It takes a special puller. The regular jaw type puller doesn't work.
The correct puller grabs the groove machined into the center hub.
EDIT:
The shaft depends on the press fit between the shaft and pulley to keep the pulley in place. There is no other set screw, bolt or anything that keeps the pulley in place.
To reinstall, place pulley on the shaft and place 2 or 3 flat washers over the shaft. Take a bolt that will thread into the end of the shaft, not 100% sure but I "think" it's 3/8"-16NC. Screw a nut onto the bolt and then screw the bolt into the shaft. Hold the bolt from turning with one wrench and tighten doen the nut with the other bolt untill the pulley hub is flush with the shaft. Unscrew bolt and remove washers.
NOTE: Be sure to install the pulley with front of the pulley facing out....I've seen 'em istalled backwards before, then there's no way to remove them.

Mustangs, Etc., Van Nuys, CA has 6 (818)787-7643
There are several more out there if you need more names.
One thing that puzzles me. When I installed factory A/C on my own '73 w/a 360 the power steering pulley was different. The parts catalog only lists one pulley and says nothing about w/ or w/o A/C.
Look at your old pulley, there should be an ID number stamped on it. According to the catalog it should be #7AA. If it's a different number let me know and I'll see if I can cross it over.
Not really super clear but in the first picture was the non-a/c pulley. It "dishes" out. The second pic is the A/C equiped pulley. The offset "dishes" in. Which one does yours look like?

Mine is the first pulley, I picked up a pump from the yard which was an a/c equipped vehicle, and pulleys dont line up, I was able to bend the pulley back, I closed the gap where the vbelt rides in, after I remove the pulley will check further to see how it "rides". I will let you know if I need your pulley, please let me know what you are asking for it, shipping to 93637

Jeff, I don't have that pulley anymore. I did the conversion a couple of years ago. Look at my previous post, if you do need a pulley check for #7AA stamped on the pulley. If that number is stamped on the pulley, any of the suppliers I listed have it (13 between the three that I listed). If that's not the number stamped on your pulley, post the number and I'll see if I can cross it over and locate one for you.

C7AZ-3A733-A .. Single Sheave P/S Pulley-stamped #7AA / 5 1/4" O.D. / Obsolete
Applications: 1968/76 F100/350 360/390 ~ With/without A/C makes no difference / Misc: 1967/80 Ford/Merc Passenger Cars.
Mike, if your P/S pump (steel reservoir) didn't have this pulley, a PO either changed the pump or the pulley, probably came from a car.

got the pulleys swapped from one unit to the other, rented a puller from autozone worked like a champ. was able to pursuade my original pulley with a hammer and a 3/8 drive extension to correct vbelt alignment
my pulley was stamped with 6AA, the other unit from the ac truck
was marked BOAR - BI, no 6 or 7 AA. got it back together and running, pulley looks good, going to run it and see how it does.
Thanks again for the input and feed back

FYI, my psp also has the Allen bolt that won't break loose on the pulley. That's what brought me here.(maybe original and most are just missing this cause it isn't needed) I'm about to look for a new pulley and turn the old one in with the core.

There is only a press fit that retains the pulley. There is no drive key either, it is a smooth shaft.
To remove the pulley you have to use a tool like the one pictured in post #2. You screw a bolt into the center of the shaft. Use that tool to clamp around the groove that's machined into the pulley hub, then screw the forcing screw down. This will push against the bolt in the shaft (you use a bolt so the forcing screw won't damage the threads of the bolt hole). As you tighten, the pulley will come off.
To install, get a long bolt, some flat washers and a nut. Screw the nut on to the bolt as far as it will go, then the flat washers and the pulley. Screw the bolt into the shaft. Align the pulley with the shaft and tighten the nut. As you tighten, it will force the pulley onto the shaft. Tighten until the pump shaft is flush with the outside hub of the pulley.
BTW welcome to FTE, lots of good people here.
