Help taking apart nose gear strut

[Skymaster337B]

Herb, thanks for the reply. I have the manual, but that paragraph just isn't written well. My question is how to access that ring....where is the access hole in the upper strut? How to remove the lock ring if it's internal? Does the ring remain inside the upper strut after it is popped off?

I see the ring in the drawing but I don't have a clear vision of how to pop it off from the inside. Any more guidance is appreciated.

Thanks,

Rob
