Dewalt Cordless 54v 60v Saw, fair warning ⚠️.

- Spent over an hour repairing this one, and all for nothing.
Couldn't fully test it to start with because the bearing was that bad.
If it had of turned from the start I would have known the motor was already gone. But to be honest, I probably would have still changed the bearing just to make sure.
Take this as a warning ⚠️.
if you have these dewalt 54v or 60v saws, keep in eye on those bearings. if they fail like this, they can take out the motor.

Hi, I repaired one and had the same issue and I keep rotating the tackle until I found the correct orientation, it has to be on the same spot as when it comes off, when I saw you taking it off I thought you knew something that I didn't, is clocked too the armature and the speed controller knows where the location of the armature magnets are, hope this helps you.
Probably the best idea is before taking the back bearing mark the tackle and the armature with a marker to know the correct location, like timing an engine
But it was already doing it before he took it apart?
There is a white marking on the tackle. Is this from the factory? And anyway - if this is so important, then why donˋt DeWalt tell you in the breakdown or other technical information? Same reason, why they put cheap bearings in their tools: they want to sell new machines.
@@AlexKall Was it though? he said he couldn't test it bacause of the faulty bearing/
Battery powered?

Glad you got your channel back mate!
Me too!
Great content always interesting to watch looking forward to the next drop
Great video thank you.👍
Habe auch das Problem gefunden. Es sind 2 Punkte auf dem Hallgeber und eine Markierung auf dem Anker. 1 Markierung auf dem Hallgeber muss mit der Markierung am Anker übereinstimmen, dann läuft es wieder!!!
Someone else posted a similar comment. After the holidays I must dismantle this machine and try this.
Always interesting Dean fix or no fix thanks for sharing 🦘
Thanks for watching!
Had a Milwaukee impact do the same thing, wouldn’t run correctly was the Hall effect sensor but it’s only had 1 of 3 positions for the armature to be in and of course didn’t put it in the correct position. It’s possible that the tacho has a small variation in magnet position on the disc and has be calibrated out via computer to make them run.
Great way of reducing repairability without the equipment.
The biggest problem I have always had with battery operated tools it the battery going bad long before the tool goes bad, and the replacement battery is over 1/2 the cost of the machine. That is why I prefer to stick with corded tools as much as possible.
I know thefeeling all too well. These days with all the brushless machines and motor/controler issues, whenever I work on one of them I learned myself to test the motors before fully reassemling the machines again.
Ive not had good luck with DeWalt power tools. Usually poor quality sintered parts have been my problem.
That blade has nearly a quarter of its life left! 😆
Hi Dean, nice video. Can relate when trying to fix and a new problem arises that were hidden by the first problem.
One question though, why can’t you just change the field? Or are they to expensive? Only sold with controller?
I have not so much experience with DeWalt, mainly work with Makita.
Makita sure do know how to have a good logo for signs sweet.
Engagement how's it going?
What you think about other bearings like FŁT, skf, or nmb?
Hi. Ive had lots of these type of default machines in the workshop for repair and advise them that if they want to continue with the brand then get the three year warranty because as sure as the sun rises they'll be claiming against it..Maistone Kent
I always preach to take out the 3 years warranty for all brands, but noone ever listens.
Glad channel back when you quote the bearing numbers are these a universal code number to any brand of bearing or just to each manufacturer ? Thanks always find you informative .
Yes, the numbers are generally used by all the manufacturers. You can also measure ID, Width & OD in millimeters with a caliper and find them in a catalog or online that way. There's suffixes on the numbers sometimes too indicating the covers on the sides, protecting the insides - rubber, steel, plastic, etc. 👍🏻👌🏻🛠️🔧🔩

