and i'll even give up some of my tricks.
spray the degreaser/electrical contact cleaner into a shallow wide mouth glass jar. put the item(s) to be cleaned in the jar with cleaner. put on the lid and swish it around, let sit 5 to 10 minutes, remove and dry. rub off any residue that did not wash off, common with dried grease.
rub the shutter and aperture blades with extra fine powdered graphite paying special attention to their pivots.
Should I be able to take the "gear train" out of the shutter housing for cleaning?
Yes, it can be disassembled but it may not be necessary and it may be very difficult to reassemble.
I have never serviced one of these and this one is the first I've seen.
What I meant to ask was:
Can the delay unit or what ever it is called.. what's inside red line in photo below.. be removed from the shutter (from the front) as one unit to flush it. I would not like to flush while it is attached to the rest of the shutter.
(The shutter is now closed and on the camera, and when it was open quite some time ago I did not inspect it close enough to know now.)
Once again, I have only seen your pictures of this make of shutter. I did not know they existed before your post. From the responses very few readers if any others have.
In your original photos, #6 shows 5 screws, 2 on each end, and 1 outside edge center of the gear assembly. I cannot tell if they hold the top and bottom plates together or if they hold them to the shutter case as well as together. Remove the cocking ring assembly. The outermost screw at the right holds the assembly to the case. The left inner is either a screw or guide pin. If two screws remove both and lift out, if a screw and pin remove the screw and lift out.

I have been searching the net as I also have a problem with exactly the same shutter and lens when I found this thread.There seems to be very little info on these and as you guys seem to know what you are doing could you please explain something. My problem is that the front shutter plate( The black ring with the speeds and tempor written on it )is not fixed tight.It has about half a stop total side to side movement. This means that the focus stop moves with it resulting in an inability to get correct focus.Question is how do I tighten it.If I take the shutter assembly out of the camera body will I find screws at the back to do the job or will I have to dismantle the shutter from behind? Are there locating pins at the rear of the front plate ? Is this a common problem that someone else on here has had? Any tips and info much appreciated.Apologies for asking this on another members thread but as I said there is very little info and you all seem to have got this sorted
can you post a picture of yours?
Many shutters have a retaining ring behind the front lens element that hold the shutter plate and speed ring in place, it may be loose.
Thank you shutterfinger
I now need some courage to remove all those small parts and springs.
Comparing this shutter-inside to pictures of Prontors or Compurs etc., it seems relatively simple and straightforward, but I still don't understand it as well as i should.
Certo6 writes positively about the Tempor, while one person on the net has written scaringly negatively about it: Springs flying and thin parts difficult to assemble, so I dunno.. It's a pity there is so little information available. Hope my photos whill help a bit!
I'm not shure I fully understand your question.
I may send to you larger versions of the photos I linked from post #1, if you think that may help. Just PM me. The black (face-)plate is not screwed in place. It's simply held in place by the ring that you can see on photo #4. Maybe this ring is out of position on your camera?
Here is a better photo of that detail.
I did not take good photos of the removed faceplate and ring, but you can just about see it here.
The small tab on the faceplate you see at the edge of the photo goes into the opening you may see at the previous photo.
(Now, good night.)
Compur shutters use a spiral tension spring like a watch main spring. It is easy to release it when removing the delay gear assembly in Compur shutters and a pain to get tensioned correctly. Some Compur shutters have the delay assembly riveted together so there is no opening it.
I haven't worked on any Prontor shutters either so I can't comment about them. Open the delay gearing only as a last resort.
Thanks for all the help.The second photo has clinched it.At some point someone has stripped this down and lost the clamping rings. The groove is there but no rings.Given that I probably wont find another ring the only way round this that I can think of is a bit of a bodge.Two very very small blobs or epoxy tucked in to the ring groove.This will pin the front plate to the fixed front focus ring mount. Not something I want to do but it will make the camera usable again and is a lot better than leaving it in the cabinet. The silver focus ring will cover the repair. I will use no more epoxy than I think I can remove at a later date should I need to.Many many thanks for all your help again
