I re-hosed it completely this past spring for the customer i ended up buying it from. After i bought it, with a blown up engine I put a kit [seals, wear plate] in the pump. One o-ring was damaged but the gears and housing looked good, even the wear plate looked good. No difference in performance though. After using it a couple days, it doesn't foam the oil anymore. I suppose that could have been from it sitting for a while and completely apart. No foam now but still jumps same as before. Interesting thing i noticed about this pump is there is no actual shaft seal. only plate seals. The splined input shaft is open to the hydro end housing with one small spring and ball in one port. I think this is normal since this pump could never have been taken off before. But what is also means is that the pump can "suck" some from the hydro. Air is easier to draw then oil. I think I'm going to hook up my flow meter and pressure gauge and see what happens. funny thing is performance doesnt change between engine speed or hot/cold, always the same. Thanks again</p></blockquote><p></p>
