I am setting up hydroboost with full hydraulic, the oribital I am using has an aux. port. I plan to run the brakes off of the aux. port of the oribital.
This will give me 3 lines of return.
1 from the oribital.
1 from the hydroboost
& the pressure line out of the hydroboost that was feeding the steering box.
Question;
Should I just return the pressure line from the hydroboost back to tank or since I am not using it can I just plug it?
If I plug it will it be running over a relief in the hydroboost ?
If I return it it may creat to much back presssure in the system?
Any suggestions?
thanks
 
you need to make a full circle with the hydraulic lines. So, if you don't already have a return from anything in the system, you'll need one. I'm not very familiar with the hydroboost, so I can't add too much help for that.
 
I have the circle.

thanks.
 
I fired it up last nite, seems to run fine. Pump whines though, it's a used pump & don't know how many miles were on it. I'll get another pump this weekend & see if it quiets down.

I am running the return for the oribital & the hydro-boost into the cooler then to tank. The pressure port that used to feed the power steering boxis run straight to tank.
 
Give it time to get the air out of the system. I have had pumps whine, but after cycling the system a few times after some running it will stop or at least quiet down.
 
Let the air settle out, started it up & it worked well for about 30 min. then at an Idle lost all steering, rev. it up 200 rpm & it was back.
So the hell with it & got a new pump & did the modification from here http://westtexasoffroad.homestead.com/powersteering.html
I did boost my pressures not sure what the pump is relieving at but my oribital relieves at 1750 psi. I drilled out the valve to 1/4"
Ran it last night for about an hour everything was good & hot, never lost a bit at the wheel.
 
glad it worked out for you,on my rockwell yellow buggy(nothin fancy) i drilled it out to the 5/32nd,stretched the spring to 2 inches and it worked great,i could steer it at an idle without the steering wheel attached,by just twisting the steering shaft by hand,my stock GM pump had almost 300,000 miles on it.this was with a 9.7 orbital,2x10 double ended ram.
