Super cool, but won't those bolts and screws be rusty within a couple of weeks? When you wire brushed them you took off whatever zinc coating (or other coating) they had. Cool stuff though 👍
20 years ago when I was in Highschool our auto teacher taught us how to rebuild alternators, break calipers and starters. Pretty good chance one was gunna go bad on our cars and we had no money. Im glad he did, I do it to this day.
You were taught about maintaining cars in highschool? Thats very cool. Where i'm from (Ireland) they teach us religion, irish and latin. Absolute bollox nonsense.
I was excited to start woodwork in year 9, start of the class my friend and I were pretending to duel with dowel rod... teacher banned us from ever doing the class and we had to take cooking instead, "you will NEVER learn woodworking because you're silly and irresponsible!!" Fast forward 15 years and we realised I was the carpenter doing his loft conversion
This is actually a super interesting lost process. When you needed an alternator in the Old days, mechanics used to rebuild them now they just replace them. Super cool to see this guy do it
This saved me on a 1990s rare alternator that could not be bought or replaced on an old JDM vehicle, I even found out I could use a different regulator in the body thanks to you and how to dissasemble it!! Thank you!
If you like having your cars in top condition and enjoy working mechanically you quickly find out that having tools and hobby is better than paying for gamble called mechanicall roulette. + no mechanic gives single sheet for tiny details... You can do it far more a better than some worker under time pressure. And no one gonna make things like replacing hardware with stainless where it makes sense
If you work on your own car your gonna have most of those tools. Soldering iron and multi meter you can get fairly cheap, you can get away with no press if you use a hammer carefully, a lot of parts shops offer rental for bearing pullers or ever let you borrow it for free for a day.
Cool video but I would offer one recommendation. When cleaning the stator core iron laminations always run your cleaning tool parallel to the laminations. If you run the tool across the laminations and accidentally smear some metal across the laminations you will short the laminations together potentially creating a hot spot in the core.
на самом деле эти пластины и так закорочены но дело в том что они хоть и закорочены но они не создают толщу в которой могли бы наводиться большие токи и заусенцы неиграют большую роль
Good video to be fair it's nice to see something rejuvenated instead of buying new so props to you for that the only slight thing is should of masking tape the mounting bracket as cars use the bracket as the ground, other than that it looks great though, I don't understand the folk that saying bad things , keep up these restoration type videos they are good to watch, and make a different change of pace
Once blew an alternator in shop class back in high scholl, like a big ol' dummy. My teacher made me go to an alternator shop to learn how to rebuild it. Was the best experience i had in high school. It began my love of all things electrical.
Good work. I did something very similar with mine. Just a note, the mounting point where it's connected to the engine bracket is actually a negative terminal, so you may want to sand off the paint from there. Otherwise, it will give negative through the bolts, which is not always good.

Freezing spray is a special product that quickly cools a metal surface when sprayed on it. Due to this, the metal contracts and the part becomes slightly smaller in size. This property is widely used in assembly work, including when installing bearings.
This was cool to watch. Seems a bit beyond my DIY ability. I'll definitely check this channel out more, though. Might be other useful vids for my VW. Thank you!
You can do it! I partially rebuilt my alternator on my 99 RAV4, I just mean replacing the brushes and regulator. Luckily my bearings were in fine shape but had I needed to replace them I could've. They sell kits online with everything you need .

I have some tools that are over 15yrs old and they are still in great/like new condition and it feels good to use them again and again. If you have interest in cars or general diy and you know you will be doing it then its good to have tools. I am at stage now where I can maintain all our vehicles incl my job van and it feels great to be honest. Of course if you can afford it go for a better equipment, but my point is you wont need top of the range latest pro tools.

I changed the alternator for my 2006 car several times in the past year, always buying used and reparing it, they always looked very dirty, only lately I ordered a new one Bosch online, everything has been expensive.

