4430 oil leak at steering arm

[edkaczor]

Have a 4430 that is dumping oil out of the steering motor (above front axle) along the steering shaft... all lines are good it's definitely coming from there as soon as tractor starts... dropped the 4 bolt cover and replaced seal and o ring .. started tractor and didn't leak for 20 seconds then started pouring again... thinking and internal leak but I don't believe there is pressure to the steering motor unless you turn the wheel?? Any input or ideas ? Thanks in advance

Did you happen to take the side screens off and then the covers that go over the hyd pump, they side out flat and look? Just maybe something above the steering motor.

Yes took all that apart.. all seems fine there

My guess is if new spindle seal is holding then an end cap on the piston is leaking. Checking end cap o-rings requires removing a side frame. https://partscatalog.deere.com/jdrc/sidebyside/equipment/8957/referrer/navigation/pgId/136512
