Mike ,Does it look like the center of the outer rubber seal is supposed to be in a fixed position on the shaft?
Thanks,
Mike
The one in my photo is from a series 5 I parted many years ago. I see differences in how the two are made. Is yours one of the MG valves?Photos of a taken apart newer valve below.

Mike ,
The seal did push over the round tab on the shaft and set in a slot much like hydraulic seals in the master cylinders. It appears that the part I would refer to as the bellows pointed down into the cylinder. If you look close you can see under the round tab the remains of the seal that separated from the rest of the seal. As the rubber dried out and became brittle it looks like the seal comes apart. There is another rubber seal that sets against the yoke that holds things in place.
While I've not experienced the issue, some have said that pipe can separate from the casting.
