If you cannot afford or cannot find a suitable gear puller, you need to place a strong slotted bar between the gear and the motor. Support that bar so the motor is hanging free, then tap the shaft through the gear.

Yes, a pinion gear puller is the ideal solution. Here is the one I use on my smaller motors czcams.com/video/IHynDl_EBHA/video.html
Isnt it great when you need advice on fixing something, when someone else has already come across a similar issue and then has the patience to upload it for everyone. The essence of youtube i guess.Thank You for ur time and effort. Top stuff😊
There are tools for doing this without destroying the motor. In this case, I was not worried about it 👍 Thanks for the kind words 😊
Thanks buddy. Tryin to turn my electric skateboard into a gas powered skateboard and I needed that part. I got it now!
I made a mess of this but the principle was right 😁
I took my cordless drill apart when it stopped working and found the motor was faulty. It might be possible to source a replacement motor but it probably would not come with a matching gear on the shaft so I thought it would be best to remove the existing one from the old motor shaft.
I got the same problem, damn pinion won't budge
@@ARCANEmateCLAN heating the pinion gear "usually" helps, but if you take too long the shaft will also heat up and that does not help.
This was really useful to watch
Haha, thanks. It is probably a good demonstration of how to make a real mess of things and what you should avoid doing if you want to do this yourself. Ideally you would use a gear puller but if you are only doing the one then buying a puller is an extra expense. Note the old motor was destroyed in the process so not a good demonstration but I published it as a "public information film" 😆😁👍
GrandadIsAnOldMan 👍
I've used several of your videos to help on my projects, and all have seemed to be very useful. Are you still tinkering with small gadgets and small remote control vehicles? You did a military tank build once that was a conversion from non-RC to fully functional RC conversion. After seeing your vid, I built 4 different tracked vehicles that worked out great. The problem I'm facing now is that I destroy nylon gears nonstop. So I've been switching to more durable brass gears, so your vid was really helpful for removal/installation and I didn't have to go buy a pinion gear puller. Long story longer, Thank you for sharing your projects!
I still think a pinion puller is a good investment. I did buy one for use on smaller motors than this one and it does make life a lot easier 😊👍
Great video man! This really helped me :)
Thanks. The main point here is I was only trying to recover the gear, the motor itself was effectively destroyed. If you just wanted to change the gear on a good motor you would need to support the gear so no pressure was put on the motor bearings.
I've got some bigger (yet still pretty small) DC motors at work..... actually an entire 3 boxes full.. lately when I've built stuff it's been with old hubsan x4 flight controllers or similar. I'm wondering if you have or could possibly find the time to make a video about potentiometers and speed control w/ out a flight controller using potentiometers? Thanks for helping out! Cheers!
I am no electronics expert but this video might give you some ideas czcams.com/video/Y9vFdjiOiIo/video.html
All these motors are made by industry standard manufacturer Johnson Electric or if a clone it is based upon a model of Johnson Electric.
Is there any other way man? I'm dying to losen up the gear from dc motor that i got from an old printer
The proper way to do it would be to buy a sprocket puller or pinion gear puller (just different names for the same thing as far as I know). They push the shaft through the gear whilst correctly holding the gear in place. If you study pictures of a gear puller you could probably make one yourself. The main thing is to support the gear while you punch the shaft free. In this video I am relying on the bearing of the motor to take the strain and basically destroyed the motor doing it. I knew that would happen but I only wanted to salvage the gear not the motor. This video may give you the general idea but it depends what you can find to do the job czcams.com/video/zgDD51pBAzs/video.html and heating the gear should help by expanding it enough to reduce the grip on the shaft.
GrandadIsAnOldMan alright, thanks sir
Did you manage to do it in the end? Im trying to remove the gear from a printer motor too
@@rupertshearer1456 i finally am using angle grinder as well 😑
Good news! Those are only $3.95 at my work!😀
:-)
Very useful vdo solved my
issue Thank you
This was not the best way to do it but I was only interested in saving that gear, not the motor.
Very good how to video.
+magnetman2010 thanks, took a lot longer to do than expected as I was being too gentle with the torch initially.
Knowing when to give up!
Or to buy the correct tools 🤣 Gear pullers are available, but obviously that is another expense.
Have the same problem with my Parkside dril. I bought for £!0 a brand new motor from China here UK in a week. Now I have to change the gears ! I wonder if a cig lighter would easilly heat the gear - brass has a higher coefficient of expansion than the steel shaft. However I see on CZcams vides on how to make small pullers.
If you can get something behind the gear to support it then drifting it through would be a much better solution than smashing the motor like I did here. I have had success with smaller motors by cutting a slot the size of the shaft in a strip of steel and supporting that while I tap the shaft through. Using a cig lighter might work but I would expect the heat would be so gentle it would transfer through to the steel shaft before the brass gear had expanded enough to release. The obvious answer it try it, what have you got to lose. If it doesn't work you will have to go hotter faster.
Terima kasih
What are you doing?
you forget the copper wire !!!
Friendly greetings from The Netherlands!

