1967 Alternator Stator Color exposed plates.... revisited

Re: 1967 Alternator Stator Color exposed plates.... revisited

Vote for black, my 64 was never rebuilt (owned since 67 and know past history) and still has the "I" dated diodes (oh you say no such letter was used - it was on mine) Last year I inspected a 69 that was black and has been in the cellar since 1970. In both cases there was not much left of the black, mostly that optional rust color. Agree it's not the caramel stuff used on the stator.

My NOS part is a dark brownish black & yes, it's for sale.

Rich,
I think you will find that the early cars 63 - early 66 were predominately black and early 66 - 68 were mostly the carmel coloring.

I'm pretty sure there is some outliners in the middle that are some of each. This is one of the restoration saturations that has gone unchallenged till as of late right here on this web site.

Looks like guys are finding just as I said back in #2 post response. The judging says both in a around about way also.

Yes Since Ken's is "kinda" aged Caramel by the sound of it, and others I've seen are black........Okay.....I decided on...............Black.

Here it is, finished it this morning. I still have to clean the Diodes and get them stamped properly. Doing that on Wednesday.

Richard,

Double check the alternator fan, it may be from a later model. I think the 64-67 fan may not have the space in the middle of each blade, lets see what others say.

The black looks very nice, please explain how you are stamping the diodes.

Tim, Yes I was not positive about the fan. Just yesterday I viewed some original 1967 parts including a alternator. Quite rough but the fan is clearly different. As you say there are no large spaces between the fins. Here's the reproduction, and obvious difference.

This one I have here.....

I ended up taking the alternator apart again yesterday morning because I didn't like the appearance of the edges of the stator that could be seen through the upper large ventilation holes at the rear case. I cleaned the stator edges on both sides and simply brushed on some black around both sides of the metal ring. This will also keep corrosion from forming in the future.

I also did a thorough cleaning of the armature in the restoration/rebuild process. This was a pain but necessary. There were many years of flaky carbon brush dirty areas on the inner surfaces between the metal plates and on the windings. I didn't want to use any type of spray solvent for fear of winding insulation damage. Many Q-Tips and acetone cleaned it up nice. I kept the acetone very clear of the windings and just dry brushed those.

I have access to a set of rubber stamps to do the diodes correctly. Tomorrow I'm visiting a friend and he's stamping them for me.

Re: 1967 Alternator Stator Color exposed plates.... revisited

Rich are you sure the stator winds are good. They look pretty black. Kinda like this stator got cooked...?

Answer to the diode printing is custom small stamps are available on line. You lay out what you want and the size in the "custom section". I ordered and used two sets for my cars. Takes a bit of trial and error to get good sharp results on those small diodes. Alternator rebuild is NOT rocket science and if you do it your self can be correct vs the incorrect services offered. Services offered are often incorrect surfaces on the castings and incorrect needle bearings. Be sure to have correct original stampings as these are also detectable.

Gene, It's actually black paint from some prior process, either Delco or a rebuilder I'm guessing. The insulation is in fine condition.

I tested the fields and all are within reasonable limits. No dead shorts and see a higher reading than a dead short. This alternator worked fine in the car before I restored it but I have a electric shop near me that tests my alternators and generators for me under load. When I get the correct fan and torque the pulley nut I'm bringing it there for test.

[QUOTE=Joe Lucia (12484)There are many formulations of Glyptal and each had a unique color.[/QUOTE]
Never knew that Glyptal came in more than one color. Interesting information.

Re: 1967 Alternator Stator Color exposed plates.... revisited

In case there is interest - I've done a few of the alternators now. I found reasonably priced units that needed to be rebuilt to get date correct for my 66 and 67, and a friend's 66.

Pictured below are the cases together that show the caramel color and the stuff I used to coat the stator, and the stamped diodes. I order the stamps from an online place and they look pretty much like an alternator that a friend had rebuild from a well know rebuilder.

Don and Rich, very nice. It is good to see guys restoring the components rather than "sending it out". After all this is a restoration club. Nice work.
