So I just hooked up my hydro steering and was trying to bleed the system with the engine and belt off. Everything has been triple checked to make sure it's hooked up correctly. The ram is a psc 2.5x6 and the pump is a TG, the orbital is a charlynn. I filled the resevoir and started cycling the steering back and forth. Most of the air is bled out and I noticed it would start spinning the pump pulley while turning the steering wheel. When you hold the pully from spinning you cannot turn the steering wheel. Keep in mind there is no belt on the pump. I went as far as to try and start the truck with the belt on and when you touch the steering wheel it shakes violently back and fourth like it's going to fly off. We have not been able to cycle the ram at all. Any thoughts? Bad pump?
 
Believe it or not some of the valves depending on the manufacture have been timed wrong. Its a simple fix, I'll post up a link where I saw it.
It happened to me once, when we fired it up the wheel went back and forth out of control. I was dumb enough to grab the wheel....I don't recommend. It about broke my wrists.
This may not be your issue but its a start.
The lines swapped on the ram would just change the direction.
 
Thanks for the link. I have another orbital I can throw on it and see if that works. Everything is new except for the orbital on it now.
 
Either your lines are backwards or your orbital is 180 degrees out. Bottom of the orbital SHOULD have the ports labeled. P pressure R return a and b. Check it make sure you don't have pressure side hooked to ram. I'm a hydraulic specialist lmk what you find pm if you need a hand bud
 
Tried to re time the orbital using a thread on pirate. We aligned the pin with the dot on the star but I couldn't see any other way of making sure it was in time. Put it back together and it just does the same thing. Pretty much lost.
 
Was that the way it was? Like he mentioned it can be out of time. You can align it with the peak or the valley (on the star shaped cam), one way is correct, the other is wrong. On certain manufactures, the mark is incorrect, mine was. I took it apart, retimed, worked great. If you notice the slot on the opposite end of the shaft, the mark that's on the timing does not correlate, don't align with this mark.
 
Ahh so it's either a peak or a valley? I'll try it on a peak next and if it dosnt work I'll send it off to be worked on.
