I am attempting to clean the shutter of a GIII QL17. I removed the rear lens cell and would like to remove the front cell as well. This is an issue I had before - when I attempt to remove the whole cell, only the front element retaining ring unscrews, leaving the rest of the front lens cell in.
Is there a simple way to remove the remaining lens elements? This camera looks as if somebody literally tried to oil the shutter - there is so much lubricant on the blades that just a simple flush won't do.
Thanks,
Jan |

The entire front lens cell is not easy to remove if the front lens element comes off. Canon suggests a special tool made from a piece of metal tube, it is described on the last page of the repair manual which can be downloaded from the repair manual section.
You can try to get to the notches on the bottom of the front cell with small screwdrivers, once the retainer ring of the front lens element is off there is a bit more room to reach them. |

Jan,
For the G-III, I use a pair of specially ground and bent heavy duty tweezers to reach the lower notches. I then grab the two legs of the tweezers with an adjustable "Crescent" wrench to turn the tweezers. Very un-conventional method, but it works well for me. I would love one of those special tools however. I've found these front cells can be REALLY tight and require some scary torque to remove.

Thanks, W & W!
I actually posted the querry just before leaving home and am now in the office. I will see what I can do when back at home. I don't recall seeing any notches in the remaining lens cell, but will check again.
Thanks again,
Jan |

I had this problem with a Hi-Matic 7sII recently. I resorted to carefully cutting a pair of notches with a file so I could remove the lens housing with a lens spanner. Once you've got the lens out you can clean up your notches to make sure that the threads are OK for the front element retaining ring to go back on. The notches are hidden by the retaining ring once you reassemble the whole cell (at least this was the case with the Minolta).
Good luck,
Wayne |

Normally I drill two tiny holes in the inside perimeter with a pin vise (not all the way through...just divots), use a pointed tip spanner and then fill them with flat black paint after I replace the central element. There are images of this on the rangefinderforum.com in the tech section. It comes out very easily that way.

Thanks again for all the help. The camera is already in perfect shape, with the shutter working as it should, with clean shutter blades and new seals.
I followed Will's above suggestion, slightly modified; took a little bit of brute force, but the lens cell came out.
Jon, I did indeed remember your method, but forgot where I saw it - now I know! By the way - sneaky hink2u outdid us both!
All the best,
Jan |
