3-Point Hitch 4x20 hydraulic spool change out

[jloven]

I wanted to see if anyone had any advice or experience in replacing a 3 spool valve with a 4 spool valve? I have a 2007 cab 4720 and seem to have plenty of room to remove the current 3 spool valve and add a 4 spool valve like this one (FPS 4398 L239 4 Position Manual Hydraulic Spool Valve, New | eBay)

I feel confident about getting a second hydraulic control handle in the cab along with the linkage to control the 4th SCV. I can mount the 4th SCV on the back easily enough. I am just unsure of how the fitment of the larger spool valve will fit / connect to the tractor....Any suggestions or ideas?

Thanks

The replacement valve has to match your hydraulics open center system AND your hydraulic system flow, which is 12 GPM.
The valve you linked to appears to be a closed center valve.
