Rolleicord I Compur Shutter full disassembling?

[evgenys]

Hello,

I decided to return to the life my old Rolleicord I camera (okay, it's not the LF stuff, but here people know what Compur shutters are), but after testing speeds of its shutter I've understood that I have to make a CLA.
I partially disassembled the shutter, but after removing the speeds gear set I noticed that other part of the shutter (with release lever etc.) is very dirty too. So I need to fully disassemble the shutter to clean everything.
Unfortunately I couldn't find the manuals of the full disasembling of this shutter. I see there are several small screws and hair-like springs, but I don't know what to unscrew first.

Any help will be appreciated!

BTW, I use Isopropyl Alcohol to clean the dirt inside the shutter. Is it correct choice, or I should use lighter fluid instead?

Hi, and welcome.

You really need a service manual for that shutter, so you dis-assemble it and re-assemble it in the correct order. That's very important.

You also need to lubricate the mechanism after it's back together.
There are various greases and oils used at specific locations, as described in the manual.

All lubricants are used in very small amounts.
If you use too much it will get on the shutter blades and screw up the faster speeds, or get on the diaphragm and delay its closing.

The shutter blades and aperture blades should be completely clean and dry.

Thanks for the info, but the google couldn't help me to find the manual how to disassemble the Compur C00 shutter. Thus I posted the question here.

Thanks, but this is later manual. It doesn't cover before WWII shutters.
