What opens up dewalt drill to change brushes - Dewalt 18v Battery Hammer Drill Dcd950 Dc925

I don't know. Dewalt does not see the brushes separately, by the way. The brushes are included with the part number 391886-01SV Motor and Pinion, purportedly.

Don't know if calling Dewalt would help. https://www.dewalt.com/support/


Here is another link which may prove to be totally useless to you but is included just because I don't know if it might offer a hint or not:

tight bearing maybe

The brush holders & brushes for your DC825 are only sold as an assembly and the left and right sides are different; Dewalt part number 640550-00 for the left, 640555-00 for the right. They are accessable only by splitting the clamshell and easy to replace once you get to them.

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.

Test the brushes by catching it in a stalled condition when you have it triggered, then rotate it slightly. If it takes off suspect the brushes or a dead segment on the comutator.

If it doesn't respond to this, then consider the VSR trigger... open it and test by bypassing it when in stalled condition...

you cant replace the brushes on this drill it is a sealed motor. go this site the replacement motor is $ 38.77 http://www.ereplacementparts.com/dewalt-dc759ka-type-18v-cordless-drill-parts-c-1009_

They all do that a bit. The sparks when starting up and stopping are normal. If it has been used alot brushes may be a good idea but before they need to be changed it will spark quite a bit.

It will not hurt to inspect the amount of brush material remaining.

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

yes,the most coomon defect for poer tools are carbon brushes.But,git attention also to the gears,bushings, and bearings if there are loosen parts.Also you get rid to a debris or any small dirt particles that maybe sunctioned by the fan and has been entered in the body of the drill thats why you can hear an squealling noise..Just open and clean it.

Some cordless Dewalt drills do not have open motors allowing access to the brushes. However there are a few styles that do.

If you want to check, open your drill. Remove the screws from the housing. Then remove half of the housing. You can see the motor at the back of the tool. If there are vents at the back of the motor you may be able to see the brushes the removable type are connected to a gray or tan piece of plastic mounted at the back of the motor.

If the brushes are from a removable style you can purchase a brush set. If they are hidden in the motor. You will have to change the whole motor.

You can check the Dewalt Service Net web site to find out.
