'fixed' hyd valve on 35

now no output?!

One of the two levers under the
front of the seat on my TO35 was stuck.
Bought owners manual, took off valve
body, freed up valve with some WD40.
Then stuck vertical feed tube back down
into pump housing, and bolted back on valve body. Now 3PH doesn't lift; additionally
I get no flow out of the two hose attachment points, one atop each of the two spools.
Pulled off the valve body and I AM getting
flow up the vertical tube (sure doesn't take
long to figure that out). I am stumped at
the moment - anybody know what's going on here.
Near as I can tell, I am getting flow up the
tube, the flow should branch at the T in the
valve body and feed both spools. I think I am
getting no pressure to the downstream
side of any of the valves (I can take the hose connection plugs right off). I
didn't measure pressure at the vertical
tube, but judging by how quickly it sprayed all
over, assume I am at least getting enough
to drive fluid thru the valve bodies.

Anybody know what they're doing here?

Got it fixed. Looks like I had put the parts together wrong. Under the big bolt heads at the rear of the spools the order should be 1] bolt head (has a tube in it) 2] spring, 3] check ball, and 4] a rod with sort of an arrow on one end of it. The rod goes with the arrow facing the
bolt head, and the rod goes a ways into the valve body. I had left out the check ball, in fact putting it in the outlet fitting. I was following the way in which the spool for the
loader was set up (this is a two spool valve body) and did same thing on the 3PH side, screwing up the 3PH. So, looks like former owner was playing around and also explains why he couldn't get the loader working.

Real moral of the story is need to
buy the MF service manual, not just the owners manual.
