I'm working on a Ferguson TO35. I'm currently having a issue
with the hydraulic system and the 3pt. the owner complained
of the three point being slow to raise with a load on it. a
pressure check showed the pump was only making 1000-
12oo psi. the pump was worn out beyond specs so I replaced
the cam, cam blocks, and all new O-rings where required. I
now have 2000psi which is what is spec'd for that hydraulic
system. the problem I am having is that now when I start the
tractor regardless of the position of the draft or position control
the 3pt raises to the fully raised position and will not lower
while the tractor is running. I also made all of the other
necessary control linkage adjustments as per the service
manual. what could be the cause of this problem? I am
absolutely stumped.
any help is greatly appreciated. thanks.
