ChrisSpeaker Posted March 28, 2015 Share Posted March 28, 2015 <p>Hello everyone.</p> <p>I just got done selling a lens with a copal 3 shutter on the auction site. Buyer got it and complained that the shutter does not work! That part is another story but it must have suffered impact damage during transit.<br> Does anyone know off hand what can go wrong from impact damage? The aperture and shutter preview all work perfect, however when you try to cock the shutter it starts making the normal sound about half way through the cycle that it normal would at start. The red flag comes up but does go back in. The shutter trip level will not trip the shutter at all? This is true regardless of the speed setting.<br> Thanks in advance for any advice anyone can provide.<br> Chris</p> Link to comment Share on other sites More sharing options...
BrianS1664879711 Posted March 28, 2015 Share Posted March 28, 2015 That sounds similar to a Copal 3 on a lens I bought a long time ago. On mine it was some debris inside the shutter that may have dislodged in shipping and was jamming the shutter on release. Once cleared it started working normally ...

drew bedo Posted March 31, 2015 Share Posted March 31, 2015 <p>I bring all my shutter work to Mike Hakime at "Professional Camera Repair" in Houston. http://professionalcamerarepair.com/ <br> Another , and perhaps better known, shop would be S.K. Grimes. http://www.skgrimes.com/</p> Link to comment Share on other sites More sharing options...
don_gillette1 Posted August 26, 2015 Share Posted August 26, 2015 <p>If I remember correctly first remove front element then there is a brass ring that has to come off After removing ring you should be able to remove front plate. Then you will see the cam plate you will see pins sticking through those slots. You can remove cam plate But remember all those pins have to be aligned back in the slots. If you are going to clean shutter I recommend also removing rear element. The copal is a fairly good shutter except they were made of mostly brass that can wear. Now to clean it I usually used my ultra sonic cleaner with solvent. Make sure it is dried before re oiling. Take a pin just put the least amount of clock oil at each pivot hole. Don't use any other type of oil. There are different ways to clean a shutter but a full cla is the best. If you have any questions let me know. I know this sounds complicated but after doing a few it becomes easy, the next best thing is find a camera repairman, but know it will cost.</p> Link to comment Share on other sites More sharing options...
bob_salomon Posted August 26, 2015 Share Posted August 26, 2015 Might cost at a repair shop but would cost even more if he does it wrong. Link to comment Share on other sites More sharing options...
