could the pressure from block blow good seal in a good pump..or does the pressure come from the pump...if something was bad in
the block.....some one straighten me out please......dewy
 
Block? Which block, engine block or hydraulic block? I doubt the engine block could create that kind of base pressure to blow the hydraulic pump seal. If the relief valve in the hydraulic block is not functioning, or the control levers are not adjusted correctly, well maybe.

Basic hydraulics... pump provides the flow, something else causes pressure. If there is constant pressure, there is something wrong in the system. If there is too much pressure, the relief valve is not doing it's job of relieving or controlling the pressure. Most likely the pump shaft is worn and hydraulic fluid has leaked by the seal.
 
tryed 5 different pumps all with new seals... the last installed with speedy sleeve..still gets by seal..i guess i will try diff. hy.
block......aggrevating.....dewy

Is the system pressurized all the time? If it is, there is definitely something wrong. Do you have a Fast Hitch, or just the Touch Control? With TC, when you move one of the levers, it should only pressurize while the arms are moving. Same for the FH... once you release the control lever to center, pressure should drop off. I can't imagine the pump seal leaking unless it's under pressure, or at least leak very, very little.
