jip Posted May 20, 2017 Share #1 Posted May 20, 2017 (edited) Advertisement (gone after registration) Hello, I got a Macro-Elmarit-R 1:2,8/60mm cheap locally from 'the bay' equivalent. The thing is it's aperture stops no longer click, according to the guy it happend when he tried to take it apart. He didn't get further than the bayonet mount but when he tried to put it together again he saw one of the bayonet screws would no longer fit in because there is a small metal 'ball/pin' inside of it. Now my idea is that this little ball/pin makes the aperture ring click normally. Would there be an easy way to repair this? It's a ROM version of the lens by the way (if this makes a difference) See attached photos. Edited May 20, 2017 by jip Quote Link to post Share on other sites More sharing options...
Advertisement Posted May 20, 2017 Posted May 20, 2017 Hi jip, Take a look here Macro-Elmarit-R 1:2,8/60mm Click stops GONE. I'm sure you'll find what you were looking for!
jip Posted May 20, 2017 Author Share #2 Posted May 20, 2017 P.S. I do have all the bayonet screws luckily the guy kept them! Quote Link to post Share on other sites More sharing options...
TomB_tx Posted May 20, 2017 Share #3 Posted May 20, 2017 (edited) Aperture click stops work by a spring loaded ball being pushed into machined grooves in the face of the aperture ring. Normally the ball sits on top of a tiny coiled spring, all pushed into a small drilled hole under the area of the aperture ring where the grooves are located. It's very easy for the ball to come out and roll away during dis-assembly. Looks like in your case it rolled into one of the mount screw holes - hopefully not jammed too tightly. Maybe a strong magnet could pull it out. A bigger problem would be if the spring that was under the ball jumped out and got lost. The balls in different sizes are available from Micro Tools - the springs are a problem. Use a spot of grease on the ball to stick it in place when assembling.

jip Posted May 20, 2017 Author Share #4 Posted May 20, 2017 Let's hope so!! I'll probably send it to Will van Manen for a CLA anyway, and then he can 'repair' it or well, assemble it... haha Quote Link to post Share on other sites More sharing options...
MarkP Posted May 21, 2017 Share #5 Posted May 21, 2017 (edited) Consider it a bonus! It's already primed for video use ;-) Edited May 21, 2017 by MarkP 1 Quote Link to post Share on other sites More sharing options...
pgk Posted May 21, 2017 Share #6 Posted May 21, 2017 You may find the Leitax website useful - the disassembly instructions here show the mechanism and ball bearing which creates the 'clicks' on the Leica 60mm ROM lens: http://leitax.com/conversion/leica/Elmarit-60-ROM/index.html Quote Link to post Share on other sites More sharing options...

jip Posted May 22, 2017 Author Share #8 Posted May 22, 2017 Thanks for all the useful information and the URL to the Leitax website which helped a lot! So everything inside the lens looks fine except that little ball that got lodged inside one of the bayonet screw holes... I cannot get it out by shaking, magnet or suction of air... so it looks like I'll have to order a new ball... Unless anyone has any tips of getting the ball out of the bayonet ring.

pgk Posted May 22, 2017 Share #9 Posted May 22, 2017 Unless anyone has any tips of getting the ball out of the bayonet ring. You could try a very small dab of glue on a pin, push the pin/glue onto the ball bearing and see if you can get it to set sufficiently to allow you to haul the bearing out - just a thought which might just do it. It is an option which won't cause harm if you are careful anyway. Quote Link to post Share on other sites More sharing options...
gbealnz Posted May 22, 2017 Share #10 Posted May 22, 2017 Can you get better access to the ball if you remove completely the bayonet mount? Gary Quote Link to post Share on other sites More sharing options...

jip Posted May 22, 2017 Author Share #15 Posted May 22, 2017 Will van Maanen has got the balls, pun intended And the springs! I was on the phone with him today 1 Quote Link to post Share on other sites More sharing options...
Steve McGarrett Posted May 23, 2017 Share #16 Posted May 23, 2017 Jip, give a look to Leitax site, there are step-by-step tutorials for removing bayonet in each lens, you can see immediately in the pictures where the small bearing ball has to be placed. It's very easy to fix it. Hope this helps. Quote Link to post Share on other sites More sharing options...

It can use a CLA anyway so I'm sending it out for CLA for about 120 euro. Then it can last the rest of my life Quote Link to post Share on other sites More sharing options...
