Here is what I have,Full hydro steering from PSC with rear steer on rocks,I have the P pump feeding a 5 port orbital and using the competition rear control valve and it all returns to a remote res. with the extra fitting for the rearsteer return line so there are no tees.Here is my issue,I have blown the seal out between the pump and can 3 times now.The first time we chaulked it up to me fucking up the can when I pulled it off my old motor and mounted it on the new(went from chevy to ford when I built the new rig).The pump and res. were the only used parts I had on the new set up and they only had 2 runs on them from last season.So I put a new pump on and made a couple minor plumbing changes to help get air out of the system,now with this setup my res. had just the single return port so there was a tee for the rear.I got it together,run it behind the house for about 20 minutes just to flex the suspen. and try it out and the steering seemed ok,not right but did work.If I tried the rear I was getting some back feeding into the steering wheel.I went to pull up to the house and the seal blew out again on the pump.I called PSC and decided my res. which was bought last year,had the baffle in the top was restricting the venting and building pressure so I bought a new res.with the extra port so I could get rid of the tee and got some more orings so I could just fix the pump myself .At this time I installed a different cooler with a fan and moved the res. even higher.I got it working on sat. and seemed to have the air out(just a couple tiny bubbles with the engine running).I started it this morning and with out me touching the steering wheel, the tires turned to the right,I have been having an Issue with this while I was bleeding it, without the tierods hooked up and turning the steering wheel,if I turned the wheel one way and let go of the wheel it will keep going until the ram stops it when it reaches the opposite side.Anyways I drove the buggy around the yard for about 10 minutes doing a couple figure 8s and the seal blew again.Here are a couple of pics,I am taking a guess that I might have a bad orbital.I am getting pissed that my buddy with his $500 junkyard tractor steering parts can go wheeling and I have missed 2 wheeling trips because of my $2500 steering setup.
