Seems I screwed up again, it was the "rod" that I measured, and
incorrectly called the piston. I looked in a catalog at some cylinders
of the same orientation and looked at the rod size compared to the
bore, and it is very different. I think Im dealing with a 4" bore and
the other is probably 5 or 6" bore. All Im trying to do is find out
what GPM the pump should be. I tried finding the valves on Parkers site
and got errors. I tried searching for the mfg. company and nothing
turned up. Can you guys tell me how to figure GPM with the info I have?
I couldnt find anything telling me the force required to bend 1"
rebar. I have emailed some companys with no answers yet.
Thanks guys, sorry to be such a pain
