Delphi 600 steering conversion issues with a '64.
I have replaced the oringinal power steering on y '64 with a Delphi 600 power steering conversion kit available from Ecklers. Naturally the process was not quite as painless as hoped for, but overall not too awful. Of course the fitting for the high pressure didn't match the '64 pump ('male' ends on both the pump and the line) and the Hotchkiss sway bar had to relocated slightly to avoid interferance with the pitman arm and the underside of the steering box, but the result was worth the effort. Steering is much quicker (3 1/4 turns lock to lock), precise and responsive.
I used the original drag link with an "steering replacement control valve conversion" that replaces the control valve with an iron sleeve that connects tho the pitman arm to avoid replacing the drag link with a manual steering one.
So what is the 'issue'? The 'box' was 'centered' to be certain that the amount of travel was the same left to right and the front end was aligned, but get the correct toe-in the passenger tie rod had to be lenghtened over two inches longer than the driver's side one. fortunately there is plenty of adjustment and no shortage of threads in the tie rod, tie rod end and idler arm to accomplish this, however I am concerned about a potrntial change in geometry left to right as the wheels move up and down because of this difference in length. Seems to me that ideally both tie rods should end-up about the same length. I have nothiced some 'bump steer' over large dips that was not there before the conversion. (not severe, but noticable)
Does anyone know if there is a difference between manual and power steering pitman arms and where the it attaches to the drag link? Should I have changed to a manual steering drag link and pitman arm so that both tie rods would be more equal in length? I know that I am not the only one to have done this 'conversion'.
