[AT] RE: Ih 504

[Andy Glines]

I don't know anything about the 504 specifically.  Generically speaking, I 
would first check the pressure that the pump developes.  If you look around, 
I'm sure that you will find a plugged port that you can put pressure gauge 
into.  Someone here probably knows how much pressure the system on a 504 is 
supposed to make.  Your local case/new holland dealer should be able to tell 
you as well.  It may be as simple as adjusting the relief valve on the hyd 
system.