The labour alone would be far more then the cost of a new alternator. But the knowledge of how to service one could be very beneficial in the long run.
not a practical repair for most (requires pressing, soldering, not a guaranteed repair) and even if one has the required tools and skills a replacement may be more than worth their time. having said that, i love the idea of keeping something usable out of scrap, the video is great, and i love the black and orange paint! keep up the good work
The thing is that most of the parts like this you find online are refurbished original parts. Usually if it requires the old part in exchange for the new part, it's definetly a refurbished one.
Yes 100%. It is worth an attempt at repair for original parts because you know it worked at one point. The new parts you have no idea if they work or if they are going to go bad in 500 miles because manufacturing tolerances have gone out of whack these past few years. I also don’t want to wait months on a new OEM part. The 1 or 2 days this takes to do, to me at least, is worth it to avoid waiting 4 months on a $300 part.
Nice, just ordered my parts for my original Honda alternator. an aftermarket one i have on now works but gives a dashboard light so i'm going to try replacing the bearings and brushes on mine, it did still charge just rattle. Seeing an alternator being painted here never crossed my mind, it looks nice, might try it. replacing some parts comes out insanely much cheaper than getting a new one. the difference is 20€ vs around 1000€ excluding labour of course.
This particular brand of altenator (Mitsubishi) is a very common system used by many manufacturers like Suzuki, Honda, Mitsubishi, Mazda, etc. with different regulators, communication protocols and mounting ears , and it can have four main weakness: regulator, stator, rotor, and contact points. Regulators: all D-P pin marked regulators (com. protocol introduced by Mazda in the very early times) with the three pin layout connector are sensitive, and commonly die if the brushes making arcs, because of the wear and grooves of the sliprings. It's the same with the honda three pin connector C communication protocol regulators. The toyota type two by two pin connector regulators with P-D or C data communication and all other regulators with lamp outlet are very reliable and mostly survive the harsh conditions like induction and high voltage peaks from the slipring sparks. Stator: They use a special thin surface impregnation (black epoxy) on the stator dynamo plates, instead of insulating sheets. 1 of three of this altenators need a stator rewinding, because, as the plates corrode, they expand and getting closer to the winding loops at the edges and making a ground short circuit. Faulty, expanded, corroded stators are valuable, because there are no other good alternative for them to replace. Chineese, aftermarket stators has very bad quality, low quality copper and non ferromagnetic steel plates which gets them overheated and burnt all the time. The factory stators can be burnt out, cooled down on a supporting cylinder, corrected on the lathe and rewinded by specialist using insulating sheets inserted into the grooves. Rotor: the slipring-brush pairment is overall optimal on this altenator system, so sliprings often need just to be turned and polished on the lathe to remove the grooves. But, as the sliprings are bigger diameter then usual, they have a higher tangetial velocity so even small grooves on the sliprings can lead into brush sparking and popping, and that small thing makes the altenator bad. Always check brush twisted connecting wire for fatigue. In 1 out of 10 altenators the rotor coil outlet wires around the slipring soldering or inside the insulator tube corrode (green corrosion product is visible) and the rotor coil gets a wire break, which is often invisible, because it can happen inside the coil too. First case can be easely repaired if there is enough wire lenght left to make an extension. Always use FBS glue fillout to take off the centrifugal loads from the the soldered connection. Contact points: Inside the altenator the negative power diode bridge and the ground point of the regulator are making the ground contact directly through the internal aluminia surface of the back case. This promotes the contact corrosion of the backcase and it leads into regulator malfuncion and high internal voltage drop (low voltage charge output on the vehicles grid), so in mani cases the altenator needs to be cleaned at this contact surfaces to resurrect. Older Mazdas have the windscreen washer fluid filling hole near the altenator connector, so small leaks slowly corrode the altenator connector wires. My opinion on the video: rust removal and painting the stator is necessary to prevent the corrosion and expansion, but painting the inside oft the back cover is a mistake, and the ground contact surfaces will never make contact again.
This is pretty good... If you are doing a resto mod and trying to have your engine look like a piece of art... knowing this things sure helps. On a pratical stand for todays days it just isnt feasible as is more cost effective to buy a new one and put it than repairing or refurbishing an old one unless its one of a kind and you cant find new ones or used ones. A great video nevertheless.

You can pry and tap the rear housing and stator assembly first before you remove the pulley, this way you can hold the rotor and rattle off the pulley and you wont need a puller to remove the rotor from the rear housing. I would have replaced that slip ring instead of machining it unless you had a spare rotor, also get a bigger soldering iron. Even now i come across units that i rebuilt 15+ years ago i can tell they're mine because of the colour i would paint the stator, there will no mistaking your work in the future. Good job👍
My grandfather used to work at a gas station/auto repair shop back in the 70’s. He said when someone drove in with a bad alternator, they’d tell the customer “No problem! I’ll get you a new one. Be back in 30 minutes.” They’d take the bad one out back into the shop, disassemble it, clean it up like this video, and paint it with silver rally wheel paint to make it look brand new. 15 minutes to take it apart, clean it, and spray it after making sure it works. 15 minutes for the paint to dry. They’d come out to the customer with the old alternator and sell it as a brand new one. That’s one of the ways the shop made extra money.
as always, watch autodoc and you can do everything! I started fixing my own vehicle after years spent in garages and been lied by the "professionals". Thanks and keep going, we need more tutorials!

