Using the SCV opposed to power beyond block??

Reid1650 · Feb 14, 2011

Can I use an scv to power my loader valve as opposed to the power beyond block? Or what are my other options? Does anybody have pics of t-ing into the supply line and returning through a ported filter cover?? Thanks

What kind of tractor? Of course you can, but then won't be able to run anything else. On a AC 6140, I plumed into the main pressure line from the pump, and went through the backhoe valves, then back into the line, When we took the backhoe off simply coupled the lines together. I got scared might inadvertently uncouple it and start the engine and blow the pump up, I bought a pressure relief from Northern and set it at 3000 psi and just let it bypass on the ground, which it never did.

If you got the joystick control valve and you can simply tee into the block on RH that attaches to the pressure line. I know someone will say it needs to be returned to ported hyd filter cover but the loader will work fine unless heavily used to return oil to sump. The 30 series JD have a constant running(pumping oil) trans pump unlike their predecessors. I had a 158 plumbed that way on my 4240 with no problems.

Yes,what tractor? As far as hooking through the SCV,yes there too. I've got mine plugged in to one bank on my Oliver 1600. It just runs through an open center loader valve then right back into the other coupler. I've got it plugged into the left bank,put a long bolt through the bar where the stop is for the 3pt lever,have a double nut,one on each side of the bar,to hold the lever back in position instead of using something like a rubber strap.

JD has a block that goes between the scv and tractor... R54312...you will need longer bolts and fittings and an extension to the svc rod...got to JD parts and do a parts search using that number..I think jd sells it as a kit..have a 4230 and a 4040 hooked up this way....

May I ask what is the advantage of the power beyond manafold and the added cost of the extra feet of (high $$$)hyd hoses that will be required over just teeing into hyd lines?
