Hay I got a white 2-105 that having some
hydraulic issues it will work fine to it
gets hot then will kick the PTO off
whenever you use the steering or hit the
brakes or remotes which indicates low
pressure but I just installed a brand new
pump not reman a new one so not sure why
it's doing this I've replaced all the
rubber lines so there's no hose that's
clapsed and it is circulating through the
cooler and updated the filter system to a
high output spin on so there's no chance
of it sucking in air. I don't have gauges
or anything to really test the pressure
iv adjusted the compensator valve back
and forth but makes no difference it
seems like. I had to pressure control
valve assembly apart and cleaned before
installing the new pump and didn't see
anything obvious that was outta place I
did attempt to rebuild remote outlets
because they were leaking like a civ but
they still leak as bad as they did when
before I did it so could that possibly be
a a reason? It seems to me that there's
an internal leak somewhere that's making
the fluid overheat really fast anyone got
any ideas?
 
you are definately going to either take to someone that has the guages and fittings or buy the guage and fittings along with the service manual. Their too complicated to just guess at it or to do a trial and error. If every thing is set correct they work very nice.
 
The pressure reducing valve is the problem of pto kicking out when hitting the brakes. The pressure is just too low, like below 190 psi. You need to shim up the spring for this valve in the valve below the hydraulic pump.
