Compur Electronic 3 shutter - what could go wrong?

[Pere Casals]

what modern substitute should be used instead.

I use this one for the internals of old Compur shutters, with total success:

It is a thin layer dry teflon lubricant, it has a solvent that evaporates leaving a layer of polarized teflon particles. Make the mechanism work just after application (while solvent still there) to expel dirt.

I've lubricated with that 3 old Synchro Compur shutters, some 4 years ago. Checked with a shutter tester, right now they all perform as they should.

Instead, I tried the same with two Seiko shutters with less luck, they improved buy still they don't work fine.

Thanks, I will get some. Do you have to dismantle parts or do you apply as-is?

I disassembled the 1st one, 2nd and 3rd were simply lubricated from the speed lever notch.

I had a Compur electronic #3 on my Symmar 300mm. For battery, I found a 4.5 volt on ebay with correct dimensions. Do not know how long it lasted, as I sold the lens.
