Thank you so much, using paint thinner actually worked, I used the paint thinner that is used to thin down polyurethane paints, but I didn't put the whole motor in it cuz I was worried it would remove the enamel coating on the motor winding, I filled a small cub with paint thinner and lowered the bottom part pf the motor in it for a few minutes, the paint thinner turned from clear to black , repeated the process after replacing the thinner till there was no black residue left, put it back together and it worked it lower speed fine but then when pressing the switch all the way it smoked again, so left it running for a minute on low speed and it stopped smoking and back to normal, failed attempts: tried contact cleaner first before disassembling the drill, that didn't work, after opening the drill i opened the back of the motor , it was press fit, had to make a small tool to open it , some light hammering was involved to bend the taps out if the way and take the back of the motor out cleaned the carbon brushes, put it back together , that didn't fix it, cleaned between the copper plates with a needle, put it back together , that didn't fix it, then cleaned the copper plates with alcohol, that also didn't work, then finally with nothing to lose tried paint thinner, and that what actually worked
Thank you for taking the time to create this tutorial. I had the same issue with my Porter Cable drill. The motor was covered in grime. I used the only cleaner I had Oxyclean spray, works fine now as far as I can tell. 👍🍻🇨🇦
I was skeptical at first but then I figure what do i have to lose... and I tried it. IT WORKS! I did exactly the same thing, soak the motor in thinner and let it swim around for a few minutes then let it dry for a couple of hours. After putting everything back, and switching it on, it was still smoking but i keep pressing the trigger and smoke is gone. There is still some sparks inside but it's way better than the smoke. Should last a while I think. Anyway, just wanted to say THANKS!
Yes, that's right. But it will only clean off all the black soot and dirt caused by the spark. It worked for a few days then it was totally blown. I opened it up and it seems that one of the brushes was broken. Unfortunately for my model, I cannot replace the brushes. I ended up buying a new china brand drill which cost the same as the price of a new motor (bosch) and I'm happy with it!
It worked! Haha saved me 100 bucks. I did take the motor apart on the brush side and clean the communtator bars and gaps between each. Reoiled the bushing and It works like it should
Çok teşekkür ederim, Makita hayata döndü, ben sentetik tiner inceltici kullandım. Tamirciye götürmüştüm , motor değişmeli demişti. ama senin videoyu seyrettim ve artık Makita sorunsuz ve dumansız çalışıyor.
If any of you don' t want to dissemble the unit, just spray the opening with brake cleaner, just make sure the front of the drill is facing up when spraying so that the liquid will drain out at the bottom, it has fixed my smoking B&D drill. i hope it helps.
One thing this video didn't mention that is extremely important is do not use a thinner that has ANY amount of acetone in it near the brushes in the motor. Acetone will severely weaken the carbon brushes and then it's just a matter of a very short time before one breaks
Wish there was an easier way to find this when i thought my drill was just dying. Had my suspicions a year ago, cleaned a bit with a paper towel recently and it's started working again.
Can't believe it. It actually worked! My drill was smoking like mad, and this method fixed it! Time will tell how long this will last, but thanks to this fix I'll be able to use my drill for just a little while longer. :)
Nice video, I'd have used a syringe to force some liquid in to help clean. I have that exact same drill, 2 of them actually, one I'm converting to Li-ion, haven't had to clean the motor yet but it's good to know how, if it ever comes up.
The only problem is those were ball bearings the reason why they were moving around because you probably washed the grease out those ball bearings have to have Grease and you can't just put WD-40 on there that won't work ball bearings get hot they have to have Grease when putting those ball bearings back in the place you might want added a little bit of a electrical grease in there
Back in my Grandad's day B&D make fantastic metal cased drills that worked forever. Now their stuff is crap. They do still make good product under their DeWalt brand but anything B&D brand is now just budget rubbish.
It worked, no more smoking, but now my drill doesn't spin. The bit extending from the motor spins, that locks into the tri-gear set, which should move the next tri-gear set on the other side of the barrier, those are locked into the pins, but somehow this doesn't translate into a spinning drill (Is it bizarre that mine had only 4 ball bearings inside with 4 small cylinders filling 4/8 holes? Model CD180s). Should the first tri-gear set rotate when operating, or should they spin in place and force the larger ring to rotate? Any thoughts?
well I tried my best but maybe after 9 years of use it’s about time to replace it with a new one. The motor was just way too slow and perhaps the battery 🔋 is not charging properly anymore. However, after doing this it didn’t smoke anymore.
@@RealAmerica1776 it lasted probably about 8 minutes of on and off use it was sparking and smokeing then it was short flames still worked then it just caught on fire and didn’t work but I swapped the motor out with from 9 volt matrix and the wires to my 20 volt and fit perfectly works haha

Thanks a lot for typing such a long and informative comment......... It really helped me out 😃😃

These types of drills are usually low quality, I'm not surprised the motor started smoking
With that amount of ability, you must run the railways!.