Even if you can get another motor, how do you reckon you out the gear in the new motor ... I doubt loctite is not up to a challenge in heavy stress application like drills or 20v power tools.
Not sure if you missed some words in your comment, I don't understand "how do you reckon you out the gear" and as for loctite, did I mention that? I would have to watch my 6 year old video again to find out. The gear is an interference fit, hence the need heat it to expand it, so it can be removed. You could use a proper gear puller as suggested in the video description. Fitting it on the shaft of a new motor would require force, ideally in a vise or press to ensure alignment.
U r a pro bro
This is definitely not the best way to do this, but I had a go.
Aliexpress I believe it's a rs550 motor about 10$ usd. They also sell the brushes.
Thanks
Hello what to do with gear not fix on the axeof the dc motor is splitting up and down
If the gear is split you will have to replace it
Did you manage to find a motor?
@@RickJeanes I bought a better cordless drill instead. But you could probably find a replacement motor on eBay or similar.
I found a motor at 1/3 the price but time will tell if it's any good I guess...oh, thanks for the video too.
@@RickJeanes Good luck 👍👍 One reason for not trying too hard to fix it was the battery wasn't lasting very long either, so that would have been the next thing to pay for 👍👍
after you heated it you barely hit it and it popped right out... i have the same drill motor issue... i found a new motor for 16.50 vs dewalts $50 one with gear al ready on... i will also have to cut approx 1/4 inch off new motor shaft...
Good luck with that 👍
@@GrandadIsAnOldMan i did it without heat i just held it with side cutter plyiers and 2 blocks of wood... i let motor hang and used a nice center punch with a small hammer and it came right off... i did not have to cut new motor shaft since it had plenty of clearance... i paid $17 for new dewalt motor without gears and wire... drill works perfect....
@@roadstar499 that is a great result 🙂👍👍
didn't heat it nearly enough. Oxy-acetylene is required to fully aneal the gear to butter-like softness.
That's fine if you have the equipment available.
Your block of wood looks every bit like a house brick !
If the copper wire is still crimped or soldered to the bent commutator segment, you can often bend it back without issue. Happens on small toy motors too. The first few thousand revs reseat it properly, or rebreak it.
Can you make a blowtorch powered car ? .....am joking :)
+slider2732 I have a nice new 18v Li-ion powered cordless drill now, was lucky at the local hardware store had a special deal on some Black & Decker's £50 seems very nice so we will see how long it lasts.
'hardware store' ? i'm not that American yet dear sir lol, B&Q are though a bit of a distant memory. The end gear was still a good idea to remove from the other - am quite sure that a drill with a busted chuck or stripped gears might turn up in bargain hunting, to take the motor from.
slider2732 as it happens, yes it was B&Q :-)
Thanks
I made hard work of this, there is probably an easier way 👍
@@GrandadIsAnOldMan I have visualised few videos, you are the best
How how do you put that gear on a new shaft?
As I said in my previous reply - The gear is an interference fit, hence the need heat it to expand it, so it can be removed. You could use a proper gear puller as suggested in the video description. Fitting it on the shaft of a new motor would require force, ideally in a vise or a press to ensure alignment.
Mate I’ve took mine off but how do I put it back onto my new motor? A g clamp maybe.
Putting it on 'should' be much easier. Warming it might be an idea but I would expect it go on cold by placing it on a flat surface and gently tapping the other end of the shaft. If your G-Clamp is sturdy enough that would work too and allow you to be gentle with it. I know the clamps I have would probably twist out of alignment. A nice big vise or vice (if you are in the UK) would also do the job nicely.
Heat It . Drake 1 ton press , Hobby Vise , "C" Clamp in USA .
Beat the crap out of the shaft, but jo joy 'till I torched the gear. Voila :)
Certainly not the most efficient way of doing the job, obviously proper tools are available 😆 details in the description 👍
You probably could have just bought a new brush to replace the burnt out one for a few pounds, it only takes a pair of pliers and a quick solder to replace.
True 😁👍 If you look you will see it is the commutator leaves that have failed, not the brushes. It might have been possible to get the leaves to settle down again with a bit of effort, maybe, but I decided to take it apart. 04:55
How do i remove it without destroying the motor :) i ve have 2 same motor for cordless drill but different gear teeth....i can destroy one of the motors but on the other one i can't afford because it has to receive the first motor gear
The ideal solution is that you buy a proper gear puller, see the details in the video description. Without that, you need to place a strong slotted bar between the gear and the motor. Support that bar so the motor is hanging free, then tap the shaft through the gear. I do it here with a much smaller motor, but the principle is the same czcams.com/video/zgDD51pBAzs/video.html
How can get This type of gear
You would have to search online stores. You would also need to take careful measurements so you order the right items. You need length, diameter, number of teeth, inside diameter for the hole for the shaft.
How you connect the used gear to new motor ? do i need to use glue ? heat ?
This particular gear was an interference fit so heating the gear would help it to fit the shaft
so if i remove the gear (small grey) can I connect it again to the my new motor , do i need Glue or just heat (blower) ?
Dudeman. Could ya compress down the blow torch volume? I'm wearing bone conduction headphones, I thought I was legit gonna die
Thank you for watching, you may find the information in the video description useful.
You have not disassembled the motor.... You have destroyed it....
Yes, well spotted 🤣😆😁
@@GrandadIsAnOldMan 😉😁
Would this ruin my motor
Heating the gear to remove it is a common method but you need to be careful. You only want to heat the gear so it expands reducing it's grip on the shaft. If you allow the shaft to become hot then that expands too and that makes the grip tighter not looser. If you take too long the heat will travel up the shaft and may cause problems inside the motor.
You may have missed the point that this motor was already ruined so I am just taking the gear off so I can use it on another motor so I am not too worried about this motor. You really need to support the gear by sliding a strip of metal with a slot the width of the shaft between it and the motor. Then you support that strip of metal in a vice so no force is applied to the motor casing and bearing. Here is a video working on a much smaller motor but the principle is the same czcams.com/video/zgDD51pBAzs/video.html
the motor you need is a johnson 600 and there £12 for 3
+Matt Westmacott thanks for the suggestion but what makes you so confident? If it is not exactly the same size and same shaft diameter and length then it would just be a waste of money, although 3 nice solid motors like that for £12 could be handy for all sorts of my projects. I did google the details on the motor and found matching items but decided I would rather put the money towards a new 18 volt Li-Ion cordless £50 special deal at B&Q. The NiCad batteries on that old one didn't hold charge for very long anyway so it really didn't seem worth the effort of fixing it.
I got three for `12 quid from ebay just to mess around with, their the same as you have there.
as for removing the little gear id hold the gear with a vice and tap the motor spindle with a prodder whilst supporting the underside of the gear so not to squash the gear as then it would make all this impossible!
loving your channel
You burned coils coating
I was only interested in getting the gear off. The motor was faulty.

