bleeding a powersteering pump???

[aj_tatted]

is it necessary to bleed a powersteering pump?

and if so how do i go about doing this?

i put a new one in as well as a steering box and it seems to have air. hmmmmmmmm /forums/images/graemlins/doah.gif

Take the PS belt off and spin the pump backwards. This should bleed the air from the pump.

You must jack the front wheels off the ground and then turn the wheels from left to right about 20 times and it will bleed out any air. For whatever reason the wheels do need to be off the ground.

o.k,..next ?,....i finished my crossover steering and with that 2 wheel drive box in,...my steering is crazy easy.

i already tried adjusting the adjustment screw on top of the box alittle (i didn't turn it much do to the fact i don't want to burn this box out) is this the only adjustment that can be made? /forums/images/graemlins/bow.gif

With truck on or off?

With truck on or off?

on, or else the pump wont be turning and be able to self bleed.

As for having the wheels off the ground, I have never had to do this. I just turned the wheel full lock to full lock multiple times, occasionally checking the fluid level, until the whining stopped.

no truck off at first.

wheels up off ground turn few times till fluid level goes down and then top of. once it wont go down anymore then fire up and make sure it dosnt go dry. then running should be just fine left to right.

if you get to much air in the pump and fluid it takes a long time to get it out and also can hurt the pump with air in the system.
