Excellent
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 👍
I would replace all the screws but other than that it’s great.
Very nice video , I like your detailed videos and excellent work methods like with the freezing spray
More of these please!
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
Old days? I knew a guy who paid his way through NADC, Nashville Auto Diesel College, rebuilding starters and alternators. Which he learned how to do while attending NADC. This was maybe 16 years ago. People can still repair starters and alternators. Problem is not many people want to. Whether it's having it rebuit or rebuilding it. Easy way is the best way is the slogan of today.
Thank you for sharing your opinion with us.
@@superbeast8373 It’s just how there used to be radiator shops everywhere you look, people would just fix your radiator, now you just buy a new one
@@JoshHookerJoshhook123 People still do it. It's just usually small speciality shops and independents working out of their garage. It's sad tbh. Great for big companies. They're making a killing. Crap for the environment though. I'm not a tree hugger or anything. But it's not sustainable.
@@superbeast8373 yeah that's their point. you cant get it done anymore cuz no one wants to do it.
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.
Thank you for sharing your story with us!
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.
@@kd2239 lol, it’s very common in the US to have woodworking, automotive and small engine classes.
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
Nice, do you think rectifiers and other parts need to be replaced? Or can be cleaned properly and the alternator would start working again.
This is beyond most people's ability. In fact most do not have all the tools, the press or the vise. I appreciate the work that went into it.
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
@@boobrowsky 100% true.
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.
Was thinking the same thing, Maybe advanced diy
If you don't have a vise in your shop then go out and get one right away. They're indispensable.
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!
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
Thank you for your opinion, we will take your advice for future videos.
@@autodocuk not a opinion when it is infact a earthing point that you've insulated... 😉
@@tcollogan some alternators have dedicated ground wires, but good point
@@tcollogan LOL! But it is orange, so that is worth an extra 100 horsepower.
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.
thanks for the tip, I will keep this in mind if I ever attempt this
We are sure that your comment will be useful for many of our viewers.
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
Thanks for showing me that buying a new alternator is an amazing value.
Thanks for your reply!
Very nice work. Thanks for taking the time to edit this to perfection!
Thank you for sharing your opinion with us.
Only thing AD can do perfectly xd
Painting "ground" connections is a lame thing to do. No "perfection" here.
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.
We are sure that your comment will be useful for many of our viewers.
It's the small things in life you can really appreciate and this is one of them. Love this
Bravo mate. Love these style videos; no stupid music. No long back story. No bullshit. Just straight to the point. Fantastic amsr sounds. Excellent filming. Attention to detail. Love it.
I would love to speak with you about possibly having you rebuild an alternator for me.
Unfortunately, we do not have a service station and we do not provide auto repair services.
What I am really starting to love about this crazy rebuild journey I am on “M54 E46” is when I want a rebuild video for a part it is there. Nice video Autodocs
cool restoration, but id like to see a ground side voltage drop test under load on that puppy.
I wonder why the video creator didn't "favorite" your comment?
When your alternator is painted orange, you don't need grounds.
In our video, we have demonstrated the basic steps to repair a generator.
This video is for educational purposes only and does not guarantee a specific result.
@@autodocuk If it is for educational purposes, why don't you show how to do it right?
Nobody needs an education of the wrong way to do things.
To add insult to injury, inexperienced people will watch your video and repeat the process you demonstrated, resulting in poor grounding issues.
This is so cool for you to make and share. The work shows that it's possible to repair, but also shows why it's a rational thing to purchase new. Not many part shops would show you in detail how to save cash, instead of just explaining why it's difficult, you show how and why. Thanks!
Thanks for the clarification, we'll think about what we can do with this in new videos.
This is complete overkill but very educational and interesting.
Loved it.
We are glad that this video was useful to you!
"My alternator is broken!"
"What's wrong with it?"
"It's not orange!"
Is it supposed to turn black that way?
Wow, the art of making shit better. That alternator is never going to die. This is so inspiring. A job well done.
Wow! The repaired alternator looks expensive than the original.. "Sana All"!
That’s pretty dope, now I want to do that to my alternator.
Skip all the other steps, just paint it orange.
We are glad that you enjoy our work!
Both the craftsmanship and the video editing skills were on point, very entertaining to watch! Also very informative, I have to replace the bearings on my alternator soon, this will be a good reference
I think it was more fun watching you do it. Cant see myself rebuilding an alternator anytime these days anymore
I came here to study rebuilding an alternator for my Dodge Ram 1500 work truck. While I can afford a new one, I just knew there was a more affordable way cost wise; not sure if it’s more efficient time-wise. Nonetheless, I think I will buy the new alternator, and learn to rebuild the old one using this video and others. I’m even considering pulling the new one after the rebuild, and just use the new one as a backup.
This was a satisfying watch start to finish. I think the only skill I like at this point is soldering which I can acquire with some training as well. Lastly, I’d need to acquire a few of the tools he used that I don’t have, but most everything else is covered. Thanks for the vid brother; straight to the point, and great visuals and title guides, oh AND NO TALKING 😂!!! Gained another subscriber.
Extremely intricate. Needs a lot of practice and accuracy. Thanks for this presentation
Thank you for sharing your opinion with us.
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 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.
So satisfying seeing the body get cleaned ❤
3:10 looks like some Star Wars space crap you’d find on Tattoine
it was a blast watching the whole video, very well done editing congratulations.
Thank you for sharing your opinion with us.
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 .
WOW - a 10 of 10 !!!! Great Work!
Now this is a true and real car mechanic. Everyone can replace part but only true mechanic can repair it.
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.
@@J_P_33 Maybe you can work on reviving your brain next. Just spray paint it orange and you'll become a genius!