Thank you for your feedback! In the description of the video, you will find all the links to all the products in the video.
Hi! What are the products that you used?
Thanks for video!
Greetings!
n the description under the video there is a list of products used.
I also love bringing ‘broken’ items back from the dead. This was so good!
I love not wasting time or money on special tools I will only use once or twice in a lifetime.
Buy a rebuilt exchange unit with a guarantee.
@@davidparker9676 Good for you bro. No one asked.
@@C.J_the_Goat Maybe you can work on reviving your brain next. Just spray paint it orange and you'll become a genius!
Genuinely curious. What is the "freezer" spray and why do you use it?
Freezing spray is a special product that quickly cools a metal surface when sprayed on it. Due to this, the metal contracts and the part becomes slightly smaller in size. This property is widely used in assembly work, including when installing bearings.
This was cool to watch. Seems a bit beyond my DIY ability. I'll definitely check this channel out more, though. Might be other useful vids for my VW. Thank you!
You can do it! I partially rebuilt my alternator on my 99 RAV4, I just mean replacing the brushes and regulator. Luckily my bearings were in fine shape but had I needed to replace them I could've. They sell kits online with everything you need .
Primer is not necessary before painting? or you can just pait the alternator after cleaning it?
Was there an actual savings buy rebuilding vs buying a reman?
Now this is a true and real car mechanic. Everyone can replace part but only true mechanic can repair it.
There is the minus going to be connected? Looks like all parts contacting the metal of the car are now painted. Did you leave out a spot for that?

1:05 impact driver it set wrong way. can snap bolts over tightening them.
Great work‼️?Did cleaning it fix the issue. Or were there part replacements?
All details that required replacements were replaced.
Man...if you have the tools , the time and the working area , there's nothing you can't do... excellent workmanship...!
I wonder if even after all that work, will it still create a charge?
Do you need heat-resistant paint or a classic one? Thank you
It is better to use heat-resistant paint.
could you soak the housing in a ultrasonic parts cleaner?
Thanks for your comment! Give this cleaning method a try. The video shows an easier way to do it.
BRO ABSOLUTELY OUTSTANDING WORK U R THE BEST JOB WELL DONE
this is just cleaning it and replacing the bearings, it wasn't broken, what do you do if the coils are burnt?
What is the average cost of having someone repair an alternator, and how long will a repaired one last on average? Great to watch this man work.
it was an awesome video but i have a question that I would like to ask you about it. most of the videos confuse me about this. a part like this is located under the hood which can be hot sometimes. does that burn the paint? how long does that paint last? does it burn due to the heat in the motor?
everything was perfect in the video by the way.
Hello! The hood does not heat up to such a temperature that the paint on it is damaged.
@@autodocuk how long do you expect the paint to last?
Beautiful job bro. Amazing. Please what is the Color code name for the orange paint used?
Thanks for your feedback! This manufacturer does not have paint codes, but you can select the color using this link: www.autodoc.co.uk/car-care/automotive-paints?TH-cam&
AutoDoc, I'm rebuilding my alternator but I don't know where to get a new Rotor from for my M35 Infiniti alternator. Any suggestions.

