A fella dropped off a NAA for me to do some odds and ends work on but one the things he wants me to do is put power steering on it. How can this be done? I know very little about Fords. Thanks.

I found another site that sells them as well. The YT site won't let me post the link because they consider them a competitor, but if you remove all of the spaces in the line below and paste it into your browser it should work. The first one on that page says it is for all of the 4 cylinder models made from 1953-1964 including the NAA:

As WayneIA said, Roland Jackson makes a kit too. He doesn't list a price on his web site, but here's a link:

Thanks Sean. Will keep track of the YT power steering conversion.

What about those aftermarket systems like for the hundred series, won't those work on the NAA as well? They use a single cylinder down the left side and include linkage that goes under the nose of the tractor to connect the left and right spindles together and does away with the right side linkage. Our hosts here on YT list one for the NAA specifically, but they say it is currently out of stock:

I think the best way to add PS to an NAA is to find one off of a 600/800 or 4 cylinder 2000/4000. All will be a direct swap onto his tractor. It does require a bunch of parts so you probably want to buy a complete package and not try to buy everything piecemeal. Going rate for a complete system is in the $1K range plus install.
Yes, there have been posts about installing an electric PS unit off of a car onto an 8N. I personally am not impressed by them. To begin with you have to chop up your dash and hood so badly to graft the unit onto the tractor.
Worse though is they apply the power in the wrong location. Except for some later steering systems All the Ford PS systems apply the power assist IN FRONT OF the steering box. The electric add on applies it BEHIND the steering box.
The result is like having a 400 lb man ham handing the steering wheel and will cause early failure in all of the steering box componants.
A hydrostatic system like Royse added to his tractor is a good, viable option too but there isn't a "kit" for it so you'd pretty much need to design/build the system and source your own parts - all of which might cost the old gentleman more than a used OEM system would.

"I have heard of electric power steering out of a car being used on a tractor."

Yes, it's been many times. I haven't done it myself, but if you search

the archives I remember is being posted many time for the N series.

I have heard of electric power steering out of a car being used on a tractor. How does that work? This NAA is a tractor ride tractor owned by an older gentleman.

Some pics of the one I did. The valve unit in the first picture

required cutting the steering wheel shaft to install. The second

picture is mocking it up and building the brackets to hold it.

It came with a belt driven pump to feed it, now it's hooked into

my loader pump via an adjustable proportioning valve.

It only runs one cylinder to push/pull the steering drag link on one side.

Originally I made my own brackets, but later I replaced the drag
link and radius rods with ones off a later tractor, 641 I think, to
have places to mount the cylinder.

I believe this is a Char-Lynn unit, but I'm not positive.

Google Jackson power Steering. Work beautiful, Done three of them . But it is and expensive deal
