Power steering problem!

OK guys, I'm not quite sure what I did, but here goes. I have a 67 El Camino 350SBC with stock power steering. At this point everything with the power steering worked great. I decided to change the power steering reservoir from a black to a chrome one. I took the power steering pump/reservoir off, while I was re-installing the chrome unit, I had the power steering pump lying on the bench with the shaft supporting the pump. I was using a rubber mallet to install the chrome reservoir I noticed the shaft/bearing caved in about a 1/4 inch, (oh no). I wasn't sure if I ruined anything, so I re-installed it on the car. I might add, I also put on new power steering hoses at this time.

Here is where the trouble began. I started the car and I had to really crank down so the belt to get it really tight, so it would stop squealing. There was no power steering on the car. After about 5 minutes with the car running, the power steering pump got really hot, so hot the fluid melted the cap/dip stick. I could not get the fluid to circulate.

So I bought a new,(rebuilt) power steering pump and installed it. Well, the exact same thing happened as described above. I could not get the fluid to circulate, the pump housing started to get hot, so I shut the car off.

Could there be damage to the steering box, from the really hot fluid? I never had these problems before I changed the power steering pump. What did I do? Any help or suggestions would be appreciated....

I took the two hoses off the steering gear box and and there was no fluid at the fittings. I checked the hoses and they are not clogged. I don't understand why the pump is not pushing fluid through the gear box. What am I missing?

When you pulled the fitting from the back of the pump for the pressure hose.Did the valve fall out? did the spring fall out?
Did you reinstall them spring first, then valve? Also did you make sure the o ring on the fitting was on the second step off the fitting? If you changed it and didnt get it on the second step, and it is on the first step, it will be blocking the port in the fitting resulting in no assist.
Just a few things to check.
Never hammer or press a pump shaft. There are pullers and installers that work on steering pump pulleys.

Thanks for your input. Yes, I installed the valve correctly. The o ring was installed on the second step of the valve, keeping the small port un-blocked. This is turning into a mystery.

how did you install the pulley on the pump? Did you use the correct installer tool or did you press on the shaft ?

Update. I still cannot get the power steering to work. I am now on the third rebuilt P S pump from Napa auto parts in one week. (I am not there favorite customer), the pump is new, the hoses and fluid are new. I jack up the car and turn the wheel lock to lock 15-20 times. I check the fluid, I can see it circulating, but the fluid is frothy and full of bubbles.

The P S pump makes a funny noise when I bleed the system. I lower the car and there is no power assist what so ever. It seems that the fluid is not circulating in the gear box. Before all this started the gear box worked flawlessly. I take the fittings off at the gear box and I cannot see any fluid. I have concluded that I need a new gear box or I have the mother of all air bubbles and cannot bleed the system properly. OK guys please chime in, I need some help figuring it out...
