Thanks Dan ..

Sorry for those all threads .. :frown:

I now the " problem " never will be complete solved, also know that's like a auto locker .. you need to learn how to drive it ..

thought from now I will be driving more carefully at the turns .. but still thinking ( based on friends experience with a F350 and PSC hi flow pump ) that my setup can be go better ..

Did you ( or someone else ) now if those wrangler pumps have a valve to " port " .?
 
You are not going to ever get a hydraulic ram assisted steering system to turn the wheels from lock to lock at idle as fast as you could before you introduced the hydraulic ram into the equation.



:meh:
 
one question for all that have the ram assist in your Cruisers ..

Can you drive it as DD with this steering speed .? ( pulling out all other misc stuff like tires, gearing etc .. )
 
I could DD with no problems.

2F with all the emmssion items, H42, Rock Box, Orion 3:1, 4:11's on 35's / AGR pump, gear and cylinder with no problems at all. The only time I have had problems is when I drive my rig to the trail and get caught up in slow traffic on a tight trail.

I do it frequently....



2F/420/4.3Atlas/4.88s/42"Swampers/PSC pump, gear and cylinder.


Works great, but again, it does not steer as fast as it did before the steering cylinder was installed.

The benefits of the ram assist more than out weight the supposed detraction of the slower steering at low engine rpms.
 
it means when you do a tight turn on the street, ( said to the right ) on to the traffic .. after yo are in the way you can turn yout steering back to the center without problems ?

The issue that drive me nuts it's this .. I was on second street, heading to the main .. was on heavy traffic to I need to " jump " on the main street when I got the chance .. but after I do I need ( as usually .. things that you really never think about ) to re - align the steering to go straight ..

But surprise .. ! I can't ( as fast as I shlould ) so I hit the sidewalk a bit and then my PS finally do the job and fill the piston and I was able to aling my steering straight ...

If I drive slow it's was not be a problem .. coz allow the PS pump to slow fill the ram ..

Edit: sorry .. I hope my english allow me to express the situation ..

When you are lane jumping, are you idling or standing on the fuel pedal? RPM's make the pump turn faster and steer quicker.

I doubt you are lane jumping at idle.

My previous post tale was from total stop to jump in the traffic line .. was raising the rpm but usually Tencha idles at 600 - 650 rpm .. and yes when I'm driving at 1.5k rpm the steering react much better ..

I usually make my shift around 1500 rpm .. ir requires something special 2000 rpm ..

I will take a vid tomorrow I hope it can show how slow or fast my steering performs now ..
 
Here is the vid .. it don't looks that bad in the video .. but I would follow the WTOR instructions to see if I can improove it . since I'm not getting much help from PSC ..

You are one Crazy Guy for filming in that trafice while driving.

My theory.

When sitting, your hydraulic ram is pushing the tires sideways. The contact patch of the tire to the ground will determine how much pressure is applied. It will be harder to steer when parked. When you drive, the tires are rolling. It is easier to move the contact patch side to side when the tire is rolling.

I think rams have more power when extending than compressing but I may be wrong. When you turn the wheel and the ram extends, the steering wheel is light in your hand. When you turn the wheel and the ram is collapsing, the steering wheel is heavier in your hand because it does not have as much pressure.

Just my theory.

wasend my wise idea .. and actually it don't show the issue at all .. :frown:

As you see it's easy to me turn ( slow ) side to side with no problems ..

Actually it's plus more rpm on the engine and the pump .. it's just about the speed that you need to move it as you do when you are driving ..

( was the usual speed that you use with you aren't hydro assist )

I'm totally lost right now .. just will try to port the valve and see what it can do ... hope better than worse ..
 
Wait for Poser or Mace to watch the Video and give you advice on what direction to go.

My experience comes from the 1 (one, uno) AGR system I put on my truck and what I learned along the way. My Hydraulic experience comes from building and working on Log Splitters and working on tractors. I am by no means an expert. If I knew 100x's more about hydraulic than I do now, I might be considered a novice.

I will call PSC again for you and send them a link to you You Tube Video.
 
I've been reading ( uff .. ! ) in the web coz a friend yesterday told me, if where a problem of fluid flow in my stup, the cavitation would be present at the system and reservoir ..

So I was reading about cavitation ...

What is cavitation?

Cavitation occurs when the volume of fluid demanded by any part of a hydraulic circuit exceeds the volume of fluid being supplied.

This causes the absolute pressure in that part of the circuit to fall below the vapor pressure of the hydraulic fluid. This results in the formation of vapor bubbles within the fluid, which implode when compresed.

I didn't see any cavitation signs in my reservoir after an hour or so driving around the city .. so I'm still lost..

Dan .. appreciate your help with PSC but maybe they are too busy and I'm not representing a rentable business .. so they have other customer with more easy dolars to earn ..
 
Another interesting info about ..

The second noise is caused by cavitation. As you increase pump speed, more and more fluid is forced through the ports per unit time. There comes a velocity where the fluid just doesn't want to move that fast, and the vanes inside the pump will cause a vacuum, which is instantly filled with oil vapor. When the vane reaches the high pressure port, this vacuum cell is opened into a high pressure cell, and oil rushes to fill the void.
 
Info from PSC ( thought I'm gonna relocate my PS cooler )

Finally, for those running a remote reservoir or power-steering cooler, PSC recommends running no more than 16 inches of 5/8-inch diameter hose to prevent cavitation problems caused when the pump starves for fluid. Make sure your remote reservoir is the highest component in your system. If you're running a power-steering cooler, make sure to mount the cooler lower than the fluid reservoir and that the input to the cooler is on the bottom and the outlet is on the top. That way the fluid can't cascade down when the engine is shut off and cause an air pocket.

So are they going to modify yours or are you just buying one from them?

this one looks like wrangler pump but by Kelvin aren't the same at all .. and about modifiying mine .. it will cost much more just send mine to 'em than just buy this one ..

Anycase I'm still waiting for measurements and info from he before I place the order ..

At the end he said this wil do the job with a smaller pulle just like the one that I'm running right now ..

I still have in mind try to modify mine and let's see if that didn't function will buy this one .. ( never end road :D )

You did not spare any expense on Tencha building it up after the roof came off. Don't mess with a vital component of the vehicle like steering or brakes when it come to what you need.
