[Vwdiesel] OT: Case 580B CK hydraulic question

[James Hansen]

Sounds like the return side of the valve body is open to the swing left
circuit.  When it pressures up the return as the dipper, stick or bucket
cylinders dead end, the flow from the valve stack PRV (which goes to the
general return, or should...) is pushing the swing left.  End of the spool
on the left circuit may have come loose if it's the kind of valve spool I'm
thinking of, or there's a fubar oring on that end of the spool.
Is this a Case/ David Brown made in England or newer than that?

Do the  swing cylinders operate normally otherwise? In other words, do
they swing  the boom all the way left and right, and do they stop the
boom when you  take your feet off the pedals? If the boom is off the
ground, can you get  out and manually swing it from side to side?





Swing works, it will push left if working hard resistance to the  right.  
Maybe 
it creeps left just a tad.  Considering the force to push it  left, I'm sur
e it could 
be pushed manually but I don't feel quite that strong lately.   ;-)
