Power steering pump hydraulics?

[jlampe94]

I have a 1200 im looking at turnin into a hydraulic lift by running the cylinder and outlets with a powersteering pump. I seen someone has that setup on their 100 and was wondering how exactly it was done, and what you used, and also how it works, pros, cons. From the looks could i just get the cylinder and valve off another quietline-9x series and bolt it on and run the pump off the pto end of the engine plumbing it straight into the valve?

That will work if you do not need the pto for anything else

Yea this is going to be strictly a puller and pusher so no need for a pto, any recomendations on what pump to use?

Here's the thread.

The GM power steering pumps seem to be the most common pump you'll see. The only bummer is that they turn the opposite direction of our motors so the pump will need to be setup in a similar manner to what Adam did. There is a Saginaw pump, a Type "N" pump, that is designed to spin the opposite direction as a normal pump. Many of the mid-late 80's Corvettes with the TPI motor or the early 90's Caprices with the LT1 had this pump and in a few places they say the mid-80's Cadiliac Devilles with a V8 had it as well. You could make the same changes Adam made to his to regulate pressure & have the correct rotation without the added bracketry & mechanics.

Another idea is to take a standard GM Saginaw P-pump and flip the guts around and make it a reverse-rotation. I've only found two mentions of this on Google so who knows if it's really doable or a good idea, though it is an option.

Using a PS pump or a standard hydraulic pump with a separate relief valve & resevoir may be a wash money-wise, though the PS pump idea combines all of the needed operational components into a neat little package and has a better availability of parts if you need them, in the case of a failure on a plow day or something similar. Many of us don't have easy access to hydraulic parts where we live either.

Another thing to remember is that most PS pump pulleys are the same diameter as the crankshaft pulley of the vehicle they are on. So if you are looking to reduce your flow rate you might use a different sized pump pulley to do so. A number of aftermarket companies make pulleys that can flop a serpentine belt pump to a V-belt pulley with no mods.

Search the web. Many of the muscle car forums have great tech data on various topics of which steering components is a fairly common one. Napa also has a huge database of technical data on PS pumps & various things.

Good luck! Keep us posted.

A remote reservoir power steering pump is an option when you want a bigger tank.

ok that helps, thanks guys and does 60 bucks for a cylinder,valve hoses and mounting bracket off a wideframe sound like a fair price?
