the 2nd to last looks like the spring ring is displaced?

I have checked those springs Pat and they are sitting OK. I went round them again though and tried to push them in further but still sitting in the same place. I'm wondering if it was the angle of the photo that made it looked displaced?.
PatM:
Julie, you obviously know what you are doing, i have no doubt! As you say, the photo may have been viewed incorrectly by me- it was the 'springs' in the seals i was referring to- one seemed like it was trying to 'climb off' the seal.
Did you find anything that may have made the forks jam down?
I did my 400/4 seals ages ago due to the usual weeps/pits. Exactly the same as you- off the bike and tear-down.
I was alarmed at your engine/piston/head photos! and amazed it still ran!
Nurse Julie:
Yes, it's those springs I have checked Pat. It's strange as if you look at the pic of the seals that came out, they look like they are sitting a bit scew wiff as well.
No, didn't find a cause for jamming down, it only happened a couple of times. I couldn't really measure accurately the amount of oil that drained out but it may have been a little on the low side. Anyway, it didn't do any harm stripping and cleaning and changing the seals, at least I know they are done.
Nurse Julie:
Aaaarrrrh, Paranoia is setting in. Just checked them again and they won't seat anywhere other than where they are, so they can stay there. Paranoia moment over ;D ;D ;D
Thanks very much to the forum member that gave me the seals FOC.....you know who you are.

I have been watching this thread and i am impressed with the work you are doing Julie, and here comes the concern, you have just done your forks and i have looked at all the pictures and i see you have re-assembled in exact reverse of dis-assembly, i rebuilt my 350f forks this year and they had never been off the bike, the difference is your seals appear upside down, this not only exposes the coiled ring to atmosphere and the possibility of rusting out but the chance of oil bypass and out of the top of the seal, i have replaced a lot of fork seals over many years and never seen them this way up, so unless this is a trick of the light or you have special seals, you need to replace the seals the right way up.
