Well, add another part to my list of things needed...

Was taking the generator apart, and the nut holding on the pulley was frozen solid. No problem -- a little bit of penetrating oil then heat could persuade it.

Only problem is, ya have to hold the pulley still while turning. So I grabbed the only thing possible, one of the fins. Well dang if it didn't crack right as the nut loosened! <img src="http://www.aaca.org/ubbthreads/images/graemlins/mad.gif" alt="" /> So now I have to dig up another pulley somewhere.

Not it's fault, I should have seen it coming. But hey, good to be back in the trenches! <img src="http://www.aaca.org/ubbthreads/images/graemlins/tongue.gif" alt="" />

CBoz, Hint for the next time. Put a belt on the pulley and grab ahold of the belt close up to the pulley. This gives you some leverage to hold the pulley while you turn the nut. Sometimes vicegrips on the belt gives a better grip. Careful with the heat, you don't want to melt the windings.

I made sure to keep the heat localized to the nut itself, but that belt idea is a great one, Bill. I'm sure that it, combined with the heat and oil, would have done the trick. Oh well, maybe next time.

While we're on the subject, do you have any idea what tool to use to get the field coils off? If you look on the outside of the generator, you can see the two square notches for where the field coils attach. I first thought a 1/4 drive would do it, but the square is just slightly larger. Will head to Lowe's tomorrow to see if there's a 5/16(?) square socket that will fit it.

CBoz, I've seen pictures of a vice like tool that is used to remove the field coils from the body of generators and starters.Most of those coils have been in place since Henry put them on at the factory and those bolts have grown in place. Have a starter/generator rebuilder do the entire job. For the price it's not worth risking the gen.

Can you weld the fin back in place on the pulley?

Bill

The metal on the fins looks awfully weak. I could weld it back on, but then I'd have to worry about whether they were balanced correctly or not. As far as I can tell, it's a "78" part number, so the pulley was used on Fords as well -- it shouldn't be too rare.

I agree with you; if the field coils don't want to come out easily, I'm not going to mess with it.
