Alternator Rebuild

- Having switched out my OEM alternator for a high output replacement it is a good idea to keep a spare in good working order for when the need may arise. In this video, I'll tear down the old OEM alternator and rebuild it with new parts to keep it in like new conditions. The idea being to keep this in the truck in case the non-OEM HO alternator decides to fail in an inopportune time.
Notes:
22mm nut on pulley torqued to 81 ft-lbs
List of all part numbers:
27370-75060 Brush Assembly
27388-42010 Brush Cover
27443-63020 Bearing Cover
90099-10140 Bearing (rear)
90099-10192 Bearing (front)
27064-42010 Seal Sub-assembly
27384-50030 Washer
27387-42021 Insulation Washer
27389-42010 Terminal Insulator (need 4)

I'm not even looking to rebuild and alternator and you had me watching from start to finish with your EXCELLENT step-by-step instruction with very helpful commentary all along the way. Practice this method and your channel and you'll grow exponentially, as others are lacking in this type of quality production.
Thank you for the kind words and your time watching my video. Cheers 🍺👍
Gunna be doin this myself pretty soon. All the parts are showing up sometime this week. Thanks for the walkthrough!
You bet!! Thanks for checking out the video 👍
Can you show us how testing and ready to install it, very good video and professional.
Excellent lesson.
Thanks for watching👍
Where can I find parts to rebuild the alternator for a 03 Honda S2k?
Great job there! I'm currenly replacing both bearings on an alternator a lot like yours if not the same....I root caused an annoying sound to those bearings...but now I dunno...Anyways, my question to you if I may is what is the purpose of that little washer you replaced in front of one of them bearinngs? I mean, I don't have it new and wonder if that was the source of the annoying sound at start up....would it be ok not to place it at all? I could always reuse the old one anyhow... Cheers!
It very well could be your cause. Thanks for watching 👍
@@WeekendWrenchTurner do you think it’ll be ok if I don’t use to reassemble the darn thing? The washer I mean…
Process of elimination. Replace everything you can and hopefully it will work once you have done that. Personally, I would troubleshoot the alternator and fix whats wrong with it.
Yeah, I didn't really go over why I did this, but it is for a trail spare. I just wanted to have a known good OEM alternator as a backup 👍 Thanks for watching 🤟🍺
How do you troubleshoot the individual parts?
A trail spare?@@WeekendWrenchTurner
Thanks!
Great video bud! I did notice a leftover screw on the bench tho.
JK. 😆
How much will I generally spend for all the parts to do a complete rebuild like this? Is it a kit you buy?
And how long does it take generally, about 3 hours?
These questions will determine if it's worth it to me to spend the time to rebuild one myself.
And what is the most common problem as to why an alternator even "goes out"? Is it the brushes? or can it be the rectifier or the regulator? Don't those need to be tested to find out if that's the actual reason it croaked?
If I recall, at the time it was about $65 for parts. Pretty sure I got them with a bunch of other parts from Partsouq, so shipping wasn't bad overall.
@@WeekendWrenchTurner , it's not that hard really after watching your vid. But for an extra 100 bucks I'll let some chinaman build mine. 🤣
If you have a huge press machine, you’re in business lol
You can find those for under $150 usually at harbor freight!! Thanks for watching🍺👍
I've replaced bearings and racers on my boat trailer. Basically you just need a hammer and a socket like he did on some steps. Easy shmeasy. Gentle tapping is all that's really necessary. But a press is nice!
How did you know if the other parts were still good. It seems like the main reason to take it apart was the bearings. Obviously you replaced a few washers and insulators.
This was a good alternator before hand, that I wanted to refresh as a rebuilt spare 👍
Maybe tell your viewers that information at the start? Good video@@WeekendWrenchTurner
Very good video sir, but you need a new camera, this camera HATES to focus 😂😂
Cell phones are not the best for this...😂😂
Where did you get all the parts? The dealer seems not to have all of them available anymore
I've found that PartSouq to be the best site to get stuff. You have to plan for shipping though, as even just a few items will cost a bunch to ship.
Good video !
Thank you sir🍺
Great video and straight forward, thanks.
Where do you get all replacement parts?
I've found waiting for a few mods/fixes and then ordering from PartsOuq.com makes shipping work out better than my local dealer. Small stuff I just source locally. Good question 👍
check wirings and terminals before replacing the alternator as well.
mine was cracked battery terminal, why it didn't get charged
Excellent advice 👍🍺 Thanks for watching 🤘
You can test by unplugging your battery while car is running.
