Polaroid 405 back rollers - need help for assembly

<p>Hi, I have 405 film back. It's rollers are clean, but theyre really stiff.

<p>If I try to pull tab to get picture out of holder, the tab will tear. The spring that pushes the other roller

downwards seems to be really stiff.

<br>

<p>How stiff it should be? I can hardly push business card between the rollers, but often the card will bend.

<br>

<p>Also I like to know whether there are some detailed pictures of 405 back's roller assembly available at the

internet.

<br>

<p>Thanks for advance,

<p>Jukka

<p>Here are some photographs. I hope that it makes my question easier to understand :)

down.<br>

<br>

<p>This illustrates scenario when 'print' is pulled between the rollers. Now the spring is really stiff and its

hard to pull even card that is used at the picture:

<br>

<p>Finally the picture that shows the spring and roller axle when I have pushed small screwdriwer between the

rollers as an spacer. That illustrates how flexible the spring could be. But should it be?<br>

Thanks,

<p>Still wondering with same issue. Does anyone have any photographs that illustrates how the rollers should be?</p>

<p>Google doesn't help much :(</p>

<p>Another question about the back rollers of the 405 back<br>

The U shaped springs on the left and right side rusty. Is it possible to pull out these springs to clean them.</p>
