full-hydro, which orbital?

[Tacoma747]

I have two orbital's, which should I used for my buggy?

One has 4 fittings on it, one has 5, other than that they look about the same.

From what I've found, the 5th can be used for "optional" hydraulic functions, such as rear steering.

I don't plan on having rear steer, so is there anything that that extra fitting could be effictively used for?

Thanks

A hydro powered blender.

maybe I can mount a hydraulic jack to each corner, plumb them all together, then when I need to change tires just flip a lever and the whole buggy will raise up

Blender would be easier...

Really it's a shot in the dark with either of them, unless you can get somebody to look up the numbers (if they have a tag)

They may or may not work, could be 1 turn lock-lock or 10, might overheat your pump (I can't remember what it's called, but not all of them will work with an automotive PS pump). I've tried some, and the wheels turn when the steering wheel is not turning.

You may be able to just block off the 5th port, I've read that works sometimes. I tired it on one, it didn't.

There are hundreds of different speced valves, only real way to find out is to hook it up and try it. Good thing is, *most* of them mount the same.

If it's a charlynn valve, look here http://www.sophtech.org/PDF Files/Motors/Parts Info 211-212-213-241-243.pdf

It cannot be closed center, for figuring the orbital size this seems to be a well thought out program http://www.pirate4x4.com/tech/billavista/PR-Hydro_Steering/Steering.html

A search on yahoo using the part number worked for a few for me, thats how I found the above link.
