I just had a CPP power steering system installed on my 64 D100 Town Wagon. I used all CPP parts, box, pump, hoses and brackets. All the parts seem to fit OK and with no leaks, the belt is tight and there is no visible air in the fluid. When the front wheels are off the ground it steers with just one figure. The problem is when the wheels are on the ground the steering is erratic, it will stick, then break free causing the steering wheel spin hard.
Any suggestions would be great.
Thanks
Mike

Re: One More CPP Steering Problem
I have the CPP on my 64. You say had installed? Take it back. My first guess would have been air in the system. Lift the front wheels again so pressure is on the suspension. You might have done it that way but, just saying. Move it from full lock to full lock 10-15 times. Look in the pump and make sure it is flowing good. Also, there might be a joint ungreased or too tight causing binding. Check the steering box through and on the outside of the frame that it isn't rubbing. The pitman arm can be close with that setup and rubbing on the frame. That's all I have.

Re: One More CPP Steering Problem
Any noticeable change in engine RPM or the sound from the steering pump when it sticks/breaks free? Is it better if you steer very slowly vs. trying to turn the wheel quickly? It could be that your pump is not keeping up with the flow demand. About 1/4 down the page on this link it discusses a similar issue (http://www.gmtruckcentral.com/articles/ ... eringmods/). Look at "Low Idle Flow Modification" and possibly discuss this with the installer and/or pump supplier. I opened mine up as described in the article because I found that when I turned the wheel slowly my steering worked fine, but turning it abruptly would cause a temporary loss of power assist.
Re: One More CPP Steering Problem
Well the problem with steering sticking then suddenly breaking free has been resolved. I called CPP and they thought it was most likely due to the steering box input shaft binding. After loosening the steering column mount at the firewall and realigning the steering column to the steering box input shaft, I took it on a 60 mile shakedown ride and it all works great, smooth lock to lock and I can turn it with one finger.
Thanks to those that provided suggestions.

Re: One More CPP Steering Problem
Curious if any of you who have made the change over to the CPP box have noticed any "slop" or "play" in the steering? I have everything new in my steering system from the tires up to and including the rag joint/coupler and still have what seems like excess play in the system. Honestly, the only assembly I've not touched is the steering column. I've made an adjustment on the steering box adjuster screw and that helped but did not eliminate the issue. I was expecting a lot better than what I have. Any tips or suggestions f rom those of you who have made this swap would be appreciated.
Thanks,

What size tires are you using? I don't have any suggestions.Series1Utiline wrote: ↑Fri May 15, 2020 2:46 pmCurious if any of you who have made the change over to the CPP box have noticed any "slop" or "play" in the steering?

Re: One More CPP Steering Problem
235-50-15s on a 7" wheel. Nothing crazy. Yes, this is an odd one to me. I'm going to mess around with a steering stabilizer to see what that might gain me in terms of a way to manage the remaining slop.
