Free DeWALT DW920 Teardown And Repair

Detailed teardown, repair, and assembly of a non-working cordless driver given to me by a friend.

[@crazyskull88]

Worth it. These things aren't made anymore. I have x2 now. Both repairs and the one working I been using it every day for the past 2 yrs

[@Ricovette]

Thoroughly enjoyed this upload! I've had my DW920 for over 16 years now and it works today just like it did the very first day! Best cordless screwdriver I've ever owned... Thumbs up from me on this upload... Stay safe... Rico

[@rome288]

Agree that dw920 is the best. I had to stick a crowbar into my wallet and pull out $100 20 years ago... it has been the best electric tool ever... right size, right amount of power.

[@tomlocke5130]

Thanks to your video, the only online regarding my DE920, I was able to make the same repairs repair as you featured.

[@davidhitchner9448]

This video saved me. Same issue with a broken wire. When pulling apart the case to replace the wires the gearbox came apart and I had no clue how to put it back together. I had bearings and parts everywhere. Luckily I found all the parts and was able to reassemble everything. I also found 2 internal screws very loose and tightened them. Thanks so much for this video.

[@hkliu6975]

Mine has been broken for a few year, I won't take it apart ,i can't beat it anymore .I say your video today. thank you very much for sharing.

This model is a great electric screwdriver. It does have tremendous as well for a little thing. I’ve had mine for over 10 years. I use it five days a week. I had a little bit of smoke come out of the motor few times when under heavy load, but it’s still kicking.

[@rome288]

Thanks for the video. It enabled me to repair my dewalt screwdriver. It needed new wires soldered on. Before your video, i was stuck trying to figure out how to access the motor. I also liked your technique of putting the solder on your vice while tinning the wires.

[@amrosla67]

Thanks for all your time and effort with this video, ... I found this same drill off the refuse route and was scratching my head as what direction I was going to take. I got the drill and charger, ... but my co-worker had cycled the batteries in the packer before I could stop him. I think I will try picking up a new battery and try this before disassembly. Take care and thanks again!!! Art

[@bennyrlove]

got a metal skill saw that way - bought at a yard sale taken apart in a box - loved fixing it

[@mail06513]

Thank you! Excellent video. My drill stopped working a few days ago and I'm going to try and fix it now after having watched your video. By the way this is my favorite electric screwdriver because its the only inline electric screwdriver with variable speed .

[@jamessiberrysaunders402]

Great video, good to see people fix things and not just throw it out!

[@mikelilley]

Brother, you are one clever individual. Enjoyed this video very much! I just purchased this device at home depot and came across your video while looking at reviews. The engineering design on the clutch was indeed fascinating. Cheers man!

[@ZackOfAllTrades]

Hey netnole thanks a lot for that compliment, I don't know how clever I am but I've taken apart so many thousand things in my time that I eventually started understanding how stuff works and can occasionally get stuff to work again :) I'm really glad you enjoyed it, check back because I have another 2 "can it be saved" episodes on the plate that I hope to do before too long. Thank you for spending your time watching my video. ~Z

[@xxycom8963]

Very nice video 👍. Thanks. Inspired me not to open the innards of a Dewalt 920. I will stick to the electrical part, rejuvenating the battery pack. 😁

[@totaljunk7508]

Thank you for taking the time to post this. I'm about to upgrade mine to lithium batteries. I'm sure it will be invaluable

[@Ogg_Vorbis]

Hey, thanks for the video. Hope to see more like it from you. I've always enjoyed teardown and repair videos.

[@ZackOfAllTrades]

Thanks Mykel, I love tearing broken stuff apart with the intent to fix. After all, what's to lose? it's already broke.

[@tunyung]

Going to do my after seeing your video! Thanks!

[@andrewevans545]

I just bought a used one for $20. Charged one battery and meaaured the voltage. +8v. Popped the battery in and nothing. I then ohmed the inside battery connections +&-, pressed trigger and got .003 ohms forward and rev. My guess is either the motor is toast or the 2 wires are touching where it pivots. Thanks for the teardown. I'm not planning on opening up the planetary gears. May spray some lithium grease inside somehow or some light oil if I can get the motor to work. Again, thanks

[@sarahmartin127]

Brilliant video, I'm a soft Furnisher so I take apart and fix my sewing machines and even my Henry hoover....and they worked again. It is such a thrill to do. My dewalt screw driver has given up on me and I'm not sure if both batteries are dead or it's the pinched wires🤪 . I'm hoping it's the batteries lol thanks again

[@maziarkarimi2195]

Very good ❤❤

[@Dan988R]

Cheers just had one of these in pieces. This video saved me alot of time.

[@colinblankenship2401]

thanks for sharing

[@moldingpro7208]

A great example of patience!

[@ZackOfAllTrades]

I'm not too sure Louis, whether it was patience or pride "I'm not gonna let this thing get the best of me" :) at any rate, I sure appreciate you watching.

[@nicksassany486]

Love my DW920 ,best screw driver, very informative incase this happens to me. Alittle extra grease in the clutch and gear case wouldn't hurt.

[@ZackOfAllTrades]

It really is a solid tool, and one I'll use a lot. I think knowing where it wears is helpful because if you keep the bending to a minimum you may never have to fix it.

