I just ordered a replacement/remanufactured alternator for my 73 corvette. Now the salesperson said it would look almost exactly the same as my old when. The problem is, is that on my old one it had a fan with three blades on it, but on this one it has a turbine style fan that looks like a big circle with air grooves on the sides. Can't I get a correct fan for this thing so it at least seems to be correct.

What about having the original one rebuilt?

Take the fan blade off and hope you can swap it out? :eek:

Michael,

You should be able to take the new and old alt. to any competent auto part store and they should be able switch over the fan. Auto Zone did it for me on another car. They use an electric impact wrence to undo the nut.

Are the threads holding the nut for the pulley reversed, that is, do you
loosen the nut by turning it clockwise?

I wanted to keep mine original so what i did was go to my local auto store and paid $22 dollars for a rebuilt. Took it apart and put all the guts in my original. WOrks great.

Threads are standard. Lefty loosen, righty tighten. They are not reversed threads. That stud bolt can be very difficult to remove. Use and impact wrench.

Several years ago I did the same thing. I paid about the same amount and
got a 55 Amp. Put the "guts" in my original 42 amp. Now with the 4 halogen
headlights on it's able to keep up. (Still have the original 42 amp guts in a box)

The end of my Alt. shaft is an allen socket. Just put an allen wrench in your vise (pointing upward), and place the alt. on it. Then take a wrench
and loosen the nut. Done it many times.