Are the wires supposed to turn black?
I love that ya'll do these videos but its almost like it would be cheaper to buy a new alternator if you don't have these tools to do the job.
If you work on your car you will have most if not all of these tools, incl bearing puller, not expensive anyway. And tool collection grows with times.
@@bluewanderer9903 sooo true man, I'm currently building my range and am looking forward to when i can say yup got all of em, instead of now where I'm like damnit, refer to comment above. :P Appreciate your response lad.
@@cephasgunn1993 it will all add up you'll see, you dont need to go mad spending neither, buy as you need or as job requires. And even cheaper tools will last you forever since you wont be taxing them every day all day long. I have some tools that are over 15yrs old and they are still in great/like new condition and it feels good to use them again and again. If you have interest in cars or general diy and you know you will be doing it then its good to have tools. I am at stage now where I can maintain all our vehicles incl my job van and it feels great to be honest. Of course if you can afford it go for a better equipment, but my point is you wont need top of the range latest pro tools.
When it comes to sockets I would highly recommend quality impact set rather than cv if you use impact gun, which again can be gotten cheap enough.
@@bluewanderer9903 I'm based in the uk, do you have any brand suggestions for the quality end of budget there man, I know what you mean as far as using tools for multiple jobs though, I rebuilt and replaced my rear subframe on my 02 passat and originally bought the tools i needed to do the brake rotors and pads, luckily the 18mm was also what i needed for the subframe bushings felt great i didnt need to get more for that job. most of my kit is teng tools but they can be pricey so i am tryna get other proven companies by suggestion of folks who love to do their own work like myself.
@blue wanderer I work on my car but I don't have a bearing puller yet or bushing press out. how do you press a bearing in without a hydraulic press ?
So satisfying seeing the body get cleaned ❤
Excellent work but this is work for a professional not for DIY , better to buy a new one :)) Thanks for the video!!!
This was really satisfying and fun to watch.
He fix the contact and gave a treat to the shell. Thats why it worth. If he had to rewire the coil probably it wouldn’t compensate
looks nice but for some reason i feel like you should prove that it actually works after getting it back together?
I changed the alternator for my 2006 car several times in the past year, always buying used and reparing it, they always looked very dirty, only lately I ordered a new one Bosch online, everything has been expensive. When i watched this video now i was thinking how were they repairing it and why don't they repair the ones they sell as good as in this video... Bravo
We appreciate your feedback! And we are pleased to know that you liked our video.
Виглядає гарно, але ви зробили цей генератор не робочим. Ви завфарбували геть всі точки масси). Регулятор не запустить генератор бо він не отримає мінус. При нагріванні генератора краска злетить. Відео як інструкцію , як відреставрувати генератор, не можна дивитись. Відео лише для зорового кайфу.

The amount of work, skills and parts that when to this. It probably cost more than a new one
The labour alone would be far more then the cost of a new alternator. But the knowledge of how to service one could be very beneficial in the long run.
What are you going to do about the ring contacts?
Thanks for your comment. We are constantly working on improving our videos. Contacts need cleaning.
not a practical repair for most (requires pressing, soldering, not a guaranteed repair) and even if one has the required tools and skills a replacement may be more than worth their time.
having said that, i love the idea of keeping something usable out of scrap, the video is great, and i love the black and orange paint! keep up the good work
This video is for informational purposes only.
Nice job
I always prefer to repair the original part instead of replacing it with an aftermarket even more if it's the alternator or starter motor
We are sure that your comment will be useful for many of our viewers.
The thing is that most of the parts like this you find online are refurbished original parts. Usually if it requires the old part in exchange for the new part, it's definetly a refurbished one.
Yes 100%. It is worth an attempt at repair for original parts because you know it worked at one point. The new parts you have no idea if they work or if they are going to go bad in 500 miles because manufacturing tolerances have gone out of whack these past few years. I also don’t want to wait months on a new OEM part. The 1 or 2 days this takes to do, to me at least, is worth it to avoid waiting 4 months on a $300 part.
Nice, just ordered my parts for my original Honda alternator. an aftermarket one i have on now works but gives a dashboard light so i'm going to try replacing the bearings and brushes on mine, it did still charge just rattle.
Seeing an alternator being painted here never crossed my mind, it looks nice, might try it.
replacing some parts comes out insanely much cheaper than getting a new one. the difference is 20€ vs around 1000€ excluding labour of course.
Thanks for your feedback! We are glad that you liked our video.
Wow! The repaired alternator looks expensive than the original.. "Sana All"!
This particular brand of altenator (Mitsubishi) is a very common system used by many manufacturers like Suzuki, Honda, Mitsubishi, Mazda, etc. with different regulators, communication protocols and mounting ears , and it can have four main weakness: regulator, stator, rotor, and contact points.
Regulators: all D-P pin marked regulators (com. protocol introduced by Mazda in the very early times) with the three pin layout connector are sensitive, and commonly die if the brushes making arcs, because of the wear and grooves of the sliprings. It's the same with the honda three pin connector C communication protocol regulators. The toyota type two by two pin connector regulators with P-D or C data communication and all other regulators with lamp outlet are very reliable and mostly survive the harsh conditions like induction and high voltage peaks from the slipring sparks.
Stator: They use a special thin surface impregnation (black epoxy) on the stator dynamo plates, instead of insulating sheets. 1 of three of this altenators need a stator rewinding, because, as the plates corrode, they expand and getting closer to the winding loops at the edges and making a ground short circuit. Faulty, expanded, corroded stators are valuable, because there are no other good alternative for them to replace. Chineese, aftermarket stators has very bad quality, low quality copper and non ferromagnetic steel plates which gets them overheated and burnt all the time. The factory stators can be burnt out, cooled down on a supporting cylinder, corrected on the lathe and rewinded by specialist using insulating sheets inserted into the grooves.
Rotor: the slipring-brush pairment is overall optimal on this altenator system, so sliprings often need just to be turned and polished on the lathe to remove the grooves. But, as the sliprings are bigger diameter then usual, they have a higher tangetial velocity so even small grooves on the sliprings can lead into brush sparking and popping, and that small thing makes the altenator bad. Always check brush twisted connecting wire for fatigue. In 1 out of 10 altenators the rotor coil outlet wires around the slipring soldering or inside the insulator tube corrode (green corrosion product is visible) and the rotor coil gets a wire break, which is often invisible, because it can happen inside the coil too. First case can be easely repaired if there is enough wire lenght left to make an extension. Always use FBS glue fillout to take off the centrifugal loads from the the soldered connection.
Contact points: Inside the altenator the negative power diode bridge and the ground point of the regulator are making the ground contact directly through the internal aluminia surface of the back case. This promotes the contact corrosion of the backcase and it leads into regulator malfuncion and high internal voltage drop (low voltage charge output on the vehicles grid), so in mani cases the altenator needs to be cleaned at this contact surfaces to resurrect. Older Mazdas have the windscreen washer fluid filling hole near the altenator connector, so small leaks slowly corrode the altenator connector wires.
My opinion on the video: rust removal and painting the stator is necessary to prevent the corrosion and expansion, but painting the inside oft the back cover is a mistake, and the ground contact surfaces will never make contact again.

