QL17 … the final frontier

After I figured out the shutter release and cleaned up the gears, I still had a problem with the aperture … so part III.

Tools

  • Screw driver
  • Soldering iron
  • Spanner wrench
  • Dental spatula
  • Ronsonol
  • Lots of Q-tips

The first thing to do is to remove the two leatherette pieces from the front of the camera. Have patience and you will be rewarded with singular pieces. Start from the outer edges and work your way in towards the lens.

Remove top cover. Then remove four screws holding the lens assembly, and pull it off.

Flip it over.

Remove the two screws that secure the baffle.

Pull off light baffle.

Unsolder the wires. Note that the longer one is on the left.

Unscrew rear lens group first. Then you can unscrew the retaining ring that is hidden underneath. This holds the lens/shutter assembly to this plate.

Pull off lens

There are three rings here.

Dark one sets the shutter.

Spacer in between

Silver bottom one trips the shutter release (in this image it was moved off the pin).

Remove them.

OK, now down to the nitty gritty (whatever that means).

The aperture blades are gummed up. The red arrow points to the arm that is moved to open the aperture. The green arrow points to a (pathetic) spring arm that pulls it into an open position.

I washed out this area with Ronsonol … then exercised the aperture … then did it again. Use Q-tips to clean off the blades. Continue the cycle.

Let it dry

Continue the clean, wipe cycle until it flows like butter, or at least until the little spring can pull its weight.

The best way of cleaning the blades is to take the whole thing apart and individually clean everything … I am not that ambitious.

… I would like to thank a couple of Japanese bloggers that posted their experience with taking this camera apart, the photo’s helped (but the translation failed).
