Looking to have some hydraulic lines made this week for the remotes to power my Woods BH6000. Assuming there is an industry standard as to which line (pressure and return) gets the male or female coupler, can you tell me which line gets the pressure coming from the PBY on my loader valve?

The line on the right in the picture has the female QC (on the hoe side), and the left is the male. Obviously the length of the new hoses need to be right the first time, and i need to whether the pressure side on my tractor will get the male, or female QC.

Not that i think it should matter..... but this hoe was originally on a New Holland TZ.

Well traditionally, the valve input port is located near the safety relief valve on the valve body. So if you trace those lines back to the hoe valve, you may find the answer to your question. Do you have a manual for the hoe? A parts list diagram or the installation instructions may also indicate which is the inlet and which is the outlet line or port on the valve.

Mike,
I have the manual that came with it, but its not detailed enough to show which hose is the pressure side. I took Ron's advice (thanks Ron) and found the safety valve on the left side (as i had it pictured). Took step one today... unloaded it from the trailer. Drove eighty miles round trip to have two hydraulic hoses made..... joy of living in a small town, what you need is never in stock. A pair of QCs and a pair of hoses for $140 ! Can't wait till tomorrow when i start buying steel to make a subframe $$$$$ !

I did get to make the hoe move under my tractors power though....

Great!! That is exciting I am sure. I see now that my memory was bad--your tractor looks great, it was your loader that you got that looked a bit weather beaten.

Woods also has manuals for their subframe mounts that have pics that may be of use to you as you work on that aspect.

Looking forward to seeing you using your new acquisition. Before the wife returns, right?:D

Just uncouple the two hoses showing, , and apply pressure to the lines very briefly, and feel the one that jumps or vibrates. After you find which one is pressure, plug into your valve system correctly and it should work. You can also swap the quick disconnects if necessary. Another check is to take off the quick disconnects, and aim the hoses into a clean bucket and you will see the one with pressure.

Some units can be connected and disconnected under pressure, and some will not. I think the flat face quick disconnects will connect under pressure.
