SOURCE: I have a DeWalt DW927 cordless drill. It's lost

the brush assembly slides out of the back of the motor. I suggest going to and downloading a breakdown for this tool before starting. I don't think that the brushes are going to be your only problem though.

SOURCE: How to remove a chuck from a DeWalt hand drill

Open chuck all the way (like for a large drill bit). There should be a set screw at the bottom (where you would put a drill bit). Don't turn too hard - it may be a left handed screw (I don't remember if it is a lefty for sure but try gently each way then with a bit more force each way until it moves).

Good luck.

How to change brushes on a dc970

I don't think the motor is serviceable that way. At
DeWALT DC970 Parts List and Diagram eReplacementParts com you can find the motor and pinion for $35 plus shipping and then get the entire drill working again. Had the same problem with one of mine and it was an easy fix.

Dewalt 18v xrp clutch slipping and electrical smoke smell in rear

Yes you can. Depending on the model of the tool it may not be the clutch causing your problem though. On some models the transmission is more likely the problem. Brushes create an ozone smell when the motor runs so that could be the smell. Does it run slow or get hot?

Brushes over time will wear down so comparing from the old to new will not look the same. If 18V brushes fit into the your drill then it should be fine.

The drill was smoking while in use at the rear of the drill

Hi, these units tend to heat up over extended use. It is possible that your brushes have worn down and need to be replaced. The contact area around the commutator, (where the brushes push against), should be cleaned gently with ultra fine steel wool. Also, the gaps between the contact points of the commutator should be free of any conductive dust left behind by your dying brushes. Since the drill needs to be disassembled in order to do this, check any connections for weakness and any more conductive dust that may be shorting something. good luck.

My dewalt drill charger started smoking when i put the battery in although it wasn't even pluged in to the wall and now won't work

If this is for the 14 and 18 volt batteries, this is what I found had occured on one model I repaired (I've forgotten the charger model number):

It had a shorted diode (the bad one had obvious burn marks on the pc
board). I used an NTE 5809 diode to replace the original one. BTW you'll need
a Tamperproof Torx T-10 to open the case to access the pc board.
