new power steering pump questions

alright i just installed my new power steering pump and hoses. Filled with atf..... The paperwork with the pump told me to jack up the front and turn the wheel lock to lock 20 times to bleed the system. I did that then took it out for a drive. It's not smooth any more, when i make a turn i can feel the engine idle through the steering wheel. So, i attempted the 20 lock to locks again... drove it.. same crap. I also noticed the steering wheel doesn't retuurn anymore. I had the engine running and i was looking at the pump from the driver side and it looks as though the pump pulley is not exactly in line with the crank pulley. The area of the pump pulley closest to the fender looks like it is pulled in towards the headers, i put a spacer in there to push it out and it's still off.... i can't kick that side out any more because then it starts rubbing on the alt + fan belt. I double checked the tightness of the pump pulley and it's all good. Can i put any spacers in between the mounting brackets to kick it out, are there supposed to be any spacers there.....???? To the best of my knowledge i put everything on the new pump that came from the old pump, but i could have made a mistake... this is a 71 camino, the pump has the little key thing for the pulley and is not pressed on.

while searching through google i stumbled across this site... ihttp://www.tandmautomotive.com/1/info/steering_fluid.html it's interesting but i hear so many stories of people using ATF and how it just works great, plus my company bought 7 champion buses and they come from the factory with ATF as the power steering fluid... hmmmm.....

Sounds like you got a bad pump. It can only be ascertained with a pressure gauge but you might want to try another pump.

As for the alignment of the pump, GM uses a very complicated mounting system for some reason on their FEAD's. I know my son-in-law's 86 305 IROC is a pain. There are many brackets and spacers. One left off will throw out the alignment. You might want to try and find an illustration of the assembly in a shop manual or parts explosion to see if you have it mounted correctly.

As for fluid, the manufacturer)s) are very specific as to which type to use, whether TYPE F or DEXRON because of the friction modifiers used. Check a lubrication manual to see what your system requires.

As for the bleeding operation, when it states stop to stop, do not turn the wheel fully against the stop as this agitates the fluid. Sometimes you may have to let the car sit for awhile and check the reservoir to see if the fluid is aerated. If so, there is a special procedure to draw the air out.
