I'm running a KSE tandem pump, freshly rebuilt, with a 3 1/2 turn box. The problem I'm having is that I'm getting no power assist until the motor reaches about 3000 rpm. I've tried flushing the tranny fluid and filling it w/ real PS fluid, I've also taken the little bypass spring out of the steering box just inside the pressure hose fitting. Taking the spring out helped, but only a little bit. It's been this way on 2 different boxes, but as I said before, my pump's been rebuilt twice and still the same thing. The guy who rebuilt the KSE pump the last time replaced the bypass spring as whoever had the pump before me had cut off the one that was in there. At this point, I have to assume that for all intents and purposes the pump's new. I can only think that I've had 2 bad boxes or there may be something about the lines between the pump and the box, but the line's bigger than the fittings at each end, so I can't hardly believe that would be it. I've talked to a couple other guys about it and everyone's stumped... thiers all turn at about 1500 rpm.

Thanks for anything you guys can offer..

This is just a guess, but maybe you have to much reduction in your pulley's, if you are 2 to one try 1.5, just a guess.

One other possibility is that there is some binding up in your steering shaft. We had the same problem and it was the shaft between the quickner and the steering box, they were not aligned well enough. That might not be it, but worth checking.

Gnarly, It may be worth your effort to see if you can get ahold of a pressure gauge that you can hook inline. You can contact the proper manufacturer to get the specs. on what the pressures should be. Generally if your pump pressures are okay then it's the box. You will also want to make sure the p.s. line has not collapsed and is not obstructed. The other two post above are also also good possibilities. Good luck,
