Canon 7 question

[Roastedinwhat]

Hi guys, I recently got a Canon 7 as my third camera.
When I first got it, there was some problem with RF, which I got fixed from the seller-adjacent camera repair shop.
But when I went there to get my camera back, the winding lever felt a bit fiddley.
Not that there is any problem with the camera it works just okay, but it kept bugging me. And the repairman just flat out told me he doesn't know what I was talking about.
Somebody on r/analogcommunity told me that I should try to tighten the wind lever screw, but that didn't work because the screw won't turn no matter what.
Could this be because somebody put plastic glue in the wind lever screw?

Is the wind lever loose? Like move up and down? Too much play in it?

The top screw has two holes in it for a Spanner. The wind lever has a ready position, it can be moved out to make easier to wind. You push it back in when not using, or in the case. You can move the lever a small way without the cover screw moving with it- so there is some play.

Hi, thank you for the reply
the problem is that the lever is kind of loose and it moves vertically and horizontally (but not that much?)
when I shake the camera slightly, the lever moves horizontally & vertically which made me think there is some gap between the lever and the bushing

You have come to the right place...

See page 5. The winder will have some play in it, and there is a flat spring as well. Take a look, then judge if the diagram explains what you are feeling.

I'll check back tomorrow- time for bed.

Wow thanks
It seems that nothing major is wrong with my camera, though, since you mentioned that it is supposed to have some gaps.
I was kind of annoyed that the winding lever was limp and moves a bit

sounds to me like your repairman forgot to put the flat spring back between the top screw and the advance lever.

If you feel comfortable taking the top cover piece off the lever, you can see what is in there with the PDF brian uploaded, it does sound like something might be missing if you say that the top piece with the spanner holes is on tight

Yeah I kind of felt that when I got the camera back
but when I asked him about the limpness of the wind lever, he flat-out told me that he didn't know what I was talking about
Should I use it if there seems to be no problem? Because I never heard that the flat spring is crucial to the camera functioning

I wanted to do that, but the lever screw with two small holes on top won't come off at all
It is just stuck there so I think I have go with what I have now

Do you have a lens vacuum pads? The smallest one can loosen/tigthen the advance lever

Do you state this from personal experience or because of the picture on the BH site?
I would expect a spanner to be able to exert a lot more torque.
@Roastedinwhat for such small two-hole screw caps I don't even bother to take out my spanner; small tweezers, the kind used to pull shards from your hand, will do; some have square ends, no good unless modified; some have pointed ends : better.
Another method I've used on occasion is to attach a suitable metal lever to the screw head with two-sided adhesive, not the thin one, but the thick kind, strong adhesive, used a.o. to affix mirrors on walls. Clean well both parts before gluing. Remove the adhesive with either acetone or white spirit followed by alcohol.

I do have those kind of tweezers, but for some reason the screw is stuck rock hard
I suspect that one of the previous owners lost that bushing and just used plastic glue to stick it in there.
I think so because it wont budge no matter what I do

Personal experience on my Canon 7 as I've been able to loosen/tighten my advance lever with it.

OP, is there any signs of glue residue on the lever?

Not really, but it is really stuck
I don't know how to explain this but I tried to physically use my bodyweight to push it, but only ended up slightly bending my tweezer

Not taken the top off of mine for a while, that screw isn't reverse-threaded is it?

i dont think there are any functional issues if that spring is missing, just what you are experiencing, also the pinhead lever screw should be tight but not that tight that a reasonable amount of force doesnt get it to move. I suspect the repairman cranked down tight on screw to minimize the slop to compensate partially for missing flat spring. Putting too much force on the screw to remove can shear the head off from the stem of the screw then you would have some functional problems, namely your wind lever not staying on camera

 

[Sonnar Brian]

Probably overtightened or cross-threaded. The latter- can be worse than glue. I've had some "what the hell happened" when taking lenses apart and putting them back together. Like the thread was malformed, and just screwing back in caused it to cross-thread. And never come apart again.

I should probably leave it as it is since leolab mentioned that it won't affect the camera's functionality.
Also, are camera repair shops usually not that friendly to people with less expensive cameras? Because if I had gotten an explanation about the limp rewind lever, I wouldn't have minded it that much since it would not affect the camera's function. But he was rather dismissive of my question.

 

[Sonnar Brian]

Given his behavior- I suspect he knew exactly what the problem was and did not want to deal with it again.
