Many farmer's have used this trick for years. They utilize the power steering pump of the vechicle. If anybody would like to know how it's done just ask.opcorn:

i am glad i finally had this topic come up..we were talking about it recently at work and, nobody believed me about the concept working or having enough ummph....i wasnt 100% sure if my truck would have enough "guts" or not either
The truck is a 1978 dodge D100 w/ a 5.2L 318 COULD this be enough to convert it to a dump bed? A FRIEND GAVE ME A HYDRAULIC RAM,AND HOSES how many other items do i need? valve, tank,anything else? thanks in advance for any info..............................Scott
used the air conditioner pump to compress air,
I did thison a 76 Dodge I had. Use the stock V twin AC pump, modified for some oil in the sump and it worked pretty well. Added some small tanks uner the back outside of the frame rails, and a quick connect plate just inside the tailgate at top of be, with a QC to plug in hose, a schradre valve to fill the tanks from home, and a small pressure gauge. Sure nice having some air to impact tools around farm equipment. It was slow, but could charge up then get a few seconds of good tool usage, which was usually all I needed until I did soemthing else int the repairn and needed the air gun again.
PS pump: Most are about 750 to 1200 psi vane type pumps, so you need to account for that in the lift calculations. Also, usually only 1 or 2 gpm. Revving the engine doesn't help either, as PS has a priority flow divider inside the pump to give a constant flow whether parking a car at idle, or going down highway. If it was regular pump output where flow increases with rpm, the car would steer like a gokart at high speeds!
Figure the pressues and cylinder size, and estimate the time to lift. If you go ahead, you will need a tank large enough to make up the volume of the single acting dump ram. Lot of volume there. and add a good return filter.
How about a clutched hydr pump dedicated to the dump? Surplus center has them not cheap, have to mount v belt drive, etc. and horesepower limited by the vbelt drive, but just using asmall er pump at higher rpm. The pto off the transm uses larger pumps at slower speed.

what you want is a 97 dodge cummins power steering pump with hydroboost. this pump powers brakes and steering. a little tricky to hook up drive gear
I think GM has the same, and they are belt driven, or ford, dont remember, But the eariler ones were belt driven, T,C, E,J,
Derbyguy, Are you wondering IF your 318 has the guts to run a hyd pump,? You runnin about 150 hp plus right? IF so you could run about 50 pumps at a time, or did I miss understand your question,? T,C, E,J,
the question was if the stock power steering pump has enough guts to work for my specific application(dump bed) in regards to the 318, MOPAR=MORE POWER

WELL....I've personally used them on 3,4, and 5 inch cylinders, I tell ya if their Weak I wouldn't know it. Now I will say and sombody touched on this earlier, the relief setting is important, as is the orfice on the oulet. You really need to know your application before expecting great results. On GM pumps the orfice control's alot. The guy earlier also said get one off a truck, I agree, they tend to have more pressure and volume, and capicity in some instances. the only part I disagree is on the resivoir. I tried the (Through the return) method first and What I found was the fluid wouldn't equalize to the pump fast enough. I ended up mounting the res. higher and running an 1 and 1/4 inch hose right over to the fill cap neck from the res. Now this could be because my res was lower about a third to the pump, but I watched it through the fill cap and it was really slow returning the pump. A person needs to check the avaliable pressure. I've been told (By a reliable source) that ford pumps have less pressure. True, I can't say. the other guy was also right about needing more fluid on hand(A RES) expessually when using one way hydralics.
