- Take off the focus indicator grip (rubber).
- Unscrew the retaining collars from the inside of the camera (don't lose the screws!)
- Pull the whole assembly out of the back
- Rack the focus collar all the way to the base of the helical (away from the copal opening)
- With the helical and collar pointed as if they're going into the back, orient the helical assembly so that the infinity collar is pointing to 12:30 or 1:00
- Install the retaining tabs like ears on the left and right. If you get one tooth, the other should snap into place. They have a top and bottom—if you're looking at the back, make sure that the side with the slight bevel on the tooth is facing up.
- Put the screws into the retaining tabs first
- Lower the whole assembly into the body
- Attach the screws —*don't over-tighten.
That should do it! Let me know if that helps. And hopefully this helps anyone else in the future to reassemble the 90 helical!
