SOme had engine driven pumps under the governor, others (later) had transmission driven pumps. (both live hydraulics) The power steering valving is in between
the hitch control valve and the reservoir. the Regulator Safety valve. Jim

it has a cam driven pump;i put another one on it that Ii know is good,but doesn't work on this tractor.i put it back on my other340 and it works fine.i thought maybe they may have both cam driven and transmission driven.

It is located between the hitch control valve (right rear of seat) and the reservoir. Jim

What is the tractor doing? Is the engine grunting and the pump whining as if it's trying to pump against something, or does it seem like nothing is happening at all?

If nothing seems to be happening, it is most likely due to the pump not picking up prime.

One more item. If the screen in the reservoir is plugged, it will not prime. A nasty device to get at, Lid off, but either make one or buy a
new one (nasty price), Draining the reservoir (right bottom corner of seat area) you could see it with a fiber scope. Jim

I've had a 340 since 1995. Mine will sometimes lose prime. I crack the big hose where it ties into the
steel line. It let's the air escape. Try it and good luck

Mine will lose prime if hy-tran level gets low, as I have a couple seals that leak. When it loses prime I drive it to somewhere I can get the front end lower, like a ditch or septic system mound. That works good for me.
