Take a look at the [b:654c4848f0]POWR-TROL VALVE HOUSING[/b:654c4848f0] diagram below.
![a168526.jpg" width="650"](http://"http://photos.yesterdaystractors.com/gallery/uptest/a168526.jpg" width="650" /)
Note the plug (Key) 9 and the oil coupling (Key 25).
Take a look at the photo below of the plug, sometimes referred to as a "dummy plug".
![a168527.jpg" width="650"](http://"http://photos.yesterdaystractors.com/gallery/uptest/a168527.jpg" width="650" /)
Note that the plug has a solid, closed end.
The plugs are installed in the Powr-Trol housing when a remote cylinder is not in use.

Take a look at the photo below of the oil coupling.
![a168528.jpg" width="650"](http://"http://photos.yesterdaystractors.com/gallery/uptest/a168528.jpg" width="650" /)
Note that the oil coupling has an open end.
Take a look at the photo below of how the oil flows through the oil coupling.
![a168529.jpg" width="650"](http://"http://photos.yesterdaystractors.com/gallery/uptest/a168529.jpg" width="650" /)
If the remote cylinder has one hydraulic hose for both supply and return, then connect the hydraulic hose to the bottom oil coupling.
![a168530.jpg" width="650"](http://"http://photos.yesterdaystractors.com/gallery/uptest/a168530.jpg" width="650" /)
If the remote cylinder has two hydraulic hoses, one for supply and one for return, then connect the supply hose to the bottom oil coupling and the return hose to the top oil coupling.
Hope this helps.

I have both plugs with open ends in both back ports. With the return on top and supply on bottom from the right side ports. when I push the lever forward the cylinder goes out but when I pull it back it doesn't do anything , I can push it in a little by hand thou. but both plug with the hole from the check valve closer to the edge then the ones in the picture

Those are parts for both the upper and lower check valves.
Take a look at the diagram below.

Note that the upper check valve is connected to the upper oil coupling.
The upper oil coupling is connected to the hydraulic hose return from the remote cylinder.

No, one of our Model 70 Diesels is "plumbed" from the side and works just fine.
