Rolleiflex 6008 Film Magazin(e) Repair

[ic-racer]

The Rolleiflex 6008 film magazines use friction from the backing paper over a roller to advance the frame counter. If there is any slippage, the counter mechanism won't advance and the film will wind farther than needed, causing increased space between the frames.

Here is a video of the problem. The counter gets hung up at #8. In this case that I caught on video, the film still advances frame by frame. But usually it gets caught up between the numbers. In that case the film keeps on advancing, rolling up the rest of the film to the take-up spool.

First picture: The red button latches need to be disassembled. There are 4 screws holding it together.

There is a metal piece (not shown but just beyond the green aorrow) that is glued in place by the take up spool. This needs to be removed.

Second picture: There are 4 screws holding the inner frame. In my case one screw was shorter than the other three.

The two little screws that hold the clear window on the back need to be removed. They go all the way through and hold the inner parts together.

The pressure plate is held together with two black slotted screws. The pressure plate is connected with a wire. Remove the screw that hold the wire to free the pressure plate.

Wiggle the whole assembly out. Watch for the little springs (green circle).

I un-soldered the wires from the contacts to get the wires back through the hole to allow further disassembly.

Disassembly is pretty tricky, maybe not for the first-timer.

The pins (green arrows) need to be pushed up and out of their respective slots in the backing plate (already removed here) and pulled outward. This releases the area (circled in green) where a little pin holds each arm to the backing plate.

The rails (circled in red) then slide out of two lips on the backing plate that hold the rails.

The 4 springs shown should be held in place and not fall out.

Another picture of how the two pieces come apart. The 'plunger' that goes over that shaft and its spring are already removed here and not shown.

 

[ic-racer]

Once apart, there will be a spring over the shaft in the middle (not shown) and a plastic 'plunger' which is shown. Also, there is a silver washer on the plastic plunger (not shown).

The circular plunger has teeth that grip the velcro and turn the counter wheel. When the back is opened, pressure is released on the plunger and the counter springs back to the start.

Initially I thought the slippage shown in the video was here, but there is no slippage here. When the back is closed, the plunger grips the velcro very tightly. Something is making the counter wheel hard to turn when it gets up to the 8th frame.

Be very careful of the contacts in blue. They are very fragile. They look solid but there are multiple little filaments that can easily be damaged.

 

[ic-racer]

To remove the counter wheel, there is an e-clip (yellow arrow) that needs to be removed.

At this point the spring of the counter is already unwound. It took me a while to figure out what holds the counter under spring tension. The plastic window opening on the outer shell fits up into the opening and stops the wheel spinning at the area of the purple line. As you can see the pin has already gone past that area and spun an additional revolution, totally unwinding the spring. This spring will need to be wound up before re-assembly.

Also note the correct position of the end of the spring, sticking through the window.

 

[ic-racer]

This is my counter wheel. Something was binding and caused the scratch. Binding of this wheel made the counter/roller hard to turn right at the #8 position. Thus leading to the issue shown in the video of the first post of this thread.

 

[ic-racer]

I couldn't find anything under the counter wheel, just the spring. So still a little mystery, but after careful re-assembly all works fine.

 

[ic-racer]

Re-assembly is the reverse except for the issue of how to tighten up the spring on the counter dial.

I inserted two cotton-wool sticks (with one end cut off) in the mechanism. This pressed the plunger onto the velcro and held the wheel in place.

I was then able to wind up the wheel one whole revolution past the "S" and it held in place.

Last picture shows a green dot where the pin on the counter wheel needs to be so that it will be caught by the window ledge when it is put back together.

 

[ic-racer]

With it back together, the window ledge (purple line) extends down into the opening and will stop the pin on the counter wheel (green dot) when the cotton-wool sticks are removed.

 

[ic-racer]

If everything went correctly, when the cotton-wool sticks are removed the counter wheel should spring back to show "S", but not totally unwind. There should be one-revolution of tension on the spring before it starts counting.

Excellent tutorial because understandable, clear and concise with informative pictures, thank you!

You can also see the high quality of materials and workmanship.

I'm doing less and less repairs lately and I'm glad to see you doing more, keep up the good work!

Thread title tweaked

 

[ic-racer]

I have seen it spelled "Magazin" and "Magasin" and "Magazine." Though I think they may be slang for "Wechselmagazin."

Point taken, and parentheses added accordingly.
(I based the original change on the first words of your first post).
And "Film" was added, to differentiate it from a thread about camera repair publications

Good job, someone else here will be very happy when the time comes. This is pretty rare stuff especially if it goes un-repaired.
Thanks for sharing!

I agree as a German native speaker

Just processed some film from this magazine and the spacing is correct now.
