I am begining a Grapple build on my tractor and need to figure out the hydraulics.
I have a 2 spool currently and no power beyond.
I found a new 3 spool valve with power beyond. I could plum it in where the 2 spool was and get the 3rd valve I need for the grapple.
Is there any reason this will not work?

Fromjb2 said: (quoted from post at 02:38:04 12/16/07) Hi Jeef, personally I never liked using the remotes for controlling the loader. I always preferred the separate spool valves mounted on the right side of the loader frame by throttle control lever. Then you can get the proper spool valve for the loader arms with the up/down and float position. The easy method of plumbing this external valve is to connect the inlet & outlet to one of the remotes and tie the remote lever back so hydraulic oil is always flowing. A more elegant method is to tap into the return line under the seat. To do this you have to lift the deck that the seat is connected to and at the right hand side there is a steel hydraulic line going from the remote control spool valves to the rear of the seat area connecting to the draft control. The steel tubing has a coupling at both ends and can be removed and the inlet to the loader spool valve connected to the 90 degree elbow at the front at the outlet of the remote control valves and the outlet of the loader spool valves to the back where the steel tube was taken off the draft control. The only challenge is to purchase the proper hydraulic fitting to mate with the steel tubing fittings.

If you go with purchasing another power beyond spool valve check the CaseIH parts site to get the proper part number. If I recall some had 2 bolts and some had 3 bolts.

Good luck

I have probably done a poor job of explaining what I wanted to d because I don't exactly know what I am talking about.
What I was planning to do wa replace the 2 spool valve I currently have with a 3 spool. 3rd valve would control the grapple.
I would be removing the old and replacing it. Can't see a reason this won't work but you guys have a bit more experience than I.
Thanks
