Hey all,
Went to cut hay with my white 1370 2wd (same as oliver 1365 from what I read) today and about 5 min in when I went to make a hard right turn the power steering cut out completely.
-With tractor running the power steering almost wants to push to the right on it's own, on solid ground if you steer to the right it'll slowly keep going on it's own all the way to the steering lock. You can hold the wheel straight but cannot get the tractor to steer left at all.
-With tractor off you can turn left/right with some effort, seems to be the same either direction, to either steering lock.
-Level on reservoir above engine was good
-Did change transmission oil last week along with hyd filter, but from what I'm seeing that's a completely separate system, and the remote hydraulics are still working properly.
-I do have the service manual but I'm not really understanding. What exactly is sensing steering input so pump knows what to output to the steering cylinder?
EDIT:
-after more reading of the service manual I figured out the steering input gets sensed in the control box at the front of the cylinder. definitely seems to be the issue, the shaft moves freely inside the control valve. when you steer right it keeps pushing as previously described, when you steer left you can see the cylinder actually try to push right until it hits the pressure relief. if you release pressure to neutral and then try to steer left again a few times, you can sometimes get it to turn very slightly. light tapping on the control valve with a hammer while applying pressure at the wheel seems to cause some strange behavior in the steering.
-pressure relief valve seemed good, took it out and cleaned with no change.
now just wondering how do you get into the control valve to clean it, as it looks like the cylinder is no longer made and can't be replaced?
also found a blurb on another site saying there should be a set screw or locking collar to adjust if the tractor only wants to steer one direction. don't see anything about this in the service manual and I'm not spotting it on the cylinder.
Thanks!
