I came across a large hydraulic cylinder a couple years ago, $75. most recently came across a NEW 20hp liquid cooled kawasaki motor $450. (business auction) Absolute steal. I admit hydraulics are pretty confusing for me, especially crunching the numbers. Anybody want to throw some expected cycle times and other helpful info my way. I figured a 28gpm pump from northern tool and the 20hp motor would be pretty strong, but may not be enough to power this cylinder.
the only identification on the cylinder reads. RCA-60021-03031-307081
the bore seems to measure 6.5 inch bore X 4.5 inch rod
the length is about 40 inches long, doesn't include the rod end.
bottom port measured inside the threads 1 5/8 in. might be a 1 3/4 in. npt ?
top port measured 1 3/8 in. (inside threads). might be a 1 1/2 in. npt ?
I would be using a cylinder stop to limit the stroke to about 26 inches, because I cut wood to 24 inches. I'll get a couple pics up of the cylinder, because the 40" measurement includes the bottom (pin hole) attachment. Just a guess, but I think it is closer to a 36 inch stroke.
