Post by: Captn. J on April 08, 2011, 10:12:45 PM
i have hydro steering on my yellow thing .... just sometimes it turns fine  sometimes it dont    i m running 42 in tires and  i ve added  tranny cooler for extra fluid for the hydro.... just its off n on thing  i wanna steer like butter  ;D

Does it do that even on flat level ground? At low rpm..? When does it seem to happen the most? I'm thinkin its either runnin out of fluid in a tilt, or its got dirt or a bad o-ring/seal/valve in the orbit part..

how do i clean or flush it out?

to clean the valve its all gotta be torn down... pain in the mooner     lotta little parts!    is the fluid looking frothy at all? resivour is probably too small.. running outta fluid

frothy?   explain that .   and yeah i m thinking too small but i m running it with tranny cooler to get some more fluid

is it all pink and bubbly.. does it over flow all the time?  like if you shake up a soda...     called cavitation, when fluid gets low and it forces air into the fluid.. makes the hydraulics spongy, no response, can end up killing the pump in no time...

yeah its pink n bubbly ... other than tranny cooler   what can i use? i guess i ll give that ac consendsor another try to see if i can fit it in there  ... thanks   the ac consender s like 4 times bigger than what my tranny cooler is

hit up a few scrap yards.. on some GM vans, and big blocks  they ran an extra resivour for the power steering... i run a radiator hose up from the top of the pump, to the extra resivour.. you'll get another 2qt in the hose, and another half quart in the resivour..  you'll have to do some "low income engineering" to get the radiator hose to fit snugly. few small pieces of hose over each other should work. You will need to block off the return line on the PS pump itself, and route it up to the extra resivour.


Once ya get that done.. jack up the front , WITH THE ENGINE OFF and steer back and forth a couple dozen times..    i reccomend doing this after it has been sitting for a while, couple days maybe.... This will let the air trapped in the cylinder and valve escape without forcing it back in by running the pump.

Heres a picture for refernce from when i was tearing my s10 apart...

i m havbing problem again   i thought i fixed it but  i took it out for the first mudbog it steer like a byTch  ...  new powers teering pump and almost 1 gallon resevior and i still cant steer  , i m thinking i have a bad  hydro ram?  will that be a problem?
Title: Re: hydro steering
Post by: Eroq on April 24, 2011, 02:11:59 PM
what do you mean ???   still doing the same t hing?     your valve has 4 ports right?  does it have a 5th port on the side? probably blocked off?

what size diameter cylinder are you running? and what size tires?
Title: Re: hydro steering
Post by: Captn. J on April 24, 2011, 02:53:42 PM
small  cylinder that i got it with ... maybe need a bigger cylinder . i dont see any 5th port. i ll check and my tires re about 40-42's
Title: Re: hydro steering
Post by: Eroq on April 24, 2011, 03:00:15 PM
looks like a tiny cylinder.. like 1 1/2 or 2"    i'd try steppin up to a 2 1/2" or 3"   it'll be a world of difference!   Some valves had a 5th port which is a drain, valve leakage comes out of it, if its plugged it'll feel like its binding up.   

larger cylinder will have more force, you'll run less pressure and be easier on the pump. not to mention you wont have to fight the wheel to turn!

ok thats what i m gonna do   get a bigger cylinder .  i just checked   just 4 ports  no 5th ones

yea your ram was pretty small compared to some other trucks

went to tsc and got me some bigger one and now i m unsure    can anyone post some pic of yours how they re mounted n all   i got 10 inch stroke ..   pic will help me to get ideas on how i  m gonna fab my new one on

there suin in one of the garage tech posts its stickied to top eroq did it shows exactly how to mount it

Did you mod the pump for more pressure? I used a cylinder off a combine and it worked awesome. Never ran a cooler or a reservoir.

i cut up 2 old hitches.. 1" holes   welded em up to the axle :)

does it matter what stroke i got?  i have 10 inches ... my old one had 10 too  ...

if there is more travel in the cylinder than in the steering  it can break stuff  bif there is no relife valve in your orbit valve but the 4 port ones have it built in on most   the bigger the cylinder the more oil ya have to move to make it work some  orbit valves are made for specific cylinders to work properly   when i seen ya wheell it at bondy it looked like ya hade to turn a lot of turns of the wheel to move it check yer fittings and make shure there not a restriction fitting with a small  inside diameter  that will restrict the flow and make it slow to steer

You want a cylinder match for the psi of the pump too.

Post by: Captn. J on April 27, 2011, 03:34:42 AM
it steered just fine before just it now dont want to steer  and i m sure the ram i had was bad or going to be .. i m gonna give this a try n see.

The restrictor will look pretty much just like a flat washer, and it will be stuck into a fitting. Like nascar restrictor plates. Also, ppl remove thermostats and put in big flat washers to restrict coolant flow so coolant will stay in radiator long enough to be cooled.

i guess i got everythinfg ready to be mounted on tomorrow or friday   so again i m asking is it okay to use tranny fluid ?   last saturday at a bog someone said to use hydraulic oil  not tranny fluid ... so i wanna make sure . i m okay with tranny fluid if works the same
