Hydraulic guru needed...

[teg]

Let me first bow down when I ask for your help... Not sure if you have read this thread? (I'm sure you are tired of hearing about it )

My quest for "Grand" 3 point performance from my "economy" tractor. The L3400

If you have an understanding about hydraulics, could you shed some light on us less knowledgeable TBN'ers... Thanks.

If you don't want to read the whole thing - here's a sample: (ps. ...the "real" help is needed around post #47 and higher. You can skip to the meat of it.) Also, No need to post anything on this thread...

Good though ht1.

I'm starting to discount my theory that it's the spring. Not that the spring isn't important but that other components make the difference. With all this talk about flow restriction I'm questioning how a spring held in place by a retaining spring clip could possibly be stiff enough to provide enough shock absorption to influence fluid pushing at over 2000 psi.

The washer, slowing things down, seems to make more sense.

I don't understand enough about how these things work. How much spring resistance would it take to absorb sudden 2000 psi + pulses of hydraulic fluid?

Then again, having a spring in there, even fully compressed, would limit the full range of motion of the adjusting collar by a significant amount, which also may limit or slow the flow. The adjusting collar appears to be the "check" component of the valve.
