He returned it and I put it away. Yesterday I pulled it out and as soon as I pulled the trigger a small amount of smoke comes out of motor area and smells. It works tho Are the brushes bad? Seams to spark a lot near amrature. Gotcha Well-known member. I pulled and cleaned the brushes on mine in November. They were chipped and generally nasty. There's a lot of grease around there, could just have been used at an angle you haven't before and got goobered.
Good excuse to buy a new tool and see what the old guts look like. If you can service the motor I would take the brushes out, inspect the copper segments on the commutator for burnt spots, clean the commutator lightly grind with a comm. I personally haven't fixed the DeWalt drill motors, but I have replaced a few drill motors at work that industrial maintenance guys abused in the steel foundry.
Also, I intend to get both my girls small drills when they're 8? My 4 year old drilled and hammered dowels on the bunk bed she sleeps in, hoping to have them able to repair their own cheap furniture and basic plumbing before they go.
DBendr Banned. Joined Dec 30, Messages I just went through my old 18XRP and it still did the same minus smoke. As the carbon brushes wear down, they can spark more. This can cause a heavy carbon build up between the brushes and the commutator, causing the drill to smoke.
To fix this, you will need to replace the brushes and clean the commutator, which will vary slightly on drills. As mentioned at the beginning of the article, the numbers on a drill represent the amount of torque the tool can apply to an object such as a screw or for hole drilling. The numbers usually range from 1 to 20 or more with 1 representing the least amount of torque and 20, the greatest.
In simple words, the numbers on your drill refer to how much torque will be applied to a fastener such as a screw. Take the motor and transmission assembly out of the housing and separate the motor Take the motor and transmission assembly out of the housing and separate the motor from the transmission.
If the motor is sealed, throw it out and replace it with the proper one for your model. Find your Motors here.
The switch provides power to the motor when pushed. If the switch has become worn, it can short out and produce smoke. Signs that a switch is going bad will occur when the drill begins to not work every time, when pushed.
This will eventually worsen with use, to the point where it can smoke. Remove the end cap on the drill. Next, remove the two screws holding the transmission to the motor on the side of the transmission where all of the housing screws are facing upwards on the case, securing it to the housing.
Remove the screws securing the two halves of the case together and separate the halves. Remove the other two screws on the transmission that secure it to the motor. Remove the screws securing the hold-down brackets on the motor and then the motor and transmission assembly.
Remove each wire from the brush holder and Remove each wire from the brush holder and do not mix up where they originally attach. Remove the switch from the drill. Inspect the inside of the switch for burn marks. This will indicate it is shorting out or has completely shorted out. The switch will need to be replaced as it cannot be repaired. Install the new switch into the housing and reattach the wires to the correct brushes.
Now, insert the brushes back into the drill housing, ensuring all wires are tucked into the wire channels. Reinstall the motor and transmission assembly back in the drill housing. Reattach the hold-down brackets and secure them with the screws. Reinstall the two screws securing the transmission to the drill case and then the second brush holder into drill. Put the case back on the housing, followed by the other two screws securing the transmission to the motor. Find your Switches here.
The holders hold the brushes in place on the commutator. If the holders are damaged, they may not be able to hold the brush in the proper position on the commutator, with the correct pressure.
This can cause excessive sparking leading to a smoking tool. On some drills, all that is required to reach the brushes and holders are simply to just remove the end cap. On other drills, you will need to carry out the following steps. Remove the two screws holding the transmission to the motor on the side of the transmission where all the cover screws are facing upwards on the housing, securing the case to the housing.
Next, remove the screws securing the cover on the housing and remove it. One of the brushes is located on the cover. Remove the holder from the housing. Take out the screws Take out the screws securing the hold-down brackets on the motor and lift the motor up and remove the other brush holder.
Inspect both brush holders for damage and wear on the brushes and replace as needed. If they are in physically good shape, then clean thoroughly. Reinstall the one brush holder back in the housing, ensuring it is in all of the way. If the brush holders are not all of the way in or positioned a little out of alignment, it can cause the problem to continue. Reattach the wire and then reinstall the motor and tighten down the brackets.
