Question: Electric over hydraulic power steering

Exactly BMC. Take Full Load Current(FLC) and duty cycle into account if doing this. A long loop of steel line in the return can help rid some thermal energy too.

I think they are more worried about the motor it looks like a permanent magnet type motor with no cooling. The duty cycle is likely rated using a normal load that is more constant than using for power steering.

It will only see a significant load while braking or steering. It will be seeing a minimal load while going straight or steering with the vehicle moving in 2wd.

Ordered mine this morning. what type fittings are you gonna use on gearbox and hydra booster? A buddy of mine has it on his 2000 gasser pulling truck and it looks like NPT fittings

I already have the Driven diesel upgraded power steering lines that have a 3/8" (-6) JIC fitting on them, so I will just have a longer hydraulic line made up to go from the new pump to hook into the line that goes to the hydro boost than hook the 2 returns into the new pump return side.

Thanks, good to know!

I'm planning on reducing pressure to about 1,500psi first to see how it works, than will adjust higher if needed. Pump is preset at 2,500psi.

all we did was when we got the lines and pump hooked in and filled up with fluid and bled. i backed the regulator all the way off and turned the pump on and had my brother try and turn the wheel back and forth. i kept turning the regulator in (up in psi) until he said the wheel was about as easy as stock to turn. u dont want to risk running any higher of a pressure than you need or u will blow out the seals in your hydro boost and gearbox

Any reason this would have any benefit or anything negative over full hydraulic? Other than the price of course.

I think this is the best option if you want to keep you hydro boost brake system and gain steering power. If you are running a aftermarket master cylinder I think full hydraulic would be a better option.

Ok that's where I was confused, the way I was thinking of going would allow me to go to a smaller master cylinder.

This sure looks and seems easier

I went full hydraulic steering. Orbital valve and double ended cylinder. This is with a welded front diff and single piece passenger side axle. Kept power steering pump to run the booster for brakes. Seemed to work well

 

[kjp800]

Did you need the booster for the brakes? Even with the driveline brake?

I wanted to be sure I had enough
