New PS Pump...mixed results

I put a new (not remaníed) power steering pump in my Jeep a couple months ago and I replaced the sector shaft and input shaft seals on my steering box (leaking). I also put SWEPCO 715 fluid in. Anyway, Iím not happy with the results. I feel my steering is harder to turn and less responsive. I even hear a pop when I turn really hard right.

My old system was the OEM pump with ATF in it. My box started leaking so I decided to replace my pump while it was apart.

The only thing I may have done was when I took the input shaft seal out I removed the threaded insert to replace the large o-ring. I punched the lock ring and insert locations relative to the housing and put it back together with new seals. Now my steering is less effective IMO.

My question is, does anyone have ideas what may have gone wrong?

Are you asking about the pump or the steering box Louie?

When I went to the hydraulic booster I increased the flow of my stock pump a little bit by drilling out the orifice under the check valve. So far it’s working ok and it’s free to try.
EDIT: It is a Saginaw TC pump if your looking for info on it.

Shaggy is on the right track. Swap over the orifice between the two or drill to match the old one


Forgot what the numbers were for PSC etc. I`ll have to call Blaine and find out. While at it I`ll ask him if that same mod would work with a factory pump.

Good ideas guys. I figure the pump is the equipment that changed, so maybe that should be addressed. Is this the orifice in question?

Ya that was the one I opened up a little bit. In my internet wanderings I ran across some info saying some years of Grand Cherokees use the ps pump to run the engine fan. Is pump is supposedly good for higher flow. I have never gone past internet mining on it so I don’t know how true it is. If it’s true it might be the way to go.

I “think” it was the 2001-04 WJ with a 4.7L but I need to look it up again.

Interesting. The pic is of my OEM pump. I need to unbolt the high pressure line on my new one and take a look.

I’m pretty sure I went 5/32 in mine. You might check west Texas offroad’s Q & A. Section.

Ya it’s not a big thing. I just pulled the fitting out of the pump, drilled and put it back. I did at the same time as the booster unfortunately so I can’t tell you how much of a difference it made.

Going from .125 to .156. Which in a circle is a pretty big increase.

Drill it and run it.
