Ok so here's the situation. I have a JD 4200 with FEL. This setup has the third SCV ports there with the spool valve but the kit to run it is discontinued and virtually impossible to find (LVBM 19694 if anyone has access to one). Im fairly mechanically inclined but hydraulics are definitely not my strongest attribute. What Im trying to be able to do is run one rear and one forward remote not necessarily at the same time so a multiplier is fine. What are my best options?

From my point of view I can either run a line from the ports for the 3rd SCV and fabricate some type of lever to operate the spool. run it to a multiplier and switch between forward and rear remotes as needed. (Mostly want the capability of a hydraulic top link and grapple).

A few guys have done this, I think on the TBN forum there are some threads about it.

Or (And im not sure this is possible) run an open loop from those same ports to a third party spool valve with two remotes. The question I have for this is, is it possible to have the spool for the original OEM third function always open so that it can go to another spool valve. This would be the easiest option if its possible, but im not sure if that will damage the remotes, spool valve, hydraulics etc.

It would be better to plumb in a new valve via the Power Beyond circuit, not the 3rd SCV, you get better performance and less heat build up that way.

Would love some advice here if anyone has any ideas.

See above in RED.

Also, set up an eBay search for the kit, they do turn up once in awhile.

Thank you! I dont have power beyond installed on my tractor so unless im mistaken there's nothing to plug into. My general thought was if I could somehow replace the spool valve so that circuit was always open and continuously powered a 3rd party SCV kit I wouldn't have to do anything but install lines. Just not sure if there's a way to make it open all the time effectively turning it into a PB setup.
You would remove a steel line and replace it with hoses to create the PB "loop". With the new JDParts though I can't find which one easily anymore :mad:
