Have removed the pump assembly and there is red PAS fluid within the adaptor (EAC3968) and on its under-surface by its ?drain hole.
In order to proceed further it seems necessary to remove the driving dog (EAC7081) from the pump shaft, within the confines of the aforementioned adaptor.
The Service Manual illustrates Special Tool 18G 1445 but this doesn't look right for this operation.
Question - how is the driving dog fixed to the shaft, eg taper fit, keyed. I could make a "puller" but need to know what I am up against!!

The hoses are the usual suspects though, sometimes only leaking on full lock when the pressure rises, it sprays fluid all over the place - I know from experience!

I don't know for the 6-cyl cars, but for the V12, it was a generic size.Need some help please. I'm looking for a replacement "O" ring for the high pressure hose on my power steering, Part No. CAC35892. This is NLA but I guess I something generic would suffice if I knew the size. Any thoughts greatly appreciated.
If you still have the original, measure it with a micrometer, taking care not to squash it. It will almost certainly be a British standard (if imperial fitting) or ISO (metric) size.
If not, a rule of thumb that really does well is an o-ring sized at exact fit on the inside diameter, and 10% larger than the gap to the outside diameter or width of housing, whichever is smaller (usually the width is far larger than the difference inside to outside diameter, and provides the necessary space for the squished ring to expand into).
I got excellent service from http://www.polymax.co.uk when I wanted a mixture of sizes for my pressure washer, lawnmower carburettor, and yes, V12 power steering, though you'll probably find the size you want in a box of assorted generic O-rings from Halfords or Maplin.
Note that if you fit the wrong size, the only likely disaster is a severe leak under high pressure, and you can test for that in the garage - just try to turn the steering wheel hard from lock to lock with the engine running. If it don't leak, you should be fine. O-rings are very forgiving.
