powersteering troubles
Last weekend I took out the steering gearbox and replaced the sectorshaft lower seals because it was leaking oil. I only took out the sectorshaft, en didn't touch or open the valve and gearhousing.
When I put it back in, at first it worked flawless, but after about 20 miles there was a significant increase in the needed effort to turn the wheel to the right, to the left it turned fine.
When I drove back from work, it all worked well again until again after about 20 miles (cold/hot??). Then it came back.
At home I put the car with its front wheels from the ground, and with no resistance the wheel just turned fine to the left and right.
But with the wheels on the ground, it kept needing a lot more effort to turn the wheel to the right. I noticed, that if I turn the wheel real slowly, it does turn fine to the right, as if it needs time to build up pressure.
Does anybody have a clue where I must seek the cause of this problem??

There is a procedure in the manual called the "valve spool centering check" to correct an imbalance between torque needed to turn left and right. But since your gear box was probably ok before the seal replacement, I don't think that is the problem.
Did you turn the sector shaft adjustment screw? I would go thru the procedure in the manual to adjust it. I am thinking it is probably a little tight.

I found out that my problem occurred when the enginge is at (almost) idle. A little increase in revs solves the problem, so i think it is the pump that delivers not enough pressure at (almost) idle.... does anybody know how to overcome this? Just replaced my pump 6 months ago with a rebuild one.....
