Hasselblad 500 ELM Jamming mid-shutter fire

  1. I recently picked up a Hasselblad 500ELM in pretty nice shape, though it's jammed. I disassembled the camera a few times, and finally figured out the likely issue. For whatever reason, when you fire the camera, it jams mid-firing sequence, it goes far enough for the mirror to flip up, but stops just short of the lens' shutter fully closing before the exposure, and before the rear doors open. Does anyone know how to fix this issue? At one point I had removed the internals from the camera's shell, but couldn't find a way to remove the large gear that couples from the motor drive to the film advance gear.

    Anyone have any advice? A repair manual would be incredibly helpful, I did find a 555ELD repair manual, and a 500CM manual, but both cameras have enough differences from the 500ELM that it was only partially helpful. Any help would be greatly appreciated.
  2. Not sure if the shutter release mechanism is the same but with a 500C C/M 503, etc. the front plate has to be removed to free that gear up. Then you put four complete clockwise rotations into the gear/spring and reinstall the front plate. Luckily there is an accommodation in the inner mechanism (hole in a gear) to allow you to install a paper clip to lock the wound up spring as you reassemble it. This is covered in the 503 manual (thanks Orsetto).
  3. This happen to me once, and I change the batteries and no problems since.
