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
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.
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.
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
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
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!
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.
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.
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.
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
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. 👍🍻🇨🇦
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.
@@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
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. :)
