Telemetric Posted February 9 Share #1 Posted February 9 (edited) Advertisement (gone after registration) Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! As it could not be otherwise (I’ve had issues with all my Leicas, unfortunately), after just two weeks of use, the frame selector lever has fallen off. Luckily, I noticed it, and it fell onto a soft surface. I reinstalled it and tightened the screw by hand, but of course, I am not feeling entirely confident about it. I’m reluctant to send it to Leica for this because I’ll end up waiting six months just for them to apply a bit of thread locker. The question is: do you know if thread locker is used here, and if so, what brand and type does Leica use? I found in internet this but I don’t know if is correct: If the frame selector lever on your Leica M11-P has come loose, you can secure it yourself using a suitable thread locker to prevent it from loosening again. Leica likely uses a mild or medium-strength thread locker, as stronger variants could make future disassembly difficult. Steps to Fix It Properly: 1. Remove the Screw - Carefully unscrew the lever completely. 2. Clean the Threads - Use isopropyl alcohol or a degreaser to clean both the screw and the hole to ensure proper adhesion. 3. Apply Thread Locker - Use a medium-strength (blue) thread locker, such as Loctite 243 or Loctite 222 (low strength, safer if you want to remove it later). Avoid high-strength (red) versions, as they may make future disassembly difficult. 4. Reinstall and Tighten - Screw the lever back in and tighten it firmly but without overtightening. 5. Let It Cure - Allow the thread locker to set for at least 24 hours before using the camera extensively. Since Leica service times can be long, this should be a quick and effective fix to avoid sending it in. So, if is correct, medium or mild? Thanks in advance.

Telemetric Posted February 9 Author Share #8 Posted February 9 Just now, Knorp said: My bottle (10ml) of 222 is dark red. That’s what I suspented. I think the blue one is the medium. The screw is very tiny and I think the mild (222) is more appropiated. I am very dissapointed with Leica quality. I had problems with the 3 Leicas I have. Unbelievable. Never happened before with my analog Nikons, digital Nikons and digital Sony. Not even a problem. With Leica…. M6 : Lightmeter M10-P: Rangefinder and memory slot And now this with the M11-P. I know is a silly think but if I pay a lot of money for a camera I don’t want this kind of silly problems. Well, will see. Link to post Share on other sites More sharing options...

My purple (low strength), blue (medium strength), red (high strength), and green (wicking) all come in red bottles. On the other hand my medium loctite stick (looks like chap stick) has a blue cap. For something like that lever I'd use low strength. If I didn't have any low strength on hand I'd use a drop of nail polish. 1 Link to post Share on other sites More sharing options...

Is what I supposed, the mild and the medium can be confused due its color similarity. I will use the mild one, 222. Thanks a lot! Link to post Share on other sites More sharing options...
Telemetric Posted February 10 Author Share #15 Posted February 10 This is what Loctite answered me. So the winner is the 222 (purple, not red!) For the small screw that holds the lever next to the lens on the Leica M11-P, the best choice would be Loctite 222, and here’s why: 1. Loctite 222 (purple - low strength) - Designed for small screws (diameter below M6). - Allows easy disassembly with hand tools without damaging the threads. - Prevents loosening due to vibrations but without making it too permanent. 2. Loctite 243 (blue - medium strength) - Stronger and requires more force to remove, which can be an issue for such a small screw. - Might be excessive for a camera application, where occasional disassembly may be needed. - Could require heat to loosen, which is not ideal for a delicate part like the Leica lever. Use Loctite 222, as it’s strong enough to prevent the screw from loosening but not so strong that it causes issues if you ever need to remove it. 1 Link to post Share on other sites More sharing options...

MinRas Posted February 12 Share #18 Posted February 12 For loctite in cameras there I think not so easy for maintenance in future CLA's, because I have hasselblad 500CM and once per .... rolls of film it needs to be maintained. For me easy process to maintain by my self and time to time found loose screws in gearing and in maintenance documentation no treadlock recommendations because if something happens when broke screw head more incoming problems here . Example from CLA of 500ELM bought from ebay EXC+++ and all gearing screws was totally loose, but just clean lubricate and tighten them and after time to time CLA is must. Another example my canon R5 and other friends same models and as I remember on R6 was the same when hot shoe simply drops of with flash in my experience was two times for R5 and it takes 1-2 weeks in service. What I want to say, all cameras have specific checkpoints where needs attention and we are not alone with only leica. Welcome, dear visitor!
