Alternator Pulley

[Barry B]

I need a new pulley for the Motorcraft 12 V externally regulated alternator that I am putting on my 9N. The shaft is 5/8" in diamater and the pulley that is on it is for a much narrower belt than what is used on the tractor. I basicly need a couple answers:
1 What size pulley do I need, V Cross section and diamater?
2 Where can I to buy it?

Thanks in advance for the Info.

The correct pulley is #98NAA5825,,, 5/8" V and just a tad less than 2 1/2" O.D.

I just sold the only one I had in stock,,, Check here fer one and if thay don't have it i spec justs8ns does,,, this pulley is not cheap but is the only one I know of thats correct and werks.
Link to a discussion a week are so back

Hobo, Many thanks!

Couldn't find it here so i ordered one from Just 8N's, My alternator has a double 3/8" V pulley on it now so hopefully the thickness of the new one won't be a problem. I'll let you know how everything works out.

Hobo, I finally figured out that I had an odd fan on my NAPA rebuild. It had a bulge in the front. I found an Alt. rebuild guy who sold me a FLAT fan and the right spacers. He said he'd not seen one like mine had. For less than $10, I am on my way! Thanks again.
