Trying to troubleshoot some full hydro issues. This is not my truck, nor my setup so it's getting a little confusing :grinpimp:

Steering feels like manual steering with the Jeep off, goes from lock to lock with no issues. When the Jeep on it is only VERY slighty better, still feels like manual steering. Truck is running 37" tires.

Pump doesn't whine or anything when bled, and I have tried two identical pumps of unknown state or origin. Fluid level raises and drops with the ram.

Running this pump

I have removed the shims and drilled the hole to 5/32" to get some more flow. Did not seem to change.

Uses a Char Lynn orbital valve with who know what specs... ports are labeled "In, Out, F, R"

Lines go from pressue to "In"
From "Out" to resevior
From F to right side of ram (I think)
From R to left side of ram (I think)

Ram has a 1" rod, and the OD is 3", unsure of the ID or stroke.

Any idea what I should be looking for? Bad pump? Bad orbital?

Any way to check???

Thanks! :D

double ended ram? Fluid should not rise on a double ended. and make sure your junk is setup like this:

That is what I am thinking right now... It seems like the only logical problem...

double ended ram?
Nope, single. Lines are routed right, they are all the same size (which I know is an issue) but I'm getting almost no assist from the orbital to the ram.

CharLynn valve should either be labeled L, R, P, T, or In, Out, L, R... there shouldn't be an "F" on there anywhere.

Did you check the hole in the side of the output fitting after drilling it? I've seen chips wedge in there (the little bitty one halfway up, not the big one in the tip) before and result in plenty of fluid flow, but no pressure.

no i think its out of an 81 chev truck without hydroassist brakes.
in the writeup in the tech section there is a pump section....that sounded wierd.....it lists the pumps and specs
