Olympus 35RD vertical focus alignment

[Cortexturizer]

Hi guys, tried to find info on this but no luck. Hopefully one of you will know how to approach this.

So basically I've seen this on the 35SP:

"35SP (and some other Oly models) has a tiny lens inside the rangefinder with what looks like gear teeth around it. Turning this gear either way will adjust up-down of the rangefinder."

So, would this gear that needs turning the one that the arrow points to at the screenshot that I attached to this message?

Thanks

So, for anyone else in need for this potentially, here's the 35 DC repair manual which is basically super similar - http://olympus.dementix.org/Hardware/PDFs/35DC_service.pdf

and the page from it which I screenshot and attached to this message which shows that I was right in presuming which screw is responsible for vertical alignment.

Well, I opened up my 35RD but the mirror seems to be glued to a small panel keeping it in position. There is no screw to turn.
What am I missing?

See the attached pic please.

Anyone?

I can't tell: is there a hole in the back of that mirror base? Like, where a screw may have been? If there's a hole, is there possibly a recessed grub screw, for adjustment?

That's definitely the right mirror for vertical adjust (on the 45 degree mirror furthest from the eyepiece). I am not familiar with this specific camera, but, a common mount-adjust design would have the mirror attached to a tightly angled metal spring leaf, and that leaf attached to the mirror base. Then the adjust screw (passing through a hole in the leaf where it mounts to the pedestal) would act on the leaf, where the mirror is attached, to vary the angle.

I'm thinking that someone had found the mirror (mirror-leaf?) loose, and glued it into place... but I'm unsure. (And, I am, after all, only a semi-accomplished repair hobbyist.)

OR, maybe the attachment glue is supposed to be flexible enough to serve as the "hinge," if indeed there is a screw hole.

Nah, the screw is under the blob of glue seen in my last pic that I attached. I removed that blob and obtained access to the screw, made the adjustment and now everything is perfect!

Good show! It's always satisfying to DIY, and get it right. Much better than DIY, and get it wrong.
