Really excellent, very well done step by step tutorial. It has given me the confidence to try this myself on my own copy. Thank you so much and keep up the good work.

Thank you so much for posting this on KZfaq it’s help me no end and now my lens is focusing buttery, smooth.

Excellent tutorial.

Greetings from Orlando, Florida. Thank you for this useful video, my Russian friend!!!!

really appreciate your instructions!!!

Thank You for another great cleaning tutorial. I now know how to service my lens, cheers.

Excellent, and simple explanation for lubricating my 44-2, thank you.

Thanks for this great tutorial. I managed to lubricate my pristine (100% original) Helios-44. So now it's almost like new - in every sense. Like a time capsule! :)

~4 years ago I bought one of these Helios 44 with a stuck focusing ring,it was really hard to turn, it was grease problems just like in this video. Since I am not a professional and I got the lens for really cheap price, I though what the heck, why cant I just wash it of with WD-40? So did I... Just removed the glass part and sprayed the WD40 inside of the barrel through the gaps visible.. Turned it forth and back for like ~10 mins, cleaned everything as much as I could, after that I applied couple droplets of a sewing machine oil on the barrel just to make a little moisten... So far 4 years have passed, the lens is good as new... Focusing helicoid moves perfectly, havent noticed anything negative... WD40 just melts the old grease, it looks like it dissolves in it like mud in the water. I am definitely not sure if what i did was right and wont damage the lens mechanism, but I am pretty sure if it did I would have already noticed something bad about it..

Thanks so much! The wd-40 in the syringe is a great idea. Those screws really like to crumble up and become lodged inside with no way to get them out. terribly frustrating.

Good job. I really appreciated your teachings. Thank you

Thank you for this video and also the one on oily aperture blades.

Amazing work... Cheers

This video helped me a lot - thank you! :)

Thank you very much for the very good video.

this is a great video!

I also have the same beautiful Silver lens with very stiff focus. I'm a bit afraid to lubricate it, but I think I have to, because the lens is almost unusable now, because it's so stiff

Hi again, RFH - I sent my 44M 58/2 lens off to a guy in the UK who sells lots of old lenses and also does repairs on these fabulous Helios lenses (and others too, of course, he doesn't specialise in specific lenses). I should have the lens back from him this week with oil/grease-free iris/aperture blades and a fully clicking aperture ring too. :) I WOULD like all the powder paint removed too, (to 'silver' it), but I figured that was purely a cosmetic thing and wasn't very important AND there'd be no guarantee he'd do a perfect job of it. :D Thanks for your Helios lens videos, nice one. Spasiba. :) By the way - your English is very good - DEFINITELY better than my Russian. :)

Nice! Keep up the good work!

Very useful video especially helpful when taking the helicoid apart. I have a Tair-3 A 300mm f4 with similar problems. I cannot find a guide anywhere to dismantle it. I'm loathe to throw it away. Any ideas?

Nice video! Now I understand how to fix my lens! I will try it when I have spare time! There are too few video talk about Volna 9 in the internet. Maybe you can make some video to talk about how to fix/lubricate this lens :)

Tried it, but unfortunately I just couldn't unscrew the last screw on the black ring. But I went ahead and cleaned and re-applied grease wherever I could and I'm very happy with the results.

Brilliant and detailed thank you for those of us who own this amazing lens

Great movie, clear & helpful - thank you! BTW, the lubricant WD40 is prononunced 'double you' dee forty, not 'vee dee forty'. 'Vee' is a different letter! The product's full name is Water Dispersant (formula number) 40, abbreviated to WD40 :-)

Thank you for making this! I think this should also work for the Carl Zeiss Jena Biotar 58 as this is a copy of it!

Thank you!!!!!!! 👍👍👍👍

Many thanks for this video, very helpfull. Can you please do the same with the Jupiters 135mm ? Thanks

Very usefull thanks!

nice

Хорошо!!

