power steering pump pulley
Hey everyone,
I am trying to get a power steering pump pulley from march performance to match my set on the engine. Its a 79 vette, and if someone has this, could you give me the product number, or the other way i can figure it out is if someone has the oem number from the pulley on their vette. I think the pulley is the same from 74 to 82. I would use my own oem number, but for some reason or another i dont have one on my pulley.
Thanks for all your help,
Matt

I agree. Autozone has the tool and you can borrow it to pull the pulley. If they are close, call them and make sure they have it in store and not loaned out. Then take your pump and a couple of tools and head to Autozone and pull the pulley right there and give thier stuff back to them. That's what I did.

NEVER! Push or pull on the pulley while reacting directly on the pump housing. You must use the special tools that screw into the pump driveshaft and therefore react against it rather than the pump itself. If you try and react against the pump housing, you will break things inside the pump.
Also you need those special tools that only react against the pulley hub. If you push or pull using the outside edges of pulley, it will bend and distort the outside diameter.

thanks for the advice i have the puley puller, the problem im having is that i cant get the set screw out of the center of the pulley. I think it is frozen in there, and i have gotten a pipe wrecnch put on the center and had my dad with another pice of pipe put on the allen wrench that is used to take it out. We were putting at 150 ft lbs of torque on the damn thing and it didnt do anything, not even a budge. Also i really dont care how the pulley looks when its off since im replacing with a billet one, but would like to have the pump still working when all said and done 
Thanks again

There is no set screw in the center of the driveshaft! There is nothing for you to remove.
The 3/8 hex drive in the end is for the factory to test the pump before the pulley is installed. Behind the hex (deeper into the driveshaft) is a female 3/8-16 UNC thread. That thread is what the tool screws into.

jim is right , there is ..or atleast isn't supposed to be a screw on that shaft.. maybe a previous owner has screwed one in and couldn't get it out?

It sounds like we may all have some different pumps and pulleys on our vette. My pump did have a bolt on the end of it...mostly just to keep the threads clean for any future removal/installation cause that pulley was on there!
If you can't get the bolt off with 150ftlb of torque, then I think it's time to shop around for another pump.