I wish there was a place where I could get the same quality service where I live :(
We are glad that this video was useful to you!
Aye! This was very interesting! I've been using your videos for my VWs for quite a few repairs now. Respect from Daytona Beach Florida!
We are glad that this video was useful to you!
Great video AutoDoc! Thank you
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
Some people really have plenty of time to restore their alternator 😊
And now it does not work since the ground is through the alternator body and it is covered in paint?
Isn't the body made of aluminium?
@@uranusneptun5239 indeed it is made out of aluminium alloy and often the engine block too which it is attached to. The engine is grounded with a wire and that is the only ground the alternator uses. All the contacting surfaces have to be fairly clean between the engine and the alternator and between all bolts and alternator.
yes, exactly..at last someone nose shit;
I really wish you would say what products were being used (like the detergents)
Great video. I love the attention to details.
Excellent work but this is work for a professional not for DIY , better to buy a new one :)) Thanks for the video!!!
Great video! DIY repair for AC compressor if possible please!
I think there's a problem that will happen because the negative can't be conducted well because of the paint.
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.
This is a complete blast!!!
We are glad that this video was useful to you!
I'm watching this and I don't even have an idea what's an alternator is, RUclips just recommended this to me, even though I don't own a car.
Amazing job sir....realy fascinating to watch you do that....
this video makes me feel i can do a rebuild myself. saving me a ton of money.
Ahhh This video is super relaxing. It's pretty much ASMR😁
love this video rather than the parts exchange video. 👍🏻👍🏻
very nice...thank you
very insightful
Stunningly good work, enjoyed watching it!
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
Satisfying to watch. Silence is under rated.
Thank you for sharing your opinion with us.
Neat i like it when parts get re-used :)
This guy is good new techniques to all car enthusiasts
Great detail.
Good job👍
Beautiful work
Amazing thank you for help!!!
Brilliant. So much better than throwing it in the trash.
Great video thanks for all the effort. I was wondering why you didn’t use grease when pressing in the new bearings?
One of the best and most helpful RUclips channels out there.
Thank you for sharing your opinion with us.
For those of you that don’t know. This is what we call a remanufactured or “remaned” alternator
We are sure that your comment will be useful to many of our viewers.
Love watching this but given the amount of time, it's cheaper to pay a mechanic to replace it. This guy just made that look super easy when most people struggle just to change a tyre.
More work than I would ever do on an alternator. But can't argue with the end result. It looks great.
We hope our videos were useful.
Sick turbo you got there
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 ?
Дружище попробуй пескоструем сбивать грязь и ты удивишься на сколько это быстро и легко.
Это делал маляр, а ты предлагаешь ему остаться без работы.😀
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.
maladec;
Ну хоть один человек понимающий в вопросе.
This had to have taken 3 hours, with a shop rate of $75/hr that's $225 plus rectifier cost, bearing cost, nrw hardware. This is an enthusiasts job
Piece of art
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!
I mean an alternator is so cheap already that if youre gonna replace the internals for 70% of the cost of a new one, you might as well just swap the whole thing so some other small piece among your old internals doesnt force you to have to do this job again.
Excellent job and inspiring ❤
The Alternator is like a neglected child under the hood
Great video idea! Especially since the alternator I ordered from Autodoc was defective right out of the box!
Hello GrungeRock,
Thank you for commenting our video.
We are sorry you received faulty generator and we would like to help you.
Please, specify your customer and order IDs on help@autodoc.de and don't forget to mention what issue occured (faulty generator).
We will request pictures of it and we also need to know if it was mounted.
Don't be worried about it, we will find a solution together!
Best regards,
Your AUTODOC Team
this is just pleasing to eyes, but in reality replacing would be more cost effective!
great job
很棒的维修， Thanks for sharing
Now this is a video! Congrats :)
Alternator Story Time: Had a 1986 Pontiac Firebird once. One evening going down the highway, the faster I went, the brighter the lights became. I limped the car home, going slow, as to not burn everything up. I took the alternator out, replaced the voltage regulator and the same thing happened? NAPA said the "new" voltage regulator I just bought from them was bad 🤔 so I purchased another voltage regulator. The alternator worked just fine after that. Definitely time consuming doing the repair twice!
This was one of those "satisfying to watch" videos. I was also wondering how the brushes were going to be kept out of the way.
When it comes to cars sometimes "just buy a new one, it's more economical on time and money" is not the primary motivation, classic cars for example. You'll need get a penny back on it but a well/lovingly restored car with original parts, for me, is the sign of a good restoration.
A new is probably more expensive than a rebuilt one and on the rebuilt these days quality is iffy than the original
Well done, proper way of up cycling 👍
We are glad that you enjoy our work!
And it's better to recycle, re use, repair vs discarding and buying another alternator. Better for the environment. More sustainable and less shit in landfills. Again bravo.
Thank you for sharing your opinion with us.
Alot of parts arent available anymore for old alternators. Had to source a complete replacement for mine since the rebuildable parts are non existent!
Wooooow! Just wow!
I don't even have a car, but i enjoy this 😂
We are glad that this video was useful to you!
This is my fathers line of work
He is retired now but occasionally he rebuilds things like this
I asked why, and he answered: "to keep my mind sharp"
Actually right now he is working on a generator and an alternator for a small fishing boat
Behind him is my cousins motorcycle, waiting to be repaired
Simplesmente ótimo.👏👏👏👏👏
Nice work
Nice job
Awesome work
Professional guy
Awesome video! Makes me wanna rebuild by alternator. lol.
Thank you for sharing your story with us!
Man...if you have the tools , the time and the working area , there's nothing you can't do... excellent workmanship...!
Super Professional B I G Thank you Auro Doc Team✌🤩
