Ford 5000 remotes are hinky after loader install

First time poster here. have read the forum for years and usually found the answer i was looking for. Thanks to all for the great information! It has saved me a lot of aggravation over the years.
ok, on to my issue: just finished the install of a front end loader on the 5000 (72-SOS), farmhand 22 loader, 2 spool valve with power beyond. installed power beyond plate under tractor seat under the remote spool. this is the first time i've done this kinda thing and everything worked flawlessly. no leaks, loader goes up and down, 3 point goes up and down. yesterday i had to move the transport disc and hooked it up to the remotes. it was a bit sluggish at first then the cylinder lifted it right up. i waited for it to reach its max stoke and snap back to the neutral position. well, it lifted all the way up but did not kick back to neutral. i manually slipped the lever back to the neutral position and the cylinder lowered. the cylinder would only hold the load if it was in the lift position. needless to say, that ain't gonna work.... i need that cylinder to hold at whatever position i stop it at, that's how it's always worked prior to loader install. any thoughts from anybody? FYI, i am still in amatuer hour so please try not to bombard me with a lot of technical jargon.... i figured how to plumb this thing and repair a leaky lift cylinder so i'm not a complete dummy. :) any input would be greatly appreciated.

I've never had or plumbed one of the power beyond plates but I do understand how they work.
What is the third line connected to going to the loader, all I've ever seen only had two lines, fluid to the loader valve and fluid return from the loader valve, I've never seen a third line before.
 

that's the "power beyond" line. high pressure line out of the loader control valve to all downstream hydraulics.
 
I don't see how installing a power beyond plate would affect the operation of the remote valve. If you had only posted about the failure of
the cylinder to hold the load, I'd say you have an internal leak in the cylinder (i.e. blown seals on the piston).

That said, assuming the cylinder was working properly before you installed the power beyond plate, I think if it were me I'd try removing it
temporarily as a test and seeing if the cylinder works properly again. If it does, there must be something going on with your install, but
like Destroked, my next question would be, where do the 3 lines go to? Specifically, the 2 lines that veer off to the left.

If the cylinder still leaks down after removing the plate, my money is on a bad packing inside your cylinder. It could simply be a
coincidence to the power beyond plate install.
 
as i mentioned the remote cylinder worked perfectly prior to install of loader. thanks for the advice, i wll remove the remote cylinder and check it. the two lines that veer to the right in the picture (left on the tractor), far right is power to the loader control, to the left of that is the power beyond line from the loader valve. the line on the far left of picture is the low pressure return line.
 
Does the plate just feed the loader valve and that's its?

If so you don't need the power beyond at all. From that plate you just need a pressure and return line to and from your open center loader valve.
 
The power beyond plate has two return ports. One of them provides power to the 3 point and remotes. The other just dumps back to the sump.

When you say that the 3 point arms lift, is that with a heavy load or empty?

If the 3 point lifts a heavy load then I can't think what it might be.

If you only tested it with no load on the arms then it sounds like you might have the two return lines from the loader valve crossed to the wrong ports. One return port on the control valve just receives fluid flow from the open center portion of the valve when it is doing work, basically the fluid being returned from the opposite side of the cylinder(s) being exercised. The other return port is the true power beyond port and provides power beck to any downstream implements, in this case your remotes and the 3 point lift. If you had the 3 port plate and a regular open center loader valve the single return line would connect to the "PB" port on the plate and you would plug the other unused port.

Try reversing the two return lines at the power beyond plate.
 
Thanks Sean, you know what's going on here. yesterday morning i lifted a 1,000 lb water tank with the 3 pt, so yes, it can lift a load. both ports on the PB plate and the open center valve are clearly marked "PB". i'm pretty sure they are hooked up right. this morning i'm going to check the cylinder on the remote to make sure it's not blowing back through the piston.
 
after re-reading your original description of the problem, it sounds like something is leaking internally, either the piston seal in the cylinder or the spool seal in the remote valve. If that remote valve had been in place for a long time then removing it and reinstalling it on top of the PB plate could have triggered something inside that that was just on the verge of leaking to start doing so.
 
Again, thanks Sean. That's where logic was starting to lead me. it's cold and rainy here right now so i didn't take the tractor back to the field and hook up the transport disc but i did take a long pry bar and could not get the cylinder to budge. i know that's not the same as 1,000+ lbs bearing down on it. one other small thing i remember about the plate install is that one of the o-rings between the plate and the remote spool was a bit smaller than the recessed hole on the plate. being impatient i centered on the hole and stuck them together thinking if it leaked it would come out from between the two and i would see it, no leak. i'll look for repair info for that remote spool, that seems like the logical thing.
 
problem solved: I completely forgot SOP, better to keep your mouth shut and let them think your a fool than to open it and remove all doubt....
simple operator error. i had inadvertently opened the float knob on the remote valve. that prolly would have been just fine if i hadn't also hooked the remote lines up backwards.
sorry for wasting everybody's time. But after reading all the warnings about plumbing the power beyond plate wrong and ruining the hydraulic pump on the tractor, when something seemed a little out of whack i err'd on the side of caution.
thanks for everybody's input.
