[Farmall] Farmal H Fluid pumping out of hole in hydraulic fill cap

[E. John Puckett]

It would help to know a little more, such as what kind of loader, is it 
stored outside, did you just buy it, or have you owned and used it for a 
while, etc.  The first thing that comes to mind is water contamination 
raising the fluid level, though that is not common on hydraulics.  The 
second thing that comes to mind is either low fluid level causing 
foaming, or the wrong fluid having been added that may also cause 
foaming, the old liftalls used non detergent motor oil, though Hytran 
could be used but motor oil needed to be flushed out first.  One other 
thing that comes to mind is that if it is a model 30 or 31 IH loader, 
you need more plumbing.  The H liftall does not hold enough fluid to 
operate them (M does, but not H), and there are return lines that go 
from the outer end of the cylinders to the fill cap of the hydraulic 
system so overflow can go into the top of the cylinder, and then be 
drawn back as needed.  Here is a link to a copy of the owners manual for 
the model 30 loader showing the needed additional plumbing if that is 
what is needed.  The plumbing for the model 31 is the same.
