I recommend getting 7 mil or 9 mil thickness nitrile gloves. I've used those thin 5 mil ones while working on rusty cars for 20 years and they tear so easily. I got a box of 9 mil and they're AWESOME!!! They last MUCH longer for about 2-3x the price of 5 mil.
They make commutator draw blades just for that purpose. I got carried away once on a GM starter and went pretty deep. Sounded like a Mopar starter afterward....lol.Chinese-made router....commutators are cheap if available.
I dont use sand paper.. I use fine plastic finger mail file or fine metal file.since brushed are even i want the contacts to be even as well send paper will help but better to use something solid like sanding block
Great video-thanks! I have an old B&D bench grinder that suddenly stopped while I was using it...hard! It got pretty hot. Now it just buzzes. When off spins freely but turning it on magnetized it and locks it in place. Any ideas? Brushes? Thank you.
There's couple of things you can check,1 check the carbon brushes 2-your bearings or bushes might worn out,on turning it on armature magnetized to the core.
@@ZutiDIY I took it apart today. No brushes? It’s a simple motor. Just power to wrapped copper wire and a metal shaft that spins in the center. I checked everything today. All connections good. At one point it started working!! But started buzzing again. Thanks for your help
@@ZutiDIY I have this same problem with a 12 volt 4wd motor. It spins freely but when I turn it on, it locks up. There is no sign of damage inside but clearly, I’m missing something :/
So interesting...So all the elongated commutator bars should be in contact. The ones that were not making contact indicated the fault ?? I don't know if I've accurately assessed what's going on here without technical knowledge hehe
That is a hit or miss thing. I had this defect three times. This repair worked once. Be happy when it does. It's a decent machine! But I'm not a fan of applying solder to the rotor. That beast rotates FAST. If you get it out of balance, it will quickly vibrate itself to death.
@@seymourwrasse3321 If it works, it works! I know contractors that use ryobi on construction sites. Because the Hilti, Metabo and Bosch Pro get stolen all the time. ;)
Hi sir,about testing using the light bulb,how u connect the wire because at the video i saw u twisted the both of it.so i little bit confused which one positive & negative.
@ sairex5856 just letting you it’s alternating current A/C no positive & negative. But I couldn’t tell you why they were doubled and twisted. Nor did I learn how to find the short just look for the most sparks… lol
This tool made sparks. Multimeters only give values and most of the times these values are very very close to each other, making it difficult to find where exactly is the short circuit in the commutator.
@@MyJootube This is what I was looking for, I just bought a rotary tool and saw tiny sparks, was wondering if it is defective, but this video seemed to show otherwise. It is when those sparks become gigantic that I should be concerned then.
•.• the light was sort of in series, he cut one side ( either positive or negative)making it a switch which lights the bulb when the two wires are connected together •.•
I have a Bosch router and I experience that the RPM changes and not steady , slow , very slow normal , anyone have any idea on that highly appreciated.
@@kingg283 not yet , but I will , because I need that tool , I bought one Chinese one less than 10 dollars , it was working well till it starts to kick back and the plastic cover was broken so I just use it as a spare parts .
I think the problem was the type of spark, not sparking in general. At first, the sparking was coming from a specific place and there was also sound of electric shorting, meaning that is a short. At the end, the sparking was coming from rotation, which can be normal with brushed tools. I could be wrong thought.
In india whenever electronics device get problem u go to technician. he will see u with device and laugh now i cut the goat 🐐. He make story device have that problem 7 days need to reapir that parts came from japan 😅and u have to pay advance 😂.if u pay advance than now u fucked up now another stories came in film he will make u left right months parcel came from japan 😅but in custom asking for tax have to pay 25percent 😅then now u have to gave money or ur advance is loss😂. He play minds games pressure u .😂😂😂😂😂. Every indian technician stories
سلام مهندس خسته نباشید به عنوان یک همکار از ایران خواستم بهت بگم ما تو ایران به این کاری که تو با آرمیچر کردی می گویم ان کار😂خب یا دوبارسیم پیچیش کن یا فقط کلکتور شو عوض کن یا کلا آرمیچر شو نو بنداز ترکار
so after all that nonsense , it,s still sparking like a bitch . which means the armature is done ,and needs replacing .the only time sparks like that are ok ,is when a new set of brushes are put in ,and it quickly goes away ,as soon as the brushes bed in ,if it,s still sparking ,the armature is knackered ,just replace it .
First of all, don't buy a ryobi brand, it's the worst machines ever made, I've had nothing but trouble from them, rather a Japanese make, like Makita etc.

