Unrestored 66-67 Alternator

[Michael H.]

Does anyone happen to have an UNrestored 66 or 67 alternator. I'm trying to find out if these have the same black paint on the stator ribs, the exposed part between the alternator front and rear case halves.
We've already concluded that the 63-65 stator is painted black in this area instead of the previoiusly accepted carmel colored coating. Not 100% sure about 66-67 though, yet.
Pic below shows the semi gloss black paint on the stator of an unrestored 63 alternator.
Thanks.

Micheal; This is off of my 67, hard to tell if it had black paint or not but I think it did. Alt date is 7 D 18.

Re: Unrestored 66-67 Alternator

Thanks guys. That 1100750 sure shows a lot of original black. I think I'm more and more convinced that all 63-67 stators were black.
Still would like to see a few more examples.

Michael,

Here's a photo of two stators:



The one on the left is from my 67 37 amp alternator (7F16 unrestored). Note the black paint on the inside. On the outside rim, it is so warn, you really can't tell if it was painted.

The stator on the right is a donor from an replacement 60 amp alternator which is now in the case of my 37 amp original along with it's rotor.

Don't believe that picture of the 63 alternator is unrestored, it looks too good.

Thanks Jerry. I agree, it looks like the original stator had black on the center rib. (also looks like it worked pretty hard at one time. black windings)
The only area that would have been coated black is the rib and a small area on either side of it.

The alternator in the pic above (1st post) is the one on the low mileage unrestored Lance Miller 63 car. I have a feeling it may have been carefully cleaned but not disassembled or restored in any way.

Pretty sure Wayne Midkiff has a great picture of a new/NOS stator that clearly shows the narrow band of black.

Mike,
Are you sure it is black paint and not form of dye or black oxide? I ask that because in most cases the outside surface between the two cases is bare rusted steel from exposure.

My 65 that I restored years ago appeared as if nothing (some rust) was on the stator sheet metal laminations. But the wire windings were very carmel looking. It looked much as other guys have posted pictures of. Even the portion that fits tightly under the aluminum castings appeared bare steel. I would expect if it was paint to see traces of it. But nothing except aged steel with some rust.

I just restored a correct dated '66 alternator for my friends late convertible and it was a very faint carmel like color, but mostly rust. Once taken apart the portion of the laminations fitted with the aluminum castings looked much the same as my '65 did.

Also my very early '67 #440 had a faint carmel color that I also restored the same. It is also correct dated original that the previous owner of 30 plus years kept. The only problem with it was worn brushes, and full of crud, but I completely restored it.

Sorry I never took any pictures, but hope my restoration experiences helps. I do all my own work, and never send anything out.

Michael,

I just took a close look at my 67 stator in the garage stoarge box (the one in the picture).

Yes, it is painted black on the exposed rim as well as both of the unexposed sides where the paint was a little more protected.

The windings in my stator have a different black coating on them, looks almost like a gloss insulating paint.

Michael -- here's that shot you've seen before, plus 3 others that show that it was sprayed on; notice where the spray fans out at the case bolt slot. Almost no paint touched the vertical sides of the 3-lamination raised center .

One caveat; the part # 1959531 is for '63-5 C60 53 or 55-amp alternators (1100633, 663, 694) and may not apply to others '63-5 or to '66-up [but I doubt it'd be different].

I have a new 1959381 stator and it is painted exactly like your samples, i.e., a light band of semi gloss apprx 1/2 " wide around the perimeter.

Re: Unrestored 66-67 Alternator

For what it is worth, My 67 SB alternator, was an over the counter Delco in 1972 or 73( as I remember). It is a 1100570, 61A, 1D23, 12 neg it looks to be bare metal no coatings. My restored (by John Pirkle) original is a 1100750, 61A, 7A24, 12 neg. it has a yellowish coating. Dale

Thanks Wayne. That's the picture I was hoping would show up. As far as I'm concerned, your pic, Jerry's pic and others that I have are proof that these things were indeed coated with black and that process was used at least for 63-67.
I know that at some point in time, the black was no longer used on new stators but I don't know when. A guess would be 68 or 69??

That black coating wasn't very durable and that would explain why most don't show any signs of it. Also, as the years went by, most of these things have been "rebuilt" by companies that do huge quantities and the parts are not usually kept with the original case which would explain why many show only the carmel coated stator from some later unit. Also, I suppose their cleaning process would remove any trace of black.

Thanks Dale. I'm sure the black coating process was long gone by 1972. I don't know exactly when it was deleted though.

Re: Unrestored 66-67 Alternator

So, of all the people that visit this board, there are only three that have unrestored 66-67 alternators? Have all the rest been restored?

Re: Unrestored 66-67 Alternator

MH: I just went outside in my PJ's to find you one. It's from an early '67.

I think the problem (with lack of picts) is that most of them probably look bad, so why take the photo. Mine does not show any paint, but is rust colored. Since I have no conclusive evidence, I didn't yet take the photo.

I will clean up the area and see if I can find any black finish.

Thanks for the question.