+Francisco Javier Lázaro Pinela thanks, I did google the details on the motor and found matching items but decided I would rather put the money towards a new 18 volt Li-Ion cordless £50 special deal at B&Q.

I need that thing off
I made very hard work of this and ruined the motor, luckily it was already dead 😆
There are very chip pullers I think that prosedure is to primitive
Yes a very primitive and destructive approach not recommended but makes good CZcams fun 😀
Just a thought, did you spot the pinned comment?
Pls use pinion Gear puller.
If I had one I would but then that wouldn't be a very interesting video, pulling it off without destroying the motor. As Slider2732 pointed out in the comments here, I could probably have reseated the commutator brushes and saved it but I didn't think of that either.
This is a great video but I'm trying to concentrate on what you're doing and I see something jiggling in my upper right hand corner I look that's a damn Snowman that's funny great vid
I must dig him out again sometime. He is currently buried under the junk on my work desk which I haven't used in years 🙂
Triknya kalah sama orang indonesia

Man those motors cost only a few buck when you just order from china 40 bucks is a ripoff
I think I was talking about a direct replacement for an original manufacturer's item. As you say, cheaper would be available. As this video is about 7 years old, it is hardly relevant anyway. The video was just to show a very ineffective way of removing the gear. A proper gear puller would do the job quicker and easier.
@@GrandadIsAnOldMan well it works so it is effective!
@@Andre_Thomasson Haha, yes, but not much chance of repairing the old motor now 😆😆👍👍
I'm in deep shit now... I still need my moter...
Your best bet is to find another faulty one and swap the parts.
I found a use For my motor with the gear but here's a tip you can get motors of Aliexspress and Amazon you can get one 12v motor for around 5 - 13$ and a 24v for about 17 - 30$
And most 12v or 24v motors have the same size shaft you just need to know what volt your motor is
