuck is pretty impressive though.
