This is a genuine Dewalt replacement part, it is sold in a set of two. • Worn brushes frequently are the cause behind a motor running poorly. • Replacing brushes can fix a motor that's operating intermittently. • New brushes can restore a motor's electric braking. Carbon brushes are one of the most commonly replaced power tool parts. This is because carbon brushes are wear items, meaning that through friction and use they will gradually wear away until they need replacing. Worn brushes are a common causes of intermittent motor function, reduced electric braking and reduced motor power. A worn-out brush will often be worn down near to the wire lead and can be cracked, pitted, or burned. When replacing carbon brushes, be sure to inspect your armature for burns, cracks, or other damage which can indicate larger motor problems.

Great parts
In the first time came the wrong package but they resent it and reimburse my money. That was nice even though it took longer for me to fix my drill. Thank you

Good parts, fair pricing, quick turnaround
Always the best place to go. There are a lot of other sites, but I have had repeatedissued with them turning up on searches saying they have the part, but contradicting that fact when you actually get there, or worse, they notify you after you place the order that it isn't available - sometimes up to weeks later. Keep your inventory listing up to date and you can charge more for saving my time!

Fixed it.
The old brushes where so worn short that they no longer made contact with the commutator most of the time. It would not turn on without holding it at just the right angle or tapping it in just the right place. Put the new brushes in, and now it works fine. Very easy to do. Just needed two different star tip screw drivers to open up the drill/screw gun. The how-to video that ereplacementparts.com provided was spot on.
The "carbon brush and holder set" comes with the set of two brush assemblies. Each one of the two assemblies is different from the other. So ya, Part Number: N031214 comes with both bushes, as two pieces. One part as two pieces. I found that a little confusing.

The lower brush assembly is now ready for removal gently remove this unit by using a small screwdriver and pushing on it through the air exhaust slots on the outside of the unit. At this point you will need to clean the armature on the motor where the brushes make contact, because there is probably a glaze on this area. 3m Scotch Brite works well for this job. When reinstalling the motor assembly make sure the flat areas of the electric motor assembly are in alignment with the plastic drill case or the drill with not close back together correctly. Installing the brushes is easy just plug and play set up and reinstall your bearing caps and you are almost done. Reinstall all the torx screws holding the two case halves together and you should be good to go. Hope this helps.

Once brushes were install and wires fastened to brushes drill head and motor was put back into place (magnet for drill motor must be seated properly into case or bracket mount will bind the motor, rotate until you feel it seat in) once drill motor brackets are in and screws tighten, drill handle goes back on pretty easy just be careful if you have a handle guide light that it and brush wiring are back in proper grooves before closing the handle together and tightening screws! Would be a very easy repair to do again!