[@pieterjoubert4346]

Absolutely brilliant! Will save me plenty of time. thanks!

[@SerendipitousBagHat]

Thanks for doing the dirty work. I have one of those, good to know how to fix them.

[@bothann]

Great stuff, Zack, very inspiring. Also, 'unbugger' is now officially part of my vocabulary. ;)

[@ZackOfAllTrades]

Thanks Johann I wish I could remember where I heard it, I've always found it funny.

[@galileomeloni4967]

Grazie ! non sapevo come cambiare un filo rotto - con questo video oh visto come aprire l'avvitatore DEWALT DW 920 -

[@galileomeloni4967]

Aperto !! tante sfere ci sono !! piano piano gli troverò il posto giusto Grazie mille per il video

[@ATeaNTea]

Thanks you

[@granjaguar8964]

I have the same exact tool, thanks to you I know how to take it a part, check it out and repair it. Thank you./Gracias.

[@davidjeffery9531]

Thanks you just saved my "old faithful" from the recycling bin. Working a treat now. However I have the driver bit stuck and suggestion welcome ?

[@TheMacGeek]

Thanks for the video! I also have the same tool, and my trigger switch is going bad. Now I know how to take it apart. I also like fixing things for fun.

[@ephoto09]

Great video and yes I’m inspired. Thank you

[@rico5527]

Thanks for this! Mine has slowed down quite so much it won't tighten anything. Hopefully it's just the wires!

[@myyube81]

You definitely inspired me.🤓

[@davidphipps46]

Just found one of those at a thrift store for $2.00.I have been able to find the user manual and instruction manuals but not a pdf file with the exploded parts diagram. Great video , I also find and repair old tools (power and hand). When I find them online I ask - does it work and has to have as little plastic as possible.

[@adriangutierrez9170]

What type of grease should I use and what areas to put it in, thank you for such a good informative video I appreciate your time that you put into it, I have the same one, it is working right now,but my two batteries that came with it in the case are over, and I don't know how to go about it or should just buy those cheap ones at eBay, what do you think? Thank you

[@georgenesoliveira9100]

Otimo !!!

[@hilldwler420]

What happened to the 3 extra bbs in the plastic container? Where did they go?

[@hardlyb]

Have you used the tool in the interim? If so, what do you think of it.

[@paulm9639]

liked it. new sub!

[@rico5527]

Have an issue with mine, the switch direction button isn't attached to anything on the motor. Looks like the motor attached to a the loop on the switch somehow but not the switch floats freely. Maybe I'm missing somthing

[@olegvoevodin3201]

Why didn't you add grease to the gearbox?

[@brendasmith1930]

love my screwdiver but cant figure out how to tighten chuck

[@olegvoevodin3201]

Hi, how do I remove the studs to remove the gearbox?

[@jasoncook5307]

i really liked that ziplock back you used to hold the parts from the drill, it had peg board holes above the zipper, who makes them and what are they called/ and where are they from.

[@ZackOfAllTrades]

Hey Jason, those are what we call in the Navy "MAF bags". I have a collection of them that I've rescued from trash bins over the years. I found a link where you can buy 'em but they ain't cheap store.armyproperty.com/products/return-materials-document-envelope-pack-of-100-nsn-8105-00-334-4120.html

[@Grassy20]

"I hope to inspire you a little bit to possibly think about trying to fix something rather than throwing it out..." Kinda like the trailer you destroyed? :)

[@ZackOfAllTrades]

Touche mon ami. Funny timing since I'm once again making progress on that.

[@douglasmurray1829]

Thank I have two of those, I picked up broken, that I found had broken wires at the switch solder joint that I can repair now. What gauge wire did you use?

[@tteuvky]

remember me transmission gear set

[@andrzejpolski9781]

great video THANKS but you forgot to put grease in the gearbox !!! grease balls and shaft !!!

[@ZackOfAllTrades]

true, I should have

[@willemkossen]

Nice! I try to repair everything. Heck, i repaired free McDonalds Happy Meal Toys. The other side of this is the boxes with broken stuff i cant throw out because i want to repair the stuff, and it's driving my wife bonkers... Oh well...

[@ZackOfAllTrades]

Willem, the struggle is real! The collection of stuff I have "because as soon as I get rid of it I'll need it" is sometimes even troubling to me, but I forget all about that when one silly thing I have saves the day.

[@dannymatgen1796]

Can the brushes be replaced on this motor and if so are they the same brushes that would be used on any other Dewalt drill motor?

[@ZackOfAllTrades]

I don't think so on this one. I think you gotta replace the whole motor.

[@joegrochowski669]

on these switches , is the red wire positive and black negative, thanks j

[@ZackOfAllTrades]

That's correct, and why black is used as negative in DC systems and as hot in AC systems, I'll never know.

[@joegrochowski669]

thanks for reply, just subscribed

[@scotthales8737]

Got a bit stuck in the end of the drill how do I get it out

[@ZackOfAllTrades]

Hey Scott, sorry for the slow reply. If you're referring to this drill specifically, I'd say a neo-magnet glued on to the end of something. push the collar of the drill down and then pull the broken part out with the magnet. worth a shot
