RRLund - other Oliver guys - 1800 PS question

Co-worker's 1800 blew a power steering seal, so he says.
Supposedly the one in the steering column as he got a bath.
I haven't seen the tractor.

Now he can't lift the loader to move/tow it?
I don't know a thing about these tractors, but that sounds odd.
Can you tell me how that system works?
 
Oh boy,now you're on questionable ground. The early ones had shaft steering with power assist,the later ones were hydrostatic. If it's hydrostatic,you should only have oil to the lines when you turn the wheel,so the loader should work as long as you don't try to turn it if it's a line from the hydramotor to the cylinder. If it's down along the floorboard from the priority valve to the hydramotor,you'd probably loose most of the pressure.

Anybody else,feel free to chime in here.
 
Randy: There are 4 lines on the hydramotor. In = pressure, out= low pressure and return from hydraulic cooler and right & left turn. If he blew the pressure line the oil will drain the system in a few seconds. Best thing to do is open the door on the hood and look.
 
"A" series was shaft steering wasn't it? If that's what that one is,it'd be a whole nuther thing wouldn't it? I think,like you said,it would still drain the system wouldn't it? Or did those use a belt driven separate pump? I never had an A series.
 
That's kind of a double seal in the top of the hydramotor. I've had them leak,but that's all they do is leak. They're at the bottom of the column and there's a bearing at the top that the oil would have to get past to come out. Not saying it couldn't happen,but it might be a first. I'd almost have to think it would have been a hose that blew oil up around the column.
