Canonet 28... lens barrel dismantle & lubrication..

[goldfinga888]

Hi,
As a result of something that occured to my Canonet 28 (see thread: http://www.rangefinderforum.com/forums/showthread.php?t=52108)

I've been thinking about cleaning and lubricating the focus ring movement, and I want to do this myself.

The only info/advice I've found tells me these are among the worst cameras to work on!

I'm up for the challenge!


Anyone with diagrams, experience, comments about the parts, what to watch out for, etc???


Thanks!

If it don't need it, don't mess with it. Just use a little contact cement and put the lens cone back on.

hhmmm... I know what you mean but the focus movement is very stiff.. don't know how long it'll be until it actually gets stuck!

The worst that could happen is I'll have a lot of parts XD

Take good notes and digital pics as you go. I don't know of a manual for tearing down the 28 lens barrel.

You will have to remove the leatherette and remove the lens plate assembly. The focus helicals are reached from the rear.

Thanks greyhoundman.

Pics and notes are a given! (I've already made a detailed description of 'taking off the top cover and bottom cover, and tools I've used/made for the process - without causing damage!). I've been very (possibly 'over') careful, that when I 'undo' a screw or 'take off/out' a piece, I immediately do the reverse to check (and understand) what I'm doing! (and pics of course!).

- perhaps this might be 'time wasting' to some, but I'm in no rush, and in the end, if my 'picture sequences can be of use to anyone else then great!
