No, the brushes are part of the motor and pinion, Dewalt part number 607990-03. If you search "dewalt 607990-03" you can find several on-line vendors that sell the motor. They run about $50 plus shipping.
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.
Hi there, the first thing you need to do is check the carbon brushes, there will be two of these one at each side of the motor, if these are ok then test if power is getting to the motor, to do this you will need to split the casing on the tool in half. You may need a torx driver to undo the screws on the casing. Once you have removed the screws, very carefully split the casing making sure you leave the gearbox assy, motor and switch in the other half. Insert battery onto the unit and get someone to hold the motor in place just incase the machine starts. get a voltmeter, follow the wires from the switch to the motor and where the wires attach to the motor put the probes of the voltmeter and pull the switch to engage it. You should be gettting a good voltage now, If you are then the switch is ok. hope this is of some help
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.
It depends on what you mean by intermittent. If the drill takes a few tries to turn on, but works fine once it does, it usually means there's a problem with the switch. If the power is weak and tends to cut out, it generally means there's a problem with the motor - usually brushes. This article might clear things up a bit:
some models have external brushes for easy changing - when the brushes wear down you can easily change them for new ones, some models have this feature ,it is only of use if you are using your cordless drill on a daily basis.
