260 loader controller

I have a loader controller for a 260 loader. I installed a power beyond block. From the loader controller which one is the in and which one is return? I know what is what on the block but its not indicated on the controller? There are two parallel ports on the top of the valve controller.
 
It looks like DEERE used at least 3 different spool valves in that control box. Lacking any further documentation on what you have, can you look at the "in" and "out" ports on the actual control valve and follow the plumbing from there to the two ports passing through the control box?
 
Not really? the spool just has two unlabeled ports on the top of the valve. If you call the long side of a rectangle the top, there are two parallel ports. Coming out of the same side towards the bottom is the valve control cables. Facing towards me is two rows of three loader supply quick couplers. If it makes a difference... one hose is a larger diameter than the other hose on the "in" "out" ports. What happens if i hook them up backwards. JD Shop manager said they should be labeled in out, but there not. What happens if I hook them up backwards?
 
Any manufacturer"s name visible on the valve... if so, a "net search might turn up how the ports should be labeled.

The smaller hose is "pressure", and the larger hose "return" 90+ % of the time, UNLESS someone has been able to muck things up and figured out a way to reverse them!

ONE result of hooking them up backwards will be lots of pressure on the seals at the end of each spool.

Since this is a closed-center system, it does not have a relief valve in the block you are adding.

If it were an open-center system that would be a BIG problem, "cuz hooking it up backwards can break the pump, the valve or blow lines because of the relief valve not being able to function!
 

What are you planning to power from the PBY on loader valve? No PBY is required on closed-center system just tee into supply line and return oil to sump.
 
my last loader was installed that way, except I didn't return it to
sump, rather a ported filter return . Due to the hypothetical
problems of a sump return and pump starvations. I went through a
pump rebuild and speculation was the loader plumbing. The power
beyond is the same principal but cleaner. Whats the issues with this
install.
 

What are you trying to operate off of the PBY on the loader valve??????????? I seriously doubt that a FEL valve plumbed to a 40 series tractor to dump oil to sump caused any hyd failures IF hyd FEL valve was a closed center valve.
 
PBY block is installed on the 4040 remote. high pressure line going
to loader valve. Return from loader valve to return on PBY block.
This is what was suggested by JD and my mechanic. Its simple.
The PBY doesn't tie up the remotes for hay processor and PBY
powers loader. Whats the problem with the configuration. Id really
like to know if its wrong now.
 
It may have if it still had the old style paper
filter in it I have seen then all chewed up from oil
hitting them then any trash that was in the filter
goes threw the system.
 
The PBY block seemed like the only hassle free install, but if there is an issue with it being done this way, id like to know? Thanks
 
There is nothing wrong with using the power beyond block that is what they were made for. We have 4 of them plumed that way I will check 2 of mine in a little while to see which hose is return Is the valve a JohnDeere joystick?

We have the same setup on our 4240. Just walked out and looked. On ours, the outside port of the valve is connected to the top of the power beyond block, and the inside port is connected to the side of the power beyond block. This comes with no guarantee to be right, but works good on our outfit.

So "outside" the one closest to you as your looking at the unit is supply and inside or the one closest to the tractor frame is return.
That sound right? Thanks
 
That is how ours is hooked up. I'm just assuming the valves are the same. The cover is on ours, but everything looks identical.

I was trying to understand your first question about PBY on loader valve. I now understand what you're trying to accomplish and WyoDave is correct. This is the PBY you were referring(R54312 MANIFOLD parts key #4) but they're also PBY fittings that screw into FEL valve and that's what I was thinking you were referring to.

The only concern I have now is that the out side line on mine is the larger hose and inside line is the smaller hose. If outside is supply and inside is return, then according to bob the hoses are switched and the larger line needs to be switched to return side. I wish there was a definitive way of determining correct in and out. thanks jason
 

According to this utility tractor schematic the top port on the hyd valve(should identical for RC tractor) should be the "IN" port and IIRC that's 100% correct.

Yeah i looked at that chart before, but mine has two parallel ports
on the top of unit, I posted a picture earlier. That chart doesnt
seem to resemble mine. I could take a better picture showing both
ports together> Thanks Jason West
 
Parts catalog shows DEERE used HUSCO, Eaton, and Cessna valves on those loaders.

Yours is CLEARLY the HUSCO. I am almost certain if you look CLOSELY at the end block of the valve where the ports in question are, one will be labelled "T" for Tank and the other "P" for pressure, probably on the "top" side, facing the green box. Letters will probably be kind of hard to see as they are cast into the sand-cast block.

okay I just tore the valve out and the inside one is marked in and outside one is out. So the small hose is on the out, soooo... should I swith the larger hose over to the out for return and smaller hose over to in for supply. And just for redundancy, the supply will connect to the top port of PBY block that channels to the small hole inside the top of PBY housing and return will dump into side of PBY that dumps into the main part of Block? Last question I Promise! You guys have been so helpful. Jason West
 
Come on Jim you know better. While the Waterloo does have
a better transmission pump than the Dubuques of that era.
The return oil from the loader should still flow into the
rockshaft/Scv line and into the filter side of the trans pump
circuit. Or into a ported filter cover.
 
Come on Glen
I know 30/40/50 & 55 series JD rowcrop tractors have a trans pump that runs non-stop(as long as engine is running) unlike the 10 & 20 series RC tractors(except for PS trans) and returning oil from a FEL valve to ported filter cover IS NOT REQUIRED for excellent FEL operation. Operating a FEL on a rowcrop tractor doesn't require the same flow of hyd oil as operating a backhoe. This is one reason Waterloo tractor hyd's ('73-'93) are far superior to the Dubuque/Mannheim tractors hyd systems of same era.

Actually as long as the return hose size is 3/8 in inside diameter it will be FINE. On most JD FEL valves I've seen/worked on the pressure/return hoses were the same size.
