Has anyone replaced the light seals on an A-series Canon? Or lubricated the mirror dampening flywheel to deal with shutter squeak or shutter timing problems?
I picked up a black Canon AV-1 with an f/2.0 50mm, like the one on the left here (it was a limited edition for the '82 World Cup, so came complete with the World Cup lens cap) .
It was only £15 and was meant to be broken - the shutter was stuck up, but it is in good nick I quickly got it going by fitting a new battery and leaving it on top of my computer for a while (the shutter was stuck up, and it seems the warmth melted the goo and let the shutter come down again, have heard other reports of this happening).
The light seals are completely perished, so I've ordered a kit to fit replacements, but I'm worried that the perished light seals have got into the mechanism, so it might need cleaning out inside or lubricating.
Since I got the shutter going again it's been fine though, and there is no squeak/cough, so I'm not convinced it needs doing. I don't really want to pay to have it done so would probably have a go myself, but I'm wondering if I should just leave it unless I have problems with exposures (until I load a film I won't know this, of course) or with the shutter again?
