Assuming your engine has the blank cover for a pump, mounting a pump would be the easy part.
If you have everything to rebuild your manual gear, you could keep that and add an assist cylinder and directional valve to the tie rod, think 60's Ford passenger cars that had a cylinder underneath.
Or find a donor tractor and convert everything to factory. That may cost more (depending on the deal you can find) but in the end would be a better way to go.

ooked at some pictures last night and looks like the whole power steering is done in front of radiator/with the pump,resvior ,and lines as you have mentioned...but that assy would be very hard to find and as you say the assist may be the only option...i still will have to repair the steering wheel box reguardless...thanks for your input

To add PS on the F40 you will have to replace everything inside grill and add pump.
If you can find a salvage tractor-F40 or early MF65 and know it is good then it's not
that big of job.The early 65's that has MHF will work not sure on the early MF50. Yes
it's completely different from a 35.

It was a good design. The F40 became the MF 50 in 1958. Same tractor.The early 50 PS should work on your tractor. I've never changed one using the 50 but have used the early MF65 PS.
I think the 65's use a straight cut gear on the end of the ps pump that meshes with the internal gear where both the 40 and 50 having the Z134 use a spiral cut gear. That gear will have to come off another 134 with ps. I put an early 65 ps unit onto a gas 50 and missed the bolster gear timing and steering is off in one direction. Also the 65's reservoir has to be remounted and won't fit inside the grill.
