Hydro Steering

Post by OVERKILL ENG »

Just a question for anyone in the Know.
Just setting up my hydro steering and wanted to get some idea how big a resevior people run and wether they run coolers as well. Was thinking of running at least 5 litres of fluid and an auto cooler.

Hey Guy's...

I have run Hyrdo steer for about 18months now. I run an aftermarket chev pwr steer pump. (AGR). i do not run a cooler or additional fluid.

Works great, doesn't get hot enough to cause steer problems.
However on the weekend at XXRC my pump shit itself. But the pump has been in the truck for over 2 years now. with the old setup, not just the hydro.

I am just going to reco the AGR pump, & throw it back in.

hyrdo?
hyro?

man...... i swear im the only guy with a 4x4 that can spell hydro (hydraulic) 8) and i aint got no hyrdo on me rig :( i think pistol pete took the wrong truck home :P

welcome newbie!!

in my hydro (hyro ram assist) test, i was having moments, and even with a cooler it was boiling, i have a 5 litre res at home, and stuff, that should do me

anyone thought of using those electronic pumps off subarus for hydro rear steer? :?: wonder if it would have the grunt?

The problem is that the standard pwr steering box ( be a 40 series box, 60 / 70 or 80 series or even a chev box) they all generate a lot of heat. which causes them to boil. give them ram assist as well & i think it would generate even more heat.

If running full Hydro, you should not need a cooler. i think my truck has proven this. even extra fluid has not been required!!!!
It would not hurt to have it. but when you jam a 454 in the sucker, you start to appreciate very compact accessories.... & avoid adding unnecessary equipment.

BJ,

I think why yours boils is maybe because you are running hyrolic assist and you are trying to jam a lot of fluid through the very small valve in your stock PS box. So I think that you are going to need a cooler.

I guess in Pistol Pete's case with running full hyro he doesent get the heating problems cause its a full hydraulic system and not some bootie fabbed POS like yours.

Maybe??

Ran my hydro assist for the first time at XRCC, put it on 2 days B4 the event and would never go back. I run all up 5 m of 1/2" ID hose and a cooler that takes a total of 3L of fluid. At XRCC it was Shyt hot and didnt boil, next full hydro, as per pistol petes specs. :D

Interested in thoughts on the electric pwr steer pump idea

Subaru's are not the only car to do this the current model astra and vectra both have electric pwr steer pumps

they seem to wrok well on a small front wheel drive but not sure how they would stand up to the abuse of a 4x4 even with small tyres (compared to you guys)

the pump would be FAWKED n a vehicle that had a locked front and bigger than 31s if it ever came off pavement

i was purely thinking about for the rear, the little pump may be able to hold up to this?!?!?!?!
