Hello community,

I recently picked up Nikon F2A, but light meter had problems and needle was jumping around, I decided to fix this and disassembled the prism to clean it, suspecting the old contacts were dirty and the parts were not making good electrical connection. I succeeded in this and my light meter measures correctly now and it is working when I use stopped-down metering.

The problem I am facing now is that the AI peg that connects to the lens to get the aperture number has lost its springiness and doesn't return to its location, see attached pictures. Now, this was working fine before I disassembled the prism, so I suspect there must be some special way of assembly required to get the "springiness" to it I suspect the gear that turns it is under tension, but I tried everything I thought of, and internet resources on this topic were not helpful.

Do you guys have any idea how can I fix this? It's sad because otherwise I have a perfectly working Nikon f2 :sad:
