Help with Fuji GF670, decoupled RF mechanism by mistake

[AlanY]

I was fiddling with the GF670 idly when I heard a light snap that sounded like something got detached (not that something broke, I think). Now the lens doesn't return to infinity. Tension stops it at 3m or so, and I don't want to force it.

It's hard to see what's happening in there, but I can vaguely see that the two levers/hooks affixed to the front of the lens that connects to the rest of the RF mechanism are now detached. (Circled in the attached photos.) And I can't close the camera up.

Does anyone have experience with this problem? Thanks.

This may give you some ideas

The video definitely helps. Thanks! I hope I can fix it myself.

I am trying to get a tool that turns the pictured screw. What is it called?

 

[AlanY]

A spanner, I think...

Practice with it a bit; that tool can cause more damage than you can imagine if you try to use it casually...

Kino, thanks. I tried this tool and it sort of worked the first time, but it wasn't quite pointy enough to grab the screw tightly. I thought about sharpening the tips somehow. Maybe that's what I'll do.

Is there a dedicated tool for this kind of screw? Or is it non-standard and exclusive to Fuji?

I am sure Fuji trained repair people had a custom spanner for just that screw, but the odds of finding and purchasing it are slim to none.

Snap/retaining ring pliers might work better for you: https://www.zoro.com/channellock-re...MIzuCAmdOH4wIVFo_ICh3ggQnGEAQYAyABEgJGRPD_BwE

They can be found in any automotive parts or tool store.

Thank you Kino. These definitely look promising.

Thanks Huss. This is the same tool that Kino suggested and that I used the first time. The tips weren't pointy enough to grab the screw well. And the many points and degrees of movement on this wrench made it unstable. Although I did manage to get the screws off eventually, I ended up scratching them a lot, as seen in the photo above, and couldn't screw them back on very tightly.

I am going to try one of the retaining ring pliers Kino suggested and will report my findings for future would-be GF670 repairers... In the video above Mike Eno also made his own spanner.
