I broke down due to lift valve bottom seal failure when mowing. this is the o ring for power steering aux tube. I removed the valve cleaned and replaced o rings on shaft and all o rings for the (4) tubes connecting them to the correct locations and inspected double flair lines for damage and reinstalled and changed fluid and filter which was about due. startup and leaks streams out of same bottom seal. removed and inspected, no reason for leak, it almost seems like there is not enough squeeze on o ring seat. o rings are not pinched or broken have tried several times with same result. can anyone help my lawn is a field now.
