Hi, I own a 1993 ford thunderbird with a 5.0L HO V8. I"m trying to put the power steering pump pulley on and I have the tools needed to do it. The Instructions are a little confusing to me and I wanted to know if you could possibly help me out. Thank You."

Are you using a threaded shaft and nut that screws into the pump's shaft?

Yes I am, everytime I try to get the pully on, the threads dont stay and it comes right back off. I'm praying the threads are not striped. I was told to use a hammer but I know that can just make the pump its self prone to getting damaged. I guess what I'm trying to get at is there a nut and bolt that stay on the pulley once its on and if you have to buy a special screw and square spacer I need to buy to get it on properly? Thanks for replying

There is a tool kit that you might be able to borrow from an auto parts store that rents or borrows tool. It includes a bearing assembly to reduce the force on the pulling screw.

New pumps and new pulleys usually come with just a screw and nut but they are the correct thread. You're right about not hammering on the pulley as that will damage the pump, but what they were probably referring to was hammering on the bolt. Use the nut to put pressure on the pulley, then tap the bolt lightly to increase the force. Keep tightening the nut as the pulley starts to walk onto the shaft. Even with the special tool, it takes a lot of force to get the pulley onto the shaft so I still tap the pulling bolt. I've had the threaded tool extensions break numerous times if I just relied on the bolt pressure without tapping on it.

In case you aren't aware already, it is critical that the pulley be installed the exact same distance it was before to prevent belt squeal. Chrysler parts come with the appropriate spacer to set the position but they don't fit with some tools. If you're reusing the old pulley, look in the center hole for rust buildup. It will be shiny where the shaft was so you can use that as a witness mark. Install the used pulley just until the end of the shaft touches the beginning of the rusted area.
