JD 3 spool hydraulic valve float question
 

I've never taken a spool valve apart and I don't have one of these or I might know the answer to this. I want to add a JD 3 spool valve to my 2072 so I can control my 3-point separately with the float spool.

The question is, can I switch the float to another spool? It would just be nice to have the float in another location based on which valves I use the most. From looking at JD's website, I'm thinking that I can just switch the cap and detent assembly to whatever location I want it. Does this sound right?

This is the 2 spool valve I have on my 100. It has float on one spool. I'm not sure if the spools can be switched or not. The internal porting in the block may be different between the two circuits.

The spool valve itself is different. You would have to switch the valve along with the detent on the end. Without taking one apart I don't know for sure. I do not think that the valve body itself is cast so that the float valve will only work in one spot, but I do not know for sure. :bigthink:

Guess I might have to buy one and give it a try.

If you get one..... Disassemble it and try switching the valves. Then, take an air hose and connect it to the valve to test. Much easier than installing it and finding out it doesn't work.

I was going to use a hydraulic power unit I have, but air is an even better idea.

Less messy. :biggrin2:

Besides.... to really know, you just need flow, not pressure. I hydraulic power unit (assuming you mean a porta-power) doesn't move much fluid, but makes ridiculous pressure.

No, I have one with an electric motor on it. It's for running hydraulic equipment, can be regulated from 0 to 3000psi and has a remote control of sorts to get the operator 8 or 10ft. from the action.

Oh and it has quite a bit of flow and holds 5 gal. of oil. It'll make a real mess in a hurry if you have a leak.

That's cool. Still much less work to test with air.
