Modifying the PS pump for my Ram

[JohnJohn]

My PSC ram works but I noticed at low RPM its not working as good as i think it should. I am running a rebuilt Saginaw canned ham pump with a 6" pulley.
I noticed Wild Horses sells s 5.2" serpentine pulley that should spin the pump more at lower RPM.
I also noticed there is some info out there to drill out part of the pump and even add a washer for more pressure but I am curious what adivse you guys have.

I haven't done power assist on my bronco yet, But I have done it in the past. The drill out the restrictor mod works well, shimming the pressure spring just made more heat for me no real help. The best thing I did was switch from #4 high pressure hose and fittings (all 3 of them) to #6, and I drilled out the fittings a little more. I always wanted a smaller pulley but never got around to it. Good Luck.

what pump were you running?

I've done a whole bunch of those, very simple process. Remove the fitting that the high pressure hose screws into the back of the pump. Be careful there is a spring behind the fitting and it will fly out if not prepared. Drill that fitting out to 3/16". On the end of that fitting you will see a small hole on the side, open that hole up to the end in a slot remove the washer and reinstall and refill the pump. That will give you more than enough flow and a slight bump in pressure. If it still doesn't keep up the restriction is in the box it's self.

Saginaw canned style. Previous post is what I did but I wound up putting the washer back in.

Pretty much what Yeller said. I've done the same mod on my Saginaw with the WTOR Redneck Ram setup and I can turn my 40's with one finger any time. If you're full hydro I would think it would help a lot.

My flow piston had two washers. Remove both or remove one?
