Hello There, Thank you everyone for all your time and effort. I am having a leak that after washing the unit, and filling the hydraulic tank to level, it leaks under the pintle arm seals that the steering levers connect to; I just purchased the manual hoping that it might help, but they have this repair with the whole pump removed from the machine. Could this be done easily, since there is no much room in there? Also, would just the seal and o-ring be the issue? or could it be a worn shaft or over pressure? Any info would be appreciated. thank you
