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

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.

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!

[kingchris]

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.

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.

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

[masterprogrammer]

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.

Thanks for showing me that buying a new alternator is an amazing value.

[giffjp]

Very nice work. Thanks for taking the time to edit this to perfection!

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.

[Tuxlion]

Great video but poor job on actually showing how to repair. Things aren't explained and while Im all for showing instead of telling, I wouldnt know what Im checking for in the electronics or why you needed to replace those parts or what I would do if I need to replace or fix any of the other parts.

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.

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!

[MiniHp]

cool restoration, but id like to see a ground side voltage drop test under load on that puppy.

[jaswats]

"My alternator is broken!"
"What's wrong with it?"
"It's not orange!"

[georgegarside-dvxy]

someone that knows how to treat a car right. love to see it. in a throw away society i salute anyone who wants to love fix and repair. good stuff auto doc

[marcuswaterloo]

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

[freedoms]

It's the small things in life you can really appreciate and this is one of them. Love this

[NightWear]

Wow, the art of making shit better. That alternator is never going to die. This is so inspiring. A job well done.
