Do any of you guys still mess with rebuilding your 1g 100 amp alternators? I have one that doesn't work and is the original alternator to that truck so I would like to rebuild it, I haven't rebuilt an alternator since the 1990's but I used to be quite good at it. Where is a good place to get a rebuild kit? You used to be able to get a basic bearing and brush kit from autozoo for ~$20 or a master kit for $35 now I can only find individual parts. I do not want to do a 3g swap on this particular truck because it's all original, I know that's the best way but I would rather stick with what is stock and repair it myself. Any help is much appreciated. Thanks

 

yeah most the local parts stores no longer carry kits except for Chevy... you can find them on FleaBay and Amazon...

Summit and ASP Wholesale are a couple others RockAuto only has individual parts now too, it's been a while since I searched JC Whitney <<== they pretty much a dead end anymore.

EDIT: BTW most rebuild shops don't buy kits either they just stock a bunch of common Bearings, Brushes, Regulators, and Common Diodes/assemblies.

 

Change it over to a 3g and be done with it. That eliminates the voltage regulator. It makes 130 amps easy. It’s not hard to do.

x3 the large case 1g isn't worth the effort.

 

Funny, I tried to rebuild mine just today. Mine's the old style, but is stamped 70a.. I thought these were typically 60a, but Idi..

Anyway, along while ago, I ordered brushes and bearings that were supposed to fit, from rockauto.

Nope, the brushes were kindof nearly close, but in the alt they are contained in an integral brush holder, the replacements had bolt eyes, and though were kindof close, but no not at all..

I knew my alt was noisy and needed rebuilt, but I was really surprised it was working so well at all once I pried it apart and had a look inside.

One of the 2 brushes was gone entirely, grounded tab, with the exposed wires just falling onto the stator. The other brush was 1/16 of nothing and fell out in pieces.

The stator in wore from the dangling wire lead arching contact, and the bearings are like grinding a bag of bones.. But, it was still working fine, and has probably has a shift tonne of miles on it.

I'm gonna get a replacement at the jy, going for the same 2g model, and will gut the one I have for spare parts. These electrical parts are probably what a rebuilt unit would skimp on. I'll open it up, look for a good stator, healthy brushes, and smooth bearings, If it's not motorcraft, I'll probably put this rectifier, coils, or other parts on that decent case.

I like the durability of this old alternator, the new ones might be good or better, but this'n run many miles and I'll keep this style just because it ran hundreds of thosands for years and I like it.

If you buy brushes or a kit, don't open the alternator on a day you only have one and need it to get somewhere, too bad they couldn't make a kit that fit right, I'm gonna call and email them and tell em not to market this to fit this model, and make something that does if they want to sell a product.

 

ya'all bring up the 3G alternators .. while I guess they are OK ... it wasn't what the OP asked and he stated why he didn't want to upgrade... Personally I get that.

my truck came with a Pair of LN Alternators and I have the 300A LN single in use but it also doubles as a welder using the Lestek controller, so I would not upgrade to a 3G either.. IF anything I would just install the original Brackets and run the Dual LN again.

the single that I run keeps the 4 House batteries up to par too... 2 of those I use in the boat for the Avionics and Trolling Motor

IF you really wanted to do something then a Capacitor Bank for starting would be a Good start ... Pun intended.. I just cannot afford to go there.

 

Normally I would just 3g swap it but as I already said I want this one to stay original since it is completely un f***ed with, it still has the plastic cover over the studs of the glow plug relay and the black plastic cover over the fuse box that tells you what all the fuses go to... I have never seen a bull nose Ford that actually still had a fuse box cover until I acquired this one. Plus i honestly want the satisfaction of rebuilding that original alternator myself, it gives a sense of accomplishment when you do something like that which most people today view as a waste of time simply because they don't have a clue where to even start a job like that. When I came through tech school we were taught to rebuild everything that was rebuildable and personally I want to get back into rebuilding parts rather than replacing them.

 

Amen to that..... I 100% agree .... BUT See we are Green Now and we don't fix things we just Toss it in the Dump and Upgrade it

More Folks Need to be Green


Being Green
Checking out at the store, the young cashier suggested to the much older woman, that she should bring her own grocery bags because plastic bags weren't good for the environment.
The woman apologized and explained, "We didn't have this 'green thing' back in my earlier days."
The young clerk responded, "That's our problem today. Your generation did not care enough to save our environment for future
generations."She was right -- our generation didn't have the 'green thing' in our day.Back then, we returned milk bottles, soda bottles and beer bottles to the store. The store sent them back to the plant to be washed and sterilized and refilled, so it could use the same bottles over and over.

So they really were recycled.But we didn't have the "green thing" back in our day.Grocery stores bagged our groceries in brown paper bags, that we reused for numerous things, most memorable besides household garbage bags, was the use of brown paper bags as book covers for our schoolbooks. This was to ensure that public property, (the books provided for our use by the school) was not defaced by our scribblings. Then we were able to personalize our books on the brown paper bags.But too bad we didn't do the "green thing" back then.We walked up stairs, because we didn't have an escalator in every store and office building. We walked to the grocery store and didn't climb into a 300-horsepower machine every time we had to go two blocks.But she was right. We didn't have the "green thing" in our day.

Back then, we washed the baby's diapers because we didn't have the throwaway kind. We dried clothes on a line, not in an energy-gobbling machine burning up 220 volts -- wind and solar power really did dry our clothes back in our early days. Kids got hand-me-down clothes from their brothers or sisters, not always brand-new clothing.

But that young lady is right; we didn't have the "green thing" back in our day.

Back then, we had one TV, or radio, in the house -- not a TV in every room. And the TV had a small screen the size of a handkerchief (remember them?), not a screen the size of the state of Montana.

In the kitchen, we blended and stirred by hand because we didn't have electric machines to do everything for us. When we packaged a fragile item to send in the mail, we used wadded up old newspapers to cushion it, not Styrofoam or plastic bubble wrap. Back then, we didn't fire up an engine and burn gasoline just to cut the lawn. We used a push mower that ran on human power. We exercised by working so we didn't need to go to a health club to run on treadmills that operate on electricity.But she's right; we didn't have the "green thing" back then.We drank from a fountain when we were thirsty instead of using a cup or a plastic bottle every time we had a drink of water. We refilled writing pens with ink instead of buying a new pen, and we replaced the razor blades in a razor instead of throwing away the whole razor just because the blade got dull.But we didn't have the "green thing" back then.Back then, people took the streetcar or a bus and kids rode their bikes to school or walked instead of turning their moms into a 24-hour taxi service in the family's $45,000 SUV or van, which cost what a whole house did before the "green thing." We had one electrical outlet in a room, not an entire bank of sockets to power a dozen appliances. And we didn't need a computerized gadget to receive a signal beamed from satellites 23,000 miles out in space in order to find the nearest burger joint.But isn't it sad the current generation laments how wasteful we old folks were just because we didn't have the "green thing" back then?

Please forward this on to another selfish old person who needs a lesson in conservation from a smart young person...

We don't like being old in the first place, so it doesn't take much to **** us off...especially from a tattooed, multiple pierced know it all who can't make change without the cash register telling them how much.

 

Can I just get an amen on this one please... Just one amen 😎

 

1 Amen ...

I know it was Off topic and so were the other posts... now IF someone can post some other info on Kits I would like to see it too ... I only see them on Fleabay, Amazon, and on the Chinese websites anymore .. and the few others I mentioned.

 

First off brushes Rarely go bad in an Alternator.... you have an external Regulator so that in not something to go bad in the Alternator the only thing left is really Diodes or windings and on occasion bearings.