Hey, im planning to clean and reapply the grease so i was wondering what grease could i use as an alternative to buying it from the local shops? Greetings from Croatia Tnx🙏

Hi, great video. You are clearly very skilled and I appreciate the knowledge you are imparting to us. I would like to try this but I cant unscrew the optical block from the focusing block - its on very tight, Any advice?

I've got Helios from 1982...is it the same assemble...

I have an Helios 44M 6 but I can not open the front cover because there are not 2 holes as in all the ones I see on You Tube videos. How do I remove the front lens to clean it?

Oh boy, I have to do this soon when my equipment arrives...I'm a bit apprehensive.

Awesome videos!!! Please do a jupiter 8 lubricate video

Thanks for this very helpful video. The 44 I bought had an extremely stiff focus ring, and while taking apart, when I got to the multi-thread ring, I couldn't get it back on, so I lost the position before I could mark it. I have just about managed to get it back on in a random position, and it seems like it works. Is there something that will not work properly if it is not in the correct position? I suppose there are only 5 or 6 different options to go through if I got it wrong, but so far it seems like it's fine, but I haven't had the chance to try it out extensively yet. Thanks

great videos, can you tell us what's the link to your shop? thank you

Thx for making the videos man, helped a lot :) One question: before I found your channel I've read/saw on others people channels they use Liqui Moly LM 50 Litho HT grease for lubrication. So I bought that and use it, but I'm not sure about it. It does make things smooth, but not very smooth. So I'm not sure if the lenses I have have such tight tolerances on their own or is the grease wrong. Do you know this grease, would you recommend it? TIA!

Hello. I regreased a Helios following this video and it worked perfectly. I’m now going to work on a Flektogon 20/4 and wondered if the disassembly is similar?

How is it in terms of separating and leaking onto aperture blades and stuff and is it very light or it gives some resistance ?How does it compare to JHT #10 in your opinion?

how much it coast if send you the lense to clean it ?

hi, can you please let me know where I can buy the same screwdriver set you have? I cannot seem to find a small enough screwdrivers

🍀🍀

Thanks a lot, but what kind of grease are you using to?

What Grade Grease did you use ? Grade 10 or grade 40?

Hello. I'm looking to clean and lubricate some Helios 44's with start beyonet mount . A couple the aperture button twist push mechanism is not fully working. . I hope to find some guidance somewhere before preceding blindly.

hi, how to clean and shine the tarnished yellowish aluminum ring?

Hello mate, you have used gun oil to lubricate a Helios 44M-6 in another video. I don't want to fully disassemble it and use grease...which type of gun oil can I use? There's Silicon oil and Water-based oil on Ebay...

what size is the syringe?

Where can i find these tools on amazon

Many thanks for the video! I followed your instructions and ended up with a butterly smooth Helios-44, which is nice! I do think I have made a mistake though: the focus ring will not go to 0,5m. Instead, it stops just before 0,55. The lens also has lost its sharpness. 😕 Hope you can tell me what I did wrong.

My optical block is stuck on the focusing part, cannot unscrew no matter how hard I try. Do you have any advice? I want to use WD-40 but I am nervous to since this is bad for the glass

My MMZ made helios 44 is not screwing out like you did, any help?

where csa i get screws for my lenses the 135 f4 helios

I just bought Zenit 3m with helios 44 but the diaphrame ring turns like junk and diaphrame has strong exploatation marks - to the point that bare metal is exposed and I think it may cause reflections inside the lense. Can i replace both ring and diaphrame with any other of 44 family?

i'm stuk at first step ! cannot unscrew the front, it is very well stuck...

What size screwdriver do you use? 0,8mm?

Co masz na smar stosuje?

Где можно приобрести такую отвертку от откручивания самых маленьких болтиков?

Please oil link

Aan alle Nederlanders die dit proberen: gebruik geen Kroon-oil lagervet zoals ik, want dat spul lijkt net lijm...

i did the same but something is wrong, i can focus 4 meters maximally, i lost the mark of the last ring but I could find the position where it was possible to screw the ring in, several times but with the same result. Can you help me, where is the problem, is possible to fix it?

Do you mean 13 blades...

WD40 is not a lubricant. It is a water displacer.
