340U hydraulic pump conversion

PaulW_NJ · Oct 23, 2008

Does anyone have any experience converting from the engine driven 9 gpm hydraulic pump, to the internal transmission driven 12 or 17 gpm pump?

I have a 340U with a loader, and am setting up remotes to operate a log splitter. The extra gpm"s would be handy.

I did mine. Your serial # needs to have the
Z suffix (maybe) this would indicate that the
pickup tube from the rear area to the filter
cavity is in place. My pump, mounting plate,
& filter came off of a 504. The man at the
junkyard knew they are identical. I got the
new pump drive gear from IH, it's supposed to
enable getting the correct lash if I remember
right. I also used the valve set from the 504,
the bracket was easy to modify.
