<P class=MsoNormal>Ron,</P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I understand that cycling the cylinders “should” remove
air, but not sure it always does that well. </P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I would try breaking a hose at the cylinder, and pumping a
few gallons of oil through the hoses, 1 at a time. I would bleed the ‘up”
hoses with the lift down, and bleed the “down” hose with the lift up if you
have a way of holding the loader in the up position so that it does not fall
when you break the hoses and move the lever to the “down” position to flush
that line. The reason for that it to minimize the amount of oil on each side
of the cylinder ram when you bleed that side. </P>
<P class=MsoNormal>An alternative is to remove the pin from the lift cylinder
and disconnect it from the loader to extend it when you are bleeding the
“down” circuit.</P>
<P class=MsoNormal>I would have something to catch the oil you bleed so you
can refill your system after you bleed each hose. You do not want to run your
pump out of oil.</P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I agree that a faulty hose (kinked, crushed, internal
lining failure, object stuck in hose) could also cause problems. When you
bleed the hoses, if 1 bleeds fluid slower than the other, that would be an
indication of some hose issue. Replacing a few hoses may be a way to insure
that the hoses are not a problem. Some loaders have combination of hoses and
steel tubing – look for crimped or bent tubing.</P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Question – when you rebuilt the cylinders, was the inner
cylinder bore good all the way?? It is possible that the cylinder bore
streched in the center, where it allows oil to bypass the cylinder seal at mid
stroke, but seals fine on both ends. This is not a real likely thing, but it
is possible. </P>

<P class=MsoNormal><BR>It seems really unlikely there is still air in the
system after all the <BR>cycles it has done.<BR><BR>Is it possible to swap the
hoses where the two sides are tied together?<BR><BR>My guess is that there is
an internal fault in a hose on the left side. <BR>If there is, swapping the
hoses would move the problem to the other <BR>cylinder.<BR><BR>You could also
swap the hoses for the bucket and the lift at the valve <BR>and see if the
problem remains in the lift or if it moves to the bucket. <BR>That would
confirm the valve function.<BR><BR>Both of these should be easier than
swapping the cylinders which would <BR>be a last resort option to prove it is
in the cylinder itself.<BR><BR>Just some off the top of my head ideas to
isolate the problem.<BR><BR>My tractor blew the main pressure line the other
day and pumped the tank <BR>dry before I knew it. Replaced hose and refilled.
Two cycles of each <BR>cylinder purged all the air and it once again was
running smoothly.<BR><BR>Hopefully someone else has some other
ideas.<BR><BR>Stuart<BR><BR>On 4/13/23 00:53, rdhaskell@juno.com