I know its onlt cheap bearings but if someone does a fix on a machine and its still not working would the new parts be taken out again to be used again or is it a loss
The new parts stay on the tool and go back to the customer because they paid for them.
Never liked DeWalt tools, always been a Makita and Hitachi man myself but everyone to there own😀
Where do you buy the extra long driver bits Dean? Been doing some DIY where they would come in useful. Always in woodies and b&q never come across them.
Ah, don't worry, there will always be something to make a pokey out of.
I believe they are a set of Wiha bits, a 'system VI' set iirc.
how do i get in contact with u dean, need a titan sds with no power and a marchrist core drill looked at
The exact same thing happened to me Dean remember I was asking you about it
I do, did you ever get it running again. Someone else commented that the tachometer needs to be in a certain position on the rotor. So I might give this one a second go and see if that works.
I thought that those were worm drive saw just like the older models, DeWalt just kept the shape.
So!... Should I avoid buying one or not? I was thinking about getting one.
Same question.
We own one and use it all the time. It’s a fantastic saw, a little heavy but it also makes heavy work seem easy so it’s worth it.
One of my favorite places to use it is if you need to rip a board lengthwise, it will power through it no problem
There wasnt a problem with it as per factory build, but basically as the owner you start to hear machine not working properly, you should think of servicing it, before it will cost loads more. Bearing started to go bad and instead of repair, they kept going where bearing blew the covers of itself and moved the armature towards the sensors.
Owned one for 3 years, was the most powerful saw I had ever used, corded or otherwise. It never skipped a beat during my ownership either. I'd recommend if you're in the market for this type of saw.
I would deffinantly recommend these saws. For the power and size of cut, there isn't many others like it.
Performance is very good, only problem is the size, weight and cost.
But that's ti be expected when you buy a saw with a bigger blade and motor.
The batteries would be more unreliable than the actual saw.
But like I point out in the video, watch the bearings. They only use cheap bearings that don't last long, so keep an ear out for them
Excellent editing skills when you gaffer taped over Kevin's phone number
Where do you source your parts from? I’ve got a couple tools down I’d like to repair!
Online....
Vague answer for a vague question! 😅
@@tdotw77 😂😂😂🙄
@@tdotw77 there are several suppliers. I’ve looked. Was wondering where he sourced his parts from because it’s likely a reputable and trustworthy spot. Wasn’t too vague at all.
Gfy
The quality of some dewalt tools can be shockingly poor.
I have a 887 impact driver that has started to fail and the accompanying drill driver that is stuck in hammer action, both tools have done little work.
It seems that not only have you to be the tradesman with the need for the tool but a mechanic is keep them running.
Dean, Mick from Buy it Fix it, on YT has done Hall Effect replacements on Milwalke tools and they can be done. Excellent video as always..
I believe he also changed mosfets successfully. They can be done but its still pathetic how Milwaukee and blown electronics go hand in hand.
Im thinking if Dewalt can you offer thecnical support by eamil or phone to ask if the problem is in the positions of the motor against the sensors? I dont know
They wouldn't know or wouldn't tell you
To me this is unacceptable from DeWalt. If they decide to save pennys on cheap bearings that will ruin my tool thats not a "professional" tool brand worth paying for.
Hii man . I am a metal fabricator from india ! I use dewalt corded 4 inch grinder 11 thousand rpm and after using it for tile cutting... it picksup speed slowly and also feels like bearing has lost lubrication. Please suggest
Probably the bearing has picked up dust and is slowly grinding itself to death. I suggest pulling the rotor and check it's rear bearing and the brushes. Bit more involved procedure is to take apart the gear housing or "the head" of the grinder, and see if the big bearing on the output shaft is done for. If the output shaft is hard to turn by hand when the gear housing is disconnected from motor then main bearing in the gear housing on the output shaft is blown.
How much off a difference would there be between the cheap bearings and a name Brand. I know Dewalt would be buying millions but surely it would help the brand with better quality tools
You'd think that a professional tool would use a quality bearing.
Almost none of them do anymore
@@Vanman_fr I recall Dean doing a strip down of a Chinese power tool which had NSK bearings.
@UnCoolDad that is true, it was a mellif brand if I remember correctly but that's kinda a special case since I'm pretty sure they did that just so they could advertise that they used nsk bearings. He stripped down other tools from the same brand in the same video and they all had cheaper bearings.
@@Vanman_fr I wouldn't be surprised if they were fake NSK bearings 😬
Same thing you can say about Mafell, price is very high, but its often built like a DIY brand.

