Massey Ferguson Hydraulics Issue

I have a MF 20C industrial. I added rear remote Hydraulic ports by puting a Hydraulic Selector, isolator assembly in place of the standpipe cover cap. After I got everthing bolted back together I had No 3 point lifting or remote flow, so I took the Hydraulic Selector, isolator assembly off and put the original cover cap back on and now I still do not have any lift. The Trans/Hydraulic fluid is new and full. I have removed and replaced the rubber O-Rings, tripple checked standpipe placement and still nothing. Everything was working prior to the initial selector valve instalation.

Thanks for any Ideas,

Did you install new MF O rings and nylon back up washers on both ends of the stand pipe?

I did put new rubber O-Rings but not nylon washers, that could be the issue. Does the nylon washer go to the inside of the pipe or to the tip of the pipe.
Thanks so much for the info,
Jake
 
The nylon back up washers go on the inside of the stand pipe. The O rings are to the presssure side.
