Power steering pump and rack overhaul?

Power steering pump and rack overhaul?
Hi!
My Iron Lady (1989 XJ-S V12 RHD) is losing quite a bit of ATF from the powersteering pump and the rack. So I plan on overhauling both.
The steering rack has loads of life in it yet, as it doesn't grind, nor is it juddery. It is nice and smooth but leaks on the left hand side. So I'll be overhauling it at the same time.
Has anyone done this job on both the servo as well as rack?
I've found part kits via SNG but before I order them: is the job managable for a quite skilled self-taught mechanic? I'm no newbie regarding repairs and co, but I also learn by doing. As I have a second PS-pump in my spares collection, I'm willing to risk it.
Any tips? Parts recommendations? Tool recommendations?
Cheers in advance!

After 14 years on various auto forums, Jaguar in particular, I've concluded that DIY steering rack overhauls usually don't work out too well....but let's wait to hear from others with direct experience.
As for the pump, well, it's probably just a matter of partial disassembly to replace leaking seals. That should be relatively easy
Do you have the shop manuals?

Hi Doug,
cheers. Well, I don't really need to replace the entire rack, basically just the bellow and seal on the left. So that should be easy enough. A full overhaul is probably just me doing it ALL or NOTHING
Regarding the manuals: yes, I've got the German workshop manual, but that oddly is so "confusing" when it comes to continutity. Pages missing, filed later, etc. As a "rough" guide it is fine...

Well, I have the pump in pieces... If you know what you're looking for, it is quite easy...
Everything visible is from the pump. ALL parts have been torn down and it is all in pieces. Just waiting for the new rubber seals etc. and will then seal it again... Though I might compare this one with my one still fitted (was my spare one) to see which one is in better condition... This one has done around 100.000 miles, where as mine only 78.000 miles.

Hey Warren,
I did not have to replace the shaft bushing, as mine was still within the tolerances.
If the shaft has shot, I'd recommend getting a recored pump internal. They cost about €30 on Rockauto. Waste of time even fuss ing around with that. Just need the rubber rings to seal the pump and you're off again...

I have the lockring and end cover off now. Pins are pulled, and the rests sticks in place. I suppose this is just oil sticking of flat parts ??
The ROM shows a different drive belt disc fixed with a central nut and as I read it I'm supposed to tap the axle and pump out from the drive side. This is not possible as I see it.
The good stuff is that your picture of all parts shows same axle/hub as I have and you have managed to disassemble it.
How did you proceed after getting the lockring and cover off ?

Below is the hole clearly visible on both pictures as is my different-from-ROM hub.
