Hydraulic Valve Options

[Spencer]

DFB,
I am just wondering how many remotes you have there on the rear of your tractor? I just added 1 set of remotes to operate a hydraulic toplink. You seem to have quite a few more connections on the rear of your. Is that 2 complete sets of remotes, or more?

This is how its set up. In the pic <A target="_blank" HREF=http://www.tractorbynet.com/forumfiles/37-85452-scvrightside.jpg>scvrightside</A> the lower two outlets and the large looped hose is the JD factory aux hyd setup. Flow comes out of the upper outlet and returned thru the lower outlet. OUT/IN.

Now in that picture the fender mounted control valve remote circuit is isolated from the continuous flow at this point.
To get flow into SCV the hose that leads to scv (the one outside the ROP, connected upper right) is swapped with the main outflow return line. The upper right outlet then becomes the return from the SCV and the upper 2 outlets on the left are the remote outlets.

It could have been plumbed differently direct to the SCV with no quick connects, but lack of space, hose routing etc. made this setup more viable to me. Also the main outflow outlet can be used to feed another valve if need be.

Are we saying the same thing here? From your post I read that the supply port is the toward the rear of the tractor, and the return port is toward the front of the tractor. I plumbed the rear port (what I understand to be the supply port) to the port named "in" on my valve. Thanks for the clarification.

Jim here's scan of the aux kit from Deere. Shows the hose connections. There's also a plug installed. See # 19

DFB, is the plug to be INSTALLED or REMOVED to enable the power beyond operable? I am gathering that you bought this as a dealer-installed option, then added your valve to it.? I also have a call in to the local dealer, who is calling JD service, we'll get to the bottom of it, and I will follow up with what they say.

Jim, the JD kit included all the numbered componets in the scan. With the kit a new outlet plate comes with the plug installed and replaces the original one.

Now according to the parts manual the original plate that comes on the tractor and the one in the kit have the same part number # M808034.

The part number in the manual for just the plug is #PT13744.

Looks to me like it may possible to gain access to the plug cavity without removing the DSCV and plate by first removing the green plastic cover below the front of the seat and then the 2 pins and 3 bolts mounting the bracket for the joystick handle to the DSCV.

Jim I'll scan and post a followup picture of the control valve linkage.

Here's the scan.

DFB, Eureka!!! Thanks to your guidance and a little prying at the local dealer, I have power beyond. I called the dealer and explained the whole thing to one of the techs, and at first he kind of said he didn't know but later called back and agreed that it appeared that the plug (as DFB called out part number PT13744) was the key to making it work. He told me he could not "spec it out" to tell me what size it was, but then he said since it was only seventy-two cents, he went ahead and ordered it for me. He called the next day and had it.
As DFB suggested, I went in through the front, under the seat. I had to dismantle the DSCV lever assembly. After that, I removed a cap in the block and screwed in the plug. Replaced the cap and that was it. Reassembled everything and my system worked.
Here's an attachment showing my new Prince LVR and some of the plumbing.

Here's another view of the valve. My Thanks go out to Kevin and Kerry at Princedirect.com, for their technical help and fantastic price on the LVR. This valve worked out great in the small space I had, as it is all in-line, with joystick out the front, and all ports out the back.
If you're wondering, the "extra" hoses you may notice are feeding some tractor-front mounted couplers, "T"d to the back too. There's also an "extra" coupler on the oil return line (thats why you see five couplers) because Kevin told me I could operate single acting cylinders with this valve if I plumbed the unused side of the spool to the oil return line. So I will make up a jumper for this purpose. Cool, dump trailer here I come...

Here's the operator position, to show you how the joystick falls perfectly under your right hand. Even better than the stock DSCV, actually. The Prince LVR forms an armrest (needs padding yet), and the handle is right under your hand, if you are looking forward. If looking back, you slide your hand back on the handle a bit and its just great there too. The LVR is much more meterable than the stock DSCV, finer control is possible. Probably 'cause its a much bigger valve.
The bracket is custom-made, designed to raise the valve 2 inches for acces to the power beyond port on the bottom of it, for next years Caddigger.
