John Deere 790
I have a woods 1009 that I am ready to mount on my 790 and need to verify the hydraulic location for the supply and return lines. The supply is coming from the port in front next to the hydraulic "speed" adjuster. The return is going to the port to the right side. I am having trouble finding the information to make sure that this is the correct routing of the lines and have been using the power beyond installation threads as a guide. Any info will be greatly appreciated.

I used the picture in this post to route the supply and the PB from the loader control to the "A" and "B" location and the return to a port below the "A" location directly to the trans. With all three to locations stated the 3 point works but not the loader. with the PB and return routed to trans the loader works but the 3pt will not move until loader is half way in the air. There is a cap screw that the instructions say to remove not sure where on the tractor it is located.

Ok, for anyone looking for the information The plug on the right side needs to be remove and pipe plug (part # 15h275) installed inside before attaching supply line to valve. This diverts the oil flow to the control valve. The PB line is attached to the plug on the front near the flow adjustment. In my first post I had the supply and the return backwards.

Between a lot of searching and I finally was able to get an old lap top back up that had a manual on it that showed the flow path it finally is working correctly. I have tried to attach the pages out of the manual but had no luck.

This shows the flow of the 870 type rockshaft. I am not one to just not try something because you need the dealer parts for it to work. There is not much info on this on forums.

Remove the large plug/cap on the front of your rock shaft and insert the "internal" plug to close off the port. Mine was installed on the port that was on the right side of the tractor.
