400 factory power steering

Mlkgsmer · Jul 13, 2012

I'm lost now. Been through remote valves, freshened prongs and damage. Plow lifts awesome now. Been through safety and regulator valve block. No problem there or in dervertor valve. New pump, prongs on supply lines. Factory setup and plug in steering post. 1200 psi at remotes when requested, none St PS motor until remote stroked. Any ideas what I have overlooked? I feel like a dog chasing my tail, except I've passed out and started over several times. Thanks in advance, my brain is fried.

Provided that some one has not taken the aux valves off and lost the plug with o-ring on it , your problem is in the flow divider valve. You said it works when you dead head one of the other valves so that shows that flow divider is leaking past to aux valves. The spool wears the most but bore wears also. I was able to get a new spool just a few years ago, however, lot of parts men don't know how to look up the number as it was originally not a service item but was after they got a few years old. An accurate flow rater down to 3 gal per minute would show your problem in a quick test. I know, not everyone has one, I don't either anymore but I always seem to devise some other type of test to with a hose , a restrictor valve with a gauge on it and a bucket.
