remote possibilities on 674

My 674 has a single remote, and I'm thinking of ways to add more spools. I know I can search out more valves for the stack and I get the power beyond plate. Is it not also possible to remove the one remote I have now (well, the whole stack), change the fitting on the inlet of the rockshaft housing, and add a whole new stack/valve with however many spools as I want? I can see a need for a bulkhead fitting or bracket and hose to connect where the line from the MCV valve currently connects remote stack/aux mounting plate. The odd fitting where the remotes feed the rockshaft housing appears to be ORB, and the line running to the remote stack from the MCV is JIC so getting things connected should not require any special blocks or manifolds.

From what I can tell, I can take an open center valve stack, plumb the line from the MCV into the IN port, plumb the OUT port to the rockshaft housing and be on my way. If the new valve/stack has power beyond, I'll have to run a line back to the reservoir, but without power beyond, I'll only need the stack (and hoses/fittings for the actual QCs out back), a fitting or two, and some hose to get it sorted.

Or am I out in left field?

Hi, power beyond adapters is the IH way to do it but very $$$. The other way to do it is to tap into the pressure line that comes out of the remote control valve and goes to the depth control model under the seat. Unfortunately to access this 90 degree fitting on top of the remote control valve, you have to lift off the deck that the seat is connected to. The tube that you remove is called the "auxillary valve return tube", it is sort of an L shaped tube that goes from a 90 degree elbow on top of the remote control valve to the drapth control under the seat. So the in line to your new vlave unit would connected to the 90 elbow and out to the draft control port. Some installations cap off the drapth control port and put the return into the hydraulic drian plug under the right axle housing.

Hope this helps

I think I just figured out why your post didn't make sense to me. My tractor appears to be a euro version. I have lucas electrics and my remotes look like the one in the euro breakdown. It is also a grove vesion with floorboards unlike any I have seen elsehwere. If you take a look at the aux valve breakdown in euro, you will see the ORB fitting I was talking about in my first post. It is #24 and part number 529705R1...that also shows to only be used on euro tractors. Are we talking about the same spot where the hydraulics from the remotes goes to the rockshaft housing? And if so, does my original idea make sense?

I can take a pic as soon as I find my camera. I just so happen to have the deck off while I'm doing a PTO job and generally cleaning all the crap out of the trans housing from a dead parking brake.

Hi Tipper, I live in Canada so our 74 series tractors are sort of Euro with Lucas electric.
Look at parts for 3230 (just newer version) page titled "Remote Auxiliary Valves 1st." The tube I am talking about is item #18 going from aux valve assy to back of draft control assy under back of seat. Does your 674 have that tube?
I am fimiliar with this because two years ago my brother bought a 3230 and we moved his 2250 loader from his 495 to the 3230. He also has 454 and 684 and they all have the same tube item #18.

No line like that. There is one fitting on the remote block, and the only line I have going to my remotes (aside from those for the cylinders) is the one coming up from the MCV behind your left foot. It comes up and ties into the block (the equivlent of the #7 in the breakdown you directed me to). Where the #8 o-ring goes in your breakdown, I have a tapped hole for a 8 ORB fitting. The original fitting is a nipple with an o-ring on it that the remote block slides over. From what I can tell, that is where the pressure goes when the remotes are not in use. It must be since this isopen center, and I don't have any other place for it to go. Yes?

Took two pics. Unfortunately they are not going to show the valve actually on the tractor since I have it off at the moment. First pic shows the remote stack from the rear. That open threaded port is the only place for a fitting other than where the lines go to the cylinders. The second pic shows where the valve mounts with all lines still in place. I did change out the original nipple for one with a JIC so I can...possibly...hook up a hose and bypass the remote stack until I add my own stack with more spools.

Tipper, your 674 is different. Yes, you could tap into the pressure line coming from MCV valve.

So now I guess I need to figure out exactly how many spools I [i:c84a8b8ba8]need[/i:c84a8b8ba8].

JimB, thanks for all your help on this post and the other one from a few weeks ago.
