Hasselblad back problem

[pekelnik]

I just put a Hasselblad kit together, and I seem to have a defective back.
I did not try to put a film in it yet, but I understand that even without film,
turning the crank clockwise should ultimately change the frame counter to
1 and stop. This doesn't happen and the crank turns indefinitely and the counter
never goes past 0.

Is this a known problem? I know people will tell me to take it to a tech, but I'd
prefer fixing it myself if this isn't extremely difficult and someone knows what
the problem might be.
Thanks!

Do you have a A12 or C12 back?

 

[pekelnik]

A12. I just fixed it Found a service manual PDF online, took it apart, there was one displaced spring. Works like a charm now!

Do you have a link for the manual? I might need it in a couple of days.

Fortunately the Dreaded Two Letter Troll is no longer here to give me grief about how it differs from his perfect world. My Bad!

Thanks, but what was misplaced was one of the springs in the mechanism itself. If you remove the right leather, you'll find three screws.
Unscrewing them you can take the right wall with the crank off and you get this:

One of the springs there was just sitting not connected so
I looked at the schematics and re-attached it to where it belongs.
