Power steering pump for hydraulic pump??

[rkevins]

Has anyone tried this ? I am think of building a powered dump cart from a old mower and would like to add hydraulics to dump the bed, I have a 10HP motor that will drive the trans. will a power steering pump work laying down?
Thanks for any help.

as long as the resivoir (sp) is in a good position i would think that it would work fine. there are many import units that have remote tanks

My Jeep uses a MileMarker hydro winch that runs off the OEM power steering pump....works great for the past 7 years.

late 80's-early 90's chevy astro vans have remote reserviors for the PS pump.

theres always tons of them in the junkyards around here.

I wonder if you could extend the filler neck elbowing it up and build a tank on it

still going to be running ps fluid in it? not sure what that will do to the seals in the lift bed...

Dynamic tow trucks (the back part) runs off trans fluid to speed things up... was to slow with #32 in the winter..

IIRC, PS pumps put out a fair amount of pressure, but are a bit low on volume. Slow lift.

They're low on pressure too, under 2k iirc.

Lots of integrated reservoir ps pumps out there though. I think it'd work just fine if you know what pressure/flow your working with and size your cylinder appropriately.

I have seen pumps that are internally regulated between 900 psi and 2000 psi, so there is some variance. A lot of the newer GM pumps are around 2.0 GPM, with the truck pumps largely being 3.0-3.5+ GPM. This link should get you started:

BTW, those truck pumps are easy to rebuild for higher pressure and volume. Lots of off-roader guys do it to their 4x4 rigs.

I recently had to rebuild a GM/Toyota pump (from a 2004-2007 Cadillac CTS-V) to match the volume requirements and pressure limitations of the rack in my Jaguar. I called A-1 Cardone, a company that remanufactures power steering pumps, and their techs were able to give me the PS volume and pressure of their rebuilt units, which in theory, should be about the same as the stock units. With that information, I was able to go to a salvage yard and buy an old pump to tear apart for parts.

Let me know if you want more info.

id just say, know what kind of pump your getting, just make sure its a regular old power steering pump, some of them i have came across have a variable displacement, where they displace less fluid at higher rpm, to try to use less engine power when its not needed. i cant remember exactly what models but they were just passenger cars that i saw like that.

Hello Folks,

I have a PS pump off a 99 Chrysler LHS running some cylinders.
1) I took the pump apart and flipped the vane assy around to change the direction it runs.
2) Shimmed, the pressure relief for max pressure.
3) Added an adjustable pressure regulator.
4) Ran the pressure side to an A-B valve.
5) Took the dump side into a cooler to keep the fluid temp down.
6) Add a 3 gallon tank above the pump to keep it feed.
7) Its runs sometimes 3 - 4 months none stop. I build it in 2002 and has worked fine.

a properliy sized hydraulic suction hose could be clamped on to the filler neck then plumbed to the bottom of a larger resevoir to add capacity if needed.

We used to put them on snow plows,slow but, they worked. You would have to rev the engine. Im sure with the right pulley size they would work better.
