I have a 350u with manual steering and front PTO pump (for loader) off the front of the crank (not the distributor gear style or belly style).
I bought the power steering parts from a 350u that had the belly style pump. Came from a junkyard and not sure it was working or not other than it did steer the tractor to move it around with no engine (bad block).
Anything I should do to test the power unit before I start? Anything I should replace as far as seals etc (I will use all new hoses for sure)? I was going to try testing it with air, then turn the steering shaft and see that the motor moves one way, then steer the other and see the motor move the other.
Not sure what pump to use:
I read other similar posts and found a 1965 ford mustang Eaton pump that i can buy working for $30. I can fab a bracket, i have a plasma cutter. Might just take off the generator and put the Eaton pump there to start with since the generator is not really keeping the battery charged anyway.
I saw a chrysler eaton pump with 6 volt delco generator combination for $100, but wasn't sure the eaton steering pump would be right though. It is two units with one pulley, that would bolt right up to the current generator bracket, i would probably have to use the guts from my 12V generator, and I don't know if they would be the same.
The other option would be to tee off the big pump, but as that one is used for loader and backhoe I am apprehensive about it. Also I would have to add some kind of valving for that I think, as I understand it the pressure regulation was down in the belly; and the Ford Eaton pump has it in there, and of course my big pump does not have that; relying on the control valve banks.
I looked at the power steering on my Super-M and see that there is an added front pump with a belt and it's own pulley. I thought maybe there was a way to add an extra pulley to my 350 and then leave the generator pulley separate.
I should mention that i use the thing to dig in tight places like my creekbed, and filling my 57 chevy 4 yard dump truck (yeah i still use it to haul stuff). it is never used for field duty, have other tractors for that.

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
