http://www.stu-offroad.com/steering/pspump/pspulley-2.htm MY SETUP IS JUST LIKE THIS I rented a PS pulley puller/ installer from AutoZone's loan-a-tool. I'm trying to swap a double pulley onto a pump. I got the old pump off no worries. Now when I went to put the new pump on, it wasn't really threading into the shaft right. I think I've stripped the bottom 2 threads on autozone's tool. I guess the inside of the shaft doesn't have threads, I need to go het a light and look. Or maybe I didn't threads the installer deep enough.. whatever be the case, the pulley is not pressed on, and I think the tool is unacceptable (I'll try to throw some black paint on it, and maybe grind the bottom 2 threads off). Oh yeah, I got and tried to beat the pulley on with a board, I don't guess that destroyed anything internally did it???? SO HOW IN THE HECK HAVE YALL INSTALLED PULLIES ONTO YOUR CHEVYS' POWER STEERING PUMPS? I'm begging for help, James EDIT: upon closer instpection, I'm pretty sure that the chevy pump is fine thread and the tool is course thread.. Does that sound right?now I need to find a fine thread bolt/nut/washer to install it.
