I just replaced the hydraulic pump in my 340. It
is the 12 gpm tranny driven type. The tractor has
power steering and there has been a leak at the
expansion plug at the base. It wasn"t too bad with
the old pump, but got much worse with the new
pump. The plug look like it had come partially
out, so I gently persuaded it back into place. I
was running the tractor over the weekend and it
was running great and there no leakage at the
plug, only some minor leakage at the hydraulic
control block/valves. I was pretty happy and
figured I could live with that. Then, I noticed
some major leakage coming from the power steering.
It looks like it is coming from the top of the
column at the steering wheel. I am assuming that
it is the top seal. I am concerned that there is
too much flow to the steering unit. Any thoughts.