Thanks for the reminder good sir.
Good call!
I forgot
Yup
👌💯💯
The problem is that its not a Makita.
You ever have to look at disassembly off camera cause you’re brain said nope on reassembling the item?🤨
Не правильно установлен магнит, изначально то все работало😮
Such a shame to have to scrap an otherwise working saw for the sake of a dead hall effect sensor(s).
Looks like "Complicated Crap" to me.
Better corded, simple, reliable, cheaper. I can't imagine how much cost that battery, maybe you can buy two corded dwalts for the price. Nice video Dean.
видимо вы никогда не работали на крыше
@@ВладимирПетров-в4мOr anyplace that you don't have access to electricity(new builds, remodels, off grid projects in the country, etc). These saws can cut lumber all day on 1 or maybe 2 batteries. I have the 20v version and it does everything my trusty old corded porter cable saw can do and then some! All these cordless li-ion tools have given us the ability to not need to use a extension cord or plug into an outlet all day with enough batteries(I'm at 15+ right now)👌🏻👍🏻🛠️🔧🔩🦺🔌🔋🚫
@@ВладимирПетров-в4м That's literally the only reason to buy a cordless circular saw.
@@zaxmaxlax я живу в России и у меня очень много аккумуляторного инструмента от макиты. Работаю только у себя дома. Если нет денег то лучше купить сетевой.
@@ВладимирПетров-в4м Roofs, doors, floors, windows, fences, kitchen furniture, all kinds of installations, I agree that a battery-powered tool can be more practical and comfortable, but not owning one is no excuse to stop working, look at the size of that saw, it is massive, for me one of the most positive points of battery-powered tools was their compact size and weight, for cost and benefit I still prefer cabled tools.
I've repaired a bunch of hall effect sensors in tools, and it has 50% chance of it working.
Many times especially in drills and angle grinders, dust and metal fillings enter motors and strip or short the hall effect sensors, and sometimes this ruins the BLDC controller input as well (no fix in that case).
Most of hall boards can be easily tested - either with multimeter or oscilloscope, they just need a magnet and +3 or 5v power to test.
You can also build a simple hall sensor testing board like this: ua-cam.com/video/6N6OR341qQc/v-deo.html
most of hall sensors are interchangeable and can be made to work regardless of what was originally there - just look at datasheet at how they need to be wired (wire capacitor, pullup or pulldown resistor properly, i've even had to put pulldown resistor into area usually reserved for capacitor) - controller only cares about binary input in the end.
That's good to know, thanks for that.
So long as any electronic control components are not potted it is possible to replace or repair them.
Seems a shame to have to scrap this saw because of a failed hall sensor.
@@stevejagger8602 it is possible to remove potting and repair controllers too. Dewalt white silicone is easily removed with nylon pick, and makita epoxy is softened with heat - use hot air and a nylon pick or you can even cook it and then easily clean with a nylon pick.
@@jernejloknar8011 thank you for that. The problem that I have found with potting compounds is being able to read component names and values after attempting to uncover their secrets
@@stevejagger8602 if you heat it up elements look great and get off chips properly, i can provide some pictures or make a video next time.
Balls that saw hasn't that much work done
don't bin it, I´d buy it ;)
Are there any tools that don't have Chineseium components?
No, there are no products full stop that do not have something produced in China. Weather its the whole product, a few parts or the materials used. Something will have come from China.
What we want to know, is did the brand specify cheap China parts or quality China parts.
Because China can produce both, and for not much difference in price.
I wish I could have one of your drills. I always wanted to have one of those battery operated drills 😊
Must be doing something right Dean is some strote wants to hack you.
I rember reading guys on the Contractor Forum several years ago saying that branded tools sold in Home Depot etc are not built to the same quality as buying direct from tool manufacturer or dealership outlets... this is to save money so they can sell them cheaper in the big box stores...
you mean same model (and revision), a different outlet -- built differently? That's a proper conspiracy.
@@stanimir4197 thats what they were sayin, strip it down and there were bushings instead of bearings ... and plastic gears... 🙄🤷♂️
@@peterfitzpatrick7032 Someone was taking the piss, or a knockoff. If they did have the same EAN - it'd be quite ridiculous, how the companies filled the paperwork.
Nah sounds like fake news to me.
Well when buying DeWalt or Milwaukee you might aswell buy the cheaper in house brands like Erbauer, Cobalt or Rigid. Rigid seems quite solid. Same made in china tool that cant really be repaired so why not just save yourself the money.
Makita. Metabo and Bosch Professional are true pro brands that are worth the extra price because they can be repaired and serviced and last longer. Just dont buy one of the new brushless corded demohammers from Metabo they have more complicated electronics and an aluminium conrod that can snap and ruin the machine. Also their woodworking tools are not as good as Makita.
Christ. Who keeps trying to take your channel and for what purpose or gain? 😑
Blades have become so expensive people don't want to replace blades quickly. In South Africa anyway. Parts for Makita are 4 to 8 months wait and this is there biggest fault. And folks that works there anyway. Also folks just don't look after the machines anymore this is why Ingco is doing so well here as they are a throw away product.
glad i dont own dewalt shit brand
You should say F-Á-G bearings instead, youtube is always listening. At 8:17 and 13:28 if you turn on the subtitles you will see the algorithm actually censors it.
Terrible isn't it?
@@AnthonyRBlackerI wouldn't say it's terrible that the subtitles censor a slur... it should be pronouned F. A. G., as it stands for "Fischer Automatische Gussstahlkugelfabrik"... he doesn't say "Skiff" or "Nisk" for the others... so not sure why he would for F. A. G. Nobody even needs to be overly sensitive about it, because when you go out of your way to be offensive... you're the problem. lol
LGBTQ+ bearings. This is where it has come to. Soon you can't even say tranny when you repair your car. 😂
