I'm attempting to build a splitter for a home for troubled kids I'm a volunteer at... I thought we'd have TWO good splitters by now, but so far it's a wash.Splitter one...Cost: $100, used. Rebuilt storage damaged 5 HP Briggs, installed trailer axle under it.single stage pump, no detent on valve body.3 inch cylinder, 18 inch stroke. Works well on smaller wood but just won't do the big stuff over 10 inches without "nibbling" at it. I have about $200 in it total. Splitter two: Obtained free, was mounted on an old '55 chevy truck. has cylinder from some backhoe or dozer on it, yellow..looks like it is a 3.5 by 20 inch stroke. Weighs a TON.
Pump was operated off the PTO on the transmission by a driveshaft with U joints. I don't know the RPM..DOes anyone here?
Pump is a cessna. I had to take it apart to flip the backplate so it would turn the correct direction on the VAC I was driving it with.There were some scores in the housing and end wear plates. Dual control valves, one running a crane cylinder at one point. Problem: slow operation, and nowhere near enough pressure to split anything. I am thinking the PTO is not running fast enough..The Eaton Pumps I saw on the net were rated at 4000 PSI at 3600 RPM. I'm only running it at 540 on the VAC, and it IS slowing it down some when it hits the log, so it is building some pressure. So.. option one, replace the ram on splitter one with a 4 by 24 ram from Northern, and possibly install a 2 stage pump.... Option two.. different pump and possibly a pump and motor for the bigger splitter.
What would you do? Suggestions?
I'l post the pics of the PTO pump on my webshots page in a bit..
