Hey whats up guys. So I have pulled my power steering pump but the pulley shaft is solid. I know the pulley shaft that has a large threaded hole is whats used to draw the pulley during reassembly. How is the pulley reinstalled with the Mopar solid shaft? Here is the shots of my old and new units.

Does that shaft have a key way? If so, the pulling slide right on and then tighten the nut.
 
No key way. Here is a better shot. Both shafts look similar (old and new).

Well then, your gonna need a nut to pull it down on the shaft. You could use an air gun to zing it on while holding the pulley.
 
I think Autozone has a loan-a-tool that will press off the pulley and help you press it back onto the new pump. BE CAREFULL WITH THE PULLEY & don't pull on it at all around the outside (only near the center hub) or it will bend...those pulleys cost about $100 (ask me how I know)
 
I used a press for my 64 pump
Well the issue is that the back plate of the pump and bearings can not withstand the pressing. How did you press it on set up wise?

Thank yes I will use that to get the pulley off but without an internaly threaded shaft I don’t have a place to grip it.

It's been a couple years, but if I remember correctly, the tool grips around the "almost looks like a wrench would fit on it" part of the pulley (really the groove right behind it) & uses a "jack screw" which pushes on the center/threaded stud.
 
I think you should have a keyway on that parallel shaft.
Mine had a key and the pulley slid on. The pulley has flats 7/8 inch to allow you to hold the pulley and torque the retaining nut.
 
Yup steve340

Ok hope this helps the next guy. So I was able to put the pulley on. It eas keyed but required some significant hand pressure to start it. I needed to expose some threads first to start the nut to draw it in. Not easy because you don’t want to damage those bearings. I had to walk/rock it on by hand to get it to move down the shaft.

Well done you must be a careful and patient person. Mine came with the woodruff key in the little parts kit. I fitted the key and a small burr came up. Eased that with a needle file and the pulley slipped right on. It was job finished in 10 minutes.
I have had a closer look at your picture and the little half round grey area is were the key should be I believe.
 
Yeah I realized after I started mating up the pulley and armature that I should have pulled the key then slip the pulley on and tapped the key back in. But it worked out ok?
 
Yes never removed the key. I pressed it in with the key in.
