So a local fellow asked me if he could do hydro assist with no lift (42" no lift) on his K30. I'm not sure so I thought I'd ask here. From what I understand crossover steering wouldn't work without lift, so not sure if hydro-assist is possible with the stock setup?
 
If you mount it in front of the axle i dont see how it wouldnt work... But then again i have neither so its a moot point...
 
Hydro assist and stock push pull steering do not work together. You must run crossover with assist. He may be better off going full hydro
 
It will not work. When flexed the steering geometry changes way to much and puts a bind on everything. With crossover the steering moves in relation with the suspension and causes no bind.

Yeah, I remember seeing that now that you guys mention it. Also I think PSC has hydro assist kits listed on their website for both crossover steering and regular steering. Thanks guys.

That doesn't make sense to me. Now I understand that push-pull steering has more variation with axle movement than crossover does, but the fluid is going to fill the gear and the ram at whatever rate they take it. What balances this fluid flow is the mechanical steering linkage, just the same as with crossover.

If the wheels are turned as a tire drops into a hole, the change in distance between the pitman arm and steering arm will tend to steer the wheels. As the wheels turn, the tierod pushes the ram and fluid puts pressure on the piston inside the gear. This pressure tends to turn the steering wheel, but if you resist it, your torque will drive fluid back in the other direction. This may put more stress on the drag link and pitman arm than with crossover steering, but this doesn't mean that it's any harder on them than non-ram steering would be.

The bottom line is you get the same disadvantages of push-pull steering, but with added steering power from the ram assist.

Now if you put an orbital valve in and kept the stock steering linkage, then that WOULD be a binding disaster. But ram-assist works based on your input torque to the steering wheel, whereas orbital valves work based on the position of the steering wheel.
 
I have a pto winch on the front, and the pto shaft would get in the way of the crossover drag link. Now I"m thinking conventional hydro assist might be an option for me also.
 
I am trying to run my pto winch around my crossover steering now. Looks like it is going to be fun.
