Default My alternator died.

I got a remanufactured one from Advance Auto Parts, but decided to take a picture of the old one before I turned it in for the $10 core charge:

That would be a big fat NO! Don't do it!!!

I'm going to have a hard time going to sleep tonight. That is something a 26 year old would do in 1976....ask me how I know.

Sorry to hear that. Yes, I remembered when I had my car checked out that was one of the parts the guy was taking a very close look at. Alternators with that part number are relatively rare, and it is also a date coded part. The date 0B3 would be February 3, 1970. My car's build date is March 23, 1970, so it was a "numbers matching" part.

I figure I'll just keep it in a box for the next owner.

Tear down and inspection of the internals is not complicated and parts are not expensive. The hardest thing to do is getting the nut off the front and that is easy with an impact gun. Might need help there. You need an electrical meter and some time. Check the diodes with the ohm meter, the brushes for wear, the bearings for wear, might be able to clean and regrease. Need a straightened paper clip to reassemble the brushes. You already have a picture of it as it sits so you will know how to clock it. DO IT!!

OP, go to Advance or other stores and get the rebuild kit (brushes, bearings). That's almost certainly all it will need.

Take it apart, then clean up the housing ('soft' bead blast works great - I used to rebuild a lot of these for show cars). Then, before putting it back together, put a few light coats of satin clear on the casted parts - it will keep them looking like new for a loooooong time.

I used to get the bolts cad plated too if they were a little scummy. You can do this no problem. I should put up a 'how to' post on this sometime............

PS: when you're done, the store you purchased the rebuild kit from will test your rebuilt alternator for you - at least they used to. The last one I did was about 10 years ago but I doubt any of this has changed. I've probably done 80-100 of these, and 100% of the time the rebuild kits worked like a charm.

PSPS: if you've already taken you original core back, get to the store and get it back before they send it out!

if you can r&r the old one you can rebuid it too

,leave the nut/pully on,just take apart the 4 side bolts,and pull the back off[with the outside mag/wiring ] attached,and you will replace the diode-trio,and brushs

rebuild kit is probably $40

youtube is your friend

Took my '79's original 38 year old alternator that was failing to a local shop Texas Alternator and Starter. They rebuilt it and cost me only about $100. Can't beat that.

Great stuff guys, thanks! But, I have a light fixture in my kitchen that is hanging by it's wires waiting for me to re-spackle around it (I replaced an incandescent with an LED fixture, and it didn't fit the old hole perfectly) for about 7 months now. In other words, I'm slow to get around to project stuff! I would love to rebuild the original and put it back in, but there are probably 20 things I want to do to the car first. Especially since I already replace the alternator.

FWIW: I replaced the alternator Wednesday night. All I have to do now is reconnect the battery and test it to get the car back on the road. I hope to get to that tomorrow. Will I?

If you havent already turned it in for the $10, put it on the shelf and sell it to someone who needs it. or eat the $10.

Do not toss, trade or sell the orig alternator. All the electrical parts from the new one will bolt right in the OE housings. The newer stuff is harder to work on. They did this to put the rebuilders out of business and make replacement the only real option. But this alternator is about the simplest to work on there ever was.
