I believe it's not threaded. If it's like mine you pull the pulley with a special puller and then you use a different tool in the same puller kit and you pull it back on by using the threads inside the end of the shaft. It is difficult to do even with the specific puller, but that is the best way.
well then how do i get it off the truck its got a big alum mount that surrounds the pump and the bolts that hold the pump are behind the pully i really need to get this off

Locate the tool. You might be able to rent it. You may have to buy it. Where do you live? It is a two function tool. First it locks around the groove on the extended center portion of the pulley and then pushes on the end of the pump shaft to pull the pulley off the shaft. It is best to remove the shroud first so you have enough room to work on the pulley. Then you take off the pump and reseal it. You can get the whole reseal kit or the front shaft kit or the reservoir O-ring. Reseal and then put the pump back on and there is a different set-up in the puller kit which then screws into the threads on the end of the pump shaft and pulls the pulley back onto the shaft. Be careful of these threads. clean them out good before you use them and when you're done leave a little white lithium or regular grease in there to protect them and keep them from rusting. If you can't find the tool, find a good Ford mechanic and talk to him. The whole job can be done in an hour start to finish. You might be able to convince him to do it for $50 cash, you supply the parts.
I am having a similar problem, but my pump has a allen wrench hole in the front of the shaft instead of threads. I replaced the bracket and pump from another truck and the pully needs to come out about a 16th of an inch so I dont eat another belt.
If there is an allen wrench design in the end of your shaft then it must be there to be able to hold the shaft still while you screw and unscrew the pulley. I am not sure. I am guessing, but if it is a press stall and uninstall you definitely need threads. Believe it or not, engineers design and build all this stuff with much thought and specialty design concept involved. If it is an unscrew situation, you can tell which way it unscrews because it will unscrew the opposite way that it spins when the belt is on and the truck is running. This is set up so that it will self-tighten when it is running and working.

This is along the lines of what I was thinking, Im just wondering what I am going to turn the pulley with? I dont know if a strap wrench will measure up.
