Straight from the back burner, I have been tinkering with this 520H. I bought an orbital steering valve from 19richie66 and decides to modify the 520 to power steering.
I seen a thread a while ago were someone added steering to a 518. Figured that would be a nice side project if I came across a reasonably priced steering valve.
I wanted to keep it looking the same and tucked in the column. It was a little tricky with a mix of face seal and jic piping. Picked up some face seal fitting from MMC and silver soldered to the steel pipe.
For now it is on ice, next will be the front axle mod to accept the steering cylinder.
Absolutely don't need a 520H with power steering but I like to build things and keeps me out of the Mrs. cross-hairs.
Used the c120 and old deck belt to test run.
