ILEX Universal SHUTTER does not close

[Vlad1970]

Dear friends. I have a camera with an Iles Universal lens. Until recently, it worked, but yesterday when I turned on the T shutter speed, something clicked and the shutter stopped working. I disassembled it, washed it with alcohol, checked all the springs, and found out that one spring was not strong enough to close the bolt until the end. If you put a more powerful spring, then there is no force to open it. All shutter blades move without friction, easily. Perhaps someone can tell where the problem is? And how to solve it.

There are some parts under the top plate. The shutter looks very dry. While Ilex say they were designed to run dry they run smoother and quieter with light lubrication.

It’s dirty. Dirty and dry. Did you disassemble to clean? If not, it sometimes takes several flushes to get a shutter clean enough.
