How to remove PS box

Hi all,

The power steering on my /6 71 Scamp has been leaking from the steering box for some time now, and having just replaced the dash and put some torque on the steering shaft, I think I finally killed the steering shaft seal. It mostly leaks around the steering shaft, with a little bit leaking at the pitman arm seal. I decided to take the box out and replace both seals.

I had a helluva time removing the pitman arm from the center link - took about 50 whacks with a 2 lb hammer (didn't have much leverage under there). Got the dowel pin out on the steering shaft, removed 2 of the 3 chassis bolts... So now I've got 1 chassis bolt left and before I do that, I had a couple questions.

1) How do I separate the steering box from the column? Haynes guide is all I have and it doesn't say to remove the column. Do I need to loosen the column and pull it towards the driver seat? It seems like I would need to...

2) Good technique for supporting the box while I'm unbolting the PS box (and then also bolting it back in)? A jack?

3) Haynes guide says to mark the pitman arm on the output shaft of the box - I don't think the steering shaft can be misoriented, right? It can only go on there one way, it seems, with the dowel.

4) Any gotchas that I might be missing? I understand that removing the pitman arm seal might've been easier if I'd blown it out with it still connected to the pump, but I decided that removing the arm was going to be easier on a bench. Hopefully not a regrettable course of action.

Thanks in advance for any assistance,

John