Amazing video… we want more!
THANKS FOR YOUR SHARING SIR
Ten wirnik po naprawie lepiej świeci niż ta żarówka. Proponuję z tej frezarki zrobić lampkę nocną
Exactly
Ova opracija sa šmirgl papirom je posebno delotvorna za kolektor, kolektor joj se toliko raduje kao da ti koristiš šmirgl papir umesto toalet papira
Za mała lutownica, trzeba było wziąć większą.
🙂
Given a choice you want a flat sharp tool (think tiny chisel) to clean out the commutator rather than a pointed one.
They make commutator draw blades just for that purpose. I got carried away once on a GM starter and went pretty deep. Sounded like a Mopar starter afterward....lol.Chinese-made router....commutators are cheap if available.
Thanks man that helps a lot
What was the result?!
It lights as same problem before any works!!
Thank you for this video! I have an electric lawnmower and the motor is arcing in a similar way to yours. I will try this repair technique👍👍👍
Try replacing the brushes first.
cuando se puede se puede .buena .
Tengo una cierra de mano y un esmeril Riovi con ese mismo problema y no consigo el mandril gracias por su explicación
I dont use sand paper.. I use fine plastic finger mail file or fine metal file.since brushed are even i want the contacts to be even as well send paper will help but better to use something solid like sanding block

Your grinder most likely has a “capacitor start motor”. The capacitor jumpstarts the motor to get it started. Replace that capacitor.
Your end plate bearings are worn out that's why the rotor magnetized by the stator. Replace it and it will go back to normal operation
What grit sandpaper did you use to file down the commutator?
What's with your test light,can you please explain how to make one.where are you getting the power supply from to the light
So interesting...So all the elongated commutator bars should be in contact. The ones that were not making contact indicated the fault ?? I don't know if I've accurately assessed what's going on here without technical knowledge hehe
Yes,you got it right
I don't understand I still see sparks after you did some soldering it didn't work?
some spark is normal too much spark is not at the begining it was sparking too much

Ryobi is a great piece of equipment...if you like entry level crap. I would rather do without an extra week and buy a real tool

It turned itself into AC :D

Is that router used for wood or concrete?

Are sparks present even after repairing the device?

Hi sir,about testing using the light bulb,how u connect the wire because at the video i saw u twisted the both of it.so i little bit confused which one positive & negative.
Itu bolak balik gk apa2.
Di uji dari tiap titik lilitan itu.
he probably doubled up on wires for both positive and negative

Your 115V test light is doing more damage than good, make a 12V DC test light...
hi how about where can i get the Test lamp
There is a device called a multimeter….
❤
I like this better
.. more fun 😂
@@crankfotton 🤣
This tool made sparks. Multimeters only give values and most of the times these values are very very close to each other, making it difficult to find where exactly is the short circuit in the commutator.
@@jorgecueto9649is this a short or has the wire snapped and it's arcing across the wires ?
This really needs audio commentary, it was arcing at the end so it looks to have failed?
all brushed motors do a little sparking
@@MyJootube This is what I was looking for, I just bought a rotary tool and saw tiny sparks, was wondering if it is defective, but this video seemed to show otherwise. It is when those sparks become gigantic that I should be concerned then.
Why there are marks on armature core
May be armature is touching with field core
Remove metal for balancing?
Title said how to find short? Did anybody learn how to find the short in this video? I didn’t…. 🥴

Check your field coils .... One is definitely short

And I thought I ha a Big soldering iron! I get it. The big iron transfers the heat quickly so you dont melt the isolative rosin or winding coating.
