adding remotes to a 1010

First off, I don't really know what I'm talking about here. I'm just reading the Army Hydraulics Field Manual (FM 5-499). Also apologies, because hydraulics questions always get into complicated arguments.

I have two control valves left over from a loader, which were used with a front-mounted pump on my JD 1010. They were plumbed in a simple circuit with the pump and a return line to a reservoir, plus control lines to the cylinders (double-acting). I don't know whether these two controls have a parallel secondary circuit between them, but I don't think that matters. (I don't really need two remotes, but I'd have to go out of my way to hook up just one.)

I'd like to put these spools in my 1010 rockshaft system (belly pump) to create two remotes. Can I install these valves in the high-pressure line (from the belly pump) in series with the rockshaft (spool bypass output to rockshaft input)?

I'd use the remotes for things like a wood splitter or to control the angle of a scrapper blade. I don't really care about response time with anything; and I won't operate more than one thing at a time (I only got one right arm). The remotes won't do anything that needs to stay pressurized if I use the rockshaft. I'm trying to keep this simple. And cheap.

I understand that I can't deadhead the control outputs because this is an open-center pump. So I'd want a pressure bypass between the control outputs and the return flow (to the rockshaft), or at least a way to hook the control outputs together if no remote is attached.

I also understand that the controls and any attached remotes would need to handle the pressure of the pump (upstream). If I don't operate the spools and the rockshaft at the same time, I don't think I'll have any issue with downstream rockshaft pressure wrecking the spools.

Finally, I get that using the remotes could decrease pressure in the rockshaft input; but I think any 3-pt load should remain static if I don't move the quadrant.

I know JD offered a remote, but it's too rare and pricey. I need to study it more, but I suspect it's a power beyond setup with the remotes downstream.

Am I seeing this right?

(Apologies if this has been hashed out before. I searched but didn't find it. But sure found lots of related hydraulic chatter.)
 

IIRC all you need to do is locate the hyd pressure line(see photo) from hyd pump to 3 pt control valve & attach an open center spool valve with breakaway couplers in series.

Yes you can easily add the spools to your 1010 as long as two criteria's are met.
1. They are open center
2. The spools have a pressure relief valve built into them.

When using the spools it would stop all oil flow to the rockshaft housing and divert it to the remotes. The rockshaft would be stable and not drop as the valve is closed. It is important that the spools that you install have the pressure relief valves built in to it as if you are raising an implement via the remotes the oil must have an escape route once the cylinders have reached max travel. Yes, it is simple enough to let go of the lever, but we all hold the lever and extra half second or so. With out the pressure relief valve you run a huge risk of building to much pressure and breaking the hydraulic pump, then you will be SOL.

Early 1010's and late 1010's had different pressure setting. With out looking at my JD service manual I think the early 1010's were set to 1150 PSI and the late ones were set to 1400 PSI.
 
Thanks. These spools must have pressure relief because it was the same issue on the loader. (It was a JD loader.) They are four-way, three position, center-return spools -- I don't think there's a float. Everything is open center.

To simplify the plumbing, I'll re-route the pump output line to the right side of the tractor -- the rockshaft housing apparently has an input port on each side. A PO replaced the pipe with a hose, which I already replaced with a new hose. I already have a place to mount the spools and quick-connects. I basically just need five short hoses and four quick-connects. And then all the actuator stuff -- I also have cylinders, but they probably need to be rebuilt. I know I need to limit the actuator volumes.

This should be easier and cheaper than messing with that second (front) pump and a whole new system.

Thanks again.
