I am building up a new service truck and mounting a full hydraulic Liftmoore 6K crane on it. The truck is an '06 International 4300 with Allison auto and a Muncie PTO which had been used for propane delivery. My research is showing it to be a 7-900 RPM output which without a speed increaser, won't direct drive a gear pump fast enough. I had been looking at building a gas powered hydraulic sled unit but it will take up a lot of room in my bed. I do have a John Deere 23cm 9 GPM radial piston pump from a cotton stripper salvage job and am wondering if it could be used in and open center system for the crane and outriggers. I would mount the pump under the bed and run a jack shaft to it with an overhead reservoir as it had on the stripper. It would never be able to go to standby but they can handle constant operation. Ford used piston pumps on their smaller farm tractors in open flow. Volume would be reduced as it wouldn't be turning at normal engine speed but it would probably be fairly close to my 6 GPM need. My I&T manual for the tractors that run this pump showed a flowmeter rating of 5.5 GPM at 1000 RPM. Anyone ever tried this or seen it done? Any input is greatly appreciated before I jump off into and unknown build!
