I,ve installed a power steering (internal spool activated ) cylinder assy. on my Fordson Major Diesel , re-using the original left spindle steering arm. System works well and has lots of power assist. However ,, I find the steering would benefit from less steering wheel revolutions . Keep in mind the total number of steering wheel revolutions remains un-changed from the original non-power steering set up. I have done a bit of research in my parts manual , noting that the power assist steering spindle arm is a different part number( EIADKN-3133C) from the non-power steering spindle arm(EIADKN3133B) ( Left side ) . My question is ::: Is it possible the distance,, center to center,, of holes where drag link ball stud and center of splined area of arm where it fits onto top of spindle is shorter (or less distance), for the power steering arm assembly as compared to the standard steering arm assy. If so , that would account for as well as cure my seemingly excess revolutions of the steering wheel when making sharp turns.
