Prontor-S mystery

[Muggins]

I'm trying to sort out a Prontor-S shutter that I managed to spill lighter fluid into (don't ask!), with the usual results caused by dissolved grease spreading everywhere. Very frustrating as before I removed it to clean the lens up it was working nicely.

Having dismantled it all the way bar removing the self-timer escapement(and spent an age trying to get the main spring back on - note to self, don't ever remove one again!), I now find that I've got 2 speeds - B works, and 1/300 looks OKish, but the rest from 1 second to 1/100th are much the same.

Can anyone suggest what I've got wrong? I've been getting advice from Hans Kerensky but he has gone quiet on me (hope he's OK), and I've even gone to the length of buying another shutter form ebay to compare - this looked brand new, I'm sure it's never been on a camera, and I just can't see any difference between how the escapement on that is set and the one on my original shutter.

Thanks!

Adrian

Here's the factory service manual. If you don't have it, it might help.

Thanks, Chris. Hans has reappeared, BTW.

OK, I'll own up. In the end I dropped in the escapement from a new (really, never been on a camera, never had a lens in it) shutter from ebay. Now works pretty much perfectly.

For tidiness and curiosity's sake I dropped the old escapement into the new shutter. Now it gives B on all speeds. Something very odd in that escapement!

btw I'm still Ok but also have other things to do which request my attention like repairing a Rollei 35 at the moment 🙂
This to some extend limits my ability to quickly react to the many repair questions I do receive so please be patient with me.

That's quite alright, Hans - I am hugely appreciative of the time you find! There's a far happier looking photo in your inbox from me than the previous... err... many!
(does repairing a Rollei 35 count as a small job, as the camera is so small?).

Depends entirely on the size of your fingers 😉😉

Having seen Chris Sherlock's videos, I'm amazed he works with Retinas - I moan about my stubby fingers, but his are much chunkier - yet still he works miracles on Kodak's finest!
