  • Remote Hyd. modifcations for my 8naa
  • I modified my 8naa hydraulic system so I could use my front end loader and 3 point hitch at the same time going with the instructions by Paul Schultz. I did the conversion according to his instructions, now the front end loader works but the 3 point hitch does not. Is there any way to get a hold of Paul or someone that could
    help me. Any information would be greatly appreciated

  • When I first hooked it up and started the tractor the levers for the front end loader shook and hyd. system squealed with tractor at a idle. A friend said the return line was not big enough, so I hooked up another return line and run it in the fill cap and now the front end loader works but the 3 point hitch does not. Any suggestions

  • Are you sure you used an open center valve as opposed to one that s setup for power beyond?

  • This is an easy one. The OUT from your remote valve must return to your modified accessory plate, as that is the source for 3 point hyd pressure.. When you dump the remote valve OUT back to the sump, there will be no source for hyd pressure to the 3 point.

  • There is one out line from the remote going to the accessary plate and one to the sump.As I stated before that there was a pressure build up and that's the reason for second return. Also I have a gear pump if that makes any difference

  • If you have two "returns" you have a valve with power beyond. The test port goes to the IN port on the valve, the "tank" port on the valve goes to the filler and the PB line goes to the accessory plate.

  • As TOH said, we need to know what valve you are using and which ports connect to where, because if it has more than IN, OUT, OUT to cyl#1 and OUT to cyl#2, then it isn't exactly as Paul did it.
