[Farmall] Farmall 340 Loader Question

Larry:
Just taking a stab in the dark with a couple of suggestions....

First, check that when the filter was installed none of the gaskets twisted 
and try to see if all fittings remain airtight.
When the dealer put in a new relief valve in my 574, the system did not 
work properly when I got it back.  It would operate, but everything would 
jerk and the pump whined.  After I took the tractor back to them they found 
that when they had installed the hydraulic filter, an O-ring had gotten out 
of palce and it was drawing part air and part oil.  Obviously, you have it 
up to the "Full" mark woth oil, so (just taking a wild guess) the only 
other thing I can think of that might help would be to drive the tractor in 
a small ditch or something so that the side with the filter is lower than 
the other side, and the front is lower than the rear.  I am thinking that 
possibly this would raise the oil level in the lines enough to allow the 
system to properly reprime and rid itself of air.

Good luck!
