rebuilding your alternator
« on: December 18, 2014, 04:03:27 PM »
Has anyone rebuilt your alternator to concours standards.  Mine is it good shape, but I want to clean up the case.  I dont know how I am going to put the Autolight stamp on it.

I was just wondering if anyone has done this?

It can be done . It is not cost efficient to do it one or two times with all that has to be done.  If you WANT to do it for your own experience that is a different story.

I just wanted to keep the original alternator with the car, it worked just fine when I took the car apart, really not much to them, I just dont know how I'm going to put the red Autolite stamp on it.  I was wondering if anyone has ever had a stamp made.

As you may know, you could send it to Jack at deadnutson.com.  You will get your own unit back if that is what you want.

Just out of curiosity, what is the yellowish coating on the outside of the coil. Is it really just a varnish?

Thanks!

Well sort of- it has a scientific name that I can't think of at the moment (someone will goggle and find it) but it's an insulating coating for the windings

Yes it's a varnish, but also an insulator and very quick drying adhesive that is used to keep each strand of wire in place for maximum voltage and current output. Special winding machines literally throw the wire into place on a form after it goes thru an industrial type alcohol activator. The wire is covered with the varnish from its factory, allowed to dry and wound on spools for use.

I found Mothers[tm] Aluminum Mag Wheel Polish will clean the alt case very well ;)

If you buy the stamp  - let me know, I would like to borrow it.

+1, it will be way too shiny if Mother's polish used.

Would a vibratory tumbler with ceramic media fit the bill ?

Don't believe so since aluminum is a soft metal. The challenge is getting it clean while getting a freshly cast look to the cast metal then adding the fresh machined surface to those areas.   Wish I had enough of the same aluminum parts all with the same well used finish that we could try different things on to find a decent process.

You would think so - but was not.
You simply wipe on and wipe off.
