I am looking for information on how an original 67 Hemi alternator looked. Did they get the paint daubs on the back. If so what color and where. Was the part of the stator that can be seen between the 2 case half's finished in a reddish brown transparent insulating coating? Anyone have a good picture of a original?

Thanks
Dan

I'll work on getting the correct part #. I have never seen the amperage color swabs on anything earlier than '70. The sole exception being a special "isolated field" alternator used in some higher amperage applications in 69. Strange looking piece. What we do typically find on the back shell near the top threaded hole is a black or red dot. Usually about the size of a pencil eraser. The NOS and low mileage originals appear to have a thick coating of tinted insulating varnish on the stator frame. Sort of a translucent walnut color which quickly rusts underneath. Rotors are finished in the same type insulating varnish. I'm not very picture savy but maybe another member here can post up something.

Thanks, I have some pictures coming of an original unit. I was told it has a dark red paint mark about 3/4 long and about 3/16-1/4 wide. Would like any information I can find from the original units to try and get these right.
BTW, I have a 69 unit I was looking at that has a dark red/maroon paint marking on the rear. If it would help you in any way I can send you some pictures.

These are some pics an NOS 67 alternator I have, it's supposed to be for a Hemi. The band in the center is lighter than most I have seen, more of a honey gold color than the darker brownish color.

FWIW I have a used original 67 casting case that is marked identically to the above NOS example, most of the paint markings are worn away but there is enough still there to see what it is. All original stators I've seen (the exposed metal band) were bare steel coated in the insulating varnish and accordingly have a honey colored finish, some darker than others but it's all the same stuff.

MANY 69 and earlier alternators I've seen have been restored with incorrect paint markings, the pre 1970 cases definately need more scrutiny.

I thought 67 alternators got the single v-belt pulley?

Thanks for the pic's!

Is this pulley Hemi only?

Yes they should.

*BTW, I have another 67 case that has the greenish paint mark, no pink paint mark, but has a red felt marker slash across the large mounting ear hole. Personally i wouldn't add any markings until it's been confirmed as to exactly what is correct for your application.

From the 67 parts book, no. After a lot of researching, I went with a single pulley on my engine.

Does the 67 parts book show what the dual pulley would be on? I don't have a 67 book.

Scott, how would I really ever find that out? Unless I had the original unit from my car, I'm stuck going with the norm. Should I just refinish the stator ring to look correct and stop worrying about it

Thanks
Dan.

My thoughts in general on inspection marks, paint daubs, etc. are that if you don't find them, you don't add them.

IF it's ever proven that "all 67 Hemi's got a green paint daub" then fine, easy to add one, IMO it's more correct without it unless you have proof that it belongs there. I am constantly on the hunt for new information as are others in the hobby, the more original and NOS examples we discover and study, the clearer the overall picture becomes. At this point we are still at the beginning of the learning curve on pre 1970 alternators concerning the finer details, alternator details have been ignored for a long time, only recently are they really getting thier day in the sun. So yes, go ahead and get it done in every other known detail, just skip the paint markings for now.

Dave Wise(MMC Detroit)and I have been working on "beefing-up" the alternator section in his new Dodge judging manual. Like Scott said above the pre 70 cases are uniquely marked and varied. For example, we see at least three different case bolt head types. Clear zinc w/no pattern like the type on the hemi unit above, clear zink with a "bullseye" pattern - more common on 70-71s, and black phosphate coated with AF stamped indented head. The only consistent marking Dixie has noted on the production line rear shells is a small black ink? mark again as seen on the NOS unit above. Ocasionally, we find some random red ink? locatd on or near the rear pivot eye. We have also noted red paint on a couple of the 37 amp rotor stems. This can be seen looking through the pulley throat. Again, agreeing with Scott, we only replace the paint/ink marks on a customer's alternator if we have found evidence that it was there before cleaning.
