Trying to get my steering setup, and i think i may have it backwards.

which port is the "IN," and which is the "OUT" on an IFS steering box?

in is the one that is closer to the tire

EDIT: Just in case that wasn't clear enough, looking at the input shaft, in (high pressure line) is on the left, return is on the right.

thanks

that is the way i have it, so my problem must be something else.

i installed a hdroboost brake booster and GM 4 wheel disc master cylinder. i'm running a saginaw pump and i can't seem to get the system to work. i've blown up 2 pumps already. the first one never seemed to work, and second one lasted for about 5 minutes. just got finished cycling the steering to bleed the system, then stepped on the brakes and BAMM, no power steering - blew the pump

can a saginaw pump cavitate so bad i blows up?

Why the hell would you swap in a shitty hydroboost system? The only reason they use them in diesel rigs is because there is no vacuum for a real booster.


Just curious of your intentions.

hydroboost swap reasons

well, i was told that the hydroboost units do work better than a standard vacuum booster.

also, this is in a samarui buggy with VERY little room. i had tubing within 1/4" of the stock "very small" vacuum booster. the hydroboost units only have about a 5" diameter.

my stock booster/master cyclinder was fine until i went V6 and automatic tranny. i just can't hold it back going down hills when in low range (4:1).

Here is what I would try...

Get the front axle off the ground...
Put in a good synthetic fluid, I used mobil1 atf... get the system all back together, fire it up and let it just pump for a minute without moving the wheels, but with the cap off make sure its flowing (you should be able to tell and the fluid will be slightly frothy probably)

Let it run for say 5mins? Then let it sit for an hour or two, go out and start it back up this time turn the wheel from lock to lock about 10 times...Let it sit for a while again, start it again and now try to brakes, by now all the air should be pretty much out of the system...

Least that's how I did it on my yota with a chebby ps pump...

Why not just use the Toy pump since it was intended to be used with that box. I am using the stock pump and have two friends using chevy and ford pumps and they don't seem to have enough pressure. There's has the typical full size belt screeching no matter how tight the get the belt.

current situation

Snake47720,

right now i have concluded that the hydroboost is BAD. i'm on my third pump without ever leaving the garage. but, i don't think any of the pumps were ever bad, they just got "air locked" or something. because, the last time it happened i removed the pressure line and let it pump the system dry. i then re-installed the pressure line and bled system as if installing new pump, and all is fine with my steering, i just don't have brakes. i also can't get the hydroboost to bleed fluid threw the return line. it only spits a little when releasing the peddle. i have been told there should be a little fluid passing through this port when the peddle is applied.

should have new hydroboost on Tuesday. will let know what happens.

thanks for help.
