Hi guys I'm new to this form so not quite sure if posting in the
right section. I have a 1973 Massey Ferguson 50 industrial
tractor. It's equipped with a back hoe. The tractor starts right
up. But wether on or off the steering spins freely. I have
already changed the power steering pump which is ran by the
timing gears and no change. I have disassembled the steering
valve and inspected it the plunger showed no signs of any
scaring so I cleaned and lubricated it and assembled
everything back together. Still no change. I opened the
hydraulic lines that go to the steering cylinders and no
pressure in either lines. I'm thinking the only thing left is the
obital valve which is really pricey. So I want to be sure before I
go ahead and replace it. Any input will be greatly appreciated!
I'm unfamiliar with this hydrostatic steering setup. If anyone
can explain how exactly this setup works if appropriate it as
well!! Thanks!