What foamy product was that ? A degreaser ? and before it was just water ?!
First, it was an engine wash and then an active foam car wash.
"My alternator is broken!"
"What's wrong with it?"
"It's not orange!"
Is it supposed to turn black that way?
Really enjoyed this, can you make one for a VW Touran alternator and starter motor... and sell all of the parts and tools?
Thanks for the clarification, we’ll think about what we can do with this in new videos.
This is pretty good... If you are doing a resto mod and trying to have your engine look like a piece of art... knowing this things sure helps. On a pratical stand for todays days it just isnt feasible as is more cost effective to buy a new one and put it than repairing or refurbishing an old one unless its one of a kind and you cant find new ones or used ones. A great video nevertheless.
I think it was more fun watching you do it. Cant see myself rebuilding an alternator anytime these days anymore
Buongiorno se volessi rigenerare l'alternatore della mia mk5 2017 ? Cosa spendo?
Un trabajo minucioso y excelente! Solo haría algo así para un coche de exposición, aún así muy buena atención al detalle 👍
Muchas gracias por la reseña.
I wish this would become the norm again, instead of just throwing away ur old worn stuff, refurbish it! Dx
This was an amazing video
WOW - a 10 of 10 !!!! Great Work!
Was that powder coat on the alternator?
Man i just need to know how i plug my ridex regulator back into my valeo motor... where does the extra cable go, oem didnt have it..........

He has a cool tray he spays everything down on! I wonder if it’s a parts cleaner or just a tray
You can pry and tap the rear housing and stator assembly first before you remove the pulley, this way you can hold the rotor and rattle off the pulley and you wont need a puller to remove the rotor from the rear housing. I would have replaced that slip ring instead of machining it unless you had a spare rotor, also get a bigger soldering iron. Even now i come across units that i rebuilt 15+ years ago i can tell they're mine because of the colour i would paint the stator, there will no mistaking your work in the future. Good job👍
Thank you for the clarification. We are sure that your comment will be useful for many of our viewers.
My grandfather used to work at a gas station/auto repair shop back in the 70’s. He said when someone drove in with a bad alternator, they’d tell the customer “No problem! I’ll get you a new one. Be back in 30 minutes.” They’d take the bad one out back into the shop, disassemble it, clean it up like this video, and paint it with silver rally wheel paint to make it look brand new. 15 minutes to take it apart, clean it, and spray it after making sure it works. 15 minutes for the paint to dry. They’d come out to the customer with the old alternator and sell it as a brand new one. That’s one of the ways the shop made extra money.
Thank you for sharing your story with us!
as always, watch autodoc and you can do everything! I started fixing my own vehicle after years spent in garages and been lied by the "professionals". Thanks and keep going, we need more tutorials!
Thanks for your positive comment! Stay tuned with us!
hi what spray is he using after he sanded the components
We have used an engine cleaner and you can have a look at the options and choose the appropriate one at the following link: www.autodoc.co.uk/spares-search?keyword=Engine%20Cleaner
How painting it did fix it?
my coil caught fire and melted, how can i fix it?
