First post here. I hope someone can help.

I have a B&H 471 self threading projector.

It has worked fine for the last two days, then I couldn't thread it.

The black rubber wheel wasn't turning.

I pressed down the back of the threading wheel lever and shone some light inside. I could see some crumpled film. I removed it. There was always this clicking sound which I figured was the broken pieces of film. (The sound is gone now and the films I had watched were a bit slow)

Now the black rubber wheel turns but the film only goes in a short way, I hear that clicking sound again, and when I take the film out it's bent and crumpled.

I figure there's more crumpled film in there somewhere but I can't see it.

How can I take the gear mechanism apart to look?