Rippa Sama is it the same thinner that is used to thin the paint?
Yes, that's right. But it will only clean off all the black soot and dirt caused by the spark. It worked for a few days then it was totally blown.

Gracias por el video... pude recuperar mi taladro. Saludos desde Colombia
Bro, this worked fine for me.. I used Iso Propyl Alcohol (Lamposov used in spirit lamp) instead of thinner.. Thanks a lot..

seems sketchy at first, but i just tried with this method and it works!
Worked for me thanks. was about to through out. I used White spirits. Had to run the drill for a few minutes to clear it but not works. thanks
You should have voiceovered this video, great work bro!!!!
Can't believe it. It actually worked! My drill was smoking like mad, and this method fixed it! Time will tell how long this will last, but thanks to this fix I'll be able to use my drill for just a little while longer. :)
Thanks man! This saved me money!
Me podría regalar una foto de la coneccion de los cables del swich de este mismo taladro???

Thank u....thank u....thank u
can we use contact cleaner ?
This does in fact happen due to worn carbon brushes, carbon does wear out with high range friction.
What paint thinner you did use exactly? Diesel based or cellulosique ?
Thanks bro
nice job!
legal! bom tutorial!! as vezes a escova de carvão tem que trocar, a vida útil já deu.
The wirers on the motor are not soldered they have stake on connectors,just pull them off.
Very good tutorial.
I bet that done the carbon brushes the world of good 👍 I add flammable liquids to all black and decker power tools
You realise it evaporated long ago right?? If its wet enough to catch flame it's too wet to work
I learned after a few years that Black & Decker makes Crap!
many any years ago there stuff was great but now its bottom of the pile plastic geared throw away garbage
Back in my Grandad's day B&D make fantastic metal cased drills that worked forever. Now their stuff is crap. They do still make good product under their DeWalt brand but anything B&D brand is now just budget rubbish.
Wow plastic gearbox.
Its realy black and decker?
Is that RS775 motor in the drill?
I wonder if a really powerful air gun could have just sprayed it out? Like they do when cleaning electronics( computers, tvs,etc.)

Assalamualaikum nk ty. Drill sy ad karen kat body depan. Knp eh
I discover soke from the trigger switch of my 12V drill. Do i wash the small circuit board in thinnee too?
well I tried my best but maybe after 9 years of use it’s about time to replace it with a new one. The motor was just way too slow and perhaps the battery 🔋 is not charging properly anymore. However, after doing this it didn’t smoke anymore.
what is this liquid cleaner?
Thinner
Lacquer on copper wirring is overheated, new motor is about 7euro on Aliexpres or ebay 😉
are two spheres in each hole?
Yep, they dont let the Torque Clutch move accidently, they make it bounce on each torque selection
Thanks sir
deos this works on other brand?
Nice
what is the name of the dc motor ?? what model ?? Please helpme
Is that ordinary thinner
That's right. It's ordinary thinner.
Use 99% isopropyl alcohol. Don't use thinner!
Bro I want you ask a question does it is okk to have little bit spark on new cordless drill
No
Why would you use a screw driver if you got a drill in hand ?? smh
very sceptical but willing to try, otherwise throw it in the trash and buy another brand
Aya na kasi umaandar
what is the cleaner?
Thinner
I just keep using mine until it caught on fire haha on the matrix
Hey Brian, how long did that take? Lol, my Matrix motor just started sparking a little bit ago and now it sparks every time I hit the button
@@RealAmerica1776 it lasted probably about 8 minutes of on and off use it was sparking and smokeing then it was short flames still worked then it just caught on fire and didn’t work but I swapped the motor out with from 9 volt matrix and the wires to my 20 volt and fit perfectly works haha
@@RealAmerica1776 it’s best to put on some kind of gloves to be safe because my shot out flames but the moter is pretty much gone I believe
Can of CRC spray electric contact cleaner would probably do the job without disassembly.
Big Pickel did it work with contact cleaner ?
Did it work?
You just removed the lubrication from the bearings - not a good idea if you want the motor to last.
The motor was junk anyway, with this method atleast you can use it for a bit longer.
