I am rebuilding my PS Box and had some questions for the forum, please. This is a 1966 230SL, and the box has been leaking so I removed the assembly, removed the pitman arm and steering coupling, then began disassembling the unit itself. I had looked across the forum and tech manual for guidance as I began the task, and printed off some relevant posts/articles. I realized this evening that all of those pertained to manual steering. I have removed the cover at the pitman arm, removed the shaft that it attaches to and began to remove the assembly that the steering shaft attaches to. It appears that this assembly cannot be removed until the "valve assembly" is removed first because the outer diameter of the assembly won't clear the valve assembly. So I removed the bolts securing the cap where the inlet and outlet lines connect but the cap still seems to be pretty tightly seated. (See photo.)
I can see there is a gasket between this cap and the body of the box so it is clear it is removable but I am hesitant to pry it off until I checked with the forum. I certainly don't want to muscle something that might still be attached in some manner. At the opposite end of the body, there is a seat that a spring fits over (see that photo as well) but it doesn't have any visible means to grasp or loosen (to remove the valve assembly from that end).
I would very much appreciate some advice from others who have performed this task. Also, if there is a kit that I should get, that would be helpful as well. (I have a kit that I ordered but I think it may be for manual steering.)
Thanks very much,
Harry
