TO-35 Power Steering

I have a 1957 Massey Ferguson TO-35 with a Davis front loader. I'm looking for a hydraulic steering unit for this tractor. The front loader support structure prevents some aftermarket solutions.
 
The most compact and simplest solution would be to find a factory power steering gear.

But, be sure there is a blank cover plate on the engine, just in front of the distributor, back
side of the timing gear area. If not, there is no place to mount the factory pump. A belt driven
automotive pump could be mounted, but might be tough with the loader in the way.

If you go this route, best to have the donor tractor there, or at least have the opportunity to
remove and document all the needed parts so nothing gets lost, damaged or left behind. Be a good
idea to replace all the seals before you install the gear.

Adding electric assist steering is also an option. It would probably be cheaper, but it is somewhat
bulky, requires cutting some sheet metal under the dash.

But using it on a working tractor is going to really stress the steering gear. All it does is
amplify the torque being applied to the input shaft. How the steering gear holds up will be a
gamble. They are not over built enough to handle much of that.
 
I've got a MF35 with a Davis loader and manual steering, and it's okay as long as I remember that I can't turn the wheel unless the tractor is rolling. Even rolling very slow will make a huge difference.
 
Yes, power steering will stress the steering components more. Muscle power with hydraulic assist will be more powerful then muscle power alone. If a tractor with a loader is not moving and the front wheels are in soft ground, muscle power may not be able to even turn the wheels. Add hydraulic assist and they will turn, but the same ground resistance is still there so there is more stress on the spindles, tie rods, etc.