@@Ryahoeee Another great tip👍🍺
You all used OEM replacement parts? Any recommendations on aftermarket replacement parts that work "just as well" like from denso/aisin or something?
My 4runner is just a DD beater type of vehicle. I don't need everything to be best of the best if you know what I mean
Denso and Aisin would be considered OEM on these, so they're perfect🍺👍
Are the parts used for rebuild universal for any alternator?
I'll certain that they would be different for different manufacturers. Maybe some Denso models share parts, but I'm not sure which ones would 👍
How did you know what parts you need and how did you get the part number? I have a 2006 corolla Denso alternator part number is 210-0395
I always use this site to look up parts: japan-parts.eu/toyota
What about slip ring
Not sure which piece you mean by this 😕
where did you get that puller from?
That's from the cheap harbor freight three jaw puller set if I recall correctly 👍
www.harborfreight.com/three-jaw-puller-set-3-pc-63953.html
which website did you order your replacement parts from?
Most the time I price things out and even after shipping, since I bundle projects, it's cheaper at partsouq.com/ #notsponsored
@@WeekendWrenchTurner do you know of a place in the usa
I'm always comparing prices to Camelback Toyota out of AZ. They are always great to work with🍺👍
Do you add grease to the bearings before put them inside their final place?
They are sealed bearings, so they don't need to be greased up, but I do put a little tiny bit on the outside race to help them go in 👍
@@WeekendWrenchTurner thank you for the reply. I don’t have a press like yours but I could take the bearings out… I have no idea how I will put them back in 🤣
do you have the model number for your press?
It's the standard harbor freight 20 ton h frame press. Use it all the time!! 🍺👍
How much did this kit cost? Where can i buy the kit
I pieced this kit together from the parts list in the description and then purchased them from partsouq.com. All in, I think it was right at $100. Thanks for checking out the video!
@@WeekendWrenchTurner Thumbs up on the rebuild. I think it's sad it cost that much. The world has truly become a disposable, wasteful.... Use to change brushes in tools, re-sharpen, tubes in TV's. Now its throw it away a new one cost the same...sad!
@@WeekendWrenchTurner, My GMC alternator is rated at 105 amps. I'm getting a "new" one (not reman) off rockauto for $152 shipped. Plus the amps are upgraded to 258. This is all doable, but personally, I just don't think it's worth the effort to rebuild it myself if the parts are $100 bucks.
What exactly model of puller did you use here? Could you provide a link?
If you're talking about the one at the 8 minute mark or so, that's the generic harbor freight three jaw puller 👍👍
I could not find the parts for my Jeep except on eBay I think they are cheap Chinese parts.
Now I need to find a video on how to do this without a shop press. Good video otherwise.
You could probably get away with an arbor press. 20 tons is a bit overkill I admit. Thanks for watching 🍺👍
Maybe the local auto parts has a puller I can rent to get the bearings off. Will find out in a few hours. @@WeekendWrenchTurner
Let me know how it goes 👍👍
I was able to get the bearing off using two long pairs of needle nose pliers. I pried up between the cooling fins so as not to damage them. I sort of hit on the pliers like I was trying to pop the bearing off and it worked after about 8 slams on the plier handles. Two long screwdrivers could also work as pry bars and pop it off being careful not to damage anything. There is room under the bearing to try a puller but the one I have wouldn't work.
Good job!! Sounds like it would frustrate me, so kudos for getting after it 🍺🍺
Was that a Milwaukee impact driver or impact wrench?
I believe I was using the impact driver in this video with an adapter for 3/8" sockets 👍
Bad idea to use the puller on the housing it can easily crack
next time time just bang the alternator shaft on a flat surface
That's a good tip 🍺 Thanks for checking out the video👍
Wtf happened @2:42 to 2:43!!??
I skipped over to having the cover off, but am still describing the same piece. Sorry for the confusion, and thanks for pointing it out👍🍺
Could i pay you to repair mines
I wish I had the shop that would allow for that. Thanks for watching!! 👍🍺
Penetrating oil would make your work much more, uhhh, civilized….
Rebuilt ones arent expensive i cant see wasting time ordering parts and doing that
I've got a 150A one on the truck and use this one as my trail spare. I wanted to make sure that it was in good condition should the need arise. Thanks for checking out the video👍🍺
read reviews on rebuilt. they are mostly crap.
Must have gotten a cherry then, it's been going strong for nearly 10 years now🤟
I can't even unplug the socket at the back to get it out of the vehicle.
